Effetto di un packaging innovativo sulla qualità di nettarine

L’imballaggio alimentare si può definire come un sistema coordinato per disporre i beni per il trasporto, la distribuzione, la conservazione, la vendita e l’utilizzo. Uno dei materiali maggiormente impiegati, nell’industria alimentare, per la produzione di imballaggi sono le materie plastiche. Esse sono sostanze organiche derivanti da petrolio greggio, sono composti solidi allo stato finito, ma possono essere modellate allo stato fluido. Un imballaggio alimentare deve svolgere determinate funzioni tra cui: - contenimento del prodotto - protezione del prodotto da agenti esterni - logistica - comunicativa - funzionale - ecologica L'ultimo punto sopracitato è il principale problema delle materie plastiche derivanti dal petrolio greggio. Questi materiali sono difficilmente riciclabili perché spesso un imballaggio è composto da più materiali stratificati o perché si trova a diretto contatto con gli alimenti. Inoltre questi materiali hanno un lungo tempo di degradazione (da 100 a 1000 anni) che ne rendono difficile e costoso lo smaltimento. Per questo nell’ultimo decennio è cominciata la ricerca di un materiale plastico, flessibile alle esigenze industriali e nel contempo biodegradabile. Una prima idea è stata quella di “imitare la natura” cercando di replicare macromolecole già esistenti (derivate da amido e zuccheri) per ottenere una sostanza plastico-simile utilizzabile per gli stessi scopi, ma biodegradabile in circa sei mesi. Queste bioplastiche non hanno preso piede per l’alto costo di produzione e perché risulta impossibile riconvertire impianti di produzione in tutto il mondo in tempi brevi. Una seconda corrente di pensiero ha indirizzato i propri sforzi verso l’utilizzo di speciali additivi aggiunti in minima misura (1%) ai classici materiali plastici e che ne permettono la biodegradazione in un tempo inferiore ai tre anni. Un esempio di questo tipo di additivi è l’ECM Masterbatch Pellets che è un copolimero di EVA (etilene vinil acetato) che aggiunto alle plastiche tradizionali rende il prodotto finale completamente biodegradabile pur mantenendo le proprie caratteristiche. Scopo di questo lavoro di tesi è stato determinare le modificazioni di alcuni parametri qualitativi di nettarine di Romagna(cv.-Alexa®) confezionate-con-film-plastici-tradizionali-e-innovativi. I campioni di nettarine sono stati confezionati in cestini in plastica da 1 kg (sigillati con un film flow-pack macroforato) di tipo tradizionale in polipropilene (campione denominato TRA) o vaschette in polipropilene additivato (campione denominato BIO) e conservati a 4°C e UR 90-95% per 7 giorni per simulare un trasporto refrigerato successivamente i campioni sono stati posti in una camera a 20°C e U.R. 50% per 4 giorni al fine di simulare una conservazione al punto vendita. Al tempo 0 e dopo 4, 7, 9 e 11 giorni sono state effettuate le seguenti analisi: - coefficiente di respirazione è stato misurata la quantità di CO2 prodotta - indice di maturazione espresso come rapporto tra contenuto in solidi solubili e l’acidità titolabile - analisi di immagine computerizzata - consistenza della polpa del frutto è stata misurata attraverso un dinamometro Texture Analyser - contenuto in solidi totali ottenuto mediante gravimetria essiccando i campioni in stufa sottovuoto - caratteristiche sensoriali (Test Accettabilità) Conclusioni In base ai risultati ottenuti i due campioni non hanno fatto registrare dei punteggi significativamente differenti durante tutta la conservazione, specialmente per quanto riguarda i punteggi sensoriali, quindi si conclude che le vaschette biodegradabili additivate non influenzano la conservazione delle nettarine durante la commercializzazione del prodotto limitatamente ai parametri analizzati. Si ritiene opportuno verificare se il processo di degradazione del polimero additivato si inneschi già durante la commercializzazione della frutta e soprattutto verificare se durante tale processo vengano rilasciati dei gas che possono accelerare la maturazione dei frutti (p.e. etilene), in quanto