RESUMO:

Worldwide, there is a growing need to seek alternative sources of food in addition to those traditionally used. This demand has led to considerable interest in edible insects, which are already part of the cultures and diets of many countries, in addition to representing an excellent sustainable source of essential nutrients. The consumption of insects as food is practiced in several regions, and in Brazil more than 130 species of edible insects belonging to nine orders have already been registered, among which are the Hymenoptera and Coleoptera. Of this order, the highlights are Atta sexdens (ant) and Pachymerus nucleorum (coconut larva). Given the above, the objective of this work was to characterize two species of edible insects (Atta sexdens and Pachymerus nucleorum) traditionally consumed in Brazil, in order to know their nutritional potentials for insertion as an alternative food in the human diet. For this, the insects were evaluated on a wet basis (in natura), as well as through the preparation of whole and defatted flours. Physical-chemical analyzes (moisture, proteins, lipids, ash, crude fiber, water activity and fatty acid profile), antioxidants (phenolic compounds, flavonoids and DPPH) and microbiological (Coliforms at 35 ° C and 45 ° C, Molds and Yeast, Mesophiles, Salmonella sp. and Escherichia coli). The results showed that proteins (39.01% and 26.14%) and lipids (28.20% and 52.19%) were the major components, followed by fibers (23.57% and 14.51%) for A. sexdens and P. nucleorum respectively. In addition, the insects showed high percentages of unsaturated fatty acids (A. sexdens - 76.12% and P. nucleorum - 47.23%), with emphasis on the essential fatty acid C18: 2n-6 (A. sexdens - 61, 46% and P. nucleorum - 7.19%), which was higher than that of beef in both species. P. nucleorum larvae had a high content of phenolic compounds (836.39 mg GAE / 100 g) and antioxidant activity (44.33%), with values higher than those of traditional fruits. The effects show that the species analyzed can be considered viable as an alternative source of food, as they have potential nutritional value, and should therefore be exploited as a natural and renewable resource for human consumption.
