| Summary: | also known to produce this mycotoxin. Patulin is most and stable, thus facilitating its use in the prescreening of anthroylnitrile. The derivative is added to the minicolumn apple products. apples, grapes, and corn. It is produced primarily by assay was found to be accurate and rapid. Also, the patulin Briefly, the sample is extracted with ethyl acetate and commonly found in apple products where its presence may concentrating column). Patulin is then partitioned by constitute a human health risk. At present, the best method contaminated apple juice and products. A field-practical detection for this assay was determined to be 50 ppb. This detector and viewed under longwave (UV) light. The limit of detector were shown to be chemically stable, requiring no for control of patulin is the detection and diversion of glass n-minicolumn at the interface of a layer of packed level of 50 ppb or greater, can be easily detected as the method for the chemiselective immobilization and detection of neutral sand and narrow band silica gel. Patulin, at the passed through a silica gel cartridge (or silica gel patulin has been developed in our lab. In this new method, Patulin is a mycotoxin found in many commodities including Penicillium expansum and P. patulum although many other polarity and eluted from the cartridge with acetonitrile. presence of a bright yellow fluorescent band with this assay. special treatment for storage up to 20 weeks. In summary, species of Penicillium, Aspergillus, and Byssochlamys are the assay was shown to be rapid, practical, easy to perform, the derivative of patulin is selectively adsorbed in a small The eluant (containing patulin) is derived with 9- |
