Title : Prebiotic activity of enzymatically extracted soluble dietary fibres from oil seed meals
Abstract:
Prebiotics stimulates the growth of probiotic beneficial bacteria and fungi. Prebiotics can be degraded by intestinal microbial organisms. Dietary fibre (DF), stimulate the growth of probiotics and can be classified as Soluble Dietary Fibre (SDF) and Insoluble Dietary Fibre (IDF). DF is one such nutrient that is abundantly available in the de-oiled meals. The present study deals with isolation of soluble fractions of DF from de-oiled meals, by enzymatic extraction. This is followed by the evaluation of its various anti-oxidative and functional properties to estimate its applicability as a nutraceutical and also for incorporation in functional food.
The oilseeds? mustard, sesame, rice-bran and linseed were collected from Kolkata, West Bengal, India and after oil-production, the de-oiled cakes generated from the aforementioned oilseeds were procured from Vinayak Oil and Fats Private Limited, Howrah, West Bengal. SDF was extracted according to the AOAC enzymatic-gravimetric method. The characterisations of the enzymatically extracted SDF was done. The biological activities of the enzymatically extracted SDF were evaluated. Water soluble M-SDF, S-SDF, RB-SDF and LS-SDF were enzymatically generated that showed some non-nutritional functions due to the polyphenols masked in them. Fibre acquired from food industry wastages are a better alternative to and can partially replace flour, sugar, fat, as they are non-caloric, inexpensive, bulking agents with auxiliary health advantages.
