Effects of Biofermented Feed on Zophobas morio: Growth Ability, Fatty Acid Profile, and Bioactive Properties

The global population’s increasing demand for sustainable and nutritious food sources has led to the exploration of alternative approaches in livestock production. Edible insects have emerged as a promising solution due their nutritional composition, including high protein content, balanced fats, minerals, vitamins, bioactive peptides. Biofermentation offers viable method enhance value insect feed. This study aimed investigate effects feeding biofermented feeds derived from less valuable raw materials on yield composition Zophobas morio larvae. focus was assessing fat quality, omega-3 omega-6 fatty acids, compounds monitoring larvae’s weight length increases. Three feed types were tested: wheat bran (control), fermented bran, mixture corn flaxseed five-week period. findings demonstrated noteworthy (p < 0.05) elevation polyunsaturated such gamma-linolenic acid, alpha-linolenic eicosapentaenoic acid larvae fed with pomace, both pre- postculinary treatment, compared control group. also showed increased chelation Cu2+ Fe2+ between native roasted samples without vitro digestion, well Cyclooxygenase-1 activity 0.05), indicating improved bioavailability. Additionally, culinary processing reduction polyphenol content antioxidant > except DPPH, peptide concentration digestion.
