Method for screening rice suitable for making rice flour and method for predicting quality of rice flour

Abstract

The invention discloses a method for screening rice suitable for making rice flour. The method comprises the following steps: obtaining the component content of the rice; comparing the component content with a standard value; and determining whether the rice is suitable for making rice noodles or not according to a comparison result. The invention further discloses a method for predicting the cooking quality of the rice flour. The method comprises the following steps: acquiring an RVA characteristic value and a Mixolab characteristic value of the rice flour; and predicting the cooking qualityof the rice flour prepared from the rice flour according to the RVA characteristic value and Mixolab characteristic value of the rice flour. The rice flour prepared from the rice raw materials screened by the method disclosed by the invention has relatively good cooking characteristics, namely low breaking rate, proper viscoelasticity, fineness, softness and chewiness, and relatively good taste and appearance. By means of the prediction method, the quality indexes of the prepared rice flour can be accurately predicted according to the properties of the rice flour.

Description

technical field [0001] The invention belongs to the technical field of food science and engineering, and mainly relates to a method for screening rice suitable for making rice noodles and a method for predicting the cooking quality of rice noodles. Background technique [0002] Rice noodles (threads) usually use rice as the main raw material, and are made of thin strips or wide flat rice through complex processing procedures such as washing, soaking rice, semi-dry crushing or water grinding, heating and gelatinization, extrusion or cutting. products. my country is a big rice-growing country. According to incomplete statistics, my country's rice output in 2018 reached 202.7 million tons, and about 60% of the people in the country regard rice as their staple food. One of the most common deep processing methods is to make rice noodles, except that it is directly used for sales to make rice and store. [0003] Rice can be divided into indica rice, japonica rice and glutinous r...

AI Technical Summary

Problems solved by technology

Therefore, the difference in rice varieties also leads to the uneven quality of the rice noodles produced, which is not conducive to the development of the rice noodle industry.

However, there is no relevant standard for special rice for rice noodles at present, and there is no document publicly reporting what kind of rice is suitable for making rice noodles
