Abstract:
Certain anti-nutritional factors (ANFs) interact with proteins and form insoluble complexes hence, decreases bioavailability of proteins. Twenty four different hybrid varieties of pigeon pea [
Cajanus cajan (L.) Millsp.] were analysed for reduction in ANFs on different soaking treatments. Soaking in distilled water and different salt solutions
viz. 1% NaHCO
3, mixed salt solutions (MSS) (1.5% NaHCO
3+0.5% Na
2CO
3+0.75% citric acid) led to a significant (P<0.05) reduction in total phenols, ortho-dihydroxyphenols, tannins and phytates. Phenols and tannins are water soluble and present in seed coat hence, a large reduction observed after simple soaking in distilled water i.e 33.07% and 40.9% respectively. Soaking in distilled water, 1% NaHCO
3 and MSS reduced ortho-dihydroxyphenols by 17.39%, 34.78% and 47.83% whereas phytate by 14.9%, 18.3%, and 21% respectively. Amongst various methods studied, soaking in MSS found to be the most effective in reducing levels of ANFs in pigeon pea hybrids.
