摘　　要：米糠脂肪烷醇是天然存在于米糠蜡中,有着调节血脂、抗炎、抗疲劳、提高免疫力等独特生理活性的一类高级脂肪烷醇混合物,属于国家卫健委批准的新型食品原料,十分具有研究价值。该研究对米糠脂肪烷醇的主要组成成分(二十二烷醇、二十四烷醇、二十六烷醇、三十烷醇和三十二烷醇)、生理功能、及物理化学修饰(乳液、微胶囊、纳米颗粒、酯化反应)的研究进展进行综述,并对其不同组分配比和生理功效的关系进行了展望,结果表明,米糠脂肪烷醇的生理功效是高级脂肪烷醇组合综合作用的结果,它是否能发挥稳定效果可能与高级脂肪烷醇混合物的组成成分有关。这为进一步开发这一新型食品原料提供参考依据和研究思路,对充分利用米糠资源结合发展人类大健康产业具有实际意义。Rice bran fatty alcohols are a mixture of higher aliphatic alcohols that exist in rice bran wax.They have unique physiological activities,such as lipid-regulating,anti-inflammatory,and anti-fatigue effects,and immunity enhancement.These alcohols are considered a new type of food ingredient of great research value and are approved by the National Health Commission.In this paper,the main components(behenyl alcohol,tetracosanol,hexacosyl alcohol,triacontanol,dotriacontanol),bioactivities,and physicochemical modifications(emulsion,microencapsulation,nano-particles,esterification)of rice bran fatty alcohols were reviewed.The relationship between its fingerprint and bioactivities is discussed.The combined effect of higher aliphatic alkanols resulted in optimal bioactivity of rice bran fatty alcohol;exerting a stabilizing effect may be related to the fingerprint of the mixture of higher aliphatic alkanols.This study provides a reference for the development of a new food raw material,policosanol,from rice bran wax.There are practical implications for the use of rice bran resources in conjunction with the development of the human health industry.
