Effect of Three Defatting Solvents on the Techno-Functional Properties of an Edible Insect (Gryllus bimaculatus) Protein Concentrate

Edible insects have received global attention as an alternative protein-rich here food.However, their structural characteristics make them difficult to digest.To overcome this obstacle, we assessed the techno-functional properties of three protein concentrates from the cricket Gryllus bimaculatus.

Freeze-dried G.bimaculatus powder was defatted using ethanol, hexene, or acetone as solvents, and the techno-functional properties (protein solubility, water and oil holding capacity, foaming properties, emulsion capacity, and gel formation) of the protein concentrates were determined.Freeze-dried G.

bimaculatus powder comprised approximately 17.3% crude fat and 51.3% crude protein based on dry weight.

Ethanol was the most effective solvent for reducing the fat content (from 17.30% to 0.73%) and increasing the protein content (from 51.

3% to 62.5%) of the concentrate.Techno-functionality properties drastically differed according to the defatting solvent used and foaming dorisvale station for sale properties were most affected.

Thus, the techno-functional and whole properties must be considered for proper application of edible insects to achieve global food sustainability.
