A comprehensive evaluation method for goose meat quality

Abstract

The invention relates to a method for comprehensive evaluation of goose meat quality. The steps of the method are: measure 6 indexes such as pH, protein content, fat content, water content, collagen protein content and cholesterol content of goose meat, and establish a principal component comprehensive evaluation model (Y=0.237zx1+0.130zx2-0.410zx3 +0.352zx4+0.388zx5+0.211zx6), where: zx1, zx2, zx3, zx4, zx5, zx6 represent the standardized goose pectoralis major muscle pH, protein content, fat content, water content, collagen protein content and cholesterol content Measured value; respectively calculate the comprehensive score of meat and goose meat quality to be tested, and sort according to the comprehensive score to determine the quality of goose meat. In the present invention, the contribution rates of the first two principal components are 62.32% and 30.17% respectively; the cumulative contribution rate reaches 92.49%, which can reflect the comprehensive level of meat quality to the greatest extent, enhance the effectiveness of the evaluation function distinction, and thus improve the accuracy of evaluation. Accuracy, has a good application prospect.

Description

technical field [0001] The invention relates to the technical field of poultry breeding, in particular to a method for comprehensive evaluation of goose meat quality. Background technique [0002] At present, many scholars at home and abroad usually use the tasting method to identify the meat quality of goose, but this method has a lot of subjectivity. In the objective measurement and evaluation method, it is only limited to the judgment and comparison of individual traits such as the chemical composition and physical indicators of the muscle. As far as a certain meat goose is concerned, one or several meat quality traits are often better, while other traits are poor, and there are often contradictory results between unit traits, so it is difficult to evaluate different breeds or different feeding methods. Evaluation of goose meat quality. At the same time, as meat quality is a comprehensive trait, it is difficult to scientifically determine the weight of each unit trait, ...

As far as a certain meat goose is concerned, one or several meat quality traits are often better, while other traits are poor, and there are often contradictory results between unit traits, so it is difficult to evaluate different breeds or different feeding methods. Goose Meat Quality Evaluation

At the same time, as meat quality is a comprehensive trait, it is difficult to scientifically determine the weight of each unit trait, and no comprehensive evaluation method for goose meat quality has been established.
