What is the main function of montmorillonite?

Montmorillonite function

1. Mycotoxin adsorption function

MMT has an adsorption effect on mycotoxins, which is mainly through surface adsorption, electrostatic interaction and
and intermolecular forces to adsorb the hydroxyl group, amino group and part of mycotoxin structure can be extremely
chemical group. The research found that MMT has a better effect on aflatoxin B1 (AFB1).
The adsorption and detoxification effect of AFB1 can effectively reduce the absorption of AFB1 by animals and resist the effect of AFB1 on
Animal toxicity, reduce animal acute poisoning mortality, improve animal production performance.
In addition, the researchers also found that MMT has good adsorption to fumonisin and T-2 toxin
effect. The adsorption effect of MMT on mycotoxins is also influenced by the main elements in its structure. like
The adsorption rate of AFB1 and T-2 toxins was higher for sodium-based MMT than for calcium-based MMT.

2. Antibacterial function

Natural MMT has no antibacterial and bactericidal functions, only adsorption, but exchange has antibacterial
The metal ions or groups acting on it can have the corresponding antibacterial and bactericidal functions. Since MMT sucks
After the water expands, the negatively charged plate surface connects with the positively charged edge to form a “gel—
“sol-gel” thixotropic “carriage” suspension, this “carriage” structure can absorb bacteria, and then excreted with intestinal peristalsis. MMT modified by antibacterial ions can absorb bacteria
Bacteria with negative charges tend to increase the permeability of the bacterial cell membrane and significantly release intracellular enzymes.
Inhibits the TCA pathway of bacterial respiratory metabolism, and exerts antibacterial and bactericidal functions. In addition, the research
It was found that dinitramide-MMT compound preparation and MMT-B.subtilis compound were effective against coccidia and
Intestinal Escherichia coli and Staphylococcus aureus produced better inhibitory effects.

3. Heavy metal adsorption function

Excessive heavy metal content in feed has adverse effects on the growth and health of livestock and poultry. MMT utilizes its
The properties of cation exchange, adsorption and hydration swelling have certain influence on heavy metals in diet.
Adsorption, so as to alleviate its harm to animals. Water is an important nutrient for livestock and poultry.
Studies have found that MMT can effectively adsorb heavy metals in water and prevent heavy metal pollution in water.
In addition, adding bentonite to high-copper diets can alleviate the incidence and symptoms of copper poisoning.

4. Adsorption of other substances

MMT not only adsorbs toxic and harmful substances, but also absorbs some nutrients, which has a negative impact on dietary nutrition.
adverse effects, while the modification of MMT can reduce the adsorption of nutrients. MMT and
MMT modified by quaternary ammonium salts has certain adsorption for lysine and vitamin B2, but the modified
The adsorption capacity of MMT to lysine and vitamin B2 is smaller than that of MMT, while the desorption rate is larger than that of MMT.
