RESUMOO setor de produção de leite no Brasil, apresenta problemas de qualidade e por isso perde em competitividade. Assim, o Ministério da Agricultura, Pecuária e Abastecimento, publicou em 30 de dezembro de 2011 a Instrução Normativa 62 (IN 62), na qual fixa valores para os parâmetros físico-químicos, Contagem Bacteriana Total (CBT), Contagem Células Somáticas (CCS), além de propor um controle de resíduos inibidores e antibióticos no leite. Em virtude da implantação dessa normativa, objetivou-se com este trabalho avaliar a qualidade do leite cru produzido em propriedades na região do semiárido mineiro bem como o perfil das instalações e dos produtores de leite. Foram coletadas 92 amostras de leite cru e encaminhadas para análise na clínica do leite e no laboratório da indústria. Foram realizadas análises físico-químicas, contagem de células somáticas, contagem bacteriana total e teste de resíduo de antibióticos. Os dados referentes ao perfil dos produtores, às condições sanitárias e à tipologia das edificações foram obtidos por meio de questionários e, posteriormente, foram apresentados em porcentagem. Os valores das propriedades físico-químicas, ao serem submetidos ao teste qui-quadrado, revelaram concordância com a legislação vigente. Os parâmetros CCS, CBT e índice crioscópico apresentaram valores acima dos permitidos pela legislação. A falta de refrigeração do leite foi o parâmetro que apresentou maior descumprimento com relação à IN 62. PALAVRAS-CHAVE:higiene, Instrução Normativa, produção. ABSTRACTThe Brazilian dairy industry has trouble with milk quality and, therefore, it loses competitiveness. Thus, the Ministry of Agriculture, Livestock and Supply, published on December 30, 2011, the Normative Instruction 62, in which fixed values for the physical and chemical parameters, somatic cell counts (SCC), composition and total bacterial counts (TBC) as well proposing controlling inhibitors and antibiotic residues in milk. Due to the implementation of this rule, the aim of this work was to evaluate the quality of raw milk produced on the properties in the semiarid region of Minas Gerais state as well as the profile of the installations and dairy farmers. We collected 92 samples of raw milk and sent them for analysis in milk clinical and industry laboratory. Physical and chemical analysis, somatic cell count, total bacterial count and antibiotic residue test were performed. The data relating to the profile of producers, sanitary conditions and the types of buildings were obtained by means of questionnaires and the data was presented as a percentage. The values of the physical-chemical properties were submitted to the chi-square test and it was found that they are consistent with current legislation. The SCC parameters, TBC and cryoscopic index showed values above those allowed by law. The lack of milk cooling was the parameter with the highest non-compliance with respect to IN 62.
This study aimed to evaluate the influence of different levels of irrigation on the quality parameters involved in the dried-bananas production from 3 different cultivars. The experimental design was a completely randomized factorial 3 x 3, with three genotypes of bananas (Prata-Anã, FHIA-18 and BRS Platina) produced in the semi-arid region of Minas Gerais.) and three irrigation levels (50, 75 and 100% of crop evapotranspiration - ETC), with three replications. For the processing purpose, the fruits were selected at the maturity stage 6. Then they sanitized in hypochlorite of sodium solution at 100 mg L-1, peeled and dehydrated through the drying convective method with hot air, in dryer with forced air, in dryer with forced air circulation at 65ºC for 24 hours. The dried bananas were evaluated according to the following physical and chemical aspects: moisture, length, diameter, firmness, color (brightness, chroma and ºHue), soluble solids and titratable acidity, and sensory characteristics: purchase intention and acceptance. The humidity, length, diameter, firmness, color and acidity of dried bananas were influenced by the different studied irrigation levels. In the sensory evaluation, the best result regarding appearance, color, texture and flavor requirements was observed in banana processed from 'Prata-Anã' irrigated with the total level of water (100%). The dried banana processed from 'BRS Platina' was the least accepted in the sensory tests.
Neste trabalho avaliou-se a encapsulação da polpa de umbu porco-cristalização com sacarose, determinando-se o efeito do pH dapolpa adicionada sobre as propriedades físico-químicas do suco cocristalizadoe sua estabilidade durante o armazenamento. O sucoco-cristalizado apresentou alta solubilidade e baixa pegajosidade,situando-se na faixa em que se encontra a maioria dos pósalimentícios. Verifi cou-se que, de maneira geral, o suco de umbuco-cristalizado apresentou características físico-químicas queconferem boa estabilidade ao produto.
