Avaliação das boas práticas de fabricação em linha de processamento de queijos Minas frescal e ricota

In order to assure the maintenance of foods integrity and quality, for avoiding chemical, physical or biological contamination, it is essential to follow the Good Manufacturing Practices (GMP). Among the techniques used for evaluating GMP there is the observational analysis carried out by means of a check-list form application. The present study evaluated the suitability of GMP in a dairy industry producer of Minas fresh and ricotta cheeses, located in São José do Rio Preto, SP, by applying a check-list form. A significant improvement in conformity was evidenced, increasing from 43% to 78%. Neither the blocks related to the handlers nor the existing documentation in the company showed any improvements, as poor conditions unchanged. All of the other evaluated blocks showed significant improvement after applying the GMPrelated corrective measures. Based on these findings, the observance of corrective measures by the dairy industry on dairy products, physical environment, GMP, and handlers training was crucial for assuring the improvements and to increase the product quality and consumers safety.

Histórico e aspectos tecnológicos do processamento da linguiça cuiabana

This paper reports the data on the cuiabana sausage historical aspect, and from the study performed on its technical/sensory characteristics. Four formulations of cuiabana-type sausage were prepared, varying the basic raw material (bovine, chicken and swine meats). For processing these sausages, the raw meats (beef, chicken and pork) were cut into cubes and together with the other ingredients (garlic, cheese, pepper and chives) they were weighed and homogenized. The resulting mixture was refrigerated for 24 hours for intensifying the flavor. Thereafter, it was stuffed into natural casings. These prepared samples were characterized on the physical-chemical profile and on the shelf life under refrigeration for over a seven day-storage in order to assess the microbiological contamination (total coliforms and fecal thermotolerant bacteria), sulphite-reducing clostridium, Salmonella spp., coagulase-positive Staphylococcus), and pH. The sensory evaluation and statistics analysis were carried out on the different types of laboratory- processed cuiabana sausage. Introducing over time changes in the cuiabana sausages formulation are positive factors; therefore, variations in the formulations it is feasible to get a better final product than that original one, and it might be resulted from the market demand.

Modelagem computacional das túnicas cardíacas para processamento e controle de qualidade

This paper considers a study of the anatomical features of the cardiac system and a three-dimensional model of the different tunics that comprise the heart wall, for processing and quality control of radiological images. The structures are built by the layer overlapping method, where a layer can be understood as a slice of the three-dimensional object. The pericardium, myocardium and endocardium were represented with three-dimensional cylinders and hexagons. The spatial arrangement of the cardiac system is determined by an background image of a real model, which values are defined according to the shape of the region and on the anatomical patients characteristics. The results are significant, considering the anatomical structures details, as well as the representation of the thicknesses of the regions of the heart wall. The validation of the anatomical model was accomplished through comparisons with dimensions obtained from a real model and allows verifying that the model is appropriate. The degree of representation will allow the verification of the influence of radiological parameters, morphometric peculiarities and stage of the diseases on the quality of the images, as well as on the performance of the Computer-Aided Diagnosis (CAD).

Em busca do sentido: uma análise das estratégias de processamento textual em O milagre das folhas, de Clarice Lispector

This text aims to elucidate the textual processing strategies that give meaning to chronicle "The miracle of the leaves", of Clarice Lispector (1920-1977). Therefore, it starts from the basic postulate that the meaning is not in the fabric or verbal imagery, but the meanings constructed from the elements of language that are there to meet with the reader (BRONCKART, 2009, p. 257). Justified this reading strategy, since the chronic Lispector reveals multiple meanings endowed with a language and dialogue. The text processing is discussed in terms of an audience potentially youthful element that assigns characteristics relevant to the understanding of the functioning of this type of text in relation to younger readers. To achieve the goal, we start from the assumption that chronic, being a literary text endowed with aesthetic validity, not only conveys a content, but recreates it, adding to it new meanings.

