The β-naphthylacetate test for insect contamination of foods

Abstract

Carboxyesterase activity was observed in three species of insects (Plodia interpunctella, Tribolium castaneum, Megaselia spiracularis) at two different temperatures. The reaction was detected by β-naphthylacetate. This enzyme activity seems to be useful for presumption of the mixing time of the insect in the food.
