米糠油脱酸工艺研究进展

米糠油是一种营养价值丰富的植物油，其富含多种生理活性物质。米糠中富含高活性脂肪酶，这使得米糠毛油的酸价很高，因此采用满足高脱酸率以及高生理活性物质保留率的脱酸工艺显得尤为重要。不同的脱酸工艺对米糠油的品质油具有显著性影响。本文详细的介绍了近些年国内外米糠油现有的脱酸工艺，对蒸馏法脱酸、膜分离技术脱酸、超声波辅助精炼技术脱酸、溶剂萃取脱酸、化学碱炼脱酸、酶催化酯化脱酸等方法进行归纳总结，旨在为米糠油脱酸的研究提供依据。

A review of advanced deacidification progressing technology of rice bran oil

Rice bran oil, in rich with many kinds of active compounds, is a valuable nutrition of vegetable oil. The high-acid value of crude rice bran oil is due to the amount of lipase originated from rice bran during the extraction oil processing. Therefore, it is of particular importance to meet the high deacidification efficiency demand in oil-refined industries as well as the high retention of active substances in rice bran oil products. Different deacidification processes significantly affect the quality of rice bran oil. In this text, the deacidification processes such as distillation deacidification, membrane separation deacidification, ultrasonic assisted-refined deacidification, solvent-extraction deacidification, chemical alkali-refined deacidification and enzymatic catalyzed esterification deacidification for rice bran oil were introduce. It aimed to provide a scientific reference for the deacidification processing of rice bran oil in the future of research.
