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
