中文摘要: 蜂蜜中嗜渗酵母引起蜂蜜发酵产生二氧化碳从而导致蜂蜜腐败变质或导致蜂蜜从包装瓶或桶溢出甚至导致包装爆裂引发贮运安全问题。经过作者设计的专利超声波样机处理蜂蜜后,模拟快递运输振动,观察蜂蜜发酵产生泡沫情况,采用GB14963-2011《食品安全国家标准蜂蜜》测定了酵母计数并且观察超声波处理后结晶改变情况。结果表明,超声波处理5 min之后减少了90%的泡沫,处理6 min之后酵母计数只有原来的14%即152 CFU/g,达到了GB14963-2011酵母计数小于200 CFU/g的要求,在设计处理时间之内没有观察到结晶性质的改变。
Abstract:Abstract:Osmophilic yeast causes honey fermentation to produce carbon dioxide that causes the safety of transportation of the honey to overflow or even burst from the bottle or bucket of package,and lead to the honey spoilage completely.The research perfectly resolved the problem using ultrasonic process.The sample honey processed by patent ultrasonic sample machine designed by the authors and simulated the vibration of express transportation,the production of fermented foam was observed.Using the laboratory method in the Chinese honey standard of GB14963-2011《Food safety national standard,honey》,the yeast count and crystallization were investigated before and after ultrasonic processes.The results revealed that the 90%foam was decreased after 5 min ultrasonic process,and that yeast count was only 14%,i.e.152 CFU/g,compared with that before ultrasonic process and meets the request of 200 CFU/g of yeast count in the Chinese honey standard of GB14963-2011,and in the whole processing time spans no changes of honey crystallization was observed.
