Blood is the main by-product from slaughterhouses bearing high levels of suspended solids (18% w/w) and BOD5 (250 000–375 000 mg O2/L), which makes difficult its handling disposal. This study proposes valorisation blood protein to produce enzymatic hydrolysates rich in haemic iron antioxidant peptides. Haemic presents higher bioavailability compared inorganic form, but incorporation into foodst...

Peptides are biomolecules composed of amino acids linked through peptide bonds present in proteins. These peptides may have biological activities associated with their secondary structure, especially when released from the original protein sequence. The prospect these is subject study and research various sectors, including food pharmaceutical industries. This due to possibility using them as s...

Argentine croaker (Umbrina canosai) and chicken (Gallus domesticus) bones were hydrolyzed with different proteases (Flavourzyme, "-Chymotrypsin and Trypsin) in order to obtain peptides whit antioxidant activity. The hydrolysates showed different degrees of hydrolysis and antioxidant activity. The antioxidant power of the hydrolysates was evaluated through inhibition of the peroxidation of linol...

BACKGROUND Antioxidant and chelating activities were determined in protein hydrolysates that were produced by treating a protein isolate of a non-toxic genotype of Jatropha curcas with the protease preparation alcalase. RESULTS 50 min protein hydrolysate with a degree of hydrolysis of 31.7% showed highest antioxidant and chelating activity. These activities were also determined in six peptidi...

Cocoa and cocoa products have received much attention due to their significant polyphenol contents. Cocoa and cocoa products, namely cocoa liquor, cocoa powder and chocolates (milk and dark chocolates) may present varied polyphenol contents and possess different levels of antioxidant potentials. For the past ten years, at least 28 human studies have been conducted utilizing one of these cocoa p...

Marine collagen peptides (MCPs) are natural products prepared by hydrolyzing marine protein through a variety of chemical methods or enzymes. MCPs have range structures and biological activities widely present in species. also small molecular weight, easily modified, absorbed the body. These properties attracted great interest from researchers studying antioxidant, anti-tumor, anti-aging activi...

The antioxidant activity and cell viability of feather hydrolysates obtained with the Bacillus licheniformis were evaluated using an in-vitro model. results indicate that feathers-derived peptides under 3 kDa have IC50 values 5.03 ± 0.215 mg/mL by DPPH assay. Although preserved after applying diverse heating (from 20 to 100 °C), they lost their strongly acidic or alkaline conditions. Antioxidan...

Abstract Milk from different species has been exploited for the isolation of various functional ingredients decades. Irrespective source, milk is considered as a complete food, it provides essential nutrients required by human body. Proteins and their fractions are valuable sources bioactive peptides that might exert health beneficial role in body such immune-modulation, antioxidant activity, A...

Bioactive peptides are short amino acid sequences, that upon release from the parent protein may play different physiological roles, including antioxidant, antihypertensive, antimicrobial, and other bioactivities. They have been identified from a range of foods, including those of animal origin, e.g., milk and muscle sources (with pork, beef, or chicken and various species of fish and marine or...

Marine bioactive peptides, as a source of unique bioactive compounds, are the focus of current research. They exert various biological roles, some of the most crucial of which are antioxidant activity, antimicrobial activity, anticancer activity, antihypertensive activity, anti-inflammatory activity, and so forth, and specific characteristics of the bioactivities are described. This review also...
