Five-carbon/five-carbon monosaccharide-L-menthoxyacetic acid diester compound and preparation method and application thereof

Abstract

The invention discloses a five-carbon / five-carbon monosaccharide-L-menthoxyacetic acid diester compound and a preparation method and application thereof and relates to a monosaccharide diester tobacco humectant. A novel five-carbon / six-carbon monosaccharide-L-menthoxyacetic acid diester compound shown in a formula (1) is prepared by a chemical synthesis method and the moisture preservation, damp resistance and incense slow releasing effects of the compound serving as the tobacco humectant are tested. A test result indicates that the monosaccharide-L-menthoxyacetic acid diester compound plays a role in preserving moisture, resisting damp and slowly releasing incense on tobacco and is a novel tobacco humectant with dual moisture preservation and incense slowly-releasing functions; and (1) in the formula (1), R represents a residue of five-carbon / six-carbon monosaccharide and two L-menthoxy acetyl can be positioned at any two possible positions of five-carbon / six-carbon monosaccharide.

Description

technical field The invention belongs to the field of tobacco technology, and relates to a monosaccharide diester tobacco humectant, in particular to a five-carbon or six-carbon monosaccharide-L-menthoxyacetic acid diester compound, a preparation method and an application thereof. Background technique The moisture retention performance of cigarettes is closely related to the quality of cigarettes, and the research on flavor enhancement and moisture retention technology will be one of the main directions of scientific and technological research and technological innovation in my country's tobacco industry in the next few years. At present, the humectants used in the production of cigarettes in my country are mainly glycerin, propylene glycol, xylitol and other polyhydroxy substances, which mainly rely on their absorption of moisture in the environment to keep the shredded tobacco moist and play a moisturizing role, which belongs to one-way moisturizing Although such humectants...

AI Technical Summary

Problems solved by technology

At present, the humectants used in the production of cigarettes in my country are mainly glycerin, propylene glycol, xylitol and other polyhydroxy substances, which mainly rely on their absorption of moisture in the environment to keep the shredded tobacco moist and play a moisturizing role, which belongs to one-way moisturizing Although this kind of humectant can maintain the moisture content of cut tobacco during processing and improve the processing resistance of cut tobacco, its effect of maintaining the moisture content of finished cigarettes and improving smoking comfort is not really satisfactory

In addition, since this type of polyhydric humectant has no moisture-proof effect, the moisture content of tobacco treated with this type of humectant is greatly affected by the ambient temperature and humidity, that is, in a dry environment, tobacco is easy to lose moisture and cause it to dry. The sensation and irritation are enhanced, and tobacco is easy to absorb moisture in a humid and warm environment, causing it to mold and deteriorate
