【摘要】 以水酶法提取菜籽油过程中形成的乳状液为研究对象,并以得油率为指标,利用离心并无水乙醚萃取的方法进行破乳,采用正交法对破乳工艺条件进行优化,结果表明,在离心转速9000r/min、离心时间30min、pH 5、无水乙醚加入量70%条件下,乳状液中的油回收率为98.05%。更多还原

【Abstract】 Emulsion formed in the aqueous enzymatic extraction of rapeseed oil was taken as study object,the oil extraction rate as index was investigated,centrifugation and absolute ether extraction were used to demulsificate in aqueous enzymatic extraction of rapeseed oil.Throught orthogonal test optimization,the optimal conditions were found to be: centrifugation speed 9000r/min,centrifugation time 30min,pH 5.0,absolute ether 70%.Under these conditions,the oil extraction rate was 98.05%.更多还原
