Special Issue Information

Dear Colleagues,

New natural antioxidant peptides are of great interest in the food industry. They can be used as additives to avoid food oxidation, preserve food quality, prolong shelf life and reduce losses in food production. Still, in recent years, the production of functional foods, with antioxidant potential, has been highlighted as a way of promoting well-being and health. Peptides are formed by digestion, fermentation or enzymatic activity of proteins, generating shorter sequences with new properties, absent in the precursor protein.  The diversity of food proteins existing in nature from plants, animals or fungi provides a wide possibility for the discovery/production of new peptides with pharmacological application. New technology strategies are being studied to generate better antioxidant sequence and physiological activity, including in vitro and in vivo assays, clinical trials and bioinformatics. The biological significance of this activity has been less explored. Studies in cell culture and animal models are of pivotal importance to better explore the resistance of peptides in the digestive tract, the bioavailability and the mechanisms of action at the cellular level. Bioactive peptides may be a promising strategy for application in food as a natural antioxidant additive and exert bioactivity, reducing the risk of oxidative chronic disease.

Sunflower (Helianthus annuus L.) and African palm kernel (Elaeis guineensis Jacq.) are among the most cultivated in the world regarding oil extraction. The oil industry generates a large amount of meal as a by-product, which can be a source of nutrients and bioactive compounds. However, the physiological effects of bioactive compounds in such matrices are only valid if they remain bioavailable and bioactive after simulated gastrointestinal digestion. This study evaluated the chemical composition and antioxidant and prebiotic potential of de-oiled sunflower (DS) and de-oiled palm kernel (DP) meal after in vitro digestion. The DS sample had the highest protein content and the best chemical score, in which lysine was the limiting amino acid. Digested samples showed increased antioxidant activity, measured by in vitro methods. The digested DS sample showed a better antioxidant effect compared to DP. Moreover, both samples managed to preserve DNA supercoiling in the presence of the oxidizing agent. The insoluble fractions after digestion stimulated the growth of prebiotic bacterium, similar to inulin. In conclusion, simulated gastrointestinal digestion promoted in both matrices an increase in protein bioaccessibility and antioxidant capacity, pointing to a metabolic modulation favorable to the organism.
