Preparation method of jujube subcritical extract and application of jujube subcritical extract in cigarette

Abstract

The invention relates to a preparation method of a jujube subcritical extract and an application of the jujube subcritical extract in a cigarette. The method comprises the following steps: a, drying the preprocessed jujube at the temperature of 50 to 80 DEG C, and then pulverizing the dried jujube until the granularity is 10-100 meshes; b, subcritically extracting the jujube powder obtained in the step a for 0.1-2 hours by utilizing the subcritical extracting agent under the condition that the temperature is 0-50 DEG C and the extracting pressure is 0.5-3Mpa, and separating the extract liquid by use of the decompression evaporation principle to obtain the jujube subcritical extract, wherein an ethanol solution is used as a carrier agent, the concentration is 50 to 95 percent, and the consumption of the ethanol solution is 1 to 5 times that of the jujube powder. The jujube subcritical extract is used as cigarette liquid so as to be added into a cigarette tobacco shred, the exclusive chemical component can be generated when the cigarette is burned, so that the quality of the cigarette can be obviously improved. Under the situation that the original performance of the cigarette is not changed, the smoking quality of the cigarette is improved, and the real production significance and value are better.

Description

technical field [0001] The invention relates to plant extraction and its application, in particular to the preparation method of the jujube extract and its application in cigarettes. The application of this technology does not change the existing processing technology of the cigarette, and can improve the sensory quality of the cigarette. [0002] Background technique [0003] As the problems of smoking and health attract more and more attention, it is an inevitable development trend of cigarettes to improve the smoking safety of cigarettes, increase health care functions, and reduce harmful components in cigarette smoke. Therefore as soon as cigarette varieties such as ginseng cigarettes and peppermint cigarettes appear on the market, materials with unique functions or tastes such as ginseng and peppermint are added in shredded tobacco. [0004] Jujube is a plant of the genus Jujube in the family Rhamnaceae. It is a food with both medicine and food. According to the theor...

Problems solved by technology

The extremely high pressure limits the expansion of the effective volume of the equipment, and it is difficult to achieve industrial production. At the same time, the high equipment manufacturing and operating costs restrict the application of this technology in the production of natural product active ingredients

Simultaneous distillation and extraction ("Analysis of Aroma Components of Natural Jujube Spices and Its Application in Cigarettes", Tobacco Science and Technology, 2003 (3)) only extracts some aroma components, and the extraction time is long (3h, concentrated overnight), The temperature is high (60°C), and the subsequent treatment introduces foreign substances (anhydrous sodium sulfate), which affects the product and the yield is very low

Due to the thermal sensitivity of high value-added physiologically active substances in natural products, conventional heat reflux extraction methods and organic solvent extraction methods not only have low yields, but also destroy functional components.
