低能耗菜籽双液相萃取技术

Low Energy-Consuptin Technique of Two-phase Extraction Process of Rapeseed

采用少量适当的助剂，处理菜籽双液相萃取加工时得到的甲醇相母液，可使母液不经提纯，直接大比例地和新鲜甲醇相一起继续用以处理菜籽。母液比例可占处理菜籽所需甲醇相总量的３／４ 以上，从而可大大降低过程能耗。所得成品粕品质不变，色浅、味淡、酥松、适口性好、蛋白质含量高，硫甙含量远低于国家一级饲料标准。

The mother liquid of methanol phase obtained from rapeseed two-phase extraction process can be directly reused in large amounts to process rapeseed again together with some fresh methanol phase,so long as it is treated with a litter of proper additives in advance.The ratio of the reused mother liquid may be more than 3/4 of the total amount of the methanol phase needed for processing rapeseed,so the energy-consuming can be decreased tremendously.The meal obtained by use of the reused mother liquid keeps the quality as good as those obtained by use of totally fresh methanol phase with light color,weak taste,crispness,good palatability,high protein content,and a low level of glucosinolates much more less than that stipulated by the state for the first grade fodder.
