Extraction of Anthocyanins from Red Amaranth and Their Antioxidant Activities in Vitro
Journal: Architecture Engineering and Science DOI: 10.32629/aes.v5i1.1849
Abstract
Amaranth is rich in anthocyanins and has significant antioxidant activity. This paper reviewed the content, extraction methods and antioxidant mechanism of anthocyanins in amaranth. it was found that amaranth not only has a good price, but also has a strong scavenging capacity for superoxide free radicals, DPPH free radicals and hydroxyl free radicals, showing potential medical value. However, the current extraction methods and conditions still need to be further studied and optimized to improve the extraction rate and purity of anthocyanins in amaranth. Therefore, it is suggested that future research should focus on the impact of different extraction methods on extraction efficiency and quality, and further compare the content, cost and quality of anthocyanins in amaranth with those commonly used today, so as to promote the sustainable development of food industry and drug development.
