Lizard fish protein hydrolysates (LFPH) were prepared from Lizard fish (Saurida elongata) proteins possessing powerful angiotensin I converting enzyme (ACE) inhibitory activity and the fraction (LFPH-I) with high ACE inhibitory activity was obtained through ultrafiltration. The active Fraction (F2) was isolated from LFPH-I using immobilized metal affinity chromatography (IMAC-Ni2+). Analysis of...

Sea products are valuable resources of natural substances such as lipids, polysaccharides, enzymes, vitamins, and proteins. In this issue, a variety of fish proteases (trypsin, alcalase, etc.) have been characterized and sometimes purified. Many of these enzymes display potentially interesting new biochemical properties for industrial applications. Their potential adequacy for biotechnological ...

Foods that account for 90% of allergic reactions in children are cow's milk protein, eggs, peanut, soy, tree nuts, fish, and wheat. Food allergy can manifest as urticaria/angioedema, anaphylaxis, atopic dermatitis, respiratory symptoms, or a gastrointestinal (GI) disorder. GI allergic manifestations can be classified as immunoglobulin E (IgE) mediated (immediate GI hypersensitivity and oral all...

Protein can be hydrolyzed, producing small chains of amino acids called peptides. Several studies have shown that protein hydrolysates containing mostly di- and tripeptides are absorbed more rapidly than free form amino acids and much more rapidly than intact proteins. In addition, there is recent evidence that protein hydrolysate ingestion has strong insulinotropic effect. Thus, recovery sport...

Currently valorization of fish discards by-products is becoming fundamental for the sustainable management fisheries and seafood transforming industries. Thus, we have studied changes in production chemical properties protein hydrolysates (FPH) oils from (heads (He) skins + bones (SB)) gurnard (Trigla spp.) captured at different seasons. Hydrolyses were performed by Alcalase (2.5 mL/kg by-produ...

Casein and soy protein were digested by papain to three degrees of hydrolysis (DH) 7.3%-13.3%, to obtain respective six casein and soy protein hydrolysates, aiming to clarify their in vitro proliferation and anti-apoptosis towards a human osteoblastic cell line (hFOB1.19 cells). Six casein and soy protein hydrolysates at five levels (0.01-0.2 mg/mL) mostly showed proliferation as positive 17β-e...

Iron (Fe) is an essential micronutrient for human growth and health. Organic iron is an excellent iron supplement due to its bioavailability. Both amino acids and peptides improve iron bioavailability and absorption and are therefore valuable components of iron supplements. This review focuses on protein hydrolysates as potential promoters of iron absorption. The ability of protein hydrolysates...

Catfish skin is an abundant and underutilized resource that can be used as a unique protein source to make fish skin protein hydrolysates. The objectives of this study were to isolate soluble and insoluble proteins from hydrolyzed catfish skin, study the rheological and functional properties of the protein hydrolysates, and evaluate the properties of emulsions made from the protein powders. Fre...
