Embodiment 1

[0032] A preparation method of tobacco blueberry extract, comprising the following steps:

[0033] (1) Prepare fresh blueberries and blueberry leaves, and send the blueberry leaves into supercritical CO2 Extraction equipment, resulting in supercritical CO containing blueberry leaf extract 2 The fluid is directly sent into a high-pressure sealed container loaded with blueberries, cooled to 28°C, and depressurized to 6.89MPa to make supercritical CO 2 liquefaction. The container is provided with a stirrer, and the stirrer is turned on to break the blueberries and make the paste blueberries evenly distributed in the liquid CO 2 Medium; further reduce the pressure to atmospheric pressure, part of the liquid CO 2 Evaporate, leaving liquid CO 2 Forming dry ice containing mushy blueberries; crushing the dry ice and sending it to an expansion tower, heating it with a 320°C hot air stream, and sublimating the dry ice to obtain a mixture.

[0034] (2) Inoculate the lactic acid bacte...

Abstract

The invention relates to the technical field of tobacco flavors, in particular to a preparation method of a tobacco blueberry extract. It consists of the following steps: sending blueberry leaves into supercritical CO 2 Extraction equipment, obtained supercritical CO containing blueberry leaf extract 2 The fluid is directly fed into a high-pressure sealed container loaded with blueberries, and the temperature and pressure are reduced to make supercritical CO 2 Liquefy, then stir to break up the blueberries and distribute the mushy blueberries evenly in the liquid CO 2 medium; further reduce the pressure, the remaining liquid CO 2 forming dry ice containing mushy blueberries; pulverizing the dry ice and heating with hot air, and sublimating the dry ice to obtain a mixture; mixing and fermenting the mixture with immobilized lactic acid bacteria; filtering the fermentation product to obtain a blueberry extract. The present invention prepares blueberry extract with rich fruit aroma and complete nutrition through antioxidant protection and immobilized lactic acid bacteria fermentation, which is used for cigarettes and has rich tobacco aroma, increased fruit sweetness, soft smoke, reduced throat irritation, and improved taste , reduce the residual effect.

Description

technical field [0001] The invention relates to the technical field of flavors for tobacco, in particular to a preparation method of blueberry extract for tobacco. Background technique [0002] In tobacco products, the aroma and taste of tobacco are very important. Adding spices is a key link in the cigarette process, and it is also one of the effective means to improve the product style and improve the quality of cigarette aroma. It can provide consumers with some aroma and Cigarette products with satisfying taste. At present, most tobacco flavors and fragrances added to tobacco in my country are prepared through extraction and chemical synthesis of natural animals and plants. Due to limited natural plant resources and harsh chemical synthesis conditions, such methods are limited. At the same time, although the prepared tobacco flavoring is simple in market operation, it has the disadvantages of monotonous aroma, insufficient improvement of tobacco, and inconspicuous effec...
