Black Soldier Fly (Hermetia illucens) Prepupa Phase Fermentation by Organic Acids to Decrease Chitin Content

Black Soldier Fly has high protein but there are anti-nutrients, namely the presence of chitin content that cannot be digested by livestock such as poultry and monogastrics. Chitin is a natural polysaccharide abundantly found from crustacean organisms insects. usually bound to shell or exoskeleton, proteins, minerals pigments. in prepupa phase protein, dark brown body rather hard exoskeleton which causes content. The aim this research was determine concentration propionic formic acids could reduce (Hermetia illucens) fermentation. This study used completely randomized design (CRD) with five treatments, P1 = (BSF added 50% acid + acid), P2 80% 20% aquadest), P3 60% 40% P4 P5 aquadest) three repetitions. results indicate treatment (addition acid) resulted lowest reduction content, (11.00%), pH value (4.7), total titrated (0.014%) organoleptic (light color, very sour aroma harsh texture).
