AB  - The effect of addition of different levels of lotus leaf powder on the flavor of dried minced pork slices (DMPS) was studied by examining its sensory flavor attributes, flavor substances, lipid and protein oxidation levels, Maillard reaction degree, and microstructure. The results showed that addition of lotus leaf powder significantly affected the flavor of DMPS. Addition of lotus leaf powder at 0.2% and 0.4% improved the flavor of DMPS by inhibiting the oxidation of lipids and proteins and consequently reducing the contents of the fat rancidity flavor compounds hexanal and nonanal, and the fishy odor compound trimethylamine. The generation of phenethyl alcohol, (E)-2-hexenal, and methyl acetate provided DMPS with a delicate fragrance of lotus. However, adding 0.6% or 0.8% lotus leaf powder significantly decreased the contents of sweet amino acids and the umami taste intensity of DMPS, and exacerbated lipid and protein oxidation by disrupting the microstructure of DMPS. Furthermore, lotus leaf powder suppressed the production of volatile heterocyclic compounds in DMPS by inhibiting the Maillard reaction. Therefore, addition of an appropriate amount of lotus leaf powder could effectively improve the flavor of DMPS.
