Malaysia is one of the main producers duck meat globally with increasing demands. Increasing in production will also increase number by-products such as skin, feet and bones. Pekin (Anas platyrhyncos domestica) famous breeds. Gelatin that was extracted from has shown a potential raw material for bioactive peptide can involve various functions organism physiologically example antioxidant effects...

Pumpkin protein meal was hydrolysed by alcalase, flavourzyme, protamex and neutrase. Physicochemical characteristics were evaluated by previously published methods using pumpkin protein hydrolysates (PPHs) and pumpkin protein meal (PPM) as a control. Hydrolysis had significantly changed the physicochemical characteristics of protein meal and its functionality as well. Different enzymes had diff...

The stone fish (Actinopyga lecanora) ethanolic and methanolic tissue extracts were investigated for total phenolic contents (TPCs) as well as antioxidant activity using 2,2-diphenyl-1-picrylhydrazyl (DPPH(•)) radical scavenging activity and ferric reducing antioxidant power (FRAP) assays. Both extracts showed low amount of phenolics (20.33 to 17.03 mg of gallic acid equivalents/100 g dried samp...

In the current investigation, fresh trout viscera and smoked trimmings were enzymatically extracted using papain, alcalase, protamex, flavourzyme. Protein extraction was performed at different concentrations (0.5%, 1%, 1.5% 2%) times (30 minute, 1 hour 4 hours). The moisture, crude protein, lipid ash contents of used as raw materials, in study, respectively found 60.26±0.78%, 12.18±0.21%, 31.18...

The study aimed to investigate the effects of alcalase, papain, flavourzyme, and neutrase on structural characteristics bioactivity stability Cucumaria frondosa intestines ovum hydrolysates (CFHs). findings revealed that flavourzyme exhibited highest hydrolysis rate (51.88% ± 1.87%). At pH 2.0, solubility hydrolysate was lowest across all treatments, while at other levels over 60%. primary stru...

• Silkworm protein hydrolysates were generated with a range of proteolytic enzymes. The resulting physicochemical properties the enzyme dependent. demonstrated in vitro and situ antioxidant activity. In total, 8 peptides synthetised examined for cellular SWFVTPF NDVLFF showed highest activity HepG2 cells. ( Bombyx mori ) pupae is by-product from silk industry which rich protein. Hydrolysates si...

Soybean allergy is of great concern and continues to challenge both consumer and food industry. The present study investigates the enzyme-assisted reduction in major soybean allergens in soy protein isolate using different food-grade proteases, while maintaining or improving the sensory attributes and technofunctional properties. SDS-PAGE analyses showed that hydrolysis with Alcalase, Pepsin, a...

Synthetic angiotensin I-converting enzyme (ACE-I) inhibitors can have undesirable side effects, while natural inhibitors have no side effects and are potential nutraceuticals. A protein-rich fraction from chia (Salvia hispanica L.) seed was hydrolyzed with an Alcalase-Flavourzyme sequential system and the hydrolysate ultrafiltered through four molecular weight cut-off membranes (1 kDa, 3 kDa, 5...

The antioxidant activity of flaxseed protein hydrolysates obtained using five different enzymes was evaluated. Proteins were isolated from flaxseed cake and were separately treated with papain, trypsin, pancreatin, Alcalase and Flavourzyme. The degree of hydrolysis (DH) was determined as the percentage of cleaved peptide bonds using a spectrophotometric method with o-phthaldialdehyde. The distr...

A comparative study of enzymatic hydrolysis of dry wheat gluten was carried out by exoprotease and endoprotease enzyme praparations. Gluten of different rheological properties was conditionally divided into three groups on the basis of the compressive deformation index (Hdef) determined with the IDK-1 instrument: shortcleaved (Hdef 40 instr. units), good (Hdef 65 instr. units) and weak gluten (...
