摘要
为研究臭氧对过度醇化片烟原料质量的影响并解决过度醇化片烟霉变问题,分别设置了2组不同臭氧浓度水平(0、50、100、150 μmol/mol;0、100、200、300 μmol/mol)和3个臭氧处理时间(30、60、90 d),研究臭氧对已醇化3年和7年烟叶的祛霉效果及颜色和品质的影响.结果表明,200 μmol/mol臭氧处理烟叶60d后即可杀灭霉菌并祛除大部分霉味,50～150 μmol/mol臭氧处理烟叶90d后可明显抑制颜色向棕黑色方向转变.对于已醇化3年烟叶,臭氧处理会产生较大的负面作用,使品质变差,对于已醇化7年烟叶,臭氧处理会产生较大的正面作用,且100 μmol/mol臭氧对烟叶品质的改善效果最优.因此,臭氧可以改善过度醇化片烟原料质量,提高其利用价值,并有效祛除烟叶霉变,解决片烟原料霉变问题.但是,对于刚过最佳醇化期的烟叶,不宜采用臭氧处理.
Abstract
In order to study the effect of ozone on the quality of over aged tobacco raw materials and solve the problem of over aged to-bacco mold,two sets of different ozone concentration levels(0、50、100、150 μmol/mol;0、100、200、300 μmol/mol)and three ozone treatment times(30、60、90 days)were set up to study the effects of ozone on the anti mold effect,color and quality of aged tobacco leaves for 3 and 7 years.The results showed that treating tobacco leaves with 200 μmol/mol ozone for 60 days could kill mold and re-move most of the moldy odor.After 90 days of treating tobacco leaves with 50～150 μmol/mol ozone,the color transition to brownish black was significantly inhibited.For tobacco leaves that had been aged for 3 years,ozone treatment would have a significant negative effect,resulting in poor quality.For tobacco leaves that had been aged for 7 years,ozone treatment would have a significant positive ef-fect,and 100 μmol/mol ozone had the best effect on improving the quality of tobacco leaves.Therefore,ozone could improve the quali-ty of excessively aged tobacco raw materials,increase their utilization value,and effectively eliminate tobacco leaf mold,solving the problem of tobacco raw material mold.However,for tobacco leaves that had just passed the optimal aging period,ozone treatment should not be used.
