Abstract

Rice is one of the main energy supply products of a contemporary society, and it is therefore essential to study processes that come from the perspective of obtaining a product with functional and organoleptic properties suitable for human consumption. The objective of the present work was to analyze the effects of the temperature and feed load variables of the stream bed in the drying process of the parboiled rice, evaluating the physical and chemical characteristics of the parboiled rice. The particle diameter, sphericity and specific mass of the parboiled rice particles were determined by the parboiled rice particles, with values of 2.27 mm, 0.83 and 1.20 g/cm³, respectively. The conditions for the feedstock and temperature parameters defined in the drying of the parboiled rice were 1000 g and temperature of 40°C and 60°C in a time of 45 minutes. As a result for samples 1B and 2B, it was possible to obtain the following moisture values of 15.7% and 15.1%, yield of 76.56% and 75.37%, water activity of 0,678 and 0,670 respectively. Samples 1B and 2B showed darker staining than control sample of white rice, according to CIELAB color analysis system.
