本研究的目的是探讨米糠半纤维素体外清除胆固醇和胆汁酸的可能性。本文论证了米糠半纤维素A(RBHA)、米糠半纤维素B(RBHB)和米糠半纤维素C(RBHC)具有结合胆固醇和胆汁酸的潜力。结合的胆固醇和胆汁酸的数量因米糠纤维的不同而不同。从研究结果可以推断，RBHB具有最高的胆固醇结合能力，其次是RBHC和RBHA。胆固醇和胆汁酸与米糠不溶性膳食纤维(RBDF)和米糠纤维素的结合力很差。米糠木素结合胆固醇和胆汁酸的活性最低。这证实了脱脂米皮制备RBHB在食品应用，特别是在开发功能食品方面具有很大的潜力。
The objective of this study was to investigate the possibility of using hemicellulose from rice bran to scavenge cholesterol and bile acid in vitro study. This paper demonstrates that rice bran hemicellulose A (RBHA), rice bran hemicellulose B (RBHB) and rice bran hemicellulose C (RBHC) have the potential for binding cholesterol and bile acid. The quantity of cholesterol and bile acid bound varies from one rice bran fibre to another. As it can be inferred from the results of the study, RBHB was characterized by the highest capacity for cholesterol binding, followed by RBHC and RBHA. Binding of cholesterol and bile acid to rice bran insoluble dietary fibre (RBDF) and cellulose from rice bran was found to be poor. Lignin from rice bran was the least active fraction for binding cholesterol and bile acid. This confirms that the RBHB preparation from defatted rice bran has great potential in food applications, especially in the development of functional foods.
