Study on quality characteristics of longissimus muscle and biceps femoris muscle in Yanshan cashmere goats
摘要
Abstract
The study aimed to explore the differences in muscle quality characteristics between the longissimus muscle and the biceps femoris muscle of Yanshan cashmere goats.The experiment selected 10 Yanshan cashmere goats at the age of 30 months and measured their slaughter performance,muscle physicochemical properties,and nutritional components respectively.The results showed that the average pre-slaughter body weight of the Yanshan cashmere goats was 34.81 kg,with a carcass weight of 16.5 kg,a slaughter rate of 48.2％,an eye muscle area of 13.69 cm2,and a GR value of 7.43 mm.The crude protein content in the longissimus muscle was extremely higher than that in the biceps femoris(P＜0.01),while the intramuscular fat content in the biceps femoris was extremely higher than in the longissimus muscle(P＜0.01).The C18∶0 content in the longissimus muscle was extremely higher than in the biceps femoris(P＜0.01),and the C20∶0 content in the biceps femoris was significantly higher than in the longissimus muscle(P＜0.05).Correlation analysis showed that in the longissimus muscle,moisture content was extremely positively correlated with crude protein content(P＜0.01),and water loss was extremely negatively correlated with shear force(P＜0.01).In the biceps femoris,moisture content was significantly positively correlated with pH value(P＜0.05),water loss was significantly positively correlated with redness(a*)value(P＜0.05),the muscle a*value was extremely positively correlated with yellowness(b*)value(P＜0.01),lightness(L*)value was extremely positively correlated with b*value(P＜0.01),and intramuscular fat content was significantly negatively correlated with cooked meat yield(P＜0.05).The study suggests that the biceps femoris of Yanshan cashmere goats has more intramuscular fat deposition,while the longissimus muscle has a higher crude protein content.关键词
