Abstract

This research aimed to classify the polished rice (Orysa sativa L.) used in restaurants in Belo Horizonte-MG, Brazil. Eight restaurants, aimed at offering healthy meals in the different administrative regions of Belo Horizonte-MG, Brazil, took part in this study. The moisture content and the presence of foreign matter and impurities, broken grains and grits, mouldy and sour grains, chopped or pecked grains, chalky and immature grains, yellow and streaked grains, were determined. The class and type were determined according to current legislation, and the cooking time, volume, cooking test, increase in volume, yield and yield factor were analysed. The results showed that 37.5% (n=3) of the restaurants used Type 2 rice but this did not significantly change the cooking tests. In conclusion, no direct relation existed between the type of rice and the quality and yield of the end product.
