Sažetak
Insects are nowadays becoming globally interesting as a protein and fat source for humans, production animals (currently aquaculture) and pet animals (insectivores). Among commercially interesting species we investigated Jamaican field cricket (Gryllus assimilis) due to the resistance to Acheta domesticus densovirus (AdDNV) and Black soldier fly (Hermetia Illucens) due to the high versatility in feeding media that can be used for its rearing. Our main goal was to investigate to which extent dietary manipulation could improve the fatty acid profile of these species. The insects were reared using feed with different oil blends (sunflower, fish, linseed oil) and additionally, Black soldier fly larvae were reared using different byproducts (crude olive cake, processed animal protein) as feeding media. The analysis of fatty acid composition was performed using a Shimadzu GC-MS QP2010 Ultra Gas Chromatograph Mass Spectrometer equipped with capillary column BPX70. For statistical data analysis, Statistica 2012 was used. Data were compared by analysis of variance and Tukey post hoc test. The highest plasticity was found in seven different fatty acids and n6/n3 ratio. In Black soldier fly larvae plasticity was very high and the highest in the content of lauric acid. In Jamaican field cricket plasticity was lower compared to the Black soldier fly larvae and the highest was in the content of linolenic acid. High plasticity in the lipid profile of Hermetia illucens and Gryllus assimilis could be achieved by using different oils and byproducts in their feed. These changes could add significant value to the insect production including improved quality of insects as the feed for production animals and pets as well as the source of specific oils for different industries.
