    摘要:

    采用多频超声波技术对菜籽油的酶法(磷脂酶A1)脱胶效果及其脱胶后油品质变化展开了相关研究。结果表明,多频超声波作用能有效地提高磷脂酶A1对菜籽油的脱胶效率,大幅度降低脱胶后菜籽油中的含磷量;并且20/50 kHz双频超声处理对菜籽油的脱胶效果最佳。与磷脂酶A1脱胶后菜籽油相比,超声波作用后的脱胶油酸价和过氧化值略有上升(均在国家标准所规定的安全范围内),色泽变浅,脂肪酸组成的数值变化不明显。

    Abstract:

    The effect of multi-frequency ultrasound assisted enzymatic(phospholipase A1) treatment on the degumming efficiency and quality of rapeseed oil was investigated in this study. The results showed that multi-frequency ultrasonic treatment can effectively improve the degumming efficiency of rapeseed oil and also reduce the ultimate phosphorus content in the rapeseed oil. In addition,the 20/50 kHz dual-frequency ultrasonic treatment had the best degumming efficiency of rapeseed oil. Compared with the rapeseed oil after degumming by phospholipase A1,the acid value and peroxide value of degummed rapeseed oil after ultrasonic treatment increased slightly,but they were all within the safe range stipulated by the national standard. Moreover,the color of degummed oil became lighter,and the change in the value of fatty acid composition was not obvious.
