摘要:

以西门塔尔牛肉为原料,研究150 MPa超高压处理对冰温保鲜牛肉品质的影响,为开发新型牛肉保鲜方式提供参考。结果表明:经过150 MPa超高压在20 ℃条件下处理15 min后的冰温贮藏过程中,牛肉的感官评分高于对照组,质构、蒸煮损失率、pH值等指标的变化趋势均慢于对照组,超高压处理牛肉的贮藏期可达到32 d,比对照组延长7 d。超高压处理有利于延长牛肉的冰温保鲜时间。

Abstract:

This study was performed to investigate the effect of high pressure treatment at 150 MPa on the quality of
Simmental beef stored at ice temperature (-2 ℃). The results showed that the sensory scores of beef treated by 150 MPa at
20 ℃ for 15 min were higher than those from the control group. Compared with the control group, the changes in texture,
cooking loss rate and pH of beef treated by the high pressure were less obvious. The storage life of 150 MPa-treated beef was
32 days, which was prolonged by 7 days compared with the control group. It can be concluded that high pressure is beneficial
for prolonging the storage life of the beef at ice temperature.

Key words: beef, high pressure treatment, ice temperature, quality
