Embodiment 1

[0030] The dried roselle calyx obtained after pre-treatments such as infrared enzyme inactivation, impurity removal, and airing are crushed to 250um to obtain roselle powder. According to the ratio of ethanol: roselle powder (m / m) = 10:1, the ethanol concentration is 75%, using dual-frequency ultrasonic assisted extraction for 30 minutes, ultrasonic power is 600W, ultrasonic frequency is 20KHz / 40KHz combination, cycle speed is 15r / s, work / intermittent ratio is 2s / 1s, extraction temperature is 50°C, and the extraction liquid passes through the aperture Filter through a 63 μm sieve, and concentrate under reduced pressure to 3 times the dry weight of roselle to obtain roselle extract I.

Embodiment 2

[0032] The dried roselle calyx obtained after pretreatments such as infrared enzyme removal, impurity removal, and airing are crushed to 420um to obtain roselle powder, and 95% ethanol is used as an entraining agent in an amount of 20% of the weight of roselle powder. Supercritical extraction: The extraction pressure is 30Mpa, the extraction temperature is 50°C, the separation pressure is 6Mpa, the separation temperature is 60°C, after 120 minutes of extraction, the tincture is separated, which is Roselle Extract II.

Abstract

The invention discloses a method for extracting a roselle extractive and application thereof in cigarettes as well as cigarettes. The extracting method comprises the following steps of: (1) crushing dry roselle calyxes obtained by pre-treating roselle calyxes to a particle size of 150-420 microns so as to obtain roselle powder; and (2) taking the roselle powder obtained in the step (1), and extracting according to a mass ratio of ethanol to the roselle powder of (0.05-15) :1 for 10-180 min at room temperature to 70 DEG C to obtain the roselle extractive. The application of the roselle extractive in the cigarettes is that the roselle extractive obtained by using the extracting method is diluted by using a non-toxic organic solvent without irritating smells and sprayed on the surfaces of flue-cured tobacco leaves. In the cigarettes, the roselle extractive extracted according to the extracting method is added. By using the invention, the smoking quality of the cigarettes can be largely improved, the mouthfeel of the cigarettes can be improved, and values and significances of actual production can be obtained.

Description

technical field [0001] The invention relates to plant extraction and application thereof, in particular to a method for extracting roselle extract and the application of the extract in cigarettes and cigarettes containing the extract of roselle. Background technique [0002] Roselle Hibiscus sabdariffa L. (also known as Roselle), belongs to the Malvaceae Hibiscus genus annual herb, is a traditional medicinal and edible plant, commercially used roselle is mainly the calyx of its flowering period, the appearance is purple, black and bright, Soaked in water bright color, with cranberry-like aroma, sober and pleasant. Traditional medicine believes that roselle calyx has the functions of clearing away heat, quenching thirst, relieving cough and lowering blood pressure. In Egypt, it is widely used to treat diseases of the heart and nerves; Recommended as a fungicide, anthelmintic and hypotensive. In recent years, there have been extensive and in-depth studies and reports on the ...