questo spiegherebbe il maggiore tasso di respirazione e la più elevata velocità di maturazione dei frutti conservati in tali vaschette. Alimentary packaging may be defined as a coordinate system to dispose goods for transport, distribution, storage, sale and use. Among materials most used in the alimentary industry, for the production of packaging there are plastics materials. They are organic substances deriving from crude oil, solid compounds in the ended state, but can be moulded in the fluid state. Alimentary packaging has to develop determinated functions such as: - Product conteniment - Product protection from fieleders agents - logistic - communicative - functional - ecologic This last term is the main problem of plastic materials deriving from crude oil. These materials are hardly recyclable because a packaging is often composed by more stratified materials or because it is in direct contact with aliments. Beside these materials have a long degradation time(from 100 to 1000 years) that make disposal difficult and expensive. For this reason in the last decade the research for a new plastic material is begin, to make industrial demands more flexible and, at the same time, to make this material biodegradable: At first, the idea to “imitate the nature” has been thought, trying to reply macromolecules already existents (derived from amid and sugars) to obtain a similar-plastic substance that can be used for the same purposes, but it has to be biodegradable in about six months. These bioplastics haven’t more success bacause of the high production cost and because reconvert production facilities of all over the wolrd results impossible in short times. At second, the idea to use specials addictives has been thought. These addictives has been added in minim measure (1%) to classics plastics materials and that allow the biodegradation in a period of time under three years. An example of this kind of addictives is ECM Masterbatch Pellets which is a coplymer of EVA (Ethylene vinyl acetate) that, once it is added to tradizional plastics, make final product completely biodegradable however maintaining their own attributes. The objective of this thesis work has been to determinate modifications of some Romagna’s Nectarines’ (cv. Alexa®) qualitatives parameters which have been packaged-with traditional and innovative-plastic film. Nectarines’ samples have been packaged in plastic cages of 1 kg (sealed with a macro-drilled flow-pack film) of traditional type in polypropylene (sample named TRA) or trays in polypropylene with addictives (sample named BIO) and conservated at 4°C and UR 90-95% for 7 days to simulate a refrigerated transport. After that, samples have been put in a camera at 20°C and U.R. 50% for 4 days to simulate the conservation in the market point. At the time 0 and after 4, 7, 9 and 11 days have been done the following analaysis: - Respiration coefficient wherewith the amount CO2 producted has been misurated - Maturation index which is expressed as the ratio between solid soluble content and the titratable acidity - Analysis of computing images - Consistence of pulp of the fruit that has been measured through Texture Analyser Dynanometer - Content in total solids gotten throught gravimetry by the drying of samples in vacuum incubator - Sensorial characteristic (Panel Test) Consequences From the gotten results, the two samples have registrated no significative different scores during all the conservation, expecially about the sensorial scores, so it’s possible to conclude that addictived biodegradable trays don’t influence the Nectarines’ conservation during the commercialization of the product qualifiedly to analized parameters. It’s advised to verify if the degradation process of the addicted polymer may begin already during the commercialization of the fruit and in particular to verify if during this process some gases could be released which can accelerate the maturation of fruits (p.e. etylene), because all this will explain the great respiration rate and the high speed of the maturation of fruits conservated in these trays.

