dc.description.abstractSamples of guava, strawberry and grape jams were analyzed to determine the presence of filth and mold filaments, and to test their authenticity. Eighty percent of the samples (36/45) presented at least one extraneous material. According to the type of fruit, in 100.0% (15/15), 73.3% (11/15) and 66.7% (10115) of the samples of guava, strawberry and grape jams, respectively, at least one extraneous material was found. the extraneous materials found were mold filaments, insect fragments, mites, non-edible plant parts (leaves and stems), maggots, a whole insect, a nylon thread, a piece of plastic material, and a metallic particle. No foreign plant tissue was found in any sample when compared to authentic fruit tissues. (C) 2003 Elsevier B.V. All rights reserved.en
