Production of Structured Triacylglycerols from Perilla Seed Oil and Tripalmitin Catalyzed by Lipozyme RM IM
Abstract:
Unsaturated free fatty acids (UFFAs), which are rich in α-linolenic and omega-3 fatty acids, were obtained by alkali hydrolysis and urea complexation methods from perilla seed oil and used as the acyl donor to produce structured triacylglycerols (STAGs) catalyzed by Lipozyme RM IM. The results indicated that the content of α-linolenic acid was increased to 73.16 % after urea complexation methods. The highest incorporation rate of α-linolenic acid was 58.78 %, which were achieved under the optimum conditions: a molar mass ratio of tripalmitin to UFFAs of 1:12, a reaction time of 48 h and a temperature of 60 °C.
