Problems solved by technology

However, a large amount of cigarette aroma components are lost while reducing tar, which reduces product quality and cannot meet consumer demand
[0004] Patent CN201510517926.2 provides a method for preparing black tea essence. The method discloses a method for preparing black tea essence. In this method, the tea dregs enzymatic hydrolysis solution undergoes Maillard reaction, and then the reaction material liquid Aspergillus niger and yeast are further carried out. Fermentation treatment, and after Chen Hua treatment to prepare black tea essence, the fermentation uses compound enzymes to enzymatically hydrolyze the tea dregs under acidic conditions. Although this method improves the stability of the Maillard reaction essence, the process is cumbersome and the effect is low. Unexpected, did not solve the problem of reducing tar, reducing harm and flavoring cigarettes

Embodiment 1

[0050] A preparation method of tea essence, comprising the following steps:

[0051] S1. Preparation of tea enzymatic solution: pass Dianhong crushed tea through an 80-mesh sieve, add 100 parts of tea powder and 1500 parts of water, mix well, adjust the pH to 5.0, add cellulase according to 2.5% of the mass of tea powder, and heat at 50°C Constant temperature water bath for 4 hours, adjust the pH to 8.0, add alkaline protease according to 1.5% of the tea powder mass, 50°C constant temperature water bath for 6 hours, to obtain tea powder enzymatic hydrolysis solution;

[0052] S2. Preparation of tea essence: take the enzymolysis solution and adjust the pH to 8, add aspartic acid at a mass ratio of 2% of the enzymolysis solution, and react with 0.3% fructose of the enzymolysis solution for 3 hours at 110° C. The Maillard reaction solution is cooled, centrifuged and filtered to obtain the tea essence.

Embodiment 2

[0054] A preparation method of tea essence, comprising the following steps:

[0055] S1.

Abstract

The invention discloses tea essence, and a preparation method and application thereof. The preparation method of the tea essence comprises the following steps of tea enzymolysis liquid preparation andpreparation of the tea essence through a Maillard reaction. According to the preparation method, the tea essence obtained through control of a specific enzymolysis system and a Maillard reaction system is rich in tea typical flavor; by applying the tea essence to cigarettes, the fragrance of the cigarettes can be improved, irritation to the throat and the oral cavity in the cigarette smoking process is reduced, the residual taste is improved, and the toxic effects of the cigarettes on a human body can be further lowered; through specific alcohol components in the tea essence, the coordinationof the cigarette fragrance can be improved, the turbidity of smoke is relieved, and the flavor of tobaccos is improved; through acid components and ester components, the specific fragrance of the cigarettes can be increased; through aldehyde components, the residual taste of the cigarettes, flow-test smoke and the like can be improved; and through the specific synergistic effects of the alcohol components, the acid components and the aldehyde components, the fragrance in the essence is mellower, and the tea essence can be widely applied to the field of flavor regulating adding of the cigarettes.

Description

technical field [0001] The invention relates to the technical field of production of heat-reaction essence for tobacco, and more specifically relates to a tea essence and its preparation method and application. Background technique [0002] China is the first country to discover and utilize tea. In my country, tea planting, tea making, and tea drinking have a long history, which can be traced back to 2737 BC. Lu Yu of the Tang Dynasty described in "The Classic of Tea": "The tea maker is also the best wood in the south." The tea is fragrant and delicious, and drinking it often prolongs life, so it can be called "national drink". At the same time, Chen Zangqi recorded in "Supplements to Materia Medica": "All medicines are the medicine of each medicine, and tea is the medicine of ten thousand medicines." It can be seen that tea has been a plant with both food and medicine since ancient times. Tea is not only one of the three major beverages in the world, but also studies ha...
