Enrichment of linoleic acid from passion fruit seeds by crystallization aid assisted urea encapsulation method
Linoleic acid was enriched by tartaric acid-assisted urea adduction fractionation from passion fruit seed oil.Single factor and orthogonal experiments were used to study the effects of the ratio of tartaric acid to urea,urea to ethanol,fatty acid to urea,adduction temperature,and adduction time on the purity and yield of linoleic acid during urea inclusion.When the process conditions are tartaric acid to urea ratio of 1:5(g/g),mixed fatty acids to urea ratio of 1:2(g/g),urea to ethanol ratio of 1:7(g/g),the encapsulation time of 12 h,and the encapsulation temperature of 5℃,the linoleic acid content of passion fruit seed oil can be increased from 68.13%to 96.61%,with a yield of 78.00%.
