Study on enrichment of polyunsaturated fatty acids in sweet almond oil by molecular distillation
摘要
Abstract
The enrichment conditions of polyunsaturated acids from sweet almond oil by molecular distillation was researched.After ethyl esterified,the main factors,including distillation temperature,scraper speed,feed rate and operating pressure,influenced the result of molecular distillation were analyzed by single factor tests.Based on the result of single factor tests,Box-Behnken response surface was designed to optimize the distillation parameters combined with the equipment,the optimum parameters were：distillation temperature 109℃,the scraper speed 350r/min,operating pressure 3Pa,in this condition,the content of polyunsaturated fatty acids was 93.883%.The result indicated that the enrichment of polyunsaturated fatty acids in sweet almond oil by molecular distillation was feasible.关键词
