Conservação pós-colheita de banana cv. nanicão climatizada e comercializada em Cuiabá - MT e região

A banana cv. Nanicão é a principal cultivar comercializada nos mercados brasileiro e mundial. A maior parte dessa cultivar comercializada no Estado de Mato Grosso vem de outros Estados, embora existam condições edafoclimáticas para ser auto-suficiente na produção dessa cultivar e inclusive atender a outros mercados. O objetivo deste trabalho foi verificar as condições da climatização da banana cv. Nanicão e sua influência na conservação pós-colheita de frutos produzidos no Estado de Mato Grosso (MT) e procedentes do Estado de Santa Catarina (SC). Foram acompanhadas 12 caixas de banana cv. Nanicão, pesando em torno de 21 kg cada, colhidas em pomar comercial do município de Campo Verde-MT, e também 12 caixas oriundas de SC. Anteriormente à climatização e durante todo o período de vida útil dos frutos, foram monitoradas diariamente a temperatura e a umidade relativa do ambiente, a evolução da coloração dos frutos e a perda de peso destes, assim como o teor de sólidos solúveis totais e de acidez potenciométrica nos frutos verdes e maduros. Verificou-se o maior período de vida útil da banana de SC, 3 dias após a retirada da câmara de climatização, apresentando-se totalmente amarela e com valor máximo de 7,07% de perda de peso dos frutos. A banana cv. Nanicão produzida no MT atingiu valores de perda de peso 5,69% no 2º dia, quando após esse período, não estaria mais própria para a comercialização, atingindo coloração amarelo-pálida. Altos índices de perdas foram detectados no período pós-colheita da banana-'Nanicão', representados principalmente por danos mecânicos na procedente de SC e por danos fisiológicos (despencamento) na banana de MT. O despencamento pode estar relacionado com a falta de circulação eficiente do etileno, da exaustão e umidade relativa baixa, 65% em média, durante a climatização. Nos teores de açúcares e de acidez dos frutos, a banana do MT apresentou valores levemente superiores de acidez, o que favorece o seu sabor quando relacionado com os teores de açúcares.

Principal components analysis for quality evaluation of cooled banana 'Nanicão' in different packing

This work aims determinate the evaluation of the quality of 'Nanicão' banana, submitted to two conditions of storage temperature and three different kinds of package, using the technique of the Analysis of Principal Components (ACP), as a basis for an Analysis of Variance. The fruits used were 'Nanicão' bananas, at ripening degree 3, that is, more green than yellow. The packages tested were: "Torito" wood boxes, load capacity: 18 kg; "½ box" wood boxes, load capacity: 13 kg; and cardboard boxes, load capacity: 18 kg. The temperatures assessed were: room temperature (control); and (13±1ºC), with humidity controlled to 90±2,5%. Fruits were discarded when a sensory analysis determined they had become unfit for consumption. Peel coloration, percentages of imperfection, fresh mass, total acidity, pH, total soluble solids and percentages of sucrose were assessed. A completely randomized design with a 2-factorial treatment structure (packing X temperature) was used. The obtained data were analyzed through a multivariate analysis known as Principal Components Analysis, using S-plus 4.2. The conclusion was that the best packages to preserve the fruit were the ½ box ones, which proves that it is necessary to reduce the number of fruits per package to allow better ventilation and decreases mechanical injuries and ensure quality for more time.

Avaliação econômica das perdas de banana no mercado varejista: um estudo de caso

O objetivo do presente estudo foi a determinação das perdas físicas e econômicas de banana em diferentes equipamentos varejistas na Cidade de Botucatu - SP e suas possíveis causas. Os equipamentos foram sorteados aleatoriamente. As informações foram coletadas através da aplicação de questionário para a determinação das perdas de três variedades de banana. O resultado mostrou perda global de 39 toneladas, correspondente a 11,1% da quantidade comercializada, sendo 10,5% em supermercados, 15,0% em quitandas/sacolões e 10,6% em feiras livres. O valor total das perdas anuais atingiu R$ 35.038,00, em valores de maio de 2002. A manipulação excessiva do cliente, excedente de oferta, uso de embalagem inadequada e baixa qualidade da fruta foram as principais causas de perdas. Conclui-se pela necessidade de conscientização do cliente, do uso de embalagens plásticas e de cuidados no manuseio da fruta durante toda pós-colheita.

