超临界CO2状态下制备高度乙酰化大豆磷脂工艺
Preparation of Highly Acetylated Soybean Phosphatide Using Supercritical CO2
摘要
Abstract
In the present study,supercritical CO2was used to prepare highly acetylated soybean phosphatide from transparent concentrated soybean phospholipid.The optimal preparation conditions were determined as follows： acetic anhydride amount 2.8%,reaction temperature 65 ℃,reaction time 35 min,and reaction pH 7.3.Under these reaction conditions,the acylation rate of soybean phosphatide was 93.2%.Compared with the preparation process at regular state,the amount of acetic anhydride and reaction time were decreased by 0.2% and 5 min,respectively,and the acylation rate was increased by 1.4%.Moreover,an improvement in emulsifying capacity and dispersion capacity was achieved over concentrated soybean phospholipid.关键词
