Heartleaf houttuynia herb and radix isatidis compound extract and application thereof as additive of tobacco product

Abstract

The invention relates to a heartleaf houttuynia herb and radix isatidis compound extract and application thereof as an additive of a tobacco product. A preparation method comprises the following steps: first adding alkali into an extracting agent, regulating the pH value of the extracting agent to 8.5-10.5, ensuring the weight ratio of the heartleaf houttuynia herb to the radix isatidis to be 10-20:1 and the weight ratio of the extracting agent to the extracting materials to be 5-10:1, carrying out extraction for 1-5h at 50-90 DEG C, concentrating feed liquid until the volume of the feed liquid is 1 / 6 of the original volume after separating out the feed liquid, using AB-8 macroporous resins to separate concentrated liquid, collecting eluant with ethanol concentration of 40-60% and concentrating the eluant into an extract, using 5-10 times of extracting agent to re-dissolve the extract, filtering and separating by-products again and concentrating the feed liquid into an extract again, thus obtaining the extract of the invention. The extract can be added into the cut tobaccos as the additive of the tobacco product, can effectively increase fragrance when the tobacco product is smoked, has rich fragrance, improves firm feel of smoke and can endow the tobacco product with unique note.

Description

technical field [0001] The invention relates to the application of a natural plant extract in tobacco products, in particular to a composite extract of Houttuynia cordata and Radix Radix and its use as an additive for 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 r...

Problems solved by technology

However, only two of the reported research results have been used in traditional Chinese medicine and related products, and there is no literature report on the use of cigarette additives.

And in the process of our research, we found that the simple Houttuynia cordata extract or Radix isatidis extract obtained through the conventional extraction process has a relatively large negative effect and cannot meet the requirements for use as a cigarette additive