Distribution systems of the food sector in Russia: the perspective of Finnish food industry

Finnish food producers' trade with Russia has experienced profound changes since the collapse of the Soviet Union. Simultaneously, the distribution systems of foodstuffs have changed remarkably. This study sheds some light into these changes and analyses the current situation in distribution systems of foodstuffs in Russia. In addition, the study discusses the possibilities of Finnish food producers to get more of their products to the shelves of Russian food retail stores. Before the 1998 financial crisis, the import of foreign foodstuffs was booming in Russia due to the overvalued rouble. As a result of the financial crisis, food import collapsed. The export of Finnish foodstuffs to Russia has been slowly recovering during the past few years, but in the most important product categories the pre-crisis levels have so far not been reached and maybe will not be reached. In certain product categories the growth has been only marginal. It seems that starting localproduction will become increasingly important in the future. This is further encouraged by the fact that Russian consumers favour domestic food products. Russian consumers are very price conscious and demand quality in food products. The perceived price-quality ratio is an important criterion in the purchase decision.The majority of foodstuff retail is still conducted via unorganised forms of trade (e.g. kiosks and marketplaces) but modern retail chains are developing at a fast pace in Russia. They are also expected to dominate the retail trade in foodstuffs over the unorganised forms of trade in the future. This will change the distribution systems as well. The retail chains are trying to shorten the distribution chain, similarly to what has been seen in the Western countries. This together with the strengthening of retail chains is likely to shrink the role of wholesalers, as the chains increasingly want to work directly with the producers. Many large retail chains are acquiring or have already acquired a distribution centre or centres in order to boost efficiency and control the flow of products. The strengthening of the retail chains also gives them power in negotiations, which the producers and distributors have to adjust to. For example store entry fees and retail chains' own private label products pose challenges to the food producers. In the food production sector the competition is fierce, as large Russianand foreign producers want to ensure their piece of the market. The largest producers utilise their size: they invest in big marketing campaigns and are willing to pay high entry fees to retail chains in order to secure a place on the store shelves and to build a strong brand in Russia. This complicates the situation from the viewpoint of small producers. Currently, the most popular type of distribution system among the interviewed Finnish food producers is based on a network of local distributors. There is, however, a strong consensus on the importanceof starting local production in order to be a serious actor in Russia in the future. Factors that hinder the starting of local production include the lack of local infrastructure and qualified staff, and the low risk tolerance of Finnish firms. Major barriers for entry in Russia are the actions of authorities, fierce competition, fragmented market and Finnish producers' heavy production costs. The suggested strategies for increasing the market share include focusing geographically or segment-wise, introducing new products, starting local production, andcooperation between Finnish producers. Smallness was one reason why Finnish producers had to cut down their operations in Russia due to the 1998 crisis. Smaller producers had fewer resources to tolerate losses during the period of crisis. Smallness is reflected also on trade negotiations with retail chains and distributors. It makes it harder to cope with the store entry fees and to differentiatefrom the mass of products propped up by expensive advertising. Finally, it makes it harder for Finnish producers to start or expand local production, as it is more difficult for a small producer to get financing and to tolerate the increased risks. Compensating for the smallness might become the crucial factor determining the future success of Finnish food producers in the Russian market.

Value added logistics in supply and demand chain. Smile. Part 2. eBusiness in a service business. Case: A maintenance and operations network in forest industry

VVALOSADE is a research project of professor Anita Lukka's VALORE research team in the Lappeenranta University of Technology. The VALOSADE includes the ELO technology program of Tekes. SMILE is one of four subprojects of the VALOSADE. The SMILE study focuses on the case of the company network that is composed of small and micro-sized mechanical maintenance service providers and forest industry as large-scale customers. The basic principle of the SMILE study is the communication and ebusiness in supply and demand networks. The aim of the study is to develop ebusiness strategy, ebusiness model and e-processes among the SME local service providers, and onthe other hand, between the local service provider network and the forest industry customers in a maintenance and operations service business. A literature review, interviews and benchmarking are used as research methods in this qualitative case study. The first SMILE report, 'Ebusiness between Global Company and Its Local SME Supplier Network', concentrated on creating background for the SMILE study by studying general trends of ebusiness in supply chains and networks of different industries. This second phase of the study concentrates on case network background, such as business relationships, information systems and business objectives; core processes in maintenance and operations service network; development needs in communication among the network participants; and ICT solutions to respond needs in changing environment. In the theory part of the report, different ebusiness models and frameworks are introduced. Those models and frameworks are compared to empirical case data. From that analysis of the empirical data, therecommendations for the development of the network information system are derived. In process industry such as the forest industry, it is crucial to achieve a high level of operational efficiency and reliability, which sets up great requirements for maintenance and operations. Therefore, partnerships or strategic alliances are needed between the network participants. In partnerships and alliances, deep communication is important, and therefore the information systems in the network also are critical. Communication, coordination and collaboration will increase in the case network in the future, because network resources must be optimised to improve competitive capability of the forest industry customers and theefficiency of their service providers. At present, ebusiness systems are not usual in this maintenance network. A network information system among the forest industry customers and their local service providers actually is the only genuinenetwork information system in this total network. However, the utilisation of that system has been quite insignificant. The current system does not add value enough either to the customers or to the local service providers. At present, thenetwork information system is the infomediary that share static information forthe network partners. The network information system should be the transaction intermediary, which integrates internal processes of the network companies; the network information system, which provides common standardised processes for thelocal service providers; and the infomediary, which share static and dynamic information on right time, on right partner, on right costs, on right format and on right quality. This study provides recommendations how to develop this system in the future to add value to the network companies. Ebusiness scenarios, vision, objectives, strategies, application architecture, ebusiness model, core processes and development strategy must be considered when the network information system will be developed in the next development step. The core processes in the case network are demand/capacity management, customer/supplier relationship management, service delivery management, knowledge management and cash flow management. Most benefits from ebusiness solutions come from the electrifying of operational level processes, such as service delivery management and cash flow management.

