Abstract
Oil seeds are an extremely important economically viable food crop. Extraction of oil and oil-bearing materials from oilseeds results in generation of large quantity of residual oil meals worldwide, that sums up to 86.24 million ton approximately. These de-oiled counterparts in spite of high protein, dietary fibre and phytochemical content, receive much less importance. Only a minute proportion is used as manure and animal feed while the major portion is disposed of as wastage and dumped in the open spaces due to a lack of proper resources for handling solid wastes. This necessitates an urgent need for development of a suitable technology for conversion of the seed cake into economically viable products. Our study involves extraction of soluble dietary fibre from the de-oiled seed meals namely mustard and sesame by the enzymatic gravimetric method. Following extraction, the anti-oxidative activities like DPPH Radical scavenging activity, FRAP activity and metal chelating activity were estimated and correlated with their phenolic as well as flavonoid profiles. Functional properties such as solubility, water and oil holding capacity, emulsifying activity, glucose and cholesterol adsorption abilities were also quantified. All the tests were performed using commercial inulin as a control. The extracted soluble dietary fibres demonstrated good anti-oxidative as well as functional properties and exhibited immense potential to be used as a cost-effective functional food ingredient. Bioactive dietary fibre prepared from byproducts of the edible oil industry will facilitate waste reduction and valorization.
