Alfalfa leaf extract preparation method and use as tobacco product additive

Abstract

The invention discloses an alfalfa leaf extract preparation method and a use as a tobacco product additive. The method comprises the steps of using alfalfa leaves as extraction raw materials, and uniformly mixing alfalfa leaves with extracting agent according to volume ratio of 1:(10-30) to obtain mixture; extracting the mixture for 1-5h at 50-90DEG C and performing separation to obtain primary material liquid; adding water into the material liquid, separating sediment, performing separation to obtain secondary material liquid and concentrating the secondary material liquid to extract; redissolving the extract by using 5-10 multiples of extracting solution, filtering and separating byproducts and tertiary material liquid, and concentrating the tertiary material liquid to extract to obtain alfalfa leaf extract. By adding the alfalfa leaf extract prepared by adopting the method disclosed by the invention into tobacco products, an effect of effectively increasing the flavor of the tobacco products is achieved, the flavor is rich and the solidity of smoke is increased; the extract can also endow the tobacco products with unique flavor tones and notes, and can be used as a characteristic flavor.

Description

technical field [0001] The invention relates to the application of a natural plant extract in tobacco products, in particular to a preparation method of alfalfa leaf extract and its use as an additive of tobacco products. Background technique [0002] The core competitiveness of "Chinese-style cigarettes" is to form a characteristic style of products, reflect individualization and differentiation, and adapt to the smoking habits and consumption needs of Chinese consumers. Flavors and fragrances for Chinese-style cigarettes are the "soul" of Chinese-style cigarette products and the mystery of the formation of the style and characteristics of "Chinese-style cigarettes". Scientifically adding flavors and ingredients to cigarettes is an important means to highlight the individual style of cigarette products. At the same time, in order to improve the safety of smoking, harm reduction and coke reduction have become an important part of "Chinese cigarettes". While reducing cigare...

Problems solved by technology

However, at present, alfalfa research is mostly used in agriculture, animal husbandry and medicine, and there is no literature report that alfalfa extract is used as a cigarette additive.

And in the process of our research, we found that the alfalfa extract obtained by simple solvent extraction has a relatively large negative effect and cannot meet the requirements for use as a cigarette additive
