Green recovery of antioxidants from “Cẩm” purple rice bran by microwave-assisted extraction: Optimization and evaluation of its antioxidant and anti-diabetic properties [pdf]

Rice is one of the most important staple foods around the world.Globally, 757 million tons of rice and paddy were produced in 2020 (Park et al., 2023).In Vietnam, various rice varieties are cultivated and produced annually.However, rice production generates a large amount of waste, which could be used to create value-added products (Van Tai et al., 2023).One waste product from rice production is rice bran.With a potential global market of 29.3 million tons per year, rice bran is a significant byproduct of the rice milling industry.Because of its rich nutrient content, low cost, easy availability, high antioxidant capacity, and promising effects against numerous metabolic disorders, it is attracting the attention of researchers (Sohail et al., 2017).Recent research has shown that rice bran contains various nutrients as well as antioxidant compounds (Huang and Lai, 2016).The