Evoluzione della qualità delle carni avicole durante la conservazione refrigerata

Lo studio ha lo scopo di valutare e confrontare l'efficienza del packaging in “LID” con atmosfera modificata a confronto con il confezionamento più tradizionale in “stretch” con atmosfera ordinaria, sulla shelf-life di diversi prodotti avicoli quali petti e sovracosce di pollo e fese di tacchino. A tal fine sui prodotti diversamente confezionati sono state valutate le variazioni di alcuni parametri qualitativi analizzando e confrontando alcuni aspetti tecnologici (pH, colore, texture, capacità di ritenzione idrica) durante un periodo di stoccaggio di 15 giorni in diverse condizioni di refrigerazione: durante i primi 3 giorni a 0-2°C, dal terzo al quindicesimo giorno a 6-8°C, al fine di simulare condizioni di abuso termico ed accelerare i fenomeni di deterioramento.

Analisi e ottimizzazione delle prestazioni e dell'affidabilità di una macchina per il packaging di prodotti igienico-sanitari

L’oggetto di studio di questo lavoro, svolto presso l’azienda Vire Automation del gruppo Bucci Industries di Faenza, è una macchina per il packaging di prodotti igienico-sanitari, più precisamente pannolini baby. Dopo una prima indagine di mercato svolta con l’aiuto dei commerciali dell’azienda, si sono ipotizzate una serie di soluzioni tecniche per migliorare il funzionamento e le prestazioni della macchina. Tramite uno strumento detto Casa della qualità si sono evidenziate le soluzioni tecniche che risultano più apprezzate dal mercato e per questo posseggono una maggior priorità di realizzazione. Si è intervenuti su di un gruppo funzionale per lo spostamento orizzontale del prodotto che agisce superiormente rispetto al pianale di processo e sul trasporto pioli che invece agisce per ostacolo tra cilindri di acciaio ed i prodotti. In particolare per il primo si è realizzato un apposito studio delle grandezze cinematiche in gioco e, dopo una progettazione 3D, si sono stimate le coppie motrici richieste dal nuovo asse che è risultato vantaggioso rispetto al precedente. Per il secondo invece, vista l’esigenza di ottenere un gruppo rifasatore che permettesse alla macchina di funzionare correttamente nonostante i ritardi di arrivo dei prodotti dalla linea di produzione, si è realizzata una nuova gestione logica del gruppo per sopperire alla peggior condizione di funzionamento verificabile e si è riprogettato il gruppo per dotarlo delle nuove necessarie caratteristiche.

Mesure des comportements des mentors en contexte de mentorat scolaire et liens entre ces comportements, la qualité de la relation de mentorat et l’ajustement des protégés

Les résultats d’études récentes suggèrent que certains comportements de soutien des mentors pourraient augmenter les bénéfices du mentorat scolaire. Cependant, peu d’outils validés sont disponibles dans la littérature pour mesurer ces comportements. Il est aussi convenu que l’efficacité du mentorat scolaire dépend de la qualité de la relation tissée entre le mentor et son protégé, laquelle serait tributaire d’un ensemble de facteurs, dont les comportements du mentor. Néanmoins, encore une fois très peu d’études empiriques ont tenté d’identifier les patrons de comportements des mentors les plus susceptibles d’influencer la relation de mentorat et l’ajustement des protégés. La présente thèse poursuit deux objectifs, soit de construire et valider un outil de mesure des comportements de soutien des mentors oeuvrant en contexte de mentorat scolaire, puis d’explorer les liens entre des comportements de structure et de soutien des mentors, la relation de mentorat et l’ajustement des protégés. L’échelle de comportements des mentors (ECM) a été développée en s’inspirant des prémisses du modèle sociomotivationnel du mentorat (Larose & Tarabulsy, 2014). Deux cent cinquante-trois étudiants du collégial participant à un programme de mentorat scolaire d’une durée de huit mois ont complété une version expérimentale de l’ECM ainsi que différentes mesures de la qualité de la relation de mentorat à deux temps de leur participation au programme. Les résultats montrent que le questionnaire possède de bons coefficients de cohérence interne et une structure factorielle adéquate, à l’exception du facteur soutien à l’autonomie. De plus, trois des dimensions de l’ECM prédisent la qualité de la relation de mentorat et la perception d’utilité de l’intervention. Des recommandations pour l’utilisation et l’amélioration de l’ECM sont proposées. Sur la base des évaluations des protégés à l’ECM (Brodeur et al., 2015), quatre regroupements distincts de comportements de mentors ont été identifiés : Optimal, Suffisant, Contrôlant, et Inadéquat. Les résultats montrent que plus les mentors ont fait preuve de soutien et de structure, plus les protégés ont évalué positivement la relation et l’utilité du mentorat, sauf pour les profils Optimal et Contrôlant. Par ailleurs, uniquement l’ajustement social des protégés a différé du groupe contrôle, et ce proportionnellement à la quantité de soutien et de structure prodigués par les mentors. D’autre part, il est discuté de l’impact de l’ajustement initial des protégés sur les comportements des mentors. Des implications théoriques et pratiques des résultats des deux articles sont présentées. Mots-clés : mentorat scolaire, comportements des mentors, validation de questionnaire, qualité de la relation de mentorat, ajustement des protégés.

