Method for improving quality of cut stems by aspartic acid based solid-phase Maillard reaction

Abstract

The invention aims to provide a method for improving quality of cut stems by aspartic acid based solid-phase Maillard reaction. According to the method, in the charging production procedure of cut stems, water solution containing amino acids(aspartic acid and asparagine) and reducing sugar or complex carbohydrate source and reaction catalyst at a certain ratio is sprayed to cut stems; in the online process of the cut stems, aspartic acid based solid-phase Maillard reaction is carried out; thus, type and content of aroma components of the cut stems are increased, curing fragrance is enhanced, smoke stimulation and offensive odor are reduced, smoke is purified, smoking flavor is improved, organoleptic quality of the cut stems is improved, the cut stems processed by the method have appearance close to the high-quality cut tobacco, and the method needs mild processing conditions which are easy to realize.

Description

technical field [0001] The invention relates to the field of tobacco processing, in particular to a method for improving the quality of cut stems by aspartic acid solid-phase Maillard reaction. Background technique [0002] Tobacco is a plant of the genus Nicotiana in the family Solanaceae. The tobacco stem is the thick and hard vein of the tobacco leaf, accounting for about 25-30% of the leaf weight. Tobacco stems are by-products of the tobacco industry and are mostly disposed of at present. my country is a big tobacco country, and hundreds of thousands of tons of tobacco stem resources are discarded every year, which not only causes environmental pollution, but also wastes natural resources. Studies have shown that the types of components contained in tobacco stems are basically the same as those of tobacco leaves. Shredded stems have the characteristics of low tar and nicotine content and good filling performance. They are one of the main fillers in cigarette leaf formu...

Problems solved by technology

Invented "a method for improving the quality of cut stems" (application number: 201410002912.2). When washing the stems, the tobacco stems are soaked or washed with a circulating protease aqueous solution, and the compound enzyme solution (compound enzyme by fruit Gelase, cellulase and xylanase) are sprayed on thick stalks and stored for more than 6 hours; additives (additives refer to amino acid solutions selected from glutamic acid, phenylalanine, aspartic acid, Proline or a combination thereof) is applied to the stalks in a ratio of ≥1%, and stored at room temperature for more than 0.5 hours, which has defects such as complex process, high process cost, and long time-consuming process, and the Maillard reaction time is short, The reaction temperature is low, there is no reaction catalyst and stabilizer, it is only 0.5h at normal temperature, the reaction is not sufficient, and the aroma-enhancing effect of the Maillard reaction product is not good; invented "a processing method for improving the quality of cut stems" (application number: 201510041600.7 ), first extract the tobacco stem or stem piece with alcohol solution, and then add the alcohol extract back to the shredded stem made of the tobacco stem or stem piece, and wash the tobacco stem with acid hydrolysis and enzymatic hydrolysis macromolecules (like pectin, protein, etc.) and other compounds that are unfavorable to tobacco smoking, but the alcohol crude extract of tobacco stems still has the defects of high irritation, high concentration, obvious miscellaneous gas, and insufficient aroma; In the silk online production process, the method and application of aspartic acid, asparagine and reducing sugar / complex sugar source solid-phase Maillard reaction to improve the quality of cut stems have not been reported yet.
