A method for identifying the quality of yellow-feather broiler chickens and white-feather broiler chickens

Abstract

The invention discloses an identification method of the meat quality of a yellow feather broiler and a white feather broiler. The identification method is respectively used for measuring the protein content, the fat content, the brightness value, the hardness value and the cooking loss ratio of a to-be-measured chicken sample. Measured numerical values are input into an identification equation to be calculated to obtain a Y value, if the Y value is less than or equal to 26.65, the to-be-measured chicken sample is determined to be the yellow feather broiler, and if the Y value is greater than or equal to 26.89, the to-be-measured chicken sample is determined to be the white feather broiler, wherein the identification equation is as follows: Y=(0.2127*the protein content)+(0.1196*the fat content)+(0.0522*the brightness value)+(0.3534*the hardness value)+(0.2620*the cooking loss ratio). The identification method has the advantages of simplicity, easiness in operation, high accuracy and practicability, and the like.

Description

technical field [0001] The invention relates to the field of identification of meat products, in particular to a method for identifying the quality of yellow-feather broiler chickens and white-feather broiler chickens. Background technique [0002] Chicken is one of the main meat varieties in China. It has the characteristics of high protein, low fat, low cholesterol and low calorie, and is widely welcomed by consumers. In my country, broiler chickens are mainly fast and large white-feather broilers represented by Avian and high-quality yellow-feather broilers represented by local breeds in our country. It has been reported in the literature that imported fast-growing large-scale broiler chickens grow fast and produce more, but their meat quality and flavor are poor. However, the meat quality and flavor of yellow-feathered broiler chickens in my country are better than white-feather broiler chickens, so there will be differences in market prices. However, because most of th...

It has been reported in the literature that imported fast-growing large-scale broiler chickens have fast growth and high output, but their meat quality and flavor are poor. However, the local breed of yellow-feathered broiler chickens in my country has better meat quality and flavor than white-feather broiler chickens, so there will be differences in market prices

However, because most of the sales in the market are sold as white striped chickens, it is difficult to visually distinguish them, resulting in losses for consumers.

[0003] At present, most of the identification methods for meat quality are the identification of PCR reaction primers, which need to extract sample DNA. The identification procedure is relatively cumbersome and the cost is high.
