Abstract

The invention provides a preparation method of gillyflower extract for cigarettes. The preparation method comprises the following steps: (1) adding water into dried gillyflowers for microwave extraction to obtain a gillyflower extracting solution; (2) taking sodium alginate as a carrier and embedding to prepare immobilized beta-glucosidase; (3) treating the gillyflower extracting solution by utilizing the immobilized beta-glucosidase; (4) filtering an extracting solution subjected to enzyme treatment and decompressing and concentrating a filtered gillyflower extracting solution; collecting a concentrated solution to obtain gillyflower extract A for the cigarettes; and (5) carrying out molecular distillation on the gillyflower extract A for the cigarettes to obtain the gillyflower extract. According to the preparation method, the extracting yield of aromatic substances in the gillyflowers is greatly increased and a special aromatic raw material for the cigarettes, which has more abundant aroma and better quality, is obtained; the gillyflower extract has a pleasant flower fragrance; and the gillyflower extract is added into the cigarettes and has the effects of enriching cigarette aroma and increasing sweet aroma.

Description

technical field [0001] The invention relates to the technical field of preparing tobacco extracts, in particular to a preparation method of tobacco violet flower extracts. Background technique [0002] With the continuous improvement of people's consumption level, the demand for high-quality cigarettes is also increasing, but the production of high-quality cigarettes is limited due to the limited output of high-quality raw materials. At present, producers mainly solve the problem of shortage of high-quality raw materials by adding flavors and materials to enhance the aroma of tobacco, improve the quality of tobacco leaves, and increase the utilization rate of tobacco leaves. In cigarette products, the aroma and taste of cigarettes are very important. Adding spices is a key link in the cigarette industry and one of the effective means to improve product style and aroma quality of cigarettes. The traditional method of adding flavors to cigarettes is to mix natural extract mon...
