Embodiment 1

[0037] Embodiment 1: preparation

[0038] The obtained sophorolipid is obtained by fermenting and culturing Wickerhamiella domercqiae for 5 days at 30° C. and 220 rpm. Wherein the fermentation medium consists of: glucose 6wt%, Na2HPO 4 12H 2 O 0.1wt%, MgSO 4 ·7H 2 O0.05wt%, KH 2 PO 4 0.1wt%, oleic acid 6wt%, yeast powder 0.3wt%; then the fermentation broth was extracted with twice the volume of ethyl acetate, and the upper organic phase was distilled under reduced pressure at 50°C and washed twice with n-hexane, then decompressed at 50°C pressure distillation to obtain a light yellow blocky solid, which is the lactone-type sophorolipid; the lower aqueous phase is vortex mixed with twice the volume of ethanol, centrifuged to take the supernatant, washed twice with n-hexane after vacuum distillation, and then washed for 50 °C and dried under reduced pressure to obtain a dark brown viscous liquid, which is the acid type sophorolipid.

Embodiment 2

[0039] Example 2: Application

[0040] 1. Moisture-proof and moisture-proof experiment

[0041] The lactone-type sophorolipid and the acid-type sophorolipid prepared in Example 1 were added to shredded tobacco at a ratio of 0.1% by mass of shredded tobacco, and shredded tobacco samples added with equal amounts of propylene glycol and glycerin were used as controls. Then, divide the treated cut tobacco samples into two parts, place them in constant temperature and humidity chambers at 22°C, RH 40% and 22°C, RH 80%, and weigh them once at regular intervals to measure the water content of the cut tobacco within 48 hours. rate changes. Taking time as the abscissa and the moisture content of the sample as the ordinate, draw the moisture content curve of the sample over time. The final moisture content is shown in Table 1 and figure 1 .

[0042]Increase the amount of lactone-type sophorolipids and acid-type sophorolipids to 0.2%, 0.3%, 0.4%, and 0.5%, and keep other operations un...

Abstract

The invention discloses application of sophorolipid. Serving as a microbial source bi-directional humectant having a physical moisture retention damp-proof function and an aroma enhancement function, the humectant is natural, non-toxic and harmless. Sophorolipid comprises any one of lactone type sophorolipid and acid type sophorolipid or mixture of lactone type sophorolipid and acid type sophorolipid. The humectant can be applied to cigarettes, tobacco shreds, tobacco sheets and other tobacco products. The humectant is evenly sprayed on the tobacco shreds, the spraying proportion is 0.05%-2.0% of the weight of the tobacco shreds, and the humectant has effects of obviously retaining tobacco shred moisture under low humidity conditions and obviously controlling moisture increase under high humidity conditions; the moisture retention and dampproof effect is more excellent than that of propylene glycol and glycerin, and the humectant is an excellent natural bi-directional humectant.

Description

[0001] 1. Technical field [0002] The invention relates to the use of a sophorolipid, which is used as a two-way tobacco humectant in tobacco and belongs to the technical field of tobacco moisturizing processing. [0003] 2. Background technology [0004] The smoking quality, safety and price of cigarette products are the main factors that determine whether consumers choose to buy or not. Tobacco moisture retention has an important influence on cigarette processing resistance, cigarette flavor and smoking comfort. The climatic conditions in different regions of my country are quite different. Even under the premise of a certain moisture retention performance, the sensory comfort of cigarettes of the same brand varies greatly at different times and regions. Therefore, it is an urgent problem to be solved in the tobacco industry to find how to obviously control the moisture of shredded tobacco (including improving the water-holding capacity at low humidity and reducing the wate...
