研究了一种以碳酸氢钠为基础的介质（pH 9.5）对菜籽油体进行水处理的方法。研究了研磨过程中种子与介质质量的比例以及所用介质的摩尔浓度对油体完整性、纯度和储存稳定性的影响。以1：7（w/w）的比例在溶液中研磨种子显著改善了油体悬浮液的质量，使其尺寸更符合体内观察到的尺寸（平均D-4，D-3为1.19 μ m）。回收的油体的纯度和组成取决于所用介质的摩尔浓度;在研磨和洗涤步骤中使用碳酸氢钠溶液（pH 9.5，0.1M）产生的油体制剂具有与用9 M尿素洗涤粗制剂所产生的油体制剂相同的纯度。所得乳液在一个月的储存期内具有改进的物理稳定性。
An aqueous process for the recovery of oil bodies from rapeseed using sodium bicarbonate-based soaking and grinding media (pH 9.5) was investigated. The effect of the ratio between seed and mass of media during grinding and molarity of the medium used on oil body integrity, purity and storage stability have been studied. The grinding of seeds in solution at a ratio of 1:7 (w/w) significantly improved the quality of oil body suspension to a size more in-line with that seen in vivo (average D-4,D-3 of 1.19 mu m). The purity and the composition of the recovered oil bodies depends on the molarity of medium used; the use of a sodium bicarbonate solution (pH 9.5, 0.1 M) in the grinding and washing steps produced oil body preparations with the same purity as that resulting from washing a crude preparation with 9 M urea. The resultant emulsion had improved physical stability over a storage period of one month.
