摘要
对金樱子籽油进行提取和精炼,考察了籽油的理化性质,并用气质联用仪对其脂肪酸组成和含量进行测定。结果表明,金樱子籽油的出油率为5.24%;酸价为0.36 mgKOH/g,过氧化值为46.10 mmol/kg,碘值为160.90 gI2/100 g,皂化值为193.76 mgKOH/g;金樱子籽油中检出5种脂肪酸,其中不饱和脂肪酸质量分数高达86.10%,亚油酸和α-亚麻酸分别为43.99%和42.11%;饱和脂肪酸占13.90%,由棕榈酸、硬脂酸和花生酸所组成。金樱子籽油的不饱和脂肪酸含量较高,是一种值得开发利用的营养保健油源。
The extraction and refinement of rosa laevigata＇s seed oil investigates the physicochemical properties of seed oil. The ingredients and contents of fatty acids in the seed oil are determined with GC - MS. The result shows that the oil yield of rosa laevigata＇s seed oil is 5.24% ; the acid value is 0.36 mgKOH/g; the peroxide value is 46.10 mmol/kg ;the iodine value is 160.90 gl2/100 g; and the saponification value is 193.76 mgKOH/g. Five fatty acids are identified in the rasa laevigata＇s seed oil. The content of unsaturated fatty acid is 86.10% which includes 43.99% linoleic acid and 42.11% α -linolenic acid. But the saturated fatty acid is 13.90% which is composed of palmitic acid, stearic acid and arachidic acid. The seed oil has plentiful unsaturated fatty acids and it is a potential source for nutritional and healthy functions.
