Description
Technical Field
The invention belongs to the field of tobacco industry application, and particularly relates to a method for improving limonene release balance in bergamot oil essence.
Background
Limonene, also known as limonene, dipentene and the like, is a natural monoterpene widely existing in Rutaceae plants, such as bergamot, is rich in limonene, has pleasant lemon flavor fragrance, and has great potential and economic value as a natural substance because of the functions of bacteriostasis, corrosion resistance, oxidation resistance, flavoring and the like. The essence rich in limonene is added into the cigarette, so that the product has limonene, and the cigarette product also has the functional characteristic of limonene. At present, most domestic cigarette enterprises hope to increase the content of limonene in cigarette products by adding essence rich in high content of limonene in cigarette production. However, from the practical situation, simply improving the content of the limonene in the cigarette cannot well improve the quality of the final product, because the limonene is not only required to be added in the cigarette, but also the transfer balance of the limonene in the combustion process of the cigarette needs to be considered, if the balance is poor, the suction feeling of the final product also has larger fluctuation, so that the consumption experience is affected, and the transfer balance means the consistency of the limonene in the mouth-by-mouth smoke in the combustion process of the cigarette, the better the balance is, the uniform release of the limonene in different suction stages before, during and after the suction feeling is not generated, and the sensory evaluation is high.
Therefore, if the functional characteristics of the limonene are expected to be well applied to the cigarette products, the problem that the limonene content in the cigarettes is not simply improved is solved, but the important attention is paid to how to uniformly release the limonene in the cigarette combustion process after the limonene content in the cigarettes is improved, and the reason that the limonene transfer balance in the cigarette products is poor is that the tobacco shreds need to be combusted, the limonene is sucked along with the main stream smoke gradually, and the added limonene-rich essence cannot be gradually released at the moment, so that the requirement of the tobacco shred combustion process on the essence release balance cannot be met, the problem that the limonene transfer balance is poor is caused, the functional characteristics of the limonene cannot be well exerted, the quality fluctuation of the cigarette products is large, and the cigarette products cannot be well improved.
In addition, the cigarette processing process has a high-temperature treatment process, and if bergamot oil essence is directly added in the prior art, the bergamot oil essence has higher limonene loss rate after the high-temperature cut tobacco baking process.
Therefore, it is important to develop a method for releasing limonene in bergamot oil essence in a balanced manner in the field of cigarette industry and a method for reducing the limonene loss rate of bergamot oil essence after a high-temperature cut tobacco baking process.

In addition, the selection of the emulsifier, the ratio of the mass of the emulsifier to the mass of the auxiliary emulsifier is critical to the limonene loss rate of the bergamot oil essence after the high-temperature tobacco shred baking process, and the invention can meet the requirements of high-temperature treatment in cigarette processing.
As can be seen from tables 3 and 4, according to the transfer condition of the limonene in the total particulate matters of the smoke from 1 to 7 mouths, in order to further analyze the release balance of the limonene in the smoke of cigarettes, the 2 nd to 4 th mouths are taken as the first half section and the 5 th to 7 th mouths are taken as the second half section, single-factor analysis of variance is carried out on the transfer rate data of the limonene in the smoke of the first half section and the second half section, the variance of the embodiment 1 is 5.14 and is smaller than a critical value, which indicates that the transfer rates of the first half section and the second half section of the limonene of the embodiment 1 have no significant difference, the release of the limonene is more balanced than that of the comparative example in the burning process of cut tobacco, and although the variances of other embodiments are smaller than the critical value, the loss rate of other embodiments is higher in the high-temperature treatment process. Considering the emulsifier used in example 1 of the present invention, the ratio of the mass of the emulsifier to the mass of the co-emulsifier is more suitable.
As can be seen from table 5, the scores of the cigarette samples prepared in example 1 in the aroma characteristics, the smoke characteristics and the taste characteristics are better than those of the other examples and the comparative examples, which further illustrates that the cigarette samples prepared in example 1 are combusted to release limonene uniformly, and the limonene is sucked along with the main stream smoke gradually, so that the functional characteristics of the limonene are well exerted, the quality of the cigarette products is stable, and the overall sensory quality of the cigarette samples is improved better.
