Tobacco extract, preparation method thereof and novel tobacco product

Abstract

The invention provides a tobacco extract, a preparation method thereof and a novel tobacco product. The preparation method of the tobacco extract comprises the following steps of: mixing a crushed tobacco raw material with water, and adding preparations such as cellulase, alpha-amylase and pectinase for primary enzymolysis; adding neutral protease for secondary enzymolysis; mixing the treated tobacco mixture with a high-concentration ethanol solution, and leaching the newly obtained mixture, carrying out solid-liquid separation after leaching the mixture to obtain a leaching solution, and filtering the leaching solution to obtain a tobacco clear solution; concentrating the tobacco clear liquid under reduced pressure until the solid content is 40-45%; adding amino acid, and performing concentrating under reduced pressure until the solid content is 59-61%, so as to obtain a product, namely the target tobacco extract. The method is simple in procedure, macromolecules such as cellulose, starch, pectin and protein in the tobacco extract are removed, and the aroma richness of the tobacco extract is improved through the Maillard reaction. The novel tobacco product containing the tobaccoextract meets the requirement of the novel tobacco product for highlighting the characteristic aroma of tobaccos.

Description

technical field [0001] The invention relates to tobacco technology, in particular to a tobacco extract, its preparation method and novel tobacco products. Background technique [0002] At present, the domestic new-type tobacco product market is booming, and the mainstream products are heat-not-burn cigarettes with reconstituted tobacco leaf sheets as pods, and atomized electronic cigarettes with volatile e-liquid as pods. Within a certain temperature range, the heated pod produces aerosols, satisfying the experience similar to smoking traditional cigarettes. Due to the controllable chemical composition of new tobacco products, it has attracted more and more attention. [0003] The style of new tobacco products depends on the tobacco extract. There are three extraction methods of tobacco extract commonly used in my country's tobacco industry today: the first is to use 50-80% ethanol solution (v / v) to extract tobacco raw materials, and obtain products after concentration; th...
