Determination of Geotrichum mold in cream style corn: collaborative study

The official method for the determination of Geotrichum mold in canned fruits and vegetables, 44.079, is not satisfactory for use with cream style corn. The kernels are too small to be retained by the first 2 sieves, and the presence of starch interferes. The proposed method uses a smaller series of sieves (Nos. 16, 70, and 230), which enables more of the product to be separated from the mold before the No. 230 sieve, and specifies hot (45-55 degrees C) wash water for the sieving steps to remove the starch. The method has been adopted official first action.
