摘要
研究了三种提取方法对核桃油得率、理化性能、总黄酮含量、不饱和脂肪酸含量的影响。结果表明:索氏抽提核桃油得率高(66.46%);超临界CO2萃取核桃油酸值(0.962mg/g)、过氧化值(0.912mmol/kg)低,总黄酮含量(35.63mg/100g)、不饱和脂肪酸含量高(95.13%),油脂色泽浅,符合人们对植物油口感的要求。
Walnut oil obtained by three extraction methods was researched on the yield, physicochemical properties, content of total flavone and unsaturated fatty acid. The results showed that the oil of soxhlet has the higher yield （66.46 %）, the oil of SCF CO2 has the lower acid value （0.962 mg/g）and peroxide value（0.912 mmol/kg）, the higher content of total flavone （35.63 mg/100 g） and unsaturated fatty acid （95.13 % ）, the lighter color. Walnut oil obtained by SCF CO2 is fit for the modem requirement.
