| Abstract:For investigating the mechanisms of carbohydrase treatment and alkaline extraction during aqueous enzymatic extraction of rapeseed oil from wet milled rapeseed,the changes of rapeseed cell ultrastracture during enzyme hydrolysis were observed using SEM and the properties of emulsions in different PH conditions were studied.The results showed that the complex enzyme(mainly pectinase) could destroy rapeseed cell wall effectively and thus released cell contents.The amount of protein bound to the oil droplets in emulsions was less at alkaline,pH,which was possibly in favor of the proteinase hydrolysis the aggregation of oil droplets. |
