Embodiment 1

[0028] 1) Accurately weigh 100g of stem sticks, leaching with water for 50min at a material-to-liquid ratio of 1:6 and a temperature of 50°C, and filter to obtain tobacco stem extract.

[0029] 2) Enzymatic hydrolysis of the tobacco stem extract: add 0.3g of neutral cellulase with an activity of 100,000U / g to 100g of tobacco stem extract, 0.4g of pectinase with an activity of 50,000U / g, and an activity of 100,000U / g of papain 0.3g. The order of adding the enzyme preparations is as follows: add the neutral cellulase and pectinase and react for 1.5 hours at the same time, then add papain and react for 1.0 hours. The enzymatic hydrolysis conditions of the tobacco stem extract are: temperature 45°C, pH natural. After the enzymolysis is completed, the extract is subjected to enzyme inactivation treatment, and the enzyme inactivation conditions of the tobacco stem extract are: water bath inactivation, the temperature is 95-100° C., and the time is 10 minutes.

Embodiment 2

[0043] 1) Accurately weigh 100g of stem sticks, leaching with water for 50min at a material-to-liquid ratio of 1:6 and a temperature of 50°C, and filter to obtain tobacco stem extract.

[0044] 2) Enzymatic hydrolysis of the tobacco stem extract: add 0.25g of neutral cellulase with an activity of 100,000U / g to 100g of tobacco stem extract, 0.5g of pectinase with an activity of 50,000U / g, and an activity of 100,000U / g of papain 0.2g. The order of adding the enzyme preparations is as follows: after neutral cellulase and pectinase are simultaneously added to react for 1.0 h, then papain is added to react for 1.0 h. The enzymatic hydrolysis conditions of the tobacco stem extract are: temperature 45°C, pH natural. After the enzymolysis is completed, the extract is subjected to enzyme inactivation treatment, and the enzyme inactivation conditions of the tobacco stem extract are: water bath inactivation, the temperature is 95-100° C., and the time is 10 minutes.

Abstract

The invention relates to a processing method for improving the quality of a tobacco stem extract, comprising the following steps: adding an exogenous enzyme into the tobacco stem extract to carry out enzymolysis; filtering and concentrating the tobacco stem extract subjected to enzymolysis; adding an ammonium salt into the concentrated tobacco stem extract, and fully dissolving the ammonium salt. Because the exogenous enzyme is added into the exogenous enzyme to carry out enzymolysis, the large-molecule compound in the tobacco stem extract, which is not good for the smoking quality, is degraded into the beneficial small molecular substances. The ammonium salt added into the concentrated tobacco stem extract can be subjected to Maillard reaction with the saccharides in the tobacco stem extract during the combustion of the cigarette. The concentrated solution can be used for the cut tobacco stem to improve the quality of the cut tobacco stem significantly and improve the utilization rate of the cut tobacco stem in the cigarette.

Description

【Technical field】 [0001] The invention belongs to the field of tobacco processing methods, and relates to a method for processing tobacco stem extracts, in particular to a processing method for improving the quality of tobacco stem extracts and the sensory quality of shredded stems. 【Background technique】 [0002] Tobacco stems are the thick, hard veins of tobacco leaves that are shredded and added to cigarettes. In high-end cigarette production enterprises, because the content of cell wall substances in tobacco stems that are not conducive to smoke, flavor and combustibility is relatively high, the added amount is very small and cannot be fully utilized. But tobacco stems are rich in a variety of chemical components, many of which can still be reused. [0003] In the prior art, most of the tobacco stems are directly processed, but due to the dense structure of the tobacco stems, the effect of using exogenous enzyme preparations to directly treat the tobacco stems is not si...
