example 1

[0110] 500 mg / L vanillin amine and 500 mg / L individual fatty acids were fed to E. coli cultures overexpressing the ACS1 and CS genes of ghost pepper. Produced samples were taken one (1) and two (2) days after substrate feed and analyzed by high performance liquid chromatography (HPLC) (see figure 2 ).

[0111] Such as figure 1 and figure 2 As shown, the result of this experiment was the production of nonanoylamide and other capsaicinoids. NV is the amide of geranic acid (n-nonanoic acid) and vanillyl nonamide. Vanillyl nonamide is widely used as a spicy food additive and as a medicine for arthritis and muscle pain relief.
