Study on the Transition of Meat Color From Shanzhu Crossbred
摘要
Abstract
The study was to investigate the meat color change of M. longissimus dorsi （LD） from three kinds of Shanzhu crossbred. The results showed that meat color score and a ^＊ value （Red） in three-way cross swine were higher than those in two-way cross swine. Also boar meat was more reddish than sow＇ s. Comparing marbling score and b^ ＊ value （Yellow） between crossbreds and gender, both index indicated that sow meat was more fat than boar＇ s. Pork in two-way cross swine contained more fat than that in three-way cross＇ s. pH24 was negatively correlated with b ^＊ value and drop loss（ P 〈 0. 05 ）. It was also found that the higher b^ ＊ value was, the lower drop loss was. A regression equation was built between meat color score （Y） and L （ Light, X1 ）, a^＊ （X2 ）, b^＊ （ X3 ） value, Y = 6. 83 - 0. 107X1 - 0. 027X2 ＋ 0. 261X3 （ R = 0. 597,P 〈 0. 05 ）. From this mathematics model, the contribution rate of L and b^＊ value for meat color was more than a^ ＊ value. Conclusion was that meat color in three-way cross （ 1/4 inherited Shanzhu） was more reddish or ideal, while in two-way cross （ 1/2 inherited Shanzhu） was more yellowish or fatty.关键词
