Quinoa is known to be a rich source of nutrients and bioactive components. Quinoa bran, used mainly as animal feed in processing by-products, is also a potential source of bioactive ingredients being conducive to human health. The importance of nutrition and function of quinoa seed has been discussed in many studies, but the bioactive properties of quinoa bran often are overlooked. This review systemically summarized the progress in bioactive components, extraction, and functional investigations of quinoa bran. It suggests that chemically assisted electronic fractionation could be used to extract albumin from quinoa bran. Ultrasound-assisted extraction method is a very useful method for extracting phenolic acids, triterpene saponins, and flavonoids from quinoa bran. Based on in vitro and in vivo studies for biological activities, quinoa bran extract exhibits a wide range of beneficial properties, including anti-oxidant, anti-diabetes, anti-inflammation, anti-bacterial and anti-cancer functions. However, human experiments and action mechanisms need to investigate. Further exploring quinoa bran will promote its applications in functional foods, pharmaceuticals, and poultry feed in the future.
藜麦是一种营养丰富且富含生物活性成分的来源。藜麦麸皮主要作为加工副产品用作动物饲料，也是一种有利于人类健康的生物活性成分潜在来源。许多研究都讨论了藜麦种子的营养和功能的重要性，但藜麦麸皮的生物活性特性常常被忽视。本综述系统总结了藜麦麸皮生物活性成分、提取及功能研究方面的进展。研究表明，化学辅助电子分级分离法可用于从藜麦麸皮中提取白蛋白。超声辅助提取法是从藜麦麸皮中提取酚酸、三萜皂苷和黄酮类化合物的一种非常有用的方法。基于生物活性的体外和体内研究，藜麦麸皮提取物具有广泛的有益特性，包括抗氧化、抗糖尿病、抗炎、抗菌和抗癌功能。然而，人体实验和作用机制仍需研究。进一步探索藜麦麸皮将促进其未来在功能性食品、药品和家禽饲料中的应用。
