Abstract

The invention discloses a rhododendron latoucheae extractive and a preparation method thereof as well as an application to cigarettes. The preparation method comprises the following steps of: cleanly washing plants and then drying the rhododendron latoucheae; crushing the plants and extracting in water to obtain an extracting solution, wherein the weight ratio of the rhododendron latoucheae to the water is 1: (20-50); after the extracting solution is cooled, centrifuging and carrying out vacuum filtration; concentrating a filtering solution in vacuum until the filtering solution is 1 / 30-1 / 10 of the volume of the extracting solution, so as to obtain a concentrated solution; adding ethanol with the volume percent of 95-100% into the concentrated solution to lead the volume percent of the ethanol in the system to reach to 75-90%; agitating and standing for 8-12 hours; centrifuging and collecting sediments; freezing and drying the sediments to obtain the rhododendron latoucheae extractive. The method provided by the invention has the advantages of simplicity in operation and low cost, and is applicable to industrial production. The prepared rhododendron latoucheae extractive is applied to the cigarettes so that a smoke shape is good when the cigarettes are smoked, the aroma quality is improved and the aroma amount is increased, the drying feeling is reduced, the comfort level and the like are enhanced, the brightness is obviously improved and the smoke fragrance is special.

Description

technical field [0001] The invention relates to the field of extract and its preparation and application, in particular to an extract of rhododendron japonicus, its preparation method and its application in cigarettes. Background technique [0002] Cigarette flavoring and moisturizing technology has always been the key to highlighting the characteristic aroma and personalized style of tobacco products. Moisturizing performance is an important factor affecting the aroma, flavor and smoking comfort of cigarettes. It is an important basis and basis for building the core technology of Chinese cigarettes. Assure. At present, the moisturizing performance of cigarettes is mainly improved by adding propylene glycol, glycerin and other substances as humectants in China, but the moisturizing effect is not obvious enough, and there are still problems such as rapid water dispersion, low smoke moisture, and high irritation. my country, such as Zhejiang Province, is rich in characteristi...
