Optimization and Characterization Freeze Dried Fish Protein Hydrolysate Production

چکیده
The production of fish protein hydrolysate from underutilized species is attracting the industrial interest for increasing rich values. central composite design was used to optimize degree enzymatic hydrolysis freeze-dried (FPH) by application commercial Alcalase on recovery mixed small protein. effects time, temperature, pH and enzyme concentration (DH) five strains as Rastrelliger brachysoma (short-bodied mackerel), kanagurta (Indian Leiognathidae (Ponyfish), Amblygaster leiogaster (Smooth belly sardinella) Selaroides leptolepis (yellow-stripe scad) were experimented. Result showed that FSH optimized at 2.85%v/w 61 °C, 8.50 27 min with 89.42% DH. Mathematical model proposed validated under optimum condition. high proportion (46.43%) smaller molecular weight <1 kDa found in hydrolysate. Freeze-dried produced revealed three predominant amino acids glutamine, lysine alanine. Based acid compositions, waste nutritional value potential applications feed supplementation.

Freeze-dried B.C.G. of British manufacture became available for experimental work in 1955. The main reason for introducing it was the need for a vaccine which would retain its potency under conditions of prolonged storage. On reconstitution for injection the vaccine should produce a uniform suspension with minimal clumping, resulting in a uniform viable bacterial count. These properties mean th...
