Abstract: In this study, the lipase (from Thermomyces lanuginosa)-catalyzed acidolysis process of rapeseed oil with caprylic acid was investigated to prepare structural lipids using single factor and response surface tests. The results showed that the incorporation rate of caprylic acid reached up to 23.19% at the conditions of the molar ratio between rapeseed oil and caprylic acid of 1:3.57, immobilized lipase addition amount of 10.57%, water addition amount of 5.2%, reaction temperature of 48.6 ℃ and reaction time of 12 h. This investigation will be significance for improving the additional value of rapeseed oil and extending its industry chains.

Key words: rapeseed oil, caprylic acid, acidolysis, structural lipids, response surface methodology
