Zeolites and Mycotoxins? Do you mean for human consumption?

[Guest guest]

Barb/Jill-

What is " Zeolite " ?

Is it some kind of clay or earth-based mineral?

There isn't much on zeolite and mycotoxins on the huge medical database Pubmed.

Just a very few documents like this:

This is not about HUMAN consumption, just about the interface between

the two materials..

IMO, people desperate to get better might want to ask their doctor if

they could try activated charcoal if they can't get cholestyramine.

Adsorption of zearalenone (ZEN), ochratoxin A (OCHRA) and

aflatoxin B1 (AFB1) on natural zeolite, clinoptilolite, modified with

different amounts of octadecyldimethylbenzyl ammonium (ODMBA) ions was

investigated. Results showed that adsorption of hydrophobic ionizable

ZEN on unmodified zeolite tuff was very low and that adsorption on

organozeolites increased with increasing hydrophobicity of the

zeolitic surface. The adsorption was independent of the form of ZEN in

solution and the solution pH, indicating that hydrophobic interactions

with ODMBA are responsible for ZEN adsorption. Adsorption of low polar

ionizable OCHRA on organozeolites also increased with increasing

hydrophobicity of the zeolitic surface, however, OCHRA showed moderate

adsorption on unmodified zeolitic tuff at pH 3. OCHRA adsorption on

unmodified zeolite as well as on lower surface coverage of

organozeolite was dependent on the form of OCHRA in solution; there

was a decrease of adsorption at high pH, where OCHRA is in the anionic

form. It indicated that at acidic pH, low surface coverage allows some

combination of hydrophobic interaction with ODMBA and interactions

with the surface of the zeolite. At higher surface coverage, the OCHRA

adsorption was higher and practically independent of pH, indicating

that the hydrophobic interactions of OCHRA with ODMBA are responsible

for its adsorption. Nonionizable low polar AFB1 had a high affinity

for the unmodified zeolitic tuff and the adsorption of AFB1 was

greatly reduced for organozeolites, indicating that AFB1 does not have

high tendency for hydrophobic interactions with ODMBA. pH dependence

of AFB1 adsorption, while AFB1 has the same form at all pHs,

demonstrated that the surface modification of the zeolite depends on

pH and that these modifications have influence on its adsorption. The

calculated dipole moments of neutral mycotoxin molecules: AFB1-9.5D,

OCHRA-6.9D and ZEN-2.2D are in qualitative agreement with adsorption

experimental data.