Value added logistical support service Part 2. Outsourcing process of spare part logistics in metal industry

The aim of this research study was to find out guidelines for outsourcing of logistics processes. The study was outlined to spare parts and `business-to-business' (B2B) markets in metal industry. This study can be applied as a manual for outsourcing especially warehousing and transportation activities. The study also touches other important areas of spare part logistics like manufacturing, customer service, procurement, quality control, reverse and recycling logistics, logistics technologies and valueadded services. The method of study consisted of three areas. Firstly exchanging views with logistics experts in participating companies, and secondly compiling material based on author's practical experience in logistics business with several international and domestic logistics service providers and vendors. Thirdlythe study includes also references to literature material. Due to the fact thatthe outsourcing of logistics functions can be handled widely and from differentpoint of views, in this study it is concentrated mainly on giving general levelguidelines for defining logistics strategy, hints both for tendering process and implementation project, and not forgetting the aftercare of business partnership.

Aspects on Process Engineering in the Finnish Pulp and Paper Industry : Thesis for the Degree of Licentiate in Science of Technology

Process development will be largely driven by the main equipment suppliers. The reason for this development is their ambition to supply complete plants or process systems instead of single pieces of equipment. The pulp and paper companies' interest lies in product development, as their main goal is to create winning brands and effective brand management. Design engineering companies will find their niche in detail engineering based on approved process solutions. Their development work will focus on increasing the efficiency of engineering work. Process design is a content-producing profession, which requires certain special characteristics: creativity, carefulness, the ability to work as a member of a design team according to time schedules and fluency in oral as well as written presentation. In the future, process engineers will increasingly need knowledge of chemistry as well as information and automation technology. Process engineering tools are developing rapidly. At the moment, these tools are good enough for static sizing and balancing, but dynamic simulation tools are not yet good enough for the complicated chemical reactions of pulp and paper chemistry. Dynamic simulation and virtual mill models are used as tools for training the operators. Computational fluid dynamics will certainlygain ground in process design.

Challenges in packaging waste management: A case study in the fast food industry

The main research problem of this thesis is to find out the means of promoting the recovery of packaging waste generated in thefast food industry. The recovery of packaging waste generated in the fast food industry is demanded by the packaging waste legislation and expected by the public. The means are revealed by the general factors influencing the recovery of packaging waste, analysed by a multidisciplinary literature review and a case study focusing on the packaging waste managementof McDonald's Oy operating in Finland. The existing solid waste infrastructure does not promote the recovery ofpackaging waste generated in the fast food industry. The theoretical recovery rate of the packaging waste is high, 93 %, while the actual recovery rate is only 29 % consisting of secondary packaging manufactured from cardboard. The total recovery potential of packaging waste is 64 %, resulting in 1 230 tonnes ofrecoverable packaging waste. The achievable recovery potential of 33 %, equalling 647 tonnes of packaging waste could be recovered, but is not recovered mainly because of non-working waste management practises. The theoretical recovery potential of 31 %, equalling 583 tonnes of packaging waste can not be recovered by the existing solid waste infrastructure because of the obscure status of commecial waste, the improper operation ofproducer organisations, and the municipal autonomy. The sorting experiment indicated that it is possible to reach the achievable recovery potential inthe existing solid waste infrastructure. The achievement is promoted by waste producer -oriented waste management practises. The theoretical recovery potential can be reached by increasing the consistency of the solid waste infrastructure through governmental action.

