Abstract

The invention discloses an extraction method of cigar tobacco leaf essential oil, which comprises the following steps: shredding cigar tobacco leaf leftovers, adjusting the water content, standing at room temperature, freezing at -5 to -10 DEG C for 2-6 hours, drying to constant weight, crushing and sieving, spraying an enzymolysis solution on the surface of the cigar tobacco leaf leftovers, and then performing enzymolysis and high-temperature inactivation to obtain enzymolyzed tobacco leaves; adding the enzymolyzed tobacco leaves into a tubular furnace, heating to 120-160 DEG C under the protection of nitrogen, keeping the temperature for 1-2 hours, slowly cooling to room temperature, and grinding to obtain pre-crushed cigar tobacco leaves; adding the pre-crushed cigar tobacco leaves into an ultrasonic extraction tank, adding an organic solvent, soaking, carrying out ultrasonic extraction, and collecting an extracting solution a; adding an organic solvent into the residual material residues, performing ultrasonic extraction, and collecting an extracting solution b; and combining the extracting solution a and the extracting solution b, concentrating under reduced pressure, keeping the vacuum pressure of the system at 1-1.5 kPa, and collecting fractions with the boiling point lower than 175 DEG C to obtain the cigar tobacco leaf essential oil. Waste in the cigar processing process is turned into wealth, the extracted essential oil is pure natural tobacco homologous perfume, and the defect that tobacco products are insufficient in fragrance is effectively overcome.

Description

technical field [0001] The invention relates to the technical field of tobacco leaf essential oil, in particular to a method for extracting cigar tobacco leaf essential oil. Background technique [0002] Tobacco combustion produces a large amount of tar, which is harmful to human health, and many characteristic aroma substances in tobacco mainly exist in tar. If the tar content in cigarettes is reduced, the smell of smoke will inevitably be weakened, and the aroma will become lighter, thus making cigarettes Lost original style. Then how to reduce the tar content of cigarettes while still retaining the flavor of cigarettes, so as to improve the experience of smokers, has become an important issue in cigarette production. [0003] At present, the main solution is to add flavor enhancers to make up for the lack of fragrance, and cigar tobacco leaf extract, as a natural spice, is the most ideal flavor enhancer. Cigar tobacco leaf essential oil is a mixture of many compounds, ma...
