Rancimat法测定3种坚果油脂氧化稳定性的条件研究
Influence of the parameters of the rancimat test on the determination of the oxidative stability of three kinds of nut oils
摘要
Abstract
The operational parameters such as temperature ,airflow and sample weight of the Rancimat method were conducted to determine their effects on the oxidative stability index (OSI) of three kinds of nut oils (walnut oil ,almond oils and sweet apricot kernel oil) .To this end ,single factor experiment and Box-Behnken experiment were investigated .The exper-imental data were fitted to a complete quadratic model and an ANOVA analysis was per-formed ,which concluded that only temperature was significant (p<0 .01) .By means of the quadratic model and using response surface methodology in order to minimize the OSI ,the optimal conditions for the three parameters of the Rancimat method were as following :first-ly ,for the walnut oil ,temperature 120 ℃ ,airflow 18 .14 L/h ,sample weight 3 .00 g ;second-ly ,for the almond oil ,temperature 120 ℃ ,airflow 13 .48 L/h ,sample weight 3 .93 g ;finally , for the sweet apricot kernel oil ,temperature 120 ℃ ,airflow 12 .18 L/h ,sample weight 4 .20 g respectively .关键词
