Problems solved by technology

[0003] Most of the cigarette filters are single cellulose acetate filter rods, which cannot absorb ammonia in cigarette smoke well. At present, some functional materials are added to the filter rods to improve the adsorption effect. For example, Chinese patent document (CN102987564A) Disclosed is a method for adding β-cyclodextrin-g-lactic acid copolymer active material particles into a fiber substrate to reduce the ammonia content of 10.2-35.1% in smoke
Although this technology can selectively reduce ammonia in mainstream smoke, the preparation process of this functional material is complicated, the cost of the filter rod is high, the reproducibility and stability of the experiment are poor, and the possibility of industrialization is small

Abstract

The invention belongs to the field of a tobacco product, and particularly relates to a method for preparing extract of momordica charantia. The method comprises the following steps of: (1) leaching a momordica charantia sample by ethanol solution, and separating to obtain original leaching solution; (2) carrying out extraction on the original leaching solution by n-butyl alcohol, and separating to obtain extraction liquid. The invention further relates to extract of momordica charantia, a composition for tobacco and application of the extract of momordica charantia. When one or more of momordica saponins A, momordica saponins B, the extract of momordica charantia disclosed by the invention and the composition for tobacco, which is disclosed by the invention, are added into a cigarette holder, a filter tip or a filter stick to produce a cigarette, ammonia content in mainstream smoke of the cigarette can be obviously reduced.

Description

technical field [0001] The invention belongs to the field of tobacco products, and in particular relates to a method for preparing bitter melon extract, and also relates to the prepared bitter melon extract and its application. Background technique [0002] Ammonia is one of the 44 harmful components of cigarette smoke in the "Hoffman List", which can stimulate and damage the human respiratory tract. The ammonia content in fresh tobacco leaves is very small. During the fermentation process of tobacco leaves, the metabolic oxidation and deoxygenation of proteins and amino acids occur, which increases the ammonia content in tobacco leaves. Therefore, it is necessary to selectively reduce the ammonia content in flue gas by some technical methods. [0003] Most of the cigarette filters are single cellulose acetate filter rods, which cannot absorb ammonia in cigarette smoke well. At present, some functional materials are added to the filter rods to improve the adsorption effect....
