Abstract

The invention provides a preparation method and application of a composite tobacco leaf extract. Aired tobacco stems, corn cobs and a rice bran composite biological material are adopted as immobilization carriers for adsorbing microbial aroma-producing strains, compounded and aired tobacco leaf raw materials are subjected to incubated hydrolysis fermentation, and then in combination with a continuous countercurrent ultrasonic extraction technology, the composite tobacco leaf extract is prepared. The composite tobacco leaf extract has rich natural tobacco fragrance and has a fresh fruit aroma,a wine aroma, a milk aroma, a barbecue meat aroma, a baked bread aroma, a roasted cheese aroma and other rich natural complex aromas, the irritating property is reduced, the quality of the spices is improved, the purification and separation steps are simple, the process conditions are mild, the extraction rate is increased, and the production efficiency is improved; the composite tobacco leaf extract is applied to traditional cigarettes and novel heat-not-burn cigarettes and is harmony with cigarette fragrance and uniform in style, the concentration of the smoke is increased, the satisfactionfeeling is improved, the cigarette fragrance is enhanced, the irritating property 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...
