Abstract

Fruit jams as well as other nourishing products of vegetal origin may present as contaminants extraneous materials and mold mycelial, when inadequate raw material is used or good manufacture
practices are not adopted. The objective of the present study was to standardize analytical procedures for quantification of mold mycelials and Geotrichum mold, and extraneous materials in fruits jams and to evaluate such contaminants in 117 samples of the products obtained from supermarkets in the city of São Paulo, Brazil. The methods of the Association of Official Analytical Chemists International (AOAC) were adopted. As result of the standardization, a 1+6 dilution was established for the pineapple, plum, fig and grape jams for the Howard mold counting. According to the results, 56.4% of the samples presented extraneous materials (mainly insects fragments); 73.0% contained mycelial fragments for the Howard mold counting and 23.0% were positive for mycelial fragments of Geotrichum mold. The plum and pineapple jams presented the lowest number of samples with the studied contaminants. Considering the current food legislation, the evaluated products presented high index of contamination for mycelial fragments and extraneous materials.
