[0040] (1) Color quality classification of the longest pork back muscle and its correlation with temperature and pH

[0041] 1 Materials and methods

[0042] 1.1 Materials

[0043] 500 pig carcasses (2003, March-2003, July) were randomly selected from the existing production line of Yurun Group Donghai Furun Meat Processing Factory Co., Ltd. (daily slaughtering 1500-2000 heads), and the hair weight of these pigs was 90-100kg Between 5 and 6 months of age, without considering the background of pre-mortem factors such as breed, sex, and genotype. But the pre-slaughter and production process and process conditions are the same.

[0044] Portable pH meter (HANNA-HI9025microcomputure, produced in Portugal); Portable colorimeter (MinoltaCR200, D 65 Light source, caliber Φ=8mm, made in Japan); standard color guide (grade 6, made in the United States).

[0045] 1.2 Data collection

[0046] The pig carcasses were cut in half on the slaughtering production line and before entering th...

Abstract

A method based on the computer visualization technique for classifying the quality of pork by its color includes such steps as preparing the standard color map according to the color space recommended by CIE, taking the pork specimen, and comparing it with said standard color map to determine its quality.

Description

1. Technical field [0001] The invention relates to a method for grading pork color quality grades, which belongs to the application of computer vision in the classification of agricultural products, and is specially used for the division method of pork color quality grades. 2. Background technology [0002] With the development of my country's market economy and its entry into the WTO, in order to standardize the market and meet international standards, it is of great significance to classify meat to realize the quality division of carcass or different parts of carcass, so as to achieve high quality and good price. Through the research on the characteristics of meat color, how to effectively realize the objective, accurate, fast or non-destructive detection of meat color and its changes is of great significance to the automatic grading of meat. With the development of sensory evaluation science and the development of advanced instruments and equipment, foreign research on t...
