Flour is a kind of food material that people like very much. It is used very much in our country. With the improvement of people’s living standards, people not only require good flour quality and good taste, but also require good whiteness of flour. Although the use of additives can increase the whiteness of flour, it can also cause the quality of flour to decline, as well as harm. Health and other issues, so to improve the whiteness of flour through breeding, is an ideal way to enhance the whiteness of flour.
Nowadays, in order to adapt to the frequent determination of the whiteness of flour, flour production enterprises widely use the whiteness meter, and the application shows that the whiteness measurement meter has the advantages of high stability, high precision and high efficiency. Therefore, the use of whiteness meter to determine the whiteness of flour can help to optimize the high whiteness of wheat varieties, so as to provide reference for wheat breeding.
Studies have shown that flour whiteness is a quantitative trait controlled by multiple genes and has a high heritability. The flour mainly comes from the wheat endosperm. The pigment, polyphenol oxidase and protein in the endosperm are the main internal factors that affect the whiteness of the flour. Flour whiteness or color is mainly controlled by genetics. There is a significant difference in flour whiteness between varieties. Breeding can effectively change the surface pinkness, reduce the activity of polyphenol oxidase, and increase the whiteness of flour.
Therefore, since the determination of the genetic factors related to pigments, polyphenol oxidase, and protein are all important factors that affect the whiteness of wheat flour, the determination of the whiteness tester can help determine wheat varieties with good flour whiteness. In order to improve wheat varieties through breeding and biotechnology, the whiteness of flour is increased and the added value of flour is increased.
Application of Whiteness Tester in Wheat Breeding
As we all know, flour is usually wheat flour, but it is also made from wheat. In recent years, people used the whiteness meter to measure and analyze and found that the whiteness of flour is closely related to the variety of wheat, so in order to improve The natural whiteness of flour, people hope to use the whiteness meter to participate in the improvement of wheat varieties, in order to improve the whiteness of the flour.
