Rice is the most important staple food in our life. After Yuan Longping's academician cultivated hybrid rice and solved the problem of rice production, modern people's focus on rice gradually turned to quality. Although the quality of rice in China is still far from that of developed agricultural countries such as Japan, in recent years, more investment has been invested in the cultivation of varieties, and a large number of testing instruments such as rice appearance quality inspection systems have been applied. Conduct test analysis and use data as a benchmark to promote rice quality. The following mainly introduces the appearance quality of rice evaluation.
The evaluation of rice quality is mainly based on the appearance, cooking, consumption and nutrition. The appearance quality of rice refers to the physical properties of brown rice grains or polished rice grains. Specifically, it refers to the length, width, shape and appearance of rice. The indicators have indicators such as 1000-grain weight, aspect ratio, transparency, chalkiness, and chalkiness. High-quality rice has strict regulations on the appearance quality. For example, the aspect ratio of high-quality japonica rice is not less than 2.8, and the white grain rate and chalkiness are not higher than the specified indexes. The use of rice appearance quality inspection system can quickly and accurately determine the appearance quality of rice, which is a widely used detection method for detecting the appearance quality of rice.
In fact, comprehensive assessment of rice quality, then often need to assess a number of indicators of rice, including rice appearance quality indicators, but also rice taste quality indicators, nutrition and health quality indicators. It is the most scientific and reliable way to use the instrument such as rice appearance quality inspection system for evaluation and analysis. For example, in the process of rice quality identification, Japan is equipped with quality testing instruments to test the stages of rice drying, storage, and rice milling; whiteness meter is used to measure the processing precision of whiteness; in the rice milling plant, quality management system and cooking are set up. In the rice laboratory; the taste identification value is also calculated through the results of the three kinds of testing instruments through the taste appraisal group; finally, the rice food taste meter, the hardness/viscometer, and the result of the fresh measuring instrument are used to judge the best use of the rice.
