摘要: The main taste compounds of the water-soluble extract (WSE) dry-cured ham are free amino acids (FAAs) and small peptides. At present there many extraction methods for WSE with pure water, HCl–ethanol, ethanol, alkaline boiled water as solvent. These were studied on basis FAAs, recovery peptides volatile index. Results showed Jinhua extracted using had highest percentage (19.57%) molecular weight 200–300 Da. Most importantly it most similar characteristics to raw during sensory evaluation; salt sweet taste. In addition, was high (36.11%), though method much more effective (37.05%), astringent dominated evaluation. Otherwise, from viewpoint we could see they mainly provide umami Considering interactions between aroma compounds, latter obtained five identified significant differences noted.