Degradabilidade e digestibilidade de híbridos de milho em função do estádio de colheita, tamanho de partícula e processamento por meio do esmagamento na ensilagem

During the process of silage corn, should take into consideration some aspects that will result in better utilization. The aim of this study was to evaluate the degradability of dry matter (DM), crude protein (CP), neutral detergent fiber (NDF) and starch digestibility and in vitro dry matter (DM) of silage corn hybrids due two textures, three stages of harvest, three particle sizes and processing by crushing. After harvesting and chipping, part of the material was crushed and then ensiled and sealed for 45 days. After opening the silos, analyzed the degradability in the incubation time of 20 hours using the technique in situ macro bag. The experimental design was a randomized split plot. The DM degradability was influenced only by the effect of stages of sampling used. The degradability of CP showed interaction between processing and particle size (Tp), noting that increased degradation due to processing. For NDF degradation significant interaction of factors, hybrid and processing, similar to the degradation of starch. The IVDMD was influenced by the effects of hybrid, stadium, Tp and processing. It can be concluded that benefits were higher with the use of processing associated with more advanced stages of harvest, in larger particle sizes.

Elaboração e implantação do sistema de análise de perigos e pontos críticos de controle no processamento de leite pasteurizado tipo A

Hazard analysis and critical control points (HACCP) is one of the main tools currently used to ensure safety, quality and integrity of foods. So, the aim of this study was to develop and implement the HACCP program in the processing of pasteurized grade A milk Checklists were used to assess on the level of the pre requisites programs and on the sanitary classification of the dairy industry and the results were used as references for the development of the HACCP system. A "decision tree" protocol was used for the identification of the critical control points (CCP). No physical or chemical CCP were identified, whereas pasteurization and packaging were considered biological CCP For these CCP, the limits for prevention, monitoring needs, corrective actions, critical limits and verification procedures were established. The pre requisites program was essential for the establishment of the system. The implementation of the HACCP for the processing of grade A pasteurized milk was efficient to control the biological hazards and enabled the product to comply with the legislation specifications and achieve safety.

Reflexos do processamento de cana-de-açúcar bisada na qualidade do açúcar VHP

The aim of this study was to compare the quality of clarifi ed juice and VHP (Very High Purity) sugar produced from “bisada” sugarcane and an early maturation variety, at the beginning of harvest. The experiment was conducted at Usina São Martinho S/A, Pradópolis,SP (Brazil). The process of juice clarifi cation and sugar production was conducted at the Laboratory of Technology of Sugar and Alcohol in the College of Agricultural and Veterinary Sciences at the Universidade Estadual Paulista (FCAV/UNESP), Jaboticabal (SP). The experimental design was randomized, and two varieties were used: SP83-2847 (“bisada” sugarcane) and RB855156 (early maturation), with twelve replications for technological analysis and four replications for sugar production. The clarifi cation process and the clarifi ed juice was evaluated in terms of settling rates, volume of sludge that formed, total soluble solids, pH, turbidity, total phenolic compounds, starch and color. The sugar was characterized regarding the percentage of apparent sugar, color, total phenolic compounds, starch, fi lterability, humidity and safety factor. It was verifi ed that the processing of the juice clarifi cation was not affected by the processing of the “bisada” sugarcane. However, the clarifi ed juice from the SP83-2847 variety had a more intense color and a higher total soluble solids value. The sugar produced from the “bisada” sugarcane presented similar quality to the early maturation variety. It was concluded that the processing of “bisada” sugarcane at the start of the harvest did not affect the juice clarifi cation and resulted in VHP sugar of a quality similar to that of the early maturation variety.

O emprego de okara no processamento de hambúrger de frango fermentado com Lactobacillus acidophilus CRL 1014

Okara is a residue of production process of soy milk, wich has a considered nutritional value for containing proteins, lipids and fi bers in signifi cant amount, besides bioactive compounds, such as isofl avone. Despite these qualities, the great amount of okara produced annually in Brazil and in other countries generates a problem of disposal waste and it has served only for animal food products. Such situation can be changed by studies, that demonstrate the viability of okara’s utilization in human nourishment. Thus, the purpose of this research was to develop a fermented hamburger with a probiotic bacteria, based on chicken meat and okara fl our. Five formulations were processed: F1-100% of chicken meat, unfermented and containing curing salts, F2-100% of chicken meat, fermented with L. acidophilus, F3 - 90% of chicken meat and 10% of okara meal, fermented with L. acidophilus, F4 - 70% of chicken meat and 30% of okara meal, fermented with L. acidophilus; F5 - 50% of chicken meat and 50% of okara meal, fermented with L. acidophilus. All formulations were evaluated for the viability of the probiotic culture, determination of cooking yield and shrinkage percentage, pH and sensory characteristics. The results have demonstrated that it is possible to elaborate a chicken hamburger, fermented with Lactobacillus acidophilus CRL 1014, with the addition of 10% okara fl our.
