Enzymatic production of fructose fatty acid ester using lipases from C. antarctica and porcine pancreatic
The aim of this work was to produce fructose fatty acid ester by enzymatic esterification of a fatty acid (oleic acid or linoleic acid) with fructose, using lipases (CALB) from Candida antarctica type B and porcine pancreas. The esterification reaction was conducted at 150 rpm and 40 °C during 72 ho...
