The present study deals with the production of DAG oils by enzymatic process and their utilisation in different soy spreads by substituting TAG oils for health beneficial effects. The proximate composition, physical properties (colour, hardness, viscosity) and microbial analysis of the different DAG based spreads revealed good acceptability. The spreads were enriched with appreciable amino acid profile of soy seed meal along with health beneficial antioxidants like oryzanol, lignans, tocopherols from the Rice bran DAG and sesame DAG rich oils used. For the feeding experiment, rats were divided into four groups, each consisting of five rats. TAG based soy spreads were taken as control while making DAG based spreads as experimental group. Food efficiency ratio, plasma lipid profile, plasma bilirubin content, plasma glucose level, liver and brain lipid profile and antioxidant activity were measured by using standard procedures. The feeding trial indicates maximum health beneficial effect of RBDG based spread fed rats group as followed by SDG based spread. The results indicated positive lipid and cholesterol lowering effect for DAG enriched spreads as compared to TAG enriched spreads and thus making it suitable for application as nutraceuticals in food products as replacement of TAG oils to combat obesity and dependent diseases.
