富平柿饼中霉菌的分离鉴定及防控技术研究

Studies on the Identification of Mould Causing Dried Persimmon Mildew and Mildew Proofing Measure

对霉变柿饼中的微生物进行了分离鉴定,将青霉属(Penicillium)、毛霉属(Mucor)和根霉属(Rhizopus)确定为引起霉变的主要污染菌。分别采用改变包装方式和添加防霉剂——霉克(Natamax)等防控措施对柿饼进行处理,结果表明密封充N2包装和在柿饼表面喷洒150 mg/L的霉克悬浮液可有效防治霉菌,可有效延长柿饼保质期,并且不影响柿饼原有风味与质量。实际生产中可将两种防控技术综合运用保藏效果更佳。

The microorganisms causing dried persimmon mildew were isolated and identified.The dominant mould was identified as Penicillium,Mucor and Rhizopus.In order to prevent the dried persimmon mildew,different packing methods were used and Natamax was added.The results showed that the nitrogen gas packing and 150 mg/L Natamax were effective measures to prevent dried persimmon mildew.In practical production,the combination of the two techniques could be used to achieve better preservation effect.
