Construction method and application of chicken quality fatty acid evaluation model

Abstract

The invention discloses a construction method of a chicken fatty acid evaluation model. The construction method comprises the following steps: S1, detecting chicken fatty acid compositions and relative contents under different conditions; S2, performing Pearson correlation verification on the fatty acids obtained in the step S1, and if significant correlation does not exist between the fatty acids, using the fatty acids to construct a chicken quality fatty acid evaluation model; if the fatty acids have significant correlation, further determining a core fatty acid through OPLS-DA discriminantanalysis of a supervised classification model; and S3, carrying out weight distribution of the core fatty acid through an analytic hierarchy process, and acquiring a fatty acid evaluation model used for obtaining the chicken quality, wherein the fatty acid evaluation model is that a comprehensive evaluation score of the fatty acid is equal to the weighted sum of all the core fatty acid scores. Thequality of the chicken and the nutritional value which can be reflected by the chicken can be evaluated by detecting the fatty acid of the chicken, proper breeding conditions can be conveniently obtained based on a fatty acid evaluation model, and the actual chicken quality and the nutritional value brought by the actual chicken quality are improved.

Description

technical field [0001] The invention relates to the field of meat quality evaluation, and more specifically, to a construction method and application of a chicken meat quality fatty acid evaluation model. Background technique [0002] The quality of edible chicken meat is affected by various conditions, including age, feeding mode, gender, etc. The quality of chicken meat obtained based on different culture conditions is also significantly different. On this basis, obtaining the quality of chicken is very important to the development of the chicken market. Considering from the farming side, farmers can further improve various conditions on the basis of obtaining the quality of chicken, so as to cultivate and obtain modern chicken meat. Chicken with the actual quality demand of the population; from the perspective of consumption and supervision, obtaining the quality of chicken will help to evaluate the chicken on the market in a timely manner, so as to screen chicken that me...

AI Technical Summary

Problems solved by technology

[0003] At present, the methods for obtaining the quality of chicken are mostly considered from the perspective of sensory or physical and chemical characteristics, which often cannot reflect the quality evaluation of chicken nutrition, and one of the purposes of eating chicken is to obtain the nutrients of chicken. Therefore, the prior art Chicken quality evaluation may often fail to truly obtain the quality of chicken meat that meets eating needs
