Abstract

An effective method to control aflatoxin produced by toxic strains of Aspergillus parasiticus fungi is disclosed. An effective amount of Beta-ionone is applied to said fungi to inhibit the growth and sporulation of the fungi and thereby control production of aflatoxin from the fungi without killing the fungi.

Claims

1. A method for inhibiting aflatoxin which is produced by aflatoxin producing strains of Aspergillus parasiticus fungi, said method comprising:

treating the fungi with an effective amount of beta-ionone to inhibit and control the growth and sporulation of said fungi, without killing the fungi, thus eliminating the aflatoxin produced by said fungi.

2. The method of claim 1 wherein the effective amount of beta-ionone is about 1 μ

l to 100 μ

l.

3. The method of claim 2 wherein the Aspergillus parasiticus is NRRL 2999.
