低钠干腌肉加工过程中肌内结缔组织特性
Characteristics of Intramuscular Connective Tissue in Low Sodium Dry-Cured Meat during Processing
摘要
Abstract
The effect of low sodium salt on intramuscular connective tissue (IMCT) during the processing of dry-cured pork from M.longissimus dorsi was investigated.At the end of post-ripening,the thickness of secondary perimysium of low sodium-cured samples was 0.72 μm lower (P < 0.05),and the thermal solubility of collagen was 0.91% higher than that of normal salt-cured samples (P < 0.05).On the other hand,no significant differences existed in total collagen,the thickness of primary perimysium or pyridinoline cross-linking between the two groups (P > 0.05).Compared with the normal salt group,the relative contents of α-helix and β-turn in the low sodium group were decreased by 11.69% and 13.41%,respectively (P < 0.05);in contrast,aggregated strands and random coil were increased by 46.88% and 5.82%,respectively (P < 0.05).In conclusion,low sodium salt can further promote the degradation of IMCT than normal salt during the processing of drycured pork.关键词
