Recent
studies point out that the use of Phytase NSP Blend could
have a significant effect on the absorption of divalent cations such
as calcium, magnesium and iron. (Phytic acid forms insoluble
complexes with cations). By virtue of its chemical nature the
negatively charged phytie acid readily hinds to positively charged
molecules such as cations and also proteins. Phytic acid is often
classified as an "anti-nutritional factor." Plant phytates
(phytic acid) is found in many plants such as corn, corn
by-products, legumes, soybeans and cereal grains.
By
utilizing phytase in a digestive preparation it eliminates the
possibility of insoluble
complexes
being formed and thus increases the adsorption of the cations
previously mentioned.
It
also hydrolyzes the bound phosphorus groups, which in turn
are absorbed along with the
Calcium,
Iron, Magnesium and Zinc.
The
purpose of the addition of beta glucanase and hemicellulase
is the fact that the cereal grains mentioned above also contain a
high level of non-soluble polysaccharides (NSP). The NSP is mainly
in the form of beta glucans, hemicellulose and arabinoxylans. The
highly viscous polysaccharides bind to digestive enzymes and impair
diffusion to their substrates. The anti-nutritive effect of NSP in
cereals results in a depression in the digestibility of all
nutrients, Therefore, a supplement blend of phytase, hemicellulase
and beta glucanase will have a significant effect on increased
digestion.
