Antioxidant encapsulation can be used to protect the nutritional

Copanlisib solubility dmso and sensory quality of food and/or to protect the body against chronic diseases related to aging [20•]. Fish protein hydrolysates possess antioxidant activity and the ability to scavenge hydroxyl radicals, superoxide anion radicals, hydrogen peroxide, and chelate metal ions [32]. Small peptides show higher antioxidant capacity than native proteins and may be absorbed in the intestine without further digestion. The results obtained so far suggest that the hydrolytic treatment of this industrial by-product, with selected enzymes and microbial systems, can allow its exploitation for the production of functional additives and supplements rich in antioxidant peptides, to be used in new food formulas for human consumption [18]. Mosquera et al. [23] encapsulated a collagen peptidic fraction obtained from sea bream scales subjected to enzymatic hydrolysis in nanoliposomes selleck chemical made of partially purified phosphatidylcholine obtained from industrial soy by-product. Authors as Ahn et al. (2012) [33], and Ahn

et al. (2014) [34] produced bioactive peptides from pectoral fin protein from salmon processing byproduct by enzymatic hydrolysis, and the produced hydrolysate exhibited antioxidant activity. Centenaro et al. [32] report that meat and fish provide valuable sources of protein for many populations around the world; furthermore, meat and fish proteins offer huge potential as novel sources of bioactive peptides displaying antioxidant effects. Different authors 22, 35, 36 and 37 affirm that fish proteins have properties that are advantageous in the preparation of films, such as the ability to form networks, plasticity and elasticity. Edible covers with nanoclays can extend the shelf life and improve the quality of fruits Selleckchem Abiraterone by providing barriers to mass transfer, improving integrity or handling and/or the functional loads such as antimicrobial agents

and antioxidants. El-Halal et al. (2014) [36] stated that proteins have been used extensively because of their relative abundance, nutritional qualities and film-forming ability with a good structural integrity and mechanical properties. It was interesting to investigate the effects of protein isolate and glycerol concentration and pH on the properties of protein films obtained from Whitemouth croaker (Micropogonias furnieri) residues [35]. It is also important to consider that the formation of the films involves a complex series of chemical reactions; these are influenced by experimental conditions such as protein concentration, heating temperature and the addition of a plasticizer [30].
