The efficacy of clove oil, UV-C light and their combination for the inhibition of mold growth on the surface of dried persimmon fruits during the storage period of 28 days at 20 °C were investigated in this study. The inactivation kinetics of UV-C resistant mold cultures inoculated to dried persimmon surfaces were determined at UV-C doses in the range of 0.6–12.0 kJ/m². Disc diffusion and microdilution methods were used to evaluate the antifungal activity of the clove oil against Rhizopus oryzae, Alternaria tenuissima and Aspergillus niger previously isolated from dried persimmon fruits. Minimum inhibitory concentrations of clove essential oil against R. oryzae, A. tenuissima and A. niger were 1.56% (v/v) and the minimum fungicidal concentrations were 6.25% (v/v), 3.12% (v/v) and 6.25% (v/v), respectively. UV-C treatments showed limited reductions in the number of molds inoculated to dried persimmon discs regardless of the UV-C dose. Combined treatments of UV-C and clove oil resulted in maximum reductions of 0.64 and 0.68 log cfu/cm² for R. oryzae and A. niger, respectively. Sensory evaluation results showed that all the treatments could maintain the appearance and texture of samples, moreover the highest sensory evaluation score was obtained for the clove oil (1.56% v/v) treatments in terms of flavour and overall acceptability. Application of clove oil (1.56% v/v) to dried persimmon fruits was extended the product shelf life at least 28 days. By using combination of UV-C light and clove oil treatments, the inhibition of mold growth on the surface of dried persimmons has been achieved.

本研究研究了丁香油，UV-C灯及其组合在20°C储存28天期间抑制柿饼干表面霉菌生长的功效。在0.6-12.0 kJ / m ^2的UV-C剂量下测定了接种到干燥柿子表面的抗UV-C霉菌培养物的失活动力学。圆盘扩散和微量稀释方法用于评估丁香油对先前从干燥的柿子果实中分离的米根霉，链格孢和黑曲霉的抗真菌活性。丁香精油对米曲霉，球果曲霉和黑曲霉为1.56％（v / v），最小杀真菌浓度为6.25％（v / v），3.12％（v / v）和6.25％（v / v）。UV-C处理显示，与UV-C剂量无关，接种到干燥柿饼盘上的霉菌数量有限地减少。UV-C和丁香油的组合处理导致的0.64和0.68日志最大降低CFU /厘米²为米根霉和黑曲霉， 分别。感官评价结果表明，所有处理均能保持样品的外观和质地，此外，丁香油（1.56％v / v）处理在风味和总体可接受性方面均获得最高感官评价得分。将丁香油（1.56％v / v）施加到柿饼上可以延长产品的保质期至少28天。通过结合使用UV-C光和丁香油处理，可以抑制干燥柿子表面霉菌的生长。
