A comparative study was done on the production of different medium chain fatty acid (MCFA) rich mustard oil using a stirred tank batchreactor (STBR) and packed bed bio reactor (PBBR) using three commercially available immobilised lipases viz. Thermomyces lanuginosus, Candida antarctica and Rhizomucor meihe. Three different MCFAs capric, caprylic and lauric acids were incorporated in the mustard oil. Reaction parameters, such as substrate molar ratio, reaction temperature and enzyme concentration were standardized in the STBR and maintained in the PBBR. To provide equal time of residence between the substrate and enzyme in both the reactors for the same amount of substrates, the substrate flow rate in the PBBR was maintainedat 0.27 ml/min. Gas liquid chromatography was used to monitor the incorporation of MCFA in mustard oil. The study showed that the PBBR was more efficient than the STBR in the synthesis of structured lipids with less migration of acyl groups. The physico-chemical parameters of the product along with fatty acid composition in all positions and sn-2 positions were also determined.
