Qualidade do arroz beneficiado na região fronteira oeste do Rio Grande do Sul

Abstract

Rice (Oriza sativa) is a cereal produced and consumed on five continents. Brazil produces an average of 10.6 million tons, with Rio Grande do Sul, the state with the highest production. It represents a good source of energy due to the high concentration of starch, vitamins, proteins and minerals. The quality of the rice grain, directly reflects on the price and acceptance by consumers, thus, the present work aims to analyze the quality of the processed rice on the west border of Rio Grande do Sul, using 11 (eleven) samples of polished processed rice, type 1, of the long-thin class, with 4 (four) repetitions, using a completely randomized experimental design. For the determination of the type, the defects were quantified, being them, moldy, burnt, stained and chopped grains, yellow, plastered, green and streaked. In the laboratory, the procedures were performed by sensory analysis to detect disqualifying factors (odors, live insects, treated seeds, etc.), with none of these proceeding, the sample was quarantined up to a working sub-sample of no minimum (100 g) and another of approximately 250 g to determine the moisture content; with the sample of work, it was separated whole, broken and broken; followed by the analysis of defects (separation and measurement) for the classification in Type. The current MAPA legislation imposes the tolerance limits for the classification of rice in Brazil, being used as a template for comparison with the results that were obtained. At the end of this work, it was found that there was no significant difference in the comparison of the results obtained and the tolerance limits established by the legislation in force in Brazil, guaranteeing to the final consumer, food and nutritional security. Thus, it was concluded that the regionalization of production does not influence the magnitude of occurrence of the defects assessed.
