All values are mean±SD of three replicates (n=3).
Means within a column with different letters are significantly different (p<0.05).
All edible insect was freeze-dried defatted larvae powder (TM, Tenebrio molitor; AD, Allomyrina dichotoma; PB, Protaetia brevitarsis seulensis) and W and S meant water (0.02% ascorbic acid) and salt soluble (0.56 M saline solution).
EAA, essential amino acid.
