Application of beta zeolite as multitoxin binder in animal feed

Abstract

The present invention relates to the application of beta zeolite in animal feed as a toxin binder. The beta zeolites, which contain 12 membered ring systems with Bronsted and Lewis acidic sites, have high binding efficacy against common toxins present in animal feed. This study aimed to evaluate the binding efficacy of The disclosed H beta zeolite (HBZ) has high binding efficiecy against major mycotoxins such as aflatoxin B1, ochratoxin A (OTA), zearalenone, mycophenolic acid, cyclopiazonic acid, Fumonisin B1, T-2 and patulin.

We claim: 
     
         1 . A toxin binder comprising microporous zeolite materials having 12 membered ring systems. 
     
     
         2 . The toxin binder of  claim 1 , comprising either a NH 4 + or H+ form of beta zeolite. 
     
     
         3 . The toxin binder of  claim 2 , wherein the beta zeolites have pore sizes in the range of 1-15 Å but preferably about 5 Å. 
     
     
         4 . The toxin binder of  claim 2  wherein the beta zeolites have a Si/Al ratio in the range between 10-50, preferably around 25. 
     
     
         5 . The toxin binder of  claim 2 , wherein the beta zeolites having Lewis and Bronsted acidic sites at the surface and inside the pores. 
     
     
         6 . The toxin binder of  claim 1  for use as multitoxin binders in animal feed supplements. 
     
     
         7 . The toxin binder of  claim 1 , for binding a mycotoxin, wherein the mycotoxin is selected from the group consisting of aflatoxin B1, ochratoxin A, zearalenone, mycophenolic acid, cyclopiazonic acid, fumonisin B1, T-2 and patulin and also extends to toxic secondary metabolites produced by fungus, bacterial exotoxins, bacterial endotoxins, ergot alkaloids and pesticides.
