Effect of temperature and water activity on growth and ochratoxin A production boundaries of two Aspergillus carbonarius isolates on a simulated grape juice medium.
AIMS To develop and validate a logistic regression model to predict the growth and ochratoxin A (OTA) production boundaries of two Aspergillus carbonarius isolates on a synthetic grape juice medium as a function of temperature and water activity (a(w)). METHODS AND RESULTS A full factorial design was followed between the factors considered. The a(w) levels assayed were 0.850, 0.880, 0.900, 0....
متن کاملOccurrence of Ochratoxin A in Grape Juice of Iran
Ochratoxin A (OTA) is one of the most important mycotoxins that contaminate a broad range of agricultural and food products. In this study, the occurrence of OTA in available brands of grape juice in Iran purchased from retail outlets or producer were determined for the first time using high-performance liquid chromatography (HPLC) with immunoaffinity columns(IAC) as the clean-up step. The aver...

متن کاملManaging ochratoxin A risk in the grape-wine food chain.
The main source of ochratoxin A (OTA) in the wine food chain is the infection of grapes by "black aspergilli" in the field. OTA-producing black aspergilli include principally Aspergillus carbonarius, followed by A. niger and possibly A. tubingensis. They are opportunistic fungi that develop particularly on damaged berries at ripening, although they may occur and form OTA on grapes from veraison...
متن کاملConditions for production of ochratoxin A by Aspergillus species in a synthetic medium.
Trace elements were required by Aspergillus melleus and A. ochraceus, but not by A. sulphureus, to grow and to elaborate ochratoxin A. The composition of the medium affected the synthesis of the toxin more than the growth of the mycelium.
