Reducing NaCl content in food while maintaining acceptability poses a significant challenge. Odor-induced saltiness enhancement (OISE) emerges as a promising solution. This study utilized gas chromatography-olfactory (GC-O) in conjunction with gas chromatography-mass spectrometry (GC-MS) to identify 37 key volatile compounds in three representative Chinese dry-cured hams. These compounds had an odor activity value (OAV) of ≥1 or a modification frequency (MF) of ≥30%. Subsequently, quantitative descriptive analysis (QDA) identified eight odorants associated with saltiness. These included 1-octen-3-ol, nonanal, heptanal, 2-methylbutanal, 3-methyl-butanal, benzaldehyde, octanal, and 2,6-dimethylpyrazine. Remarkably, these odorants significantly intensified saltiness (P < 0.05) when added to a low-concentration NaCl solution (0.3%), compared to zero or high concentrations (0.75% and 0.8%). As a result, traditional Chinese salty meat products offer a promising source of odorants for enhancing saltiness, compensating for reduced NaCl content through OISE.
在保持可接受性的同时降低食品中的氯化钠含量是一项重大挑战。气味诱导咸味增强(OISE)成为一种有前景的解决方案。本研究利用气相色谱-嗅觉分析(GC-O)结合气相色谱-质谱联用(GC-MS)来鉴定三种代表性中式干腌火腿中的37种关键挥发性化合物。这些化合物的气味活性值(OAV)≥1或修饰频率(MF)≥30%。随后,定量描述分析(QDA)确定了八种与咸味相关的气味物质。其中包括1-辛烯-3-醇、壬醛、庚醛、2-甲基丁醛、3-甲基丁醛、苯甲醛、辛醛和2,6-二甲基吡嗪。值得注意的是,与零浓度或高浓度(0.75%和0.8%)相比,当将这些气味物质添加到低浓度氯化钠溶液(0.3%)中时,咸味显著增强(P < 0.05)。因此,传统中式咸肉产品为通过OISE增强咸味、补偿降低的氯化钠含量提供了一种有前景的气味物质来源。
