本研究中描述的最小精炼方法使得用Ca(OH)(2)、MgO和Na2SiO3作为NaOH的替代品来中和粗菜籽油成为可能。经柠檬酸脱胶后，原油中约98%的磷被脱除。经Ca(OH)(2)最小中和后，游离脂肪酸含量由0.50%降至0.03%。其他质量参数，如过氧化值、茴香胺值和叶绿素含量，经过传统中和和最小中和后均在工业可接受水平内。使用三烷基二氧化硅和镁醇R60，可以去除热水洗涤步骤，减少残余皂液的残留量
The minimal refining method described in the present study made it possible to neutralize crude canola oil with Ca(OH)(2), MgO, and Na2SiO3 as alternatives to NaOH. After citric acid degumming, about 98 % of the phosphorous content was removed from crude oil. The free fatty acid content after minimal neutralization with Ca(OH)(2) decreased from 0.50 to 0.03 %. Other quality parameters, such as peroxide value, anisidine value, and chlorophyll content, after traditional and minimal neutralization were within industrial acceptable levels. The use of Trisyl silica and Magnesol R60 made it feasible to remove the hot-water washing step and decreased the amount of residual soap to
