Problems solved by technology

Chinese patent CN 103637395A "A Method for Controlling the Surface Color of Reconstituted Tobacco Leaf by Papermaking Method" adds pigments and brightness additives to the tobacco concentrate, and improves and stabilizes the color of reconstituted tobacco leaves through the pigment control method, but this method requires The introduction of exogenous substances in the product not only brings about product safety problems, but these pigments will precipitate with changes in external conditions such as temperature and block the pipeline during use, affecting product quality; Chinese patent CN 1072071A "A Tobacco Method for improving the color of reconstituted tobacco leaves" provides a method for improving the color of reconstituted tobacco leaves, by adding decolorizing agents such as hydrogen peroxide solution to decolorize reconstituted tobacco leaves to improve the color of reconstituted tobacco leaves
However, these adsorbents have high processing costs and unsatisfactory adsorption effects. Moreover, some key aroma-making substances are inevitably removed while adsorbing substances that are prone to blackening in tobacco, which has a certain negative impact on the sensory quality of the product.

Abstract

The invention discloses a method for improving luster of reconstituted tobacco in a paper-making process. The reconstituted tobacco obtained by the method is luminous yellow. The method includes firstly subjecting tobacco substances to water extraction, concentrating, adding ethyl alcohol with certain concentration into concentrated liquor, insolubilizing polyphenols, protein, pectin and the like of raw materials into alcoholic solution and precipitating, refining water extraction liquor after solid-liquid separation, and optionally sedimentating and pre-removing substances. Optional removal effect is remarkable, and ethyl alcohol has no effect on sensory quality and is lower in boiling point than water so that solvent is easy to recycle.

Description

technical field [0001] The invention relates to the technical field of tobacco. More specifically, it relates to a method for improving the color of reconstituted tobacco leaves by papermaking. Background technique [0002] Reconstituted tobacco leaves, also known as tobacco flakes, use the waste generated during the cigarette process (including tobacco stems, tobacco dust and shredded tobacco leaves) as raw materials, and undergo different processing methods to prepare thin slices close to tobacco leaves. These thin slices can be reused. in the production of cigarettes. Using tobacco waste to produce tobacco sheets, on the one hand, can maximize the use of tobacco raw materials and reduce the consumption of raw materials in the tobacco industry, thereby reducing costs; on the other hand, it can be improved and enhanced by artificially changing the physical structure and chemical composition of reconstituted tobacco Quality of Tobacco Products. Therefore, the development ...
