Abstract
This study was intended to apply irradiation technology for the degradation of patulin from apples and apple juices by investigating their physical, mechanical, biological, and pharmacochemical properties in view of potential uses in the bio-industry. The patulin producing fungi was separated from in Korean apples. Totally, 16 morphological types of fungi were isolated from the apples and a patulin producing fungi was identified. The isolated patulin producing fungus was found to a represent species of Penicillium crustosum. The patulin, dissolved in distilled water at a concentration of 50 ppm was practically degraded by the gamma irradiation at the dose of 1.0 kGy, while 33% of the patulin was remained at apple juice. In conclusion, it was suggested that 1 kGy of gamma irradiation (recommended radiation doses for radicidation and/or quarantine in fruits) is effective for the reduction of patulin, but the nutritional elements should be considered because the radio-degradation effects are environment dependant. The effects of a gamma irradiation on the physiochemical and physical characteristics of apple was investigated during a post-irradiation storage at 4 and 25. Gamma irradiation dose not affect stability of the nutritional contents, functional properties and physical characteristics of apples, especially in the condition of a
