Abstract:
High sodium intake poses health risks, highlighting the necessity for effective sodium reduction in meat processing. This study investigated the impact of basic amino acids (l-lysine, L-arginine, L-histidine) as flavor enhancers on the flavor of low-sodium salted goose. The combined use of KCl and basic amino acids achieved a sodium reduction of 36.51 %. Basic amino acids significantly inhibited lipid oxidation, reducing TBARS by up to 40.60 %, likely due to suppressed lipoxygenase activity (from 186.05 to 113.78 U/(min·g)). GC-MS analysis revealed that aldehydes and alcohols, the dominant volatile compounds, decreased by 15.07 % and 12.64 %, respectively, thereby mitigating undesirable odors. Intelligent sensory and quantitative descriptive analyses confirmed that basic amino acids effectively masked KCl-induced bitterness and astringency while enhancing saltiness and umami perception. This study demonstrates the flavor-improving effects of basic amino acids in low-sodium salted goose, providing a practical strategy for developing healthier, low-sodium meat products.
