Antinutrients in Oilseed Brassica: Uses and Potential Applications

Rapeseed- mustard is an important oilseed crop in India and worldwide. Rape-Mustard seed complement high oil content of about 35-45%, with a high value protein or meal product after oil extraction. The defaced meal obtained after oil extraction is rich in protein, but it also contains a number of antinutrients like glucosinolates, phytates, phenolics and fibre which limits the use of defaced meal as a source of protein in diet of animals, birds and fish. It also addresses the means of improving the nutritive value of rapeseed mustard meal through seed dehulling, development of low glucosinolate, low-fiber varieties, or application of feed enzymes. Moreover, these antinutrients have various potential applications which can be explored for different uses. As glucosinolates and their breakdown products, isothiocyanates have health protective effects, phytates are known to act as strong chelating agents, sinapic acid contributes to the product's antioxidant activity and dietary fiber may contribute to the reduction in diseases. The present paper reviews antinutritional factors present in oilseed brassica, their effects on animal health and their potential applications.
