Description

Technical Field

[0001] The invention relates to the technical field of reconstituted tobacco, and in particular to a method for preparing watermelon ice style reconstituted tobacco. Background Art

[0002] Edible watermelon flavor is a food additive that gives watermelon food a natural flavor. The aroma of watermelon is very weak and has two odors, the rind and the flesh. The aroma is sweet and green, somewhere between melon and cucumber. The main aroma components of watermelon are alcohol, aldehyde and ester. There are more than 30 known, but not all have been identified. The main components of watermelon aroma are as follows:

[0003] Alcohols: methanol, ethanol, butanol, pentanol, 3-hexenol, 2-octenol, nonanol, trans-2-nonenol, cis-6-nonenol, 3-nonenol, 2,6-nonadienol, benzyl alcohol;

[0004] Aldehydes: acetaldehyde, isovaleraldehyde, hexaldehyde, trans-2-hexenal, trans-2-heptenal, trans-2-octenal, nonanal, trans-2-nonenal, cis-6-nonenal, 2,6-nonadienal, trans-2-decenal, citral, 3,6-nonadienal;

[0005] Esters: Isopropyl acetate, Methyl valerate, Ethyl decanoate, Benzyl acetate, Methyl benzoate

[0006] Ketones: acetone, ethylionone, raspberry ketone.

[0007] Watermelon ice is a refreshing summer drink among fruit drinks. It has a distinct style. Reconstituted tobacco with the style of watermelon ice has not been reported. When mixing watermelon flavor, the first thing to consider is to use fruit and vegetable spices, and then supplement with green and sweet fragrance materials. Use some fruity raw materials and some natural spices to enrich and set off the fragrance and aroma of the entire flavor, which plays a rounding and modifying role. According to the aroma components of watermelon, watermelon flavor is mainly divided into four major aromas, namely: characteristic watermelon green fragrance, fruity fragrance, slightly oily green fragrance and sweet flesh fragrance.

[0008] After analyzing the approximate composition of each aroma segment, it was determined that the top note accounts for 15% to 30% of the watermelon essence, the body note accounts for 60% to 70%, and the base note accounts for 10% to 25%.

[0009] Through the innovation of technology and methods, the watermelon ice style characteristics are presented on the reconstituted tobacco leaves, giving the reconstituted tobacco leaves an aroma characteristic different from the traditional tobacco characteristics, which has a positive effect on broadening the reconstituted tobacco leaf product technology and enriching the category of cigarette products. Therefore, this application proposes a method for preparing watermelon ice style reconstituted tobacco leaves, which can make the reconstituted tobacco leaves have the fragrance of watermelon, the sweet fragrance of melon pulp, and a fresh and comfortable cool feeling.
