Análise de sujidades e matérias estranhas em amostras de farinha de trigo tipo 1 comercializadas em Campo Mourão, Paraná

Abstract

Wheat has great global importance and is among the three most cultivated in the world. Wheat flour is the product with the milling process, being classified according to its characteristics, in Type 1, Type 2 and Integral. The nutritional and technological characteristics of wheat flour are influenced by different conditions, which may be different when grown and transported to the product. Faced with these factors, wheat flour may become contaminated due to infestation of wheat grains by field pests and even to its storage environment. In this sense, it is necessary to use good practices to ensure the quality of the product for distribution and commercialization, since a series of hazards are associated with incorrect processing and handling practices. Therefore, surveillance agencies are fundamental in the prevention and control of food-borne diseases, the National Agency of Sanitary Surveillance (ANVISA), establishes a tolerance limit for evaluation of macroscopic and microscopic foreign matter in foods, these being 75 fragments of insects indicative of failure of good practices in 50 g of wheat flour. The present work sought to collect, analyze and verify the quality of 12 samples of wheat flour type 1 commercialized in the city of Campo Mourão - PR, in order to verify its suitability, in line with current legislation, for human consumption. Based on the method of the Association of Official of Analytical Chemists International (AOAC). All 12 analyzed samples were within the limits established by ANVISA, however, it is important to stress the use and correct application of good manufacturing practices.
