Embodiment 1

[0041] Weigh 0.3g of 30wt% β-carotene oil suspension, add 1g of emulsifier: Tween 80 for grinding, and then add 8.9g of distilled water to prepare to obtain a water-soluble β-carotene with a mass fraction of β-carotene of 0.88% white.

[0042] 1g water-soluble beta-carotene, 0.1g variable valence metal salt: ferrous sulfate and 8g hydrogen peroxide (mass percentage concentration of 30%) were added to 100g concentrated solution successively, and the stirring speed was 300 rpm at 50°C. After stirring and reacting under different conditions for 30 minutes, a coating liquid sample 1# was prepared. The concentrated solution is the concentrated solution obtained after the tobacco extract is concentrated, and the density of the concentrated solution is 1.18 g / cm 3 .

[0043] The above-mentioned coating solution sample 1# was coated on the reconstituted tobacco leaf substrate, and the coating rate was 36%. After drying at 105°C for 5 minutes, it was cut to obtain the desired recons...

Embodiment 2

[0045] Weigh 0.6g of 30wt% β-carotene oil suspension, add 2g of emulsifier (polyglycerol fatty acid ester: Tween 80 = 1:1) for grinding, and then add 7.8g of distilled water to prepare to obtain β-carotene. The mass fraction is 1.73% water-soluble beta-carotene.

[0046] Add 0.4g water-soluble β-carotene, 0.2g variable valence metal salt: copper sulfate and 8g hydrogen peroxide (27% by mass) to 100g concentrated solution successively, at 60°C, the stirring speed is 400 rpm / After stirring and reacting under different conditions for 40 minutes, a coating liquid sample 2# was prepared. The concentrated solution is the concentrated solution obtained after the tobacco extract is concentrated, and the density of the concentrated solution is 1.18 g / cm 3 .

[0047] The above-mentioned coating solution sample 2# was coated on the reconstituted tobacco leaf substrate, and the coating rate was 36%. After drying at 105°C for 5 minutes, it was cut to obtain the desired reconstituted to...

Abstract

The present invention provides a method for preparing a coating liquid for increasing the content of dihydrokiwifruit lactone and a corresponding coating liquid. The present invention further provides a preparation method of reconstituted tobacco leaves with increased dihydrokiwifruit lactone content and corresponding reconstituted tobacco leaves. The present invention provides a method for preparing reconstituted tobacco leaves with increased dihydrokiwifruit lactone content, wherein β-carotene is oxidized and degraded by artificial means, the dihydrokiwifruit lactone content in the reconstituted tobacco leaves is directly increased, and the sensory quality of the reconstituted tobacco leaves is improved, It has not been reported in the prior art.

Description

technical field [0001] The invention belongs to the field of reconstituted tobacco leaves by a papermaking method, and relates to a preparation method of the reconstituted tobacco leaves which can increase the content of dihydrokiwifruit lactone. Background technique [0002] The aroma of dihydrokiwifruit lactone is relatively light and elegant, and it is an important neutral component of tobacco leaf aroma. Its aroma threshold is low, and the aroma of tobacco leaves is greatly affected when its content changes slightly. β-Carotene is a plant pigment contained in tobacco itself, and it is also the precursor of dihydrokiwifruit lactone, an aroma component of tobacco leaves. β-Carotene contains many conjugated double bonds and is easily degraded by external environmental conditions such as light, temperature, humidity, etc. However, natural degradation requires a long period, many influencing factors, and the process is not easy to control. At present, the prior art lacks a...
