Method for preparing tobacco sheet based on paper making technique and application thereof

Abstract

The invention discloses a method for preparing tobacco sheets based on the paper making technique and an application of the method. In the method, the tobacco materials are soaked and extracted, solid-liquid separation is implemented, the solids are made into fiber sheet substrates, the liquid is made into concentrated solution by alcohol precipitation and concentration, reducing sugar and amino acid are added in the concentrated solution to implement Maillard reaction to make coating liquid that is coated on the fiber sheet substrates, and the fiber sheet substrates are dried and cut into tobacco sheets. The invention adds Maillard reaction in the conventional method for preparing tobacco sheets based on the paper making technique, and obtains tobacco sheets in different aromas accordingto different compatible solutions of reducing sugar and amino acid so as to fit cigarette products in different aromas. The tobacco sheets prepared by the method have excellent compatibility and harmony with the cigarette raw materials, have the capability of effectively decreasing the tar release quantity and the contents of the total particle substances in the main taste, and have the advantagesof good cigarette taste, various and rich aromas and less impure taste.

Description

technical field [0001] The invention relates to the technical field of tobacco sheet preparation, in particular to a method for preparing tobacco sheet based on a papermaking method and its application. Background technique [0002] Cigarette industry regenerated tobacco sheet is the waste produced in the cigarette processing process, discarded tobacco stems, tobacco leaves and inferior tobacco leaves, through different processing, and then into recombined tobacco leaves with high economic added value and special usability for cigarettes. This technology is a high-tech with the concept of green environmental protection and significant social and economic benefits, which fills the gap in the cigarette industry's utilization of "full tobacco leaves and entire tobacco stems". [0003] At present, there are three main methods of producing tobacco sheets at home and abroad: roll pressing method, thick pulp method and papermaking method. Among them, the papermaking method tobacco ...

[0005] Chinese patent CN 1274548A discloses "A Method for Producing Tobacco Sheets Using Waste from Tobacco Factory" and CN 1324586A discloses "Method for Producing Tobacco Sheets Using Waste and Low-grade Tobacco Raw Materials at Full Price", which provide a combination of tobacco powder and After the water-soluble substances in the tobacco stems are extracted and separated from the solid and liquid, the solid part is made into a paper base after being pulped, and the liquid part is concentrated and then coated on the paper base. During the physical recombination process of raw materials, the macromolecular compounds in the concentrated extract hardly undergo transformation during the preparation process, resulting in tobacco flakes having flavor absorption defects such as poor taste quality, heavy miscellaneous gas, strong irritation, and unpleasant taste. Affects the use effect and addition amount of flakes in cigarette products

However, in this method, the content of cellulose such as lignin in the tobacco sheet is relatively high, resulting in a heavier woody gas and greater irritation in the sheet; incomplete conversion of macromolecular substances, resulting in poor coordination of the internal chemical components of the sheet; The content of nicotine is low, which leads to the disadvantages of weak smoke taste, strong irritation and rough smoke
