自然放牧条件下不同月龄巴音布鲁克羊肉品质的比较分析
Comparative analysis of meat quality of Bayinbruk sheep of different months of age under natural grazing conditions
摘要
Abstract
[Objective]To compare the meat quality and characteristics of Bayinbuluk sheep of different months old under natural grazing conditions.[Methods]Six 6-month and 9-month-old male lambs under natural grazing conditions were randomly selected for slaughter,and the pH,chromaticity,cooking loss,shear force,conventional nutrients,amino acids and fatty acids contents of the longest dorsal muscle were deter-mined and analyzed.[Results]The meat brightness(L*),redness(a*),yellowness(b* values)and shear force values at 9-month-old were extremely significantly higher than those at 6-month-old(P＜0.01),and the pH and cooking loss had no significant differences;The meat composition of protein,fat,and water had no significant differences between 6-months-old and 9-months-old(P＞0.05),the essen-tial,nonessential and total amino acids content were extremely significant higher at 6-months-old than at 9-months-old(P＜0.01),and the polyunsaturated fatty acid content was significant higher at 9-months-old than at 6-month-old(P＜0.01).[Conclusion]There is a big difference in meat quality and nutrient composition between Bayinbruk lambs of different months old,the meat from 6-months-old lambs is of good tenderness,and that from 9-months-old lamb has the perfect lustrousness and good nutritional value.The quality and nutrition of different months at 6 months is of good quality and high tenderness;that at 9 months has bright luster and high nutritional value.关键词