Bioengineered 3D platform to explore cell-ECM interactions and drug resistance of epithelial ovarian cancer cells

The behaviour of cells cultured within three-dimensional (3D) structures rather than onto two-dimensional (2D) culture plastic more closely reflects their in vivo responses. Consequently, 3D culture systems are becoming crucial scientific tools in cancer cell research. We used a novel 3D culture concept to assess cell-matrix interactions implicated in carcinogenesis: a synthetic hydrogel matrix equipped with key biomimetic features, namely incorporated cell integrin-binding motifs (e.g. RGD peptides) and the ability of being degraded by cell-secreted proteases (e.g. matrix metalloproteases). As a cell model, we chose epithelial ovarian cancer, an aggressive disease typically diagnosed at an advanced stage when chemoresistance occurs. Both cell lines used (OV-MZ-6, SKOV-3) proliferated similarly in 2D, but not in 3D. Spheroid formation was observed exclusively in 3D when cells were embedded within hydrogels. By exploiting the design flexibility of the hydrogel characteristics, we showed that proliferation in 3D was dependent on cell-integrin engagement and the ability of cells to proteolytically remodel their extracellular microenvironment. Higher survival rates after exposure to the anti-cancer drug paclitaxel were observed in cell spheroids grown in hydrogels (40-60%) compared to cell monolayers in 2D (20%). Thus, 2D evaluation of chemosensitivity may not reflect pathophysiological events seen in patients. Because of the design flexibility of their characteristics and their stability in long-term cultures (28 days), these biomimetic hydrogels represent alternative culture systems for the increasing demand in cancer research for more versatile, physiologically relevant and reproducible 3D matrices.

Development of a high-speed sensing and detection system for automatic removal of packages with leaky seals from a high-speed food processing and packaging line

Contamination of packaged foods due to micro-organisms entering through air leaks can cause serious public health issues and cost companies large amounts of money due to product recalls, consumer impact and subsequent loss of market share. The main source of contamination is leaks in packaging which allow air, moisture and microorganisms to enter the package. In the food processing and packaging industry worldwide, there is an increasing demand for cost effective state of the art inspection technologies that are capable of reliably detecting leaky seals and delivering products at six-sigma. The new technology will develop non-destructive testing technology using digital imaging and sensing combined with a differential vacuum technique to assess seal integrity of food packages on a high-speed production line. The cost of leaky packages in Australian food industries is estimated close to AUD $35 Million per year. Contamination of packaged foods due to micro-organisms entering through air leaks can cause serious public health issues and cost companies large sums of money due to product recalls, compensation claims and loss of market share. The main source of contamination is leaks in packaging which allow air, moisture and micro-organisms to enter the package. Flexible plastic packages are widely used, and are the least expensive form of retaining the quality of the product. These packets can be used to seal, and therefore maximise, the shelf life of both dry and moist products. The seals of food packages need to be airtight so that the food content is not contaminated due to contact with microorganisms that enter as a result of air leakage. Airtight seals also extend the shelf life of packaged foods, and manufacturers attempt to prevent food products with leaky seals being sold to consumers. There are many current NDT (non-destructive testing) methods of testing the seal of flexible packages best suited to random sampling, and for laboratory purposes. The three most commonly used methods are vacuum/pressure decay, bubble test, and helium leak detection. Although these methods can detect very fine leaks, they are limited by their high processing time and are not viable in a production line. Two nondestructive in-line packaging inspection machines are currently available and are discussed in the literature review. The detailed design and development of the High-Speed Sensing and Detection System (HSDS) is the fundamental requirement of this project and the future prototype and production unit. Successful laboratory testing was completed and a methodical design procedure was needed for a successful concept. The Mechanical tests confirmed the vacuum hypothesis and seal integrity with good consistent results. Electrically, the testing also provided solid results to enable the researcher to move the project forward with a certain amount of confidence. The laboratory design testing allowed the researcher to confirm theoretical assumptions before moving into the detailed design phase. Discussion on the development of the alternative concepts in both mechanical and electrical disciplines enables the researcher to make an informed decision. Each major mechanical and electrical component is detailed through the research and design process. The design procedure methodically works through the various major functions both from a mechanical and electrical perspective. It opens up alternative ideas for the major components that although are sometimes not practical in this application, show that the researcher has exhausted all engineering and functionality thoughts. Further concepts were then designed and developed for the entire HSDS unit based on previous practice and theory. In the future, it would be envisaged that both the Prototype and Production version of the HSDS would utilise standard industry available components, manufactured and distributed locally. Future research and testing of the prototype unit could result in a successful trial unit being incorporated in a working food processing production environment. Recommendations and future works are discussed, along with options in other food processing and packaging disciplines, and other areas in the non-food processing industry.

