Description
Dandan Gao, Yuxuan Zhang, and Hongxin Ma prepare antioxidant peptides from quinoa protein and test them in ageing mice in a 2026 study. Quinoa is prized as a complete protein, and breaking it into small peptides with digestive enzymes can release fragments that fight oxidative damage linked to ageing.
Six enzymes were tried, and pepsin produced the most active preparation in laboratory assays, with over half its amino acids being essential types. Fed to mice aged artificially with a sugar treatment, the peptides protected liver, kidney, and lung tissue and restored antioxidant enzyme activity in blood and liver. Damage markers fell while the genes and proteins for protective enzymes rose.
