Twenty-six market samples and four laboratory-prepared samples of "ogiri" were screened for aflatoxin contamination. Aflatoxins were not detected in any of the samples. The fermented product (ogiri) was prepared with Aspergillus flavus-contaminated melon seeds. Losses of 64.7% aflatoxin B1 and 82.9%

✦ Synopsis
Abstract
The traditional method for preparing Ogiri is described. Microorganisms associated with the various stages of fermentation were mainly bacteria; the genera frequently isolated are Pediococcus, Proteus, Klebsiella, Escherichia and Bacillus. The morphological and biochemical properties of the isolates are studied in pure cultures. While the temperature remained fairly constant during the fermentation, the pH increased sharply. The predominant amino acids are alanine, lysine and glutamic acid. Arginine and proline are present in low quantities. Threonine is completely absent.
