Abstract

Different moulds were isolated from traditional Korean bakery products. The moulds were present on the surface. The main strains were Eurotium amstelodami, E. herbariorum, Penicillium aurantiogriseum, Aspergillus flavus and Penicillium commune. Penicillium olsonii, P. viridicatum, P. cyclopium, P. chrysogenum, P. expansum, Eurotium chevalieri, E. repens, Aspergillus niger, A. ochraceus, Cladosporium cladosporioides, Rhizopus nigricans and Mucor racemosus were also isolated. The spoilage seemed to depend on the Aw (0.85±0.5) values of the products. Eurotium spp. had in vitro the Aw limit of 0.80, in contrast the other strains had 0.85 or 0.90, depending on the growth temperature and the strains. The toxic potential of the isolated strains was also investigated: Eurotium spp. did not produce any mycotoxins, in contrast OTA (Ochratoxin A) was produced by A. ochraceus and A. niger, Aflatoxins were produced by A. flavus and cyclopiazonic acid was produced by P. commune and patulin by P. expansum. To prevent moulds growth it was suggested to add preservatives and to package in Modified Atmosphere.
