| Description |
The investigation aimed at studying the influence of soya proteins on in vitro dialysability of exogenous iron and zinc. Soyabean was processed into various components like soya flour (SF), concentrate (SC) and isolate (SI) and two peptides (<30kDa and >30kDa). The protein contents of SF, SC and SI were 51, 62 and 78g/100g, respectively. Their iron contents ranged between 9.7 and 15.8mg/100g and zinc contents from 3.3 to 6.7mg/100g. Phytic acid contents (mg/100g) of the soya components were SF 339, SC 226, SI 186 and peptides 18-20. In SF, percent dialysable iron and zinc were 12.6 and 50, respectively, this reduced to one-third and one-fifth in SC and SI. Dialysability of exogenously added minerals was found to be significantly lower in all soya protein components. However, the inhibitory effect was less pronounced in peptides. The protein component/matrix effect needs to be investigated to counteract the inhibitory effect of soya on iron dialysability.
