Method for selecting special rice for rice dumplings

Abstract

The invention provides a set of perfect rice dumpling quality evaluation system, which comprises a method for selecting special rice for rice dumplings and a method for screening core indexes. Selection of the special rice for the glutinous rice balls comprises selection of glutinous rice raw materials, determination of main components of glutinous rice, determination of gelatinization characteristics of the glutinous rice, preparation of quick-frozen glutinous rice balls, cooking treatment of the quick-frozen glutinous rice balls and determination of texture of the glutinous rice balls. The core index screening method of the special rice for the rice dumplings comprises the following steps: extracting principal components of rice dumpling quality, calculating comprehensive scores of the rice dumpling quality, performing clustering analysis on the comprehensive scores of the rice dumplings and formulating comprehensive evaluation standards of the rice dumplings. The method solves the problem of uneven varieties and qualities of raw material glutinous rice used by the glutinous rice balls, defines a glutinous rice ball special-purpose glutinous rice quality evaluation system, and provides a unified screening method for glutinous rice ball high-quality special-purpose rice. According to the system, core indexes influencing the quality of the glutinous rice balls are exactly provided and are used as references for evaluating the quality of the glutinous rice balls, and a theoretical basis is provided for ensuring the production efficiency and the eating quality of glutinous rice ball products.

Description

technical field [0001] The invention belongs to the technical processing field of rice products, and more specifically relates to a screening method for special rice for glutinous rice balls. Background technique [0002] Tangyuan is a traditional glutinous rice product made from glutinous rice by crushing, adding water to make dough, forming and quick-freezing. With the advancement of modern quick-freezing technology, the rice dumpling food industry has developed rapidly. In the process of large-scale industrial production of quick-frozen glutinous rice balls, the glutinous rice dough often has problems such as cracking in varying degrees, shape collapse, and intolerance to cooking, which seriously affects the quality of quick-frozen glutinous rice balls, and there are many varieties of glutinous rice in my country. There are significant differences in characteristics, which also lead to uneven quality of glutinous rice balls, which is not conducive to the development of gl...

AI Technical Summary

Problems solved by technology

The above studies have not determined the range of key indicators of glutinous rice raw materials, and it is difficult to fully reflect the influence of the characteristics of glutinous rice raw materials on the quality of glutinous rice balls

This research uses the method of principal component analysis to reduce the collinearity of the quality index of glutinous rice balls, transforms more original variables into several principal components that can summarize the entire sample, and calculates the comprehensive evaluation value through data analysis methods. The method has been applied to the quality evaluation of beef tenderness, cherry fruit and potato vermicelli, but rarely used in the quality evaluation of glutinous rice balls
