Two experiments were conducted to determine the apparent ileal digestibility (AID) and standardized ileal digestibility (SID) of AA and DE, and to estimate ME and NE of rice protein concentrate, salmon protein hydrolysate, whey protein concentrate, and spray-dried plasma protein. In Exp. 1, 6 barrows (initially 29.5 +/- 2.5 kg of BW) were fitted with ileal T-cannulas and fed each of 5 cornstarc...

The male pupae of Melon fly, Zeugodacus cucurbitae were irradiated at 30 Gy gamma radiation using Cobalt-60 source. Freshly emerged sterile males (30 Gy) exposed to different regimes methoprene and yeast hydrolysate as protein Sterile 10, 12 14 days old cue lure hydrolysate. Mating parameters such lek initiation, participation, calling, mating success female acceptance index (FAI) recorded. fed...

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 ...

Enzymatic hydrolysis led to improve functional properties and biological activity of protein by-products, which can be further used as protein ingredients for food and feed applications. The effects of proteolytic enzyme modification of egg-yolk protein preparation (YP) and white protein preparation (WP), obtained as the by-products left during the course of lecithin, lysozyme, and cystatin iso...

Actinopyga lecanora, a type of sea cucumber commonly known as stone fish with relatively high protein content, was explored as raw material for bioactive peptides production. Six proteolytic enzymes, namely alcalase, papain, pepsin, trypsin, bromelain and flavourzyme were used to hydrolyze A. lecanora at different times and their respective degrees of hydrolysis (DH) were calculated. Subsequent...

This study aims at preparing the Maillard reaction products of protein hydrolysate from grass carp (Ctenopharyngodon idella) bone and identifying its characteristic flavour compounds. Meanwhile, bioactivities amino acids composition hydrolysates were compared with thermal degradation as one positive control. Single factor experiment was applied to optimize enzymolysis parameters using flavourzy...

BACKGROUND The cladodes of Opuntia ficus-indica (prickly pear cactus) have a low protein content; for use as a balanced feed, supplementation with other protein sources is therefore desirable. We investigated protein enrichment by cultivation of the yeasts Candida utilis and Kluyveromyces marxianus in an enzymatic hydrolysate of the cladode biomass. RESULTS Dilute acid pretreatment and enzyma...

The whitefish industry generates a huge amount of rest raw material, which is currently wasted or underutilized in the production low-value products such as animal feed. While fish muscle primary product use for human consumption, material has great potential source protein and bioactive peptides food ingredients nutraceuticals. Enzymatic hydrolysis biotechnological processing method that can b...

Integrating of lignocellulose-based and starch-rich biomass-based hydrogen production was investigated by mixing wheat straw hydrolysate with a wheat grain hydrolysate for improved fermentation. Enzymatic pretreatment and hydrolysis of wheat grains led to a hydrolysate with a sugar concentration of 93.4 g/L, while dilute-acid pretreatment and enzymatic hydrolysis of wheat straw led to a hydroly...

Okara (tofu dregs) is a soybean waste product from the tofu and soymilk processing industry. To create useful product, remaining protein content in okara must be used. The goal of this study was to determine enzyme-substrate (E/S) ratio capable producing highest antioxidant activity hydrolysate, as well amino acid composition such hydrolysate (especially potential antioxidants). produce concent...
