Method for rating of raw milk quality

Abstract

The invention provides a method for rating of raw milk quality. The method for rating of raw milk quality comprises the following steps of determining fat content, protein content, fungimycin content, total bacterial colony content and impurity content of a raw milk sample, respectively carrying out normalization treatment on data of the fat content, the protein content, the fungimycin content, the total bacterial colony content and the impurity content through the existing neural network normalization method, drawing a radar map according to the treated data, carrying out cluster analysis of the treated data by the radar map, transforming the radar map into a pyramid form by a topological transformation method of mathematics, carrying out inverted normalization treatment on data of the pyramid form, and carrying out grading of the data of the pyramid form according to raw milk quality information needed actually so that rating of raw milk quality is realized. The method for rating of raw milk quality can realize concise and clear rating of raw milk quality by a three dimensional image, is reasonable and feasible, has a wide application scope and a high practical value, and is conducive to objective evaluation and selection given by consumers, enterprises and milk farmers on quality of raw milk and congeneric related foods according to vital interests.

Description

technical field [0001] The invention relates to a method for grading raw milk quality, which belongs to the field of food safety and quality. Background technique [0002] The safety of raw milk in the field of food safety is: In 2010, the state promulgated 66 national food safety standards such as "Raw Milk" (GB19301-2010), which stipulated that the total number of colonies in raw milk should be 2 million CFU / ml, and the protein content of raw milk should be greater than 2.8 %, the fat content is greater than 3.1%, pollutant limits, mycotoxin limits, pesticide residue limits, and veterinary drug residue limits. Improve raw milk quality. [0003] Abroad, the International Dairy Federation (IDF) national raw milk rating standards, including Canada, the Czech Republic, New Zealand, the United States, the United Kingdom, and Japan, only grade the milk components, the number of live bacteria and the degree of impurities. All are valued and the higher the ingredients, the highe...

AI Technical Summary

Problems solved by technology

At present, whether domestic or foreign, it is limited to use a few key factors as the rating standard to reflect the quality information of raw milk in a flat, static, and one-sided model, but none of them can reflect the quality of raw milk in a timely, concise and effective manner.
