Description An enzymatic process was developed for the preparation of a nutritionally enriched 1,3-diacylglycerol(DAG)-
rich oil from a blend of refined sunflower and rice bran oils. The process involves hydrolysis of vegetable oil
blend using Candida cylindracea followed by esterification with glycerol using Lipozyme RM1M. The resultant
DAG-rich oil contains 84% of DAG (66% of 1,3-DAG, 18% of 1,2-DAG) and 16% of triacylglycerol (TAG) along
with micro nutrients like γ-oryzanol, tocotrienols, tocopherols and phytosterols. Nutritional studies of the DAGrich
oil were conducted in Wistar rats and compared with sunflower oil (SFO). The calorific value of the DAGrich
oil was estimated to be 6.45 Kcals/g as against 9.25 Kcals/g for SFO. The serum and liver cholesterol and
TAG levels in rats fed with 1,3-DAG-rich oil were found to be significantly reduced as compared to rats fed diet
containing SFO. We conclude that 1,3-DAG-rich oil is a low calorie fat and exhibits hypolipidemic effects.
