Preparation method of additive agent capable of causing flue-cured tobacco to have fragrance of oolong tea, flavoring as well as application in flue-cured tobacco

Abstract

The invention discloses a method for preparing an additive capable of adding an oolong tea scent to cured tobaccos, a spice and the use of the spice in the cured tobaccos. The preparation method comprises the following steps: weighing100 grams of oolong tea leaves according to a ratio of 0.5-1.5:1.5-4:0.2-8, grinding the oolong tea leaves into powder, and placing the powder an extracting device; setting a temperature of between 20 and 60 DEG C and a pressure of between 10 and 20MPa, adding 400 to 1,000 milliliters of a mixed solvent of ethanol, acetone and water into the extracting device and carrying out 2 to 5 times of static extraction for 3 to 10 minutes each time; and collecting an extract, evaporating the extract to between 100 and 200 milliliters, adding 30 to 80 milliliters of acetone into the extract, standing the mixture at 0 DEGC for 10 to 60 minutes, centrifuging the mixture to remove sediments, taking upper clean liquid, evaporating the upper clean liquid to paste, dissolving the obtained paste with 80 to 150 milliliters of a mixture of propanediol, alcohol and distilled water, adding 0.01 to 0.2 gram of ascorbic acid, 0.01 to 0.1 gram of menthol, 1 to 10 grams of honey into the solution, uniformly mixing the solution and obtaining the additive for oolong tobaccos. The tobaccos made with the additive has the advantages of low tar content, unique and long lasting scent, comfort tea scent and uniform taste.

Description

technical field [0001] The invention relates to a method for preparing an additive for making flue-cured tobacco with oolong tea, a spice, and the application of the spice in flue-cured tobacco. Specifically, the spice is used to make shredded tobacco, filter tip, cigarette paper and the like. Background technique [0002] Oolong tea, especially Tieguanyin, is rich in tea polyphenols, plant alkaloids, amino acids, vitamins and other substances beneficial to the human body. Ordinary tea-flavored flavors and fragrances are mostly extracted from solvents through high-temperature boiling and reflux. Some heat-sensitive antioxidants such as ascorbic acid (VC) and chlorogenic acid in tea are seriously damaged, and contain a lot of protein, pectin, cellulose, etc. Adding directly to shredded tobacco will cause mixed smoke, increased irritation, and increased tar content. Accelerated solvent extraction is used to prepare tea extract. The whole process is carried out under the condi...
