  • Title: Mycotoxins in cereal grain. Part 12. Contamination with ochratoxin A and penicillic acid as indicator of improper storage of cereal grain.

    Journal: Nahrung; 1987; 31(1):81-4. PubMed ID: 3614319.
    Abstract:
    Formation of ochratoxin A and penicillic acid in wheat kernels at 6 moisture levels: 15, 18, 21, 24, 27 and 30% at 15 degrees C has been examined during 4 months of storage. The minimum time for formation of significant amount (0.5-1 mg/kg) of ochratoxin A and penicillic acid (6-8 mg/kg) in stored grain has been found for the various water contents as follows: 18%-16 weeks, 21%-6 weeks, 24% and more - 2 weeks. At 15% of moisture content formation of ochratoxin A and penicillic acid was not observed until 4 months of storage.
