Flavor profile of “Dao Ban Xiang” (a traditional dry‐cured meat product in Chinese Huizhou cuisine) at different processing stages in winter and summer

Abstract

Abstract“Dao Ban Xiang” is a famous traditional Chinese dry‐cured meat product. This study aimed to comparatively analyze the difference in the volatile flavor information of “Dao Ban Xiang” produced in winter and summer. In this study, we determine the physical and chemical properties, free amino acids (FAAs), free fatty acids (FFAs), and volatile compounds in the four processing stages of samples in winter and summer. The content of FAAs decreased significantly during the curing period in winter while increasing steadily in summer. The content of total FFAs increased in both winter and summer, and polyunsaturated fatty acids (PUFAs) decreased significantly in summer. The characteristic compound in winter samples is hexanal, nonanal, and (E)‐2‐octenal, which may mainly come from the degradation of FAAs, while the characteristic compound in winter samples is hexanal, nonanal, and (E)‐2‐nonenal, which may mainly be derived from the oxidation of FFAs. This study extends our knowledge on flavor from traditional cured meat products at different processing stages in different seasons and could be useful for the standardization of the traditional and regional meat products.
