However, since most of the reaction raw materials use a single amino acid or a mixture of several amino acids as the amino compound of the reaction raw material, a monosaccharide, disaccharide or a mixture of several monosaccharides is used as the carbonyl source of the reaction. Although different reaction condi

Abstract

This invention is about a method for making essence for tobacco by biological enzymolysising sub tobacco leaves, which contains: After enzymolysising sub tobacco leaves with conjugated cellulase and prolease, eradicate enzyme, filter and concentrate to prepare sub tobacco leaves mixing enzymolysis liquid; Taking the liquid as main nitrogen resource, add aldehyde, propanediol and brown sugar to proceed Melade reaction to prepare essence for tobacco. This invention uses the sub tobacco leaves enzymolysis products í¬í¬ monosaccharides, oligosacchrides, composite amino, acidoligopeptides and polypeptides as main materials, and makes the essence by Melade reaction. This can heighten the total availability ratio of sub tobacco leaves resource, also the reaction product has very obvious functions of excluding cigarette bad smell, reducing excitation, perfuming, coordinating aroma and making the aftertaste of cigarettes pure and comfortable, and it could be used broadly in cigarette industry. Using this method to make essence for tobacco is easy to process and the product quality is stable.

Description

technical field [0001] The invention relates to the field of production of tobacco essence, in particular to a method for preparing tobacco essence through biological enzymolysis of low-grade tobacco leaves. Background technique [0002] The invention relates to flavoring essence for tobacco, in particular to a method for producing flavoring essence for tobacco using low-grade tobacco leaves as raw materials. In addition, the present invention also relates to the use of biotechnology enzymatically decomposing low-grade tobacco leaves, protease degrading low-grade tobacco leaf protein to process raw materials, and strengthening the characteristics of tobacco flavor through Maillard reaction. This method uses propylene glycol solution as the basic reaction medium. [0003] The Maillard reaction is a reaction between carbonyl compounds generated by oxidation of aldehydes, ketones, reducing sugars or fats and amino groups in amines, amino acids, peptides, proteins and even ammo...
