摘要:

采用不同的加盐量(3%、4%、5%)腌制肉块,定期检测其理化指标。结果发现:加盐量不影响最终产品(30d)的水分含量(55% 左右),但对其他指标却有不同程度的影响,加盐量越低,蛋白水解指数越高,挥发性盐基氮含量越高,TBA 值越小;所有肉块在30d 时的氯化钠含量(湿基)均在5.5%~8.7% 范围内,与我国传统干腌肉制品(如宣威火腿)相比,已经有不同程度的下降。

关键词: 干腌肉块, 水分含量, 氯化物含量, TBA值, 挥发性盐基氮

Abstract:

In order to study effects of salt amount on physico-chemical characteristics of cured meat pieces, different amounts of salt (3%, 4% and 5%, respectively) were added into meat and physico-chemical properties were evaluated at the fixed periods. Results showed that different salt amounts had different effects on all properties of the final products except for water content (about 55%). Less addition of salt resulted in higher proteolysis index, higher total volatile basic nitrogen (TVB-N) and lower thiobarbituric acid (TBA). In addition, NaCl content in all products post-treatment for 30 days was in the range of 5.5% - 8.7%, which was much lower than that of Chinese traditional dry-cured meat products such as Xuanwei ham.

Key words: dry-cured meat, water content, NaCl content, TBA, TVB-N
