Última Production factors affecting antioxidant peptides from tilapia processing byproducts Ciênc. Tecnol. Aliment. WACHIRATTANAPONGMETEE,Kwanruedee; KATEKAEW,Somporn; SAE-EAW,Amporn; THAWORNCHINSOMBUT,Supawan. Abstract This research aimed to elucidate significant factors affecting antioxidant capacity of protein hydrolysates from tilapia processing byproducts. Effects of protein type, substrate concentration (0.4-1.2%) and time of hydrolysis (0-60 min) on antioxidant abilities were investigated. Antioxidant activity of the alkaline-aided protein hydrolysate (APH) hydrolyzed by Protease G6 at 1.2% and 60 min hydrolysis was comparable to the control (minced tilapia muscle hydrolysates) and was more effective than the myofibrillar protein and sarcoplasmic protein hydrolysates. Principal component analysis showed that the APH exert their antioxidant capacity by peroxyl radical quenching ability. These findings provide evidence that the APH from fish byproducts can...

The effects of m-calpain isolated from the skeletal muscle of sea bass on sarcoplasmic and myofibrillar proteins isolated from the same tissue were examined in vitro. Incubation of sarcoplasmic proteins with m-calpain resulted in only a slight decrease (0.7 kDa) in the molecular weight (MW) of a 26.5 kDa protein. Degradation of myofibrils, monitored by quantification of TCA-soluble peptides generated, resulted in the maximum amount of peptides being generated after 1 h of incubation at 25degreesC. Noticeable modifications in the SDS-PAGE profile of digested myofibrils were observed, including partial denaturation of myosin heavy chain and the release of tropomyosin, similar to69 and similar to27 kDa doublet bands and a few polypeptides of MW lower than 20...
