In the present work, macadamia protein was enzymatic hydrolyzed to produce peptides which had abundant antioxidant activities. The relative antioxidant capacity was investigated through some in vitro models such as scavenging activity of DPPH radical, scavenging of ABTS+ radical and evaluation of the total antioxidant capacity assay. Macadamia protein was characterized by methods of DEAE cellul...

Marine fish provide a rich source of bioactive compounds such as proteins and peptides. The bioactive proteins and peptides derived from marine fish have gained enormous interest in nutraceutical, pharmaceutical, and cosmeceutical industries due to their broad spectrum of bioactivities, including antioxidant, antimicrobial, and anti-aging activities. Recently, the development of cosmeceuticals ...

Bioactive peptides have been identified in a range of foods, including plant, milk and muscle, e.g., beef, chicken, pork and fish muscle proteins. Bioactive peptides from food proteins offer major potential for incorporation into functional foods and nutraceuticals. The aim of this paper is to present an outline of the bioactive peptides identified in the muscle protein of meat to date, with a ...

Microenvironmental factors may influence the antioxidant efficacy of food-derived peptides. This study evaluated in vitro properties peptides released during ripening (9 to 24 months processing) Spanish dry-cured ham (Biceps femoris muscle) assisted by spectral-chromatographic methodologies. Results indicated that 2,2?-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) radical-cation (ABTS?+) qu...

Whey is a highly polluting by-product of cheese processing. However, it has valuable nutritional properties since rich and balanced source proteins amino acids. Therefore, broad range functional that can be exploited for diverse applications. Research shown how the enzymatic hydrolysis whey releases bioactive peptides. In present study, protein concentrate (WCP) was performed using purified Spo...

Nowadays, the search for food-suitable plant proteins is a great challenge. In addition to their sustainability and nutritional value, focus more on possible positive interactions with human health. To date, presence of bioactive peptides encrypted in structure protein opens new perspectives, addressing food industry’s request ingredients technological properties also nutraceutical pharmaceutic...

BACKGROUND A plant mixture containing indigenous Australian plants was examined for synergistic antimicrobial activity using selected test microorganisms. This study aims to investigate antibacterial activities, antioxidant potential and the content of phenolic compounds in aqueous, ethanolic and peptide extracts of plant mixture. METHODS Well diffusion, minimum inhibitory concentration (MIC)...

Today, the usage of natural additives in food matrix has increased. Natural antimicrobial compounds include peptides, enzymes, bacteriocins, bacteriophages, plant extracts, essential oils, and fermented that can be used as alternatives to chemical antimicrobials. Plant extracts oils contain terpenes, flavonoids, aldehydes, phenolic cause antioxidant activity. The synergistic activity synthesize...
