摘要

从木聚糖酶、淀粉酶、纤维素酶、中性蛋白酶、复合植物水解酶和果胶酶中筛选出了提取山茱萸果实油脂的最佳酶。结果表明:纤维素酶的提取率最高，为65.29%;复合植物水解酶的提取率次之，为64.05%;木聚糖酶的提取率最低，为54.47%;通过单因素试验，得到纤维素酶的最佳提取条件为:pH 5.8，料液比1∶3，酶用量2.5%，反应温度40℃，反应时间4 h，在此条件下，提取率可达76.64%。

Aqueous enzymatic extraction of Cornus wilsoniana fruit oil

The optimum enzyme of extracting oil from Cornus wilsoniana fruit was selected from xylanase,amylase,cellulase,neutral protease,composite plant hydrolytic enzymes and pectinase.The results showed that the oil extraction rate(65.29%) with cellulase was the highest among the six kinds of enzyme,and the oil exraction rate(64.05%) with composite plant hydrolytic enzymes was the second,the lowest oil extraction rate was 54.47% only by xylanase.By single factor test,the optimum conditions with cellulase was obtained as follows: pH 5.8,solid-liquid ratio 1∶3,enzyme dosage 2.5%,reaction temperature 40 ℃,reaction time 4 h.Under these conditions,the oil extraction rate reached 76.64%.
