Rice bran oil deacidification by immobilized Aspergillus Niger lipase catalyzed esterification with D-isoascorbic acid

Synthesis of lipase-hydrogel microspheres and their application in deacidification of high-acid rice bran oil

“…RBO extracted from rice bran typically contains 10–40% free fatty acids and the high-acid value of RBO reduces the quality of RBO and increases the difficulty of refining. 31 Therefore, it was of great significance to study the deacidification process of HRBO. In this study, PHAM2, PHAM3 and PHAM4 were immersed in lipase phosphate buffer (40 mg mL −1 , pH 7.4) for 3 h respectively to obtain L-PHAM2, L-PHAM3 and L-PHAM4.…”

“…At the same time, it has excellent biocompatibility and can better meet the needs of industrial mass production. [28][29][30][31][32] In particular, the interaction between hydrogel microspheres and enzymes enhances the tolerance and operational stability of enzymes to harsh environments. [33][34][35] In addition, the size of the hydrogel microspheres can be controlled, and its porous structure can greatly increase the specific surface area of the hydrogel, which is conducive to improving the enzymatic load and substrate transfer efficiency.…”