Anisotropy of articular cartilage reflects the ECM gradient architecture : Hough-Radon Transform Analysis

Tissue-specific extracellular matrix (ECM) is known to be an ideal bioscaffold to inspire the future of regenerative medicine. It holds the secret of how nature has developed such an organization of molecules into a unique functional complexity. This work exploited an innovative image processing algorithm and high resolution microscopy associated with mechanical analysis to establish a correlation between the gradient organization of cartiligous ECM and its anisotropic biomechanical response. This was hypothesized to be a reliable determinant that can elucidate how microarchitecture interrelates with biomechanical properties. Hough-Radon transform of the ECM cross-section images revealed its conformational variation from tangential interface down to subchondral region. As the orientation varied layer by layer, the anisotropic mechanical response deviated relatively. Although, results were in good agreement (Kendall's tau-b > 90%), there were evidences proposing that alignment of the fibrous network, specifically in middle zone, is not as random as it was previously thought.

Prognostic significance of IGF and ECM induced signalling proteins in breast cancer patients

Breast cancer is a leading contributor to the burden of disease in Australia. Fortunately, the recent introduction of diverse therapeutic strategies have improved the survival outcome for many women. Despite this, the clinical management of breast cancer remains problematic as not all approaches are sufficiently sophisticated to take into account the heterogeneity of this disease and are unable to predict disease progression, in particular, metastasis. As such, women with good prognostic outcomes are exposed to the side effects of therapies without added benefit. Furthermore, women with aggressive disease for whom these advanced treatments would deliver benefit cannot be distinguished and opportunities for more intensive or novel treatment are lost. This study is designed to identify novel factors associated with disease progression, and the potential to inform disease prognosis. Frequently overlooked, yet common mediators of disease are the interactions that take place between the insulin-like growth factor (IGF) system and the extracellular matrix (ECM). Our laboratory has previously demonstrated that multiprotein insulin-like growth factor-I (IGF-I): insulin-like growth factor binding protein (IGFBP): vitronectin (VN) complexes stimulate migration of breast cancer cells in vitro, via the cooperative involvement of the insulin-like growth factor type I receptor (IGF-IR) and VN-binding integrins. However, the effects of IGF and ECM protein interactions on the dissemination and progression of breast cancer in vivo are unknown. It was hypothesised that interactions between proteins required for IGF induced signalling events and those within the ECM contribute to breast cancer metastasis and are prognostic and predictive indicators of patient outcome. To address this hypothesis, semiquantitative immunohistochemistry (IHC) analyses were performed to compare the extracellular and subcellular distribution of IGF and ECM induced signalling proteins between matched normal, primary cancer, and metastatic cancer among archival formalin-fixed paraffin-embedded (FFPE) breast tissue samples collected from women attending the Princess Alexandra Hospital, Brisbane. Multivariate Cox proportional hazards (PH) regression survival models in conjunction with a modified „purposeful selection of covariates. method were applied to determine the prognostic potential of these proteins. This study provides the first in-depth, compartmentalised analysis of the distribution of IGF and ECM induced signalling proteins. As protein function and protein localisation are closely correlated, these findings provide novel insights into IGF signalling and ECM protein function during breast cancer development and progression. Distinct IGF signalling and ECM protein immunoreactivity was observed in the stroma and/or in subcellular locations in normal breast, primary cancer and metastatic cancer tissues. Analysis of the presence and location of stratifin (SFN) suggested a causal relationship in ECM remodelling events during breast cancer development and progression. The results of this study have also suggested that fibronectin (FN) and ¥â1 integrin are important for the formation of invadopodia and epithelial-to-mesenchymal transition (EMT) events. Our data also highlighted the importance of the temporal and spatial distribution of IGF induced signalling proteins in breast cancer metastasis; in particular, SFN, enhancer-of-split and hairy-related protein 2 (SHARP-2), total-akt/protein kinase B 1 (Total-AKT1), phosphorylated-akt/protein kinase B (P-AKT), extracellular signal-related kinase-1 and extracellular signal-related kinase-2 (ERK1/2) and phosphorylated-extracellular signal-related kinase-1 and extracellular signal-related kinase-2 (P-ERK1/2). Multivariate survival models were created from the immunohistochemical data. These models were found to fit well with these data with very high statistical confidence. Numerous prognostic confounding effects and effect modifications were identified among elements of the ECM and IGF signalling cascade and corroborate the survival models. This finding provides further evidence for the prognostic potential of IGF and ECM induced signalling proteins. In addition, the adjusted measures of associations obtained in this study have strengthened the validity and utility of the resulting models. The findings from this study provide insights into the biological interactions that occur during the development of breast tissue and contribute to disease progression. Importantly, these multivariate survival models could provide important prognostic and predictive indicators that assist the clinical management of breast disease, namely in the early identification of cancers with a propensity to metastasise, and/or recur following adjuvant therapy. The outcomes of this study further inform the development of new therapeutics to aid patient recovery. The findings from this study have widespread clinical application in the diagnosis of disease and prognosis of disease progression, and inform the most appropriate clinical management of individuals with breast cancer.

