Diagnóstico higiênico-sanitário das casas de farinha da Microrregião de Imperatriz, MA

Abstract

Physical, chemical, physico-chemical, microbiological and microscopic analyzes were performed for cassava flour of two types: dry group and water group and the conditions of processing units were checked. Based on these results, a manual was prepared to improve the processing conditions and hence product quality based on the law. This study work was conducted in 14 primary processing of cassava flour distributed in the cities of Imperatriz, João Lisboa, Senador La Rocque and Buritirana, located at Microregion Imperatriz, MA. The instruments used for data collection targeted to producers of flour were: a) a questionnaire addressing issues relating to the production and marketing of cassava flour in Microregion Imperatriz b) a checklist called "Sheet Inspection facilities in area Food "(FIEAA), used as a model by the Safe Food Program, industry segment (PAS-INDUSTRY). For the sellers, we designed a structured questionnaire with closed and open questions. Data analysis revealed deficiency in 100% of the flour mills in all observed requirements, in which corrective measures in the short and medium time is requeired to ensure product quality and consumer health. To evaluate the quality of cassava flour, 20 samples obtained from fairs city of Empress and 3 collections in flour mills of Microregion Imperatriz were evaluated. Physicals, chemicals and physic-chemicals results showed that all samples are in accordance with standards established by the Normative Instruction (IN) 52/2011 of the Ministry of Agriculture, Livestock and Supply (MAPA), in respect to moisture and ash content. Regarding to the fiber content, 3 samples were above of the maximum tolerance (2,3%). For starch content, 10 samples were below of the minimum tolerance percentage (80%). For acidity, 6 samples of dry group showed high acidity and 2 had low acidity. All samples of the water group showed low acidity. Regarding to the particle size, the samples of the water group were classified as coarse, while dry group flour presented media (38%) and coarse (62%). According to the RDC Resolution No. 12/2001 of the National Health Surveillance Agency (ANVISA), the microbiological quality of the samples showed the hygienic and sanitary conditions of processing units. Regarding to the microscopic analyzes, the samples showed a high degree of contamination: 100% of samples presented of dirt and black color, plastic fiber fragments, fragments of insects 21,7%, 13,0% for, 8,7% grains of sand, and 13,0% had twig, bird feather rachis or tangle of cotton yarn. According to IN 52/2011, all samples should be classified as disqualified, being considered non-adequate for human consumption.
