Preparation method of C5 fatty acid monosaccharide ester and application in cigarette and cigarette

Abstract

The invention discloses a preparation method of C5 fatty acid monosaccharide ester, an application of the C5 fatty acid monosaccharide ester in cigarettes and a cigarette. The preparation method comprises the following steps: (1) preparing a mixed ionic liquid, wherein the volume ratio of a hydrophilic ionic liquid to a hydrophobic ionic liquid in the mixed ionic liquid is 1:0.1-1:10; (2) adding a monosaccharide water solution with the volume 0.1-10 times that of the mixed ionic liquid into the mixed ionic liquid, uniformly mixing, carrying out reduced pressure concentration and water removal at the temperature of 50-60 DEG C, and removing the undissolved monosaccharide to obtain a supersaturated monosaccharide ionic liquid; (3) adding C5 fatty acid into the supersaturated monosaccharide ionic liquid, wherein the mass concentration of the C5 fatty acid in the supersaturated monosaccharide ionic liquid is 10-1000g / L, adding lipase to form a reaction system according to the consumption proportion of the lipase to the C5 fatty acid of 5-500U / g, adding a drying agent into the reaction system to remove water, and enabling the C5 fatty acid to react with the monosaccharide in the presence of the lipase at the reaction temperature of 40-55 DEG C to generate C5 fatty acid monosaccharide ester; and (4) extracting and purifying the C5 fatty acid monosaccharide ester.

Description

technical field [0001] The invention relates to the preparation of fatty acid monosaccharide ester, in particular to a preparation method of C5 fatty acid monosaccharide ester and its application in cigarettes and cigarettes. Background technique [0002] Fatty acids, especially C5 carbon chain length fatty acids, are an important class of aroma substances in tobacco, which can add alcohol, fruit and cheese-like sweetness to tobacco products, and enhance smoke. However, these medium and low-carbon chain fatty acids are volatile and will gradually volatilize during cigarette processing and storage. Because cigarettes not only have extremely high temperatures in the combustion area, but also have a relatively high temperature in the pyrolysis distillation area. , Therefore, these acids will volatilize sharply during burning and smoking, thereby affecting the quality of cigarette smoke and the inconsistency of smoking taste. Therefore, how to improve the stability of low-carbo...
