摘要: 选取优一级、优二级和普通级中国黄牛牛胴体的外脊,测定其在成熟0、1、3、7、14、21和30h的剪切力值、pH、解冻滴水损失、蒸煮损失和熟肉率。结果表明,等级和成熟时间对外脊剪切力值有显著影响(p<0.05),等级对解冻滴水损失、蒸煮损失和熟肉率有极显著影响(p<0.01)。在同一成熟时间,级别越高,剪切力值越小,解冻滴水损失和蒸煮损失越小,熟肉率越高;随着成熟时间的延长,牛肉的剪切力值显著降低,解冻滴水损失和蒸煮损失显著增大(p<0.01)。

Abstract: The Chinese yellow cattle carcass quality grades 2,3 and 4 were selected, and the quality traits of the striploins were studied. Results showed that the shear force value of each grade striploin was significantly varied(p<0.05), and the water-holding capacity was significantly different(p<0.01). At certain aging time, the higher the grade was, the better the tenderness and the water-holding capacity were. As aging time extended, the shear force value decreased and the water-holding capacity increased.
