AI Technical Summary

Technical Problem

The current tobacco extract preparation process lacks scientific research on the compounding of Zimbabwean re-dried fragments, mulberry leaves and green tea stems, resulting in a single aroma style and insufficient complexity, which makes it difficult to meet the needs of modern cigarette products.

Method used

Zimbabwean tobacco extract was prepared by using a mixture of re-dried Zimbabwean tobacco fragments, mulberry leaves and green tea stems, pre-treating the mixture with citric acid and malic acid solutions, enzymatically hydrolyzing it with a complex enzyme preparation of pectinase, cellulase and β-glucosidase, and then performing gradient extraction and nitrogen-protected vacuum concentration.

Benefits of technology

It enhances the richness and sweetness of tobacco extract aroma, reduces the generation of burnt and bitter off-flavors, and improves the retention rate and storage stability of volatile aroma components. It is suitable for flavoring and adding ingredients to cigarettes and for the preparation of tobacco sheets.

Abstract

本发明公开了津巴布韦烟草浸膏及其制备方法,属于烟草加工技术领域。本发明制备方法为:首先将津巴布韦复烤碎片与桑叶、绿茶梗混合,并采用含柠檬酸和苹果酸的酸性润料液进行润料预处理;随后加入由果胶酶、纤维素酶及β‑葡萄糖苷酶组成的复合酶体系进行酶促预转化处理;之后依次进行低温释香提取、中温释甜提取及高温短时增体提取,得到混合提取液;再经膜过滤除杂、氮气保护减压浓缩及熟化定型后,制得津巴布韦烟草浸膏。本发明通过植物辅料协同增香、酸性润料调控及复合酶促转化的联合作用,提高了烟草香气前体释放效率和挥发性香气成分保留率,所得烟草浸膏香气丰富、甜润柔和、杂气低、稳定性好。
