Re: Re: soaking does not reduce phytic acid ?

[Guest guest]

It is known that certain methods can reduce phytates in grains/legumes,

including soaking in an acidic medium (1). Perhaps the small reduction in

phytates was the result of improper soaking methods (e.g., not at room

temperature or not using an acidic medium). Not having the whole paper in

front of me, its difficult to say.

availability of iron and zinc. Adv Exp Med Biol, 1991, 289: 499-508; ( U

germination and fermentation. In: Nutrient Availability: Chemical and

Biological Aspects. Southgate DAT, IT, Fenwick GR, eds. (Cambridge

All the best,
