摘  要:
本实验研究了真空冷却方式与冷风冷却,自然冷却方式对白煮牛肉品质的影响。样品中心温度从80℃冷却到10℃以下,与冷风冷却(120min)室温冷却(240min)相比较,真空冷却(24min)冷却速率较高。与常规冷却方式相比较,真空冷却的冷却损失较高,剪切力较大,硬度较大,弹性较低,色泽较差。感观分析表明,真空冷却样品总体可接受性不及常规冷却样品。微生物检测表明,真空冷却能显著降低菌落总数,减少细菌增殖,保证样品的卫生质量。

摘  要:
The influence of vacuum cooling on the quality of cooked beef was studied as compared with conventional cooling methods including air-blast cooling and slow-air cooling.Samples were cooked until core temperatures reached above 80℃ then cooled down to core temperature below 10℃.The results showed that vacuum cooling was very rapid (24min) compared with air-blast (120min) and slow-air (240min).The chill loss was higher for vacuum cooling samples compared with conventional cooling.Instrumentalt exturei ndicatedt hata h ighershear force and lower springiness for vacuum cooling samples.Sensory analysis showed that the conventional cooling samples have better overall acceptability.H owever,thea nalysiso fm icrobiol-ogy indicated vacuum cooling samples have the lowest total number of colonies and decrease the multiplication of these colonies to protect the sanitation.
