A kind of preparation method of low alkaloid burley tobacco extract

Abstract

The invention provides a preparation method of low-alkaloid burley tobacco extract. According to the low-alkaloid burley tobacco extract, burley tobacco is taken and added into water of 5-10 times volume to be heated till boiling backflow is carried out two times, and burley tobacco crude extract is extracted and obtained; large-particle impurities are filtered away through gauze; then after filter liquor obtained after rough filtering is filtered again through a filtering film, the filter liquor and activated macroporous resin particles special for alkaloid extraction are mixed according to the mass ratio of (5-10):1, and stirring is carried out for 30 min to 60 min at the speed ranging from 20 turns / min to 40 turns / min; and then after gauze is adopted for filtering, a filtering film is used for filtering, concentration is carried out, and the low-alkaloid burley tobacco extract is obtained. According to the preparation method, the adsorption character of macroporous resin is utilized for reducing the content of alkaloid in the burley tobacco crude extract, and safe, low-alkaloid and high-quality tobacco flavor can be obtained.

Description

technical field [0001] The invention belongs to tobacco extracts, in particular to a method for preparing low-alkaloid burley tobacco extracts by using macroporous resin adsorption technology. technical background [0002] Burley is one type of tobacco. It belongs to the genus Nicotiana of the Solanaceae family and is a type of N. tabac-un. Because the stems and veins of Burley tobacco are milky white, it is more accurate to call it White Burley tobacco (White Burley). In the 1950s, my country began to introduce trial planting, and in the 1980s and 1990s, Hubei, Chongqing and other places had large-scale planting. However, compared with the quality of imported tobacco, domestic burley tobacco still has a large gap in sensory quality. In terms of chemical composition, the alkaloid content of domestic burley tobacco is much higher than that of imported burley tobacco, which has reached more than 6%, which is more than twice that of imported burley tobacco. Among them, the a...

Problems solved by technology

However, it is unrealistic to process large quantities of extracts, especially in the application of Burley tobacco extracts in cigarettes, and the single batch to be processed can reach hundreds of kilograms or even tons of weight; moreover, from an economic point of view Look, the low output of macroporous adsorption resin column is also not applicable to Burley tobacco extract. Therefore, the purification of macroporous adsorption resin technology is only carried out in the laboratory research stage, but not actually applied in production.
