The development track of wheat hardness classification
The development track of wheat hardness classification The accurate determination and classification of wheat kernel hardness is the basis of quality analysis. The wheat industry in developed countries in the world is classified according to the color of wheat grain, winter and spring, hardness, protein content and gluten quality. Before the 1980s, Chinese commercial wheat was mainly divided into 6 categories (GB 1351-86) according to the appearance of grain color and horniness rate (differentiated between soft and hard); the current national standard (GB 1350-1999) promulgated in the late 1990s will be Wheat is divided into 9 categories based on appearance color, winter and spring and keratinocytes. This classification is not in line with international standards, and because there is no obvious difference in the quality of winter wheat and spring wheat in China, it is of little significance to consider winter and spring sex issues in quality classification. In practice, these standards are not perfect. Of course, due to the limitations of measurement standards and instruments, only the kernel keratin rate can be used to roughly determine the hardness of wheat in the national standards and during grain purchase and processing. In view of the fact that grain hardness is an important criterion in international wheat classification, keratinocyte rate evaluation has certain limitations. Grain and breeding departments in our country often regard keratinocyte rates as hardness, so we need to learn from and adopt more objective evaluation systems or explore further. New methods and development of new measuring instruments. Lin Zuojun and others proposed the establishment of hardness standards and added indicators of hardness to national standards. Therefore, the innovative wheat hardness index determination method and the standardization of the wheat hardness tester have become an urgent task. During the development process, the "National Institute of Standards for Wheat Hardness - Hardness Index" National Standards Group sent the wheat hardness meter to the relevant agricultural inspection departments, milling companies, and wheat storage and storage companies. The results show that the use of the hardness index method to determine the hardness of wheat and distinguish wheat varieties, with high resolution, simple measurement, human error is small, and good reproducibility, the average standard deviation is 0. 23 ~ 0. 46 . Therefore, many testing organizations now use the wheat hardness tester to determine the hardness of wheat.
Electric Kettle
Electric Kettle are made by food grand stainless steel and
Polypropylene. It helps you to have a 1.8L bottle of boiled water in 5 minutes.
Type 201 Stainless stell is the main material for the electric kettle housing.
sometimes called a tea kettle or teakettle, is a type of pot, typically metal,
