Method for manufacturing low-nicotine reconstituted tobacco leaves by taking Maryland tobaccos as raw materials

Abstract

The invention provides a method for manufacturing low-nicotine reconstituted tobacco leaves by taking Maryland tobaccos as raw materials. The low-nicotine reconstituted tobacco leaves are manufactured by the following steps: mixing tobacco leaf fragments or powder of the Maryland tobaccos with water, and adding a mixture into a raw material extracting tank; controlling the temperature to be 25 DEG C to 50 DEG C; then adding a compound enzyme preparation for extracting; adding tobacco stems of the Maryland tobaccos and water into another raw material extracting tank; controlling the temperature to be 65 DEG C to 75 DEG C and carrying out water extraction; after combining a tobacco leaf extracting solution and a tobacco stem extracting solution, putting a mixed solution into a concentration tank; adding propylene glycol, reducing sugar, amino acids and sodium carbonate and decompressing and concentrating at the temperature of 70 DEG C to 90 DEG C to prepare a coating solution; after mixing and pulping a tobacco leaf extracting solid substance and a tobacco stem extracting solid substance, papermaking to obtain a reconstituted tobacco leaf substrate; coating the coating solution on the reconstituted tobacco leaf substrate and drying to prepare the low-nicotine reconstituted tobacco leaves. According to the method provided by the invention, macromolecular substances including proteins, pectin and the like in the Maryland tobaccos are reduced; a biochemical reaction is combined and aroma and quality are improved; the high-tobacco-aroma and low-nicotine reconstituted tobacco leaves are prepared.

Description

technical field [0001] The invention relates to a production method of reconstituted tobacco leaves by the papermaking method in the tobacco industry, in particular to a method for producing tobacco spices by implementing alcohol-liquid extraction, material-liquid separation, and liquid recovery. The raw material part is transformed by biochemical technology to produce low nicotine content. reconstituted tobacco leaves. Background technique [0002] Maryland tobacco is a light-colored air-cured tobacco, which belongs to Safflower tobacco. It is a light-colored air-cured tobacco with a moderate taste. It has been planted in Maryland, USA for more than 350 years, hence the name. Many countries use Maryland tobacco as a raw material for pipe tobacco, chewing tobacco, snuff and cigarettes. In China, it is used as a seasoning raw material in the formula of mixed cigarettes and cigars. Maryland tobacco has strong filling power, good smoldering property and medium aroma. When it ...

Problems solved by technology

This kind of process mode has limited effect on reducing the smell of Maryland tobacco, and will cause a serious loss of the aroma of reconstituted tobacco leaves

[0004] The State Tobacco Monopoly Administration requires all cigarette industrial enterprises to continuously improve the development of low-tar cigarettes, but there is a certain contradiction between "low tar, low harm" and "high aroma" of cigarettes. Reducing the amount of tar in cigarettes usually weakens the taste and reduces the aroma. insufficient
