Embodiment 1

[0024] A method for extracting tobacco spices from tobacco branches by supercritical fluid extraction technology, comprising the following steps:

[0025] Step 1: Collect the tobacco branches in time after wiping the branches in the field, and filter out the foreign matter.

[0026] Step 2. Pretreatment of different types of tobacco: the flue-cured tobacco branches are dried at a low temperature of 40-60° C., and the burley tobacco branches and cigar tobacco branches are dried in a ventilated room. In this step, the temperature of the flue-cured tobacco branch drying refers to the temperature settings of the three stages of the initial curing of the flue-cured tobacco, that is, the yellowing period, the color fixing period, and the tendon drying period, simulating the conditions of the initial curing of the flue-cured tobacco and the modulation of burley tobacco and cigars , Promote the formation of aroma substances in raw materials.

[0027] Step 3, crushing the sterilized t...

Embodiment 2

[0033] Collect the flue-cured tobacco smeared by Daejeon, and screen out the foreign matter. Bake at a low temperature of 50°C for 8 hours, crush and select samples between 20 mesh and 40 mesh sieve. Fill the sample into a supercritical extraction kettle, extract statically for 0.5 h under conditions of extraction temperature 45° C. and extraction pressure 300 bar, and then perform dynamic extraction for 2 h. The flow rate of carbon dioxide during dynamic extraction is 2 L / min. A light yellow semi-solid extract was obtained with an extraction rate of 3%. The aroma components of the extract were analyzed, and the results are shown in Table 1.

Embodiment 3

[0041] The flue-cured tobacco branch extract obtained in Example 2 was added to the flue-cured tobacco sheet coating liquid at a weight ratio of 40%, and the sensory evaluation effect of the prepared sheet was compared with the original sheet without adding it, which increased the aroma of tobacco and improved compatibility . The sheet product is added to a brand of flue-cured tobacco at a ratio of 10% by mass to obtain a cigarette product with an ideal smoking effect.

Abstract

The invention discloses a method for extracting a tobacco flavor from tobacco forks by use of a supercritical fluid extraction technique. The method comprises the following steps: preprocessing tobaccos of different types and crushing the preprocessed tobacco forks to the range of 10-80 meshes; adding the crushed samples to a supercritical fluid extraction kettle and adding an entrainer having the concentration of 60%-100%; performing carbon dioxide supercritical fluid extraction at an extraction temperature of 40-65 DEG C and under an extraction pressure of 200-350bar; adding the tobacco fork extracts to cut stems in the ratio of 0.005-0.05% of the weight of the tobaccos by the tobacco types, or adding to a slice coating liquid in the ratio of 30%-70% to prepare tobacco slices, or directly adding in the ratio of 0.1%-1% to prepare the tobacco slices; and adding the cut stems or the slices to a cigarette formula in the proportion of 2%-15%, thereby preparing into cigarette products. The method is capable of remitting the insufficiency of raw materials, and also reducing the pollution to the environment and avoiding the waste of resources.

Description

technical field [0001] The invention relates to the technical field of tobacco waste recycling, in particular to a method for extracting flavors for tobacco from tobacco branches by using supercritical fluid extraction technology. Background technique [0002] my country is a big tobacco producing country, ranking first in the world in terms of planting area and output of tobacco plants. The annual output of tobacco leaves in my country reaches about 2.5 million tons, of which a large amount of low-grade tobacco leaves, tobacco powder and other leftovers are discarded and cannot be used for tobacco leaf production. , can be roughly divided into two major aspects of tobacco agriculture and industry. Tobacco agricultural waste includes field top leaves, foot leaves, fireworks, tobacco branches, axillary buds, low-grade tobacco leaves, tobacco stems, tobacco roots, etc., accounting for about 15% of tobacco leaf production. According to the requirements of the national tobacco ...
