Embodiment 1

[0040] Using the seven main meat quality indexes in this method to evaluate the meat quality of snow pheasant can obtain a more accurate and reliable evaluation. (See Table 3)

[0041] Table 3 The index values ​​of Xueshan yellow chicken breast muscle quality at different grades

[0042]

[0043] The MQI value for the quality of Snow Mountain Yellow Chicken is:

[0044] MQI=0.33*10+0.161*10+0.165*10+0.117*5+0.125*5+0.057*10+0.044*10=8.78 The MQI value of the meat quality of Snow Mountain Grass Chicken is: MQI=0.33*10+0.161*10 +0.165*5+0.117*10+0.125*5+0.057*10+0.044*10=8.54 By calculating the MQI value, it can be found that the quality of snow mountain yellow chicken is better than snow mountain grass chicken.

Abstract

The invention relates to the field of food science and animal husbandry, in particular to a comprehensive evaluation method for Xueshan chicken quality. The method includes: determining the following 7 meat quality evaluation indexes of a chicken sample, i.e. ATP, IMP, the pH value 1h after slaughter, water-holding capacity, shear force, flesh color and IMF, conversing the measured data average value of each meat quality index into an index value of corresponding grade, bringing the index values into a formula, calculating the proper selection index MQI value of meat quality traits, and determining the chicken quality according to the MQI value score. The method selects 7 main meat quality evaluation indexes, standardizes the determination method, and therefore can acquire more accurate and reliable experimental data; through correlation analysis of all the evaluation indexes, the interrelation among the indexes is determined, thus providing reference for establishment of a unified evaluation method and standard.

Description

technical field [0001] The invention relates to the fields of food science and animal husbandry, in particular to a method for comprehensive evaluation of the quality of snow mountain chicken. Background technique [0002] "Snow Mountain Chicken" is a high-quality chicken independently bred by Jiangsu Lihua Animal Husbandry Co., Ltd. that is suitable for the needs of the mid-to-high-end market. It has been approved by the National Livestock and Poultry Genetic Resources Committee and has become a national new breed (supporting line). Since its launch, it has been favored by consumers for its beautiful appearance, unique meat flavor, rich nutrition, no drug residues, and low pollution. In the past five years, the average annual sales volume is nearly 300 million. [0003] At present, there are many studies on the quality of snow mountain chicken, and there are many indicators measured, but they are not standardized and standardized, and it is difficult to reach an agreement,...
