background and objective: oxidative stress, due to free radicals, brings injury to the body by attacking large molecules and cell organs, and is the main reason of many diseases. fermentation of foods containing large amount of proteins such as milk by special species of lactic acid bacteria is a potential way in enhancement of the antioxidative activity of foods. this study aimed at evaluating...

Marine invertebrates, such as oysters, mussels, clams, scallop, jellyfishes, squids, prawns, sea cucumbers and sea squirts, are consumed as foods. These edible marine invertebrates are sources of potent bioactive peptides. The last two decades have seen a surge of interest in the discovery of antioxidant peptides from edible marine invertebrates. Enzymatic hydrolysis is an efficient strategy co...

Antioxidant peptides are gradually being accepted as food ingredients, supplemented in functional food and nutraceuticals, to positively regulate oxidative stress in the human body against lipid and protein oxidation. Meat muscle and meat by-products are rich sources of proteins and can be regarded as good materials for the production of bioactive peptides by use of enzymatic hydrolysis or dire...

Peptides derived from dietary proteins, have been reported to display significant antioxidant activity, which may exert notably beneficial effects in promoting human health and in food processing. Recently, much research has focused on the generation, separation, purification and identification of novel peptides from various protein sources. Some researchers have tried to discover the structura...

The goat placenta was fermented by Bacillus subtilis and the optimal fermentation parameters of strongest antioxidant capacity of peptides were obtained using response surface methodology (RSM). The effects of fermentation time, initial pH value and glucose content on the 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging capacity of the goat peptides were well fitted to a quadric equation...

BOBOEV, A., A. HASANOV, L. YOTOVA and H. HASANOV, 2012. Antioxidant activity of peptides obtained from wheat and cottonseed proteins. Bulg. J. Agric. Sci., 18: 103-111 Enzymatic hydrolysis of various wheat proteins and cottonseed with acid (Prolive PAC 30L “EnzymeBioProduct” Ltd, Russia) and neutral proteases (Neutrase, ‘’Novozymes’’, Denmark) was studied. The antioxidant properties of the prod...

Comprehensive comparison of antioxidant activity bioactive peptides produced from fish, poultry and shrimp wastes using Flavourzyme enzyme

Jellyfish (Rhopilema esculentum) was hydrolyzed using alcalase, and two peptides with angiotensin-I-converting enzyme (ACE) inhibitory and antioxidant activities were purified by ultrafiltration and consecutive chromatographic methods. The amino acid sequences of the two peptides were identified as VKP (342 Da) and VKCFR (651 Da) by electrospray ionization tandem mass spectrometry. The IC50 val...

In recent years, there has been considerable interest in bioactive peptides derived from food proteins, which might benefit human health. Pitaya and jiotilla are fruits with demonstrated biological functions its stem, peel, pulp. However, no studies have conducted to evaluate the peptides. The aim of this study was determine biofunctional properties (antioxidant, antihypertensive, antidiabetic ...
