Patulin production in apples decayed by Penicillium expansum.
Sixty isolates of Penicillium expansum were tested for patulin production in decaying apples. All the isolates were found to produce the mycotoxin patulin as determined by thin-layer chromatography. Since patulin is known to be stable in many apple products, the results indicate that apple products made partially from apples decayed by P. expansum will contain patulin which may present a health...
متن کاملProduction of patulin by Penicillium expansum.
Twenty-seven isolates of Penicillium expansum Lk. ex Thom obtained from Europe, Australia, and North America from seven different fruit hosts all produced patulin in culture. Six isolates were essentially nonpathogenic in apple fruits. In culture, patulin generally accumulated to much higher levels than in apple fruits. At all temperatures permitting fungus growth, patulin was produced. However...
متن کاملPatulin Accumulation In Apples During Storage by Penicillium Expansum and Penicillium Griseofulvum Strains
A part of apples destined to juice production is generally of poor quality. Apples from cold storage or recently harvest (ground harvested or low quality apples) are stored under ambient conditions until they are processed. Since Penicillium expansum and P. griseofulvum are the principal fungal species isolated from stored apples in Brazil, the objective of this study was to investigate the abi...
متن کاملPhytic Acid Enhances Biocontrol Activity of Rhodotorula mucilaginosa against Penicillium expansum Contamination and Patulin Production in Apples
The effect of Rhodotorula mucilaginosa in combination with phytic acid (PA) on blue mold decay and patulin contamination of apples was investigated. Results from this study show that different concentrations of PA were effective in reducing the disease incidence of apples and that PA at concentration of 4 μmol/mL, decreased the incidence of blue mold decay in apples from 86.1 to 62.5%, and show...
متن کاملThe effect of culture preservation techniques on patulin and citrinin production by Penicillium expansum Link.
AIMS To study the influence of culture preservation methods and culture conditions on the production of the mycotoxins patulin and citrinin by Penicillium expansum. METHODS AND RESULTS Ten strains of Penicillium expansum were preserved using subculture and maintenance at 4 degrees C, mineral oil, drying on silica gel and freeze-drying. Patulin and citrinin production was assessed on yeast ext...
