The invention belongs to the technical field of cigarette paper and flavors and fragrances, and particularly relates to a preparation method of cigarette paper containing hydroxy-acid alcohol ester.
Background
The cigarette paper is an essential auxiliary material in the cigarette manufacturing process, and burns together with tobacco shreds in the cigarette smoking process, so that the cigarette paper has a burnt paper taste and the smoking quality of the cigarette is influenced. The cigarette paper is added with fragrance, so that the positive influence of the combustion process of the cigarette paper on the cigarette smoking can be improved.
The prior cigarette paper flavoring method mainly comprises the following technical means: 1) adding the spice directly to the cigarette paper in the form of coating liquid; 2) performing cyclodextrin molecule encapsulation or embedding on the spice to prepare a paste, and then adding the paste into the cigarette paper in a coating liquid manner; 3) performing cyclodextrin molecule encapsulation or embedding on the spice, performing powder spraying and drying to obtain powder, and adding the powder into the cigarette paper in a filling manner; 4) the perfume is loaded on the inorganic porous material, the surface of the porous material is coated with the water-insoluble high polymer material to form a film for sealing the perfume, and the film is added to the cigarette paper in a filling mode.
Alcohol spices are important fragrant raw materials in cigarettes, but the application of the alcohol spices to the perfuming of the cigarettes often has two problems: the volatility causes the fragrance to be difficult to store for a long time, and in addition, the smoked taste is inconsistent.
For example, leaf alcohol naturally exists in various plants, is a representative spice of green aroma, has fresh green leaf aroma, has special herb aroma and leaf odor after being diluted, and is widely usedIs applied to blending of essence with natural fresh flavor[1]. To increase the processing and storage resistance of folyl alcohol, the following studies have been mainly made: minjie (Chinese character)[2]And the leaf alcohol microcapsule is prepared by taking chitosan oligosaccharide as a wall material, and the particle size and the embedding rate of the leaf alcohol microcapsule are examined. Zhao Ming Qin etc[3]The leaf alcohol is derived into 3-picolinic acid leaf alcohol ester, the thermal cracking behavior of the 3-picolinic acid leaf alcohol ester at different temperatures is discussed, a small amount of free leaf alcohol can be generated in a cracking state, and the cigarette flavoring effect of the 3-picolinic acid leaf alcohol ester is investigated. Poplar and stannum root for flood and deluxe[4]The leaf alcohol is derived to prepare leaf alcohol glycoside (namely cis-3-hexenyl- β -D-glucopyranoside), the thermal degradation behavior and the products of the leaf alcohol glycoside are examined by de-Wangcui and the like, the optimal temperature for the leaf alcohol glycoside to release the leaf alcohol is 350 ℃, the characteristic product of thermal cracking is the leaf alcohol, and the main cracking reaction is the breakage of oxygen glycosidic bond[5]。
In the prior art, a technical route for applying the-hydroxy acid alcohol ester latent aromatic to perfuming cigarette paper is not available.
