Problems solved by technology

However, this production process is relatively complicated, time-consuming, long production cycle, labor intensive, and the corresponding production costs are relatively high. More importantly, a single precipitation-back-dissolution method cannot solve the problem of rehmannia glutinosa flavors and fragrances that have a large aftertaste residue in cigarettes. Negative impact

Embodiment 1

[0035] (1) After grinding rehmannia glutinosa into powder, take 1 times the weight of rehmannia glutinosa, add 6 times the weight of 40% (volume percentage) ethanol solution, reflux extraction at 120° C. for 3-5 hours, and filter.

[0036] (2) Add 40% (volume percentage) ethanol solution of 6 times the weight of the original medicinal material to the remaining filter residue after step (1) is filtered, continue the reflux extraction at a temperature of 120°C for 4 hours, filter and combine the two The filtrate was obtained to obtain Rehmannia glutinosa extract A.

[0037] (3) First pass the Rehmannia glutinosa extract A through a ceramic membrane with a pore size of 100nm (first-stage membrane), the flow rate is 65L / h, the temperature is controlled below 45°C, the inlet pressure is 2.0MPa, and the outlet pressure is 1.2MPa. When the rehmannia extract A system starts to foam, add 10% water of the total weight of the rehmannia extract to increase the yield of the target product....

Abstract

The invention discloses a method for preparing rehmanniae flavor for cigarette by using the membrane separation technique, belonging to the technical field of cigarette flavor preparation. The method is carried out according to the following steps: carrying out reflux extraction twice, obtaining the filtrate of rehmanniae extract A; filtering by a ceramic membrane with the aperture of 100nm, and obtaining the solution passing through the membrane called a filtrate B; and filtering the filtrate B through an organic spiral-wound membrane with the trapping molecular weight of 25 thousand, obtaining a filtrate C which is the rehmanniae flavor for cigarette. The method is simple, is easily implemented, and uses membrane separation technique to replace the original precipitation remelting method. The invention has the advantages of simple technology, short production period, low cost, remarkable economic benefits, improvement of automazation degree and enhancement of controllability of production technology, and solves the problems of aftertaste and remaining of cigarettes in mouths.

Description

technical field [0001] The invention belongs to the technical field of preparation of cigarette flavors and fragrances, in particular to a method for preparing and producing the flavors and fragrances of Rehmannia glutinosa using membrane separation technology. Background technique [0002] Rehmanniae glutinosa (Gaertn.) Libosch.ex.Fisch.et Mey is the tuber root of Rehmanniae glutinosa (Gaertn.) Libosch.ex.Fisch.et Mey. According to different processing methods, it can be divided into fresh rehmanniae, dry rehmanniae and rehmannia glutinosa. At present, catalpol is used as an indicator substance of fresh rehmannia glutinosa and dried rehmannia glutinosa, and 5-HMF is widely used as an indicator substance of rehmannia glutinosa. Rehmannia glutinosa has the effect of nourishing yin and clearing away heat. Rehmannia glutinosa has the effect of nourishing blood, nourishing yin, nourishing essence and filling marrow. It is an excellent medicine for nourishing yin and blood. , cl...