The Gold Coast marine precinct : pre-packaging entrepreneurship

We investigate the evolving quality of entrepreneurship in the Gold Coast Marine Precinct, a purpose-built industrial district in Southeast Queensland, Australia. Our findings are that the environment in the Precinct can be conducive to a better quality of entrepreneurship than may be feasible for firms in other settings; that a successful industrial district can be created artificially, with appropriate social relationships evolving afterwards; and that improvements in information and communications technology have undermined some aspects of traditional behaviour in the Precinct, but the essential nature of internal relationships remains intact.

Pre-packaging preschool literacy: What drives early childhood teachers to use commercially produced phonics programs in prior to school settings

Language-rich environments are key to overall quality in early childhood settings, including frequent child–staff interactions around picture books and dramatic play. In a language-rich environment, explicit teaching of literacy concepts, such as phonics, is embedded in authentic and meaningful situations where alphabet letters and sounds are taught in a context meaningful to the child. Recent research, however, suggests that the use of commercial pre-packaged phonics programs (such as Letterland and Jolly Phonics) is widespread in prior to school settings in Sydney, Australia. Little is known about why early childhood teachers choose to use such programs with children aged five and under. In the present study, thematic analysis of data from interviews with five early childhood teachers using commercial phonics programs found that their reasons were pragmatic rather than pedagogical. Motivations included the idea that the programs reduced their workload, provided tangible evidence to parents of their child’s ‘school readiness’, and served as a marketing tool to attract parents. Further analysis found that the teachers were unable to articulate what phonics and phonological awareness are and how they are learnt in early childhood.

Plain packaging for the Pacific Rim: The Trans-Pacific Partnership and tobacco control

Big Tobacco has been engaged in a dark, shadowy plot and conspiracy to hijack the Trans-Pacific Partnership Agreement (TPP) and undermine tobacco control measures – such as graphic health warnings and the plain packaging of tobacco products... In the context of this heavy lobbying by Big Tobacco and its proxies, this chapter provides an analysis of the debate over trade, tobacco, and the TPP. This discussion is necessarily focused on the negotiations of the free trade agreement – the shadowy conflicts before the finalisation of the text. This chapter contends that the trade negotiations threaten hard-won gains in public health – including international developments such as the WHO Framework Convention on Tobacco Control, and domestic measures, such as graphic health warnings and the plain packaging of tobacco products. It maintains that there is a need for regional trade agreements to respect the primacy of the WHO Framework Convention on Tobacco Control. There is a need both to provide for an open and transparent process regarding such trade negotiations, as well as a due and proper respect for public health in terms of substantive obligations. Part I focuses on the debate over the intellectual property chapter of the TPP, within the broader context of domestic litigation against Australia’s plain tobacco packaging regime and associated WTO disputes. Part II examines the investment chapter of the TPP, taking account of ongoing investment disputes concerning tobacco control and the declared approaches of Australia and New Zealand to investor-state dispute settlement. Part III looks at the discussion as to whether there should be specific text on tobacco control in the TPP, and, if so, what should be its nature and content. This chapter concludes that the plain packaging of tobacco products – and other best practices in tobacco control – should be adopted by members of the Pacific Rim.
