Methods of evaluating the quality of rice grain and its processing products in foreign research

The article analyzes modern methods of quality control of rice grain and products of its processing developed by foreign scientists. The analysis of available foreign scientific publications has shown that solving the problem of the duration and accuracy of laboratory tests of the component composition of grain mass and characteristics of rice quality is an urgent international task. Computer vision systems which are used to characterize properties of raw materials, assess its quality and the quality of finished products are promising in terms of solving this problem. However, the known methods for assessing the quality of rice grain and products of its processing, proposed by foreign scientists, have a major drawback, namely, duration of the method implementation, as a result of which there is no possibility of operative quality control of rice grain, which does not allow regulating and stabilizing treatment regimes for some stages of technological process.
