Improving insect meal nutrition
Feeding medium and nutritional supplementation into BSF (Black Soldier Fly) and YMW (Yellow Mealworm) strongly influences the nutritional composition of insect meal. Protein content and the accumulation of unsaturated fats, which are of great interest to consumers, have been found to depend directly on the substrate composition and supplements added during insect rearing.
Improving nutritional intake
Influencing these parameters is extremely relevant for our industry, considering the prevalence of human diseases associated with saturated fatty acids and trans fats. The addition of Actisaf® Sc 47 in the rearing substrate decreases the concentration of saturated acids (12.0 and 14:0), and the amount of trans fat acids in insect meal; at the same time, it increases linoleic acids (18:2n-6) and polyunsaturated fatty acids. This is a significant contribution to insect meal valorisation, given the human disease risk mentioned above. Conversely, polyunsaturated fatty acids are considered good fats, reducing the risk of cardiovascular disease in humans.
