Antioxidant peptides obtained by enzymatic hydrolysis

Dear colleagues,

Although vitamins are the nutrients best known for their antioxidant capacity, almost all nutrient groups have molecules with antioxidant capacity. In fact, we can say that the nutrient group with the most powerful antioxidant molecules belongs to the protein group.

For example, among antioxidant proteins we have glutathione peroxidase, a key enzyme for controlling oxidative stress in the body, which acts thanks to another protein in the form of a peptide, glutathione.

Therefore, it is not surprising that peptides obtained from dietary proteins also exhibit significant antioxidant activity, which can have beneficial effects on promoting animal health by helping to reduce inflammation and immunosuppression.

Some characteristics of antioxidant peptides are amino acids (His, Trp, Phe, Pro, Gly, Lys, Ile, and Val) with hydrophobicity, indole/imidazole/pyrrolidine ring, together with steric structure at the C- and N-terminals. Following these guidelines, at NBG we have developed NBG DigestaPro and NBG EnteroPro through specific enzymatic hydrolysis and ultrafiltration. These are highly digestible fish hydrolysates that help improve animal health and performance.

Finally, we have attached an article reviewing the structural characteristics of peptides and their antioxidant activities.
