_________________________________________________________________________________________________________________Resumo: O mercado de embutidos tem apresentado grande expansão e alta competitividade na última década, uma vez que o consumo de produtos cárneos como salsichas, linguiças e mortadelas tem se tornado cada vez mais presente no hábito alimentar da população brasileira. Sais de cura, como nitrato e nitrito de sódio e de potássio, são largamente utilizados como aditivos alimentares no processamento de produtos cárneos e têm a finalidade de conservar, intensificar ou modificar as propriedades sensoriais dos alimentos. Este trabalho teve como objetivo determinar o teor de nitrito em embutidos comercializados na cidade de Avaré -SP e região através do método espectrofotométrico. Os embutidos utilizados na pesquisa foram mortadelas, salsichas e linguiças frescais. Foi analisado um total de 270 amostras de embutidos de três diferentes marcas cada. A determinação do íon nitrito foi realizada através do método espectrofotométrico a 540 nm. A presença de nitrito estava em todas as amostras dos produtos cárneos analisados, cujas concentrações médias variaram de 29,25 ppm a 249,80 ppm. Entre os embutidos, a linguiça das marcas A e C apresentaram um teor de nitrito superior ao permitido na legislação brasileira (máximo 150 ppm). Conclui que medidas de controle de produção de linguiça frescal e educação sanitária poderiam ser aplicadas com mais rigor em indústrias e estabelecimentos comerciais a fim de se garantir produtos de maior qualidade e seguros quanto ao teor de nitrito em sua composição.

Abstract:The cured meat products have shown great expansion and high competitiveness in the last decade, since the consumption of meat products such as sausages, fresh sausages and mortadellas has become increasingly present in the food habits of the Brazilian population. Curing salts, such as sodium and potassium nitrate and nitrite, are widely used as food additives in the processing of meat products and have the purpose of preserving, enhancing or modifying the sensory properties of foods. The objective of this work was to determine the content of nitrite in cured meat products in the city of Avaré -SP and region using the spectrophotometric method. The cured meat products used in the research were mortadellas, sausages and fresh sausages. We analyzed a total of 270 samples of sausages market from three different brands each. The determination of the nitrite ion was performed by the spectrophotometric method at 540 nm. The presence of nitrite was present in all samples of the meat products analyzed, whose average concentrations ranged from 29.25 ppm to 249.80 ppm. Among the cured meat products, the sausage brands A and C presented nitrite content higher than allowed in Brazilian legislation (maximum 150 ppm). It concludes that measures to control the production of fresh sausage and health Revista Brasileira de Higiene e Sanidade Animal Brazilian Jour...
25% of organic honeys and 27.3% of eucalyptus honeys were altered for the Fiehe reaction and humidity, respectively. 6.67% for the Lund test and 6.67% for diastase ferments were altered for orange honeys. The main conclusion is that transport and storage hindered the physico-chemical quality of the honeydew, eucalyptus and orange trees.
_______________________________________________________________________________________________________Resumo: O palmito é usado como alimento desde épocas remotas, sendo atualmente utilizado não só na culinária brasileira, como também na internacional. O presente trabalho teve como objetivo avaliar a qualidade da salmoura e do palmito em conserva do tipo açaí (Euterpe oleracea) comercializado na forma inteira ou em pedaços. Abstract: Palm heart is used as food from remote times, and is currently used not only in Brazilian cuisine, but also in international cuisine. The objective of this study was to evaluate the quality of canned brine and heart of açaí (Euterpe oleracea) type marketed in whole or in pieces. Samples were stored for 45 days at 4°C, at room temperature and at 37°C. A total of 360 samples of palm hearts were analyzed in integers (n = 180) and in pieces (n = 180). The physico-chemical tests were pH, acidity (% SAN) and osmolality (mOsM/kg). The microbiological assays were the total coliforms counts (35 o C), Clostridium sulphite reducer count and Escherichia coli counts. The results showed that whole and broken canned palm hearts are in accordance with Brazilian legislation. However, the pH value of the canned brine of preserved heart of palm preserved at 37 o C presented a value higher than 4.5. Based on our experiment, we conclude that the storage of the whole heart of palm at 37 o C changes the pH of the brine leaving the product in conditions for the growth of pathogenic microorganisms.
Resumo: O crescimento do consumo de iogurtes no país requer um produto de qualidade e seguro aos consumidores. O objetivo deste trabalho foi avaliar a qualidade físico-química e microbiológica de iogurte de coco e de morango comercializados na região de Botucatu, São Paulo, Brasil. Foram analisados trinta e três amostras de cada sabor de iogurte, em duplicata, totalizando sessenta e seis amostras. As análises físico-químicas foram a acidez total, pH e umidade. As análises microbiológicas foram coliformes a 35ºC, contagem de Escherichia coli, Salmonella spp., bolores e leveduras. Os valores de acidez, pH e umidade não apresentaram diferenças estatísticas significativas (p>0,05) entre os iogurtes. Não apresentaram conformidades microbiológicas no iogurte de morango para 5% para contagem de coliformes a 35 o C e 35% para contagem de bolores e leveduras. No iogurte de coco, as amostras não conformes foram de 7,7% para contagem de coliformes e 38,5% para contagem de bolores e leveduras. Ocorreu ausência de Salmonella spp. nas amostras. Concluímos que independentemente do sabor do iogurte o controle microbiológico da indústria lática, transporte e armazenamento devem ser intenso para assegurar um produto final de qualidade para o consumidor.Palavras-chave: Coco; Físico-Química; Iogurte; Qualidade; Microbiologia; Morango. Abstract:The growth of yogurt consumption in the country requires a quality and safe product to consumers. The objective of this work was to evaluate the physicalchemical and microbiological quality of coconut and strawberry yoghurt marketed in Botucatu, São Paulo, Brazil. Thirty-three samples of each yogurt flavor were analyzed, in duplicate, totaling sixty-six samples. The physicochemical analyzes were total acidity, pH and humidity. Microbiological analyzes were coliforms at 35ºC, counts of Escherichia coli, Salmonella spp., molds and yeasts. The values of acidity, pH and humidity did not present significant statistical differences (p>0.05) among yogurts. They did not present microbiological conformities in strawberry yogurt to 5% for counting of coliforms at 35 o C and 35% for counting of molds and yeasts. In coconut yogurt, non-conforming samples were 7.7% for coliforms counts and 38.5% for molds and yeasts counts. Absence of Salmonella spp. in the samples. We conclude that regardless of the taste of yogurt the microbiological control of the lactic, transport and storage industry must be intense to ensure a final quality product for the consumer.
