Problems solved by technology

At the same time, if the extraction and concentration process is handled well, it will not only benefit the physical and chemical indicators and smoking quality of reconstituted tobacco leaves by papermaking method, but also have a beneficial impact on the subsequent pulping and papermaking processes.
However, the technical effect of the existing extraction and concentration process is still unsatisfactory

Embodiment 1

[0021] Weigh 1 part of acid protease, 1.5 parts of compound pectinase, 0.5 part of compound neutral cellulase and 0.1 part of neutral lipase. The raw materials are placed in 90 parts of water, mixed and stirred for 13 minutes, filtered, and the clear liquid is taken to obtain the modified additive for reconstituted tobacco leaves of the present invention. Mix 0.1 part of modified additive with 1.8 parts of water evenly, then add 1 part of tobacco stem raw material, keep the temperature at 35°C, and let it stand for 2 hours; then add 1.2 parts of water, and then soak and extract at 70°C for 20 minutes After the extraction, the solid and liquid are separated, the liquid part is concentrated in vacuum, the solid part is beaten and sliced, the concentrated solution is applied back to the film base, dried, and cut into slices to obtain the required finished reconstituted tobacco leaves.

Embodiment 2

[0023] Repeat Example 1, with the following differences: Weigh 2 parts of acid protease, 2 parts of compound pectinase, 0.75 part of compound neutral cellulase, and 0.5 part of neutral lipase. The raw materials are placed in 95 parts of water, mixed and stirred for 15 minutes, filtered, and the clear liquid is taken to obtain the modified additive for reconstituted tobacco leaves of the present invention.

Embodiment 3

[0025] Repeat Example 1, with the following differences: take 3 parts of acid protease, 3 parts of compound pectinase, 1 part of compound neutral cellulase, and 1 part of neutral lipase. The raw materials are placed in 100 parts of water, mixed and stirred for 17 minutes, filtered, and the clear liquid is taken to obtain the modified additive for reconstituted tobacco leaves of the present invention.

Abstract

A modifying additive for preparing the tobacco leaf sheet by paper-making method is prepared through proportionally adding acidic proteinase, composite pectase, composite neutral cellulase and neutral lipase in water, stirring, filtering and taking clear liquid. It can be used to treat tobacco stems for improving the flavouring component in liquid extract and the physical properties of tobacco stem and the looseness of tobacco leaf sheet.

Description

technical field [0001] The invention belongs to the technical field of reconstituted tobacco leaves, and in particular relates to a modified additive capable of effectively improving the smoking quality of reconstituted tobacco leaves by a papermaking method. At the same time, the present invention also relates to a method for preparing and using the modified additive. Background technique [0002] At present, the use of paper-making reconstituted tobacco leaves is becoming more and more common in the world tobacco industry, mainly because paper-making reconstituted tobacco leaves have advantages that other types of reconstituted tobacco leaves cannot match: such as good filling performance, good physical and mechanical properties, and human intervention. Strong, low tar content, easy to store and transport. The raw materials used in papermaking reconstituted tobacco leaves are mainly tobacco waste, about 50% of which are tobacco stems. Since the tobacco stem itself contai...