Marketing de banana: preferências do consumidor quanto aos atributos de qualidade dos frutos

O Brasil produz aproximadamente seis milhões de toneladas por ano de banana (Musa spp.), com consumo médio da ordem de 35 kg/ habitante / ano. A aceitação da banana deve-se, principalmente, a seus aspectos sensoriais, valor nutricional e conveniência. A identificação das necessidades e desejos dos clientes consiste em uma atividade crítica do marketing. O objetivo deste trabalho foi o de pesquisar as preferências do consumidor de um mercado local (município de Cruz das Almas - Estado da Bahia) considerando os atributos de qualidade dos frutos frescos de banana madura. A metodologia utilizada foi a da pesquisa descritiva por método estatístico. Os dados foram coletados por questionário, na forma de entrevista pessoal com 400 pessoas. Os atributos de qualidade (variáveis) questionados e avaliados foram relacionados com a aparência, cor, textura, aroma, sabor e vida útil esperada dos frutos de banana. De acordo com a preferência dos consumidores entrevistados, o fruto de banana maduro ideal deve apresentar características como: penca contendo 10 a 12 dedos (frutos), dedos de tamanho médio ou grande, diâmetro médio, quina presente, ausência de pintas pretas na casca, cor da polpa amarelo-clara ou média, textura firme, aroma e sabor de intensidade média, mediamente doce e vida útil de 7 a 10 dias em condição ambiente. O sabor, vida útil e aparência dos frutos de banana são considerados os mais importantes atributos na escolha ou compra da banana, segundo os consumidores entrevistados.

The effects of potentiallydisruptive technology on business model - a case study of new technologies in ICT industry

This study examines how firms interpret new, potentially disruptive technologies in their own strategic context. The work presents a cross-case analysis of four potentially disruptive technologies or technical operating models: Bluetooth, WLAN, Grid computing and Mobile Peer-to-peer paradigm. The technologies were investigated from the perspective of three mobile operators, a device manufacturer and a software company in the ICT industry. The theoretical background for the study consists of the resource-based view of the firm with dynamic perspective, the theories on the nature of technology and innovations, and the concept of business model. The literature review builds up a propositional framework for estimating the amount of radical change in the companies' business model with two middle variables, the disruptiveness potential of a new technology, and the strategic importance of a new technology to a firm. The data was gathered in group discussion sessions in each company. The results of each case analysis were brought together to evaluate, how firms interpret the potential disruptiveness in terms of changes in product characteristics and added value, technology and market uncertainty, changes in product-market positions, possible competence disruption and changes in value network positions. The results indicate that the perceived disruptiveness in terms ofproduct characteristics does not necessarily translate into strategic importance. In addition, firms did not see the new technologies as a threat in terms of potential competence disruption.

Origins of production errors and significance of employee empowerment in reducing production error amount in sheet metal fabricating industry

The market place of the twenty-first century will demand that manufacturing assumes a crucial role in a new competitive field. Two potential resources in the area of manufacturing are advanced manufacturing technology (AMT) and empowered employees. Surveys in Finland have shown the need to invest in the new AMT in the Finnish sheet metal industry in the 1990's. In this run the focus has been on hard technology and less attention is paid to the utilization of human resources. In manymanufacturing companies an appreciable portion of the profit within reach is wasted due to poor quality of planning and workmanship. The production flow production error distribution of the sheet metal part based constructions is inspectedin this thesis. The objective of the thesis is to analyze the origins of production errors in the production flow of sheet metal based constructions. Also the employee empowerment is investigated in theory and the meaning of the employee empowerment in reducing the overall production error amount is discussed in this thesis. This study is most relevant to the sheet metal part fabricating industrywhich produces sheet metal part based constructions for electronics and telecommunication industry. This study concentrates on the manufacturing function of a company and is based on a field study carried out in five Finnish case factories. In each studied case factory the most delicate work phases for production errors were detected. It can be assumed that most of the production errors are caused in manually operated work phases and in mass production work phases. However, no common theme in collected production error data for production error distribution in the production flow can be found. Most important finding was still that most of the production errors in each case factory studied belong to the 'human activity based errors-category'. This result indicates that most of the problemsin the production flow are related to employees or work organization. Development activities must therefore be focused to the development of employee skills orto the development of work organization. Employee empowerment gives the right tools and methods to achieve this.

Acúmulo e distribuição de nutrientes em banana 'Mysore' em desenvolvimento

Foram determinados o acúmulo de matérias fresca e seca e dos nutrientes N, P, K, Ca, Mg, Zn, Fe e Mn em bananas 'Mysore', desde a antese floral da primeira penca feminina até o completo amadurecimento. O desenvolvimento dos frutos foi lento até o 42º dia após a antese, acelerando-se posteriormente. A fase de acúmulo máximo de minerais coincidiu com a de acúmulo máximo de matéria fresca, ou seja, 112 dias após a antese. A ordem de exportação de macronutrientes pelos frutos, em seu estádio de máximo acúmulo de matéria fresca, expressa em kg t-1 de fruto fresco, foi 3,61 para K; 0,98 para N; 0,27 para Mg; 0,19 para P e 0,12 para Ca. Quanto aos micronutrientes, a ordem de exportação, expressa em g t-1 de fruto fresco, foi 7,92 para Mn; 5,99 para Fe e 2,92 para Zn. Em frutos plenamente desenvolvidos, à exceção de Ca, Mn e Zn, todos os nutrientes acumularam-se mais na polpa do que na casca.
