Recent updates on bioaccessibility of phytonutrients

ConclusionsFood matrix, processing and preservation methods have major influence on the bioaccessibility of phytonutrients. Cooking, frying and pasteurization increased the bioaccessibility of polyphenols and carotenoids in fruits and vegetables. Dehydration can be a good technique to enhance the bioaccessibility of carotenoids. Freezing showed contradictory response on bioaccessibilty as it increased bioaccessibility of phytonutrients in some fruits and decreased in others. To achieve maximum bioaccessibility of carotenoids, thermal treatment along with addition of oil is the best; to enhance ascorbic acid and polyphenols bioaccessibility thermal treatment is the best and for enhanced bioaccessibility of mineral and tocopherols high pressure-processing is most suitable.
