Description

A kind of preparation method of green wrapper

technical field

The invention belongs to the technical field of cigar processing, and in particular relates to a method for preparing a green wrapper.

Background technique

Cigars are one of the important types of products in the tobacco industry, and are currently the key development areas of the tobacco industry. Traditional cigars are composed of three parts, including from the inside to the outside: filler, binder and wrapper. The cigar wrapper is the most expensive part of the cigar leaf, which determines the appearance of a cigar, and its color quality will affect the consumer's judgment on the aroma, concentration and strength of the cigar product. Generally, wrapper tobacco leaves can be divided into seven categories according to the color depth. It is generally believed that green wrapper cigars (DUBELECLARO) have an elegant and soft fragrance, and are less strong and vigorous, and are more acceptable to most people, especially beginners.

In recent years, with the changes in people's consumption levels and patterns and the maturity of the domestic cigar market, cigar consumption is gradually extending from a small number of high-end cigar consumers to the general public, and has attracted more and more attention. Domestic cigar products continue to introduce new ones, and cigar industry enterprises have an increasing demand for diversification of cigar raw materials. As a special wrapper, green wrapper is favored by many cigar consumers, especially young cigar consumers, because of its unique taste and novel appearance. , but domestic cigars do not yet have green wrapper cigars.

At present, the method for preparing green wrapper (patent number is CN111557467) is mainly through three stages of variable temperature drying treatment and ventilation measures: the fresh tobacco leaves after picking are put into the modulation shed, at first the tobacco leaves are slightly withered, and then the temperature is raised and the humidity is removed, so that Tobacco leaves lose water to control the degradation of chlorophyll and the formation of xanthophyll; then increase the temperature in the conditioning shed again to speed up the water loss of the tobacco leaves and fix the green color of the tobacco leaves, and finally increase the temperature in the conditioning shed again until the main veins are fully dry. The green wrapper produced by this method has good appearance quality and soft taste, but requires a long curing time, and the wrapper tobacco leaves are prone to yellowing or even browning during the curing process.

Contents of the invention
