Amaranth ( spp.) plant commonly refers to the sustainable food crop for the 21st century. The crop has witnessed significant attention in recent years due to its high nutritional value and agronomic advantages. It is a relatively well-balanced cosmopolitan food that is a protector against chronic diseases. Usually, the antioxidant activities of amaranth are held responsible for its defensive behavior. Antioxidant activity of plants, generally, is attributed to their phytochemical compounds. The current interest, however, lies in hydrolysates and bioactive peptides because of their numerous biological functions, including antioxidant effect. While the importance of bioactive peptides has been progressively recognized, an integrated review of recent studies on the antioxidant ability of amaranth species, especially their hydrolysates and peptides has not been generated. Hence, in this review, we summarize studies focused on the antioxidant capacity of amaranth renewal over the period 2015-2020. It starts with a background and overall image of the amaranth-related published reviews. The current research focusing on in vitro, in vivo, and chemical assays-based antioxidant activity of different amaranth species are addressed. Finally, the last segment includes the latest studies concerning free radical scavenging activity and metal chelation capacity of amaranth protein hydrolysates and bioactive peptides.
苋属植物通常被认为是21世纪的可持续粮食作物。近年来，由于其高营养价值和农艺优势，这种作物受到了广泛关注。它是一种相对营养均衡的世界性食物，对预防慢性病有作用。通常，苋属植物的抗氧化活性是其发挥保护作用的原因。一般来说，植物的抗氧化活性归因于其植物化学化合物。然而，目前人们对水解产物和生物活性肽很感兴趣，因为它们具有多种生物学功能，包括抗氧化作用。虽然生物活性肽的重要性已逐渐得到认可，但尚未对苋属植物，尤其是其水解产物和肽的抗氧化能力的近期研究进行综合综述。因此，在本综述中，我们总结了2015年至2020年期间关于苋属植物抗氧化能力的研究。首先介绍了苋属植物相关已发表综述的背景和总体情况。接着阐述了目前针对不同苋属植物基于体外、体内和化学分析的抗氧化活性的研究。最后一部分包括了关于苋属植物蛋白水解产物和生物活性肽的自由基清除活性和金属螯合能力的最新研究。
