ANÁLISES DE MATÉRIAS ESTRANHAS E MICROBIOLÓGICAS DE CHÁS INDUSTRIALIZADOS COMERCIALIZADOS EM POUSO ALEGRE MG / ANALYSIS OF EXTRANEOUS MATERIALS AND MICROBIOLOGICAL FROM INDUSTRIALIZED TEAS MARKETED IN POUSO ALEGRE MG

O objetivo deste estudo foi de avaliar as condições higiênico-sanitárias de quatro marcas de chás industrializados comercializados na cidade de Pouso Alegre ­ MG utilizando parâmetros de presença de matérias estranhas e análises microbiológicas. Foram coletadas no período de setembro a outubro de 2017, amostras de chás de camomila, erva-doce, hortelã e chá misto que contém em sua formulação essas mesmas ervas. Foram utilizados os métodos da Association of Official Analytical Chemists International (AOAC) de acordo com a RDC n°14 para capturar as sujidades leves e nas análises microbiológicas, foram utilizados métodos da International Organization for Standardization (ISO) de acordo com a RDC n° 12 para avaliar coliformes totais e termotolerantes, fungos e Salmonella spp. Nas pesquisas de matérias estranhas somente três marcas de camomila foram aprovadas, estando o restante dos chás em desacordo com a legislação vigente por estarem acima do limite de tolerância aceitável. Na avaliação de coliformes e Salmonella sp. todas as amostras foram aprovadas porém, houve um crescimento considerável de fungos filamentosos nestas amostras. Os estudos apontam grandes falhas nas boas praticas de fabricação, por se tratarem de produtos industrializados que contam com processos de limpeza e controle de qualidade para certificarem alimentos livres de risco a saúde dos consumidores. A pesquisa sugere uma revisão da resolução vigente para implantar a análise de presença de fungos

The aim of this study was to evaluate the hygienic-sanitary conditions of four brands of industrialized teas marketed in the city of Pouso Alegre ­ MG using parameters of presence of foreign matter and microbiological analyzes. Were collected in the period from September to October 2017, samples of chamomile teas, fennel, mint and mixed tea that contains in its formulation these same herbs. Were used the methods of the International Association of Analytical Chemists (AOAC) according to RDC n° 14 to capture light dirt and in the microbiological analyzes, were used the methods of the International Organization for Standardization (ISO) according to RDC nº 12 to evaluate total and thermotolerant coliforms, fungi and Salmonella spp. In the research of extraneous materials, only three brands of chamomile were approved, the rest of the teas being in disagreement with the current legislation because they are above the acceptable tolerance limit. In the evaluation of coliforms and Salmonella sp. all samples were approved, however, there was a considerable growth of filamentous fungi in these samples. The studies point out major flaws in good manufacturing practices, as they are industrialized products that rely on cleaning and quality control processes to certify foods that are free from risks to the health of consumers. The research suggests a revision of the current resolution to implement the analysis of the presence of fungi

Monitoring the extraneous matters in pulps of tomato, guava, mango and strawberry marketed during the seasons of the year

Fruit-derived products sold in Brazil and for exportation are required to comply with the quality and safety standards. These products and, among them, the fruit pulps may contain extraneous materials due to the inappropriate conditions or practices during their production, storage and distribution, including filth, decomposed material and miscellaneous materials. This study aimed at evaluating the sanitary conditions(regarding to extraneous materials) of fruit pulps sold in the Great São Paulo, during the four seasons of 2010. This investigation analyzed 115 tomato pulp, 93 guava pulp, 99 strawberry pulp and 89 mango pulp by means of the techniques described in the AOAC, 18th, 2005, Chapter 16 - Extraneous Materials: Isolation. Insect fragments were the most frequent filth category detected in the pulps (in 93 % of guava and strawberry, 77 % of tomato and 48 % of mango samples), followed by the rodent hair (in 24 % of tomato, in 3 % of guava, in 1 % of strawberry and in 0.5 % of mango samples). The occurrence of miteswas mostly frequent in strawberry samples (33 %). This study indicated that the majority of the analyzed pulps showed satisfactory sanitary conditions, evidencing that the Good Manufacturing Practices was adopted by the productive sector...
