“…Nutraceuticals can be classified using different approaches. Some of the most common classification methods are based on food sources (dietary fiber, probiotics, prebiotics, polyunsaturated fatty acids, antioxidant vitamins, polyphenols and spices) (Verma & Mishra, 2016); oral bioavailability, which classifies nutraceuticals according to their bioaccessibility, absorption, and transformation characteristics (McClements, Li, & Xiao, 2015); food availability: (a) traditional nutraceuticals including nutrients, herbals, phytochemicals, probiotic microorganisms and nutraceutical enzymes and (b) nontraditional nutraceuticals including fortified and recombinant nutraceuticals (Chanda, Tiwari, Kumar, & Singh, 2019); or biochemical structure (Das et al, 2012). Biochemical nutraceutical categories include phenols, lipids, organic acids and polysaccharides, organosulfurs, phytic acid, phytosterols, and terpenes (Nwanodi, 2017) (Table 1).…”
