Abstract

The present invention provides a preparation method and application of composite tobacco leaf extract, which uses air-dried tobacco stems, corncobs, and rice bran composite biological materials as immobilized carriers, absorbs microbial aroma-producing strains, incubates, hydrolyzes and ferments composite air-dried tobacco leaf raw materials, and then Combined with the continuous countercurrent ultrasonic extraction technology, the compound tobacco leaf extract is prepared, which has a strong natural tobacco aroma, with rich natural compound aromas such as fresh fruit, wine, milk, barbecue, toasted bread and grilled cheese, etc., irritating reduced, the quality of spices is improved, the purification and separation steps are simple, the process conditions are mild, the extraction rate and production efficiency are improved; it is used in traditional cigarettes and new heat-not-burn cigarettes, and it is coordinated with cigarette aroma and style, increasing smoke concentration and improving satisfaction The taste is rich, the aroma is rich, the irritation is reduced, and the taste is improved.

Description

technical field [0001] The invention relates to the field of tobacco additives, in particular to a preparation method and application of a composite tobacco leaf extract. Background technique [0002] Tobacco additives are additives to improve the physical and chemical properties of tobacco, including flavor essences, humectants, combustion enhancers, anti-mold agents and adsorbents. The production of low-tar cigarettes needs more flavorings to make up for the lack of flavor. The purpose of tobacco product flavoring is to cover up the irritation and miscellaneous gas of natural tobacco, and to enhance or improve its fragrance. Due to its naturalness, safety and natural compound aroma, natural flavors are more catering to consumers' health needs, but they still have low extraction efficiency, many solvent residues, high impurity content, low purity, and high cost due to complicated purification steps. , Some of them have obvious characteristic aroma, which will cause the ad...
