Embodiment 1

[0025] Weigh 100mmol of glucose and 50mmol of glutamic acid and mix them in 100mL of 30% ethanol aqueous solution, adjust the pH of the system to 9.0, heat the reaction in an oil bath at 105°C for 3h, cool the reaction product to room temperature rapidly after the reaction, and filter to remove insoluble matter. Get the first product. The initial product was extracted with 100mL×3 ethyl acetate, the extracts were combined, and after drying with anhydrous sodium sulfate, the organic solvent was removed by rotary evaporation to obtain 0.21g of a brown paste-like small molecule volatile product. The yield was 1.69%.

[0026] The product is dissolved in ethanol to prepare a flavoring solution, which is evenly sprayed on the shredded tobacco according to 0.005% of the weight of shredded tobacco, and rolled into cigarettes after being baked. The results of the smoking test show that the burnt sweetness and baking aroma of the smoke are prominent, the aroma quality is improved, the am...

Embodiment 2

[0028] Weigh 100mmol of glucose and 100mmol of glutamic acid and mix them in 100mL of 50% ethanol aqueous solution, adjust the pH of the system to 9.0, heat the reaction in an oil bath at 105°C for 6h, cool the reaction product to room temperature after the reaction, and filter to remove insoluble matter. Get the first product. The initial product was extracted with 100mL×3 ethyl acetate, the extracts were combined, dried with anhydrous sodium sulfate, and the organic solvent was removed by rotary evaporation to obtain 0.31g of a brown paste-like small molecule volatile product. The yield was 1.89%.

[0029] The product is dissolved in ethanol to prepare a flavoring solution, which is evenly sprayed on the shredded tobacco according to 0.005% of the weight of shredded tobacco, and rolled into cigarettes after being baked. The results of the smoking test show that the burnt sweetness and baking aroma of the smoke are prominent, the aroma quality is improved, the amount of arom...

Embodiment 3

[0031] Weigh 100mmol of glucose and 150mmol of glutamic acid and mix them in 100mL of 50% aqueous ethanol ) , adjust the pH of the system to 9.0, and heat the reaction in an oil bath at 105°C for 6h. After the reaction, the reaction product is rapidly cooled to room temperature, and the insoluble matter is removed by filtration to obtain the initial product. After extracting the primary product with 100 mL×3 ethyl acetate, the separated aqueous phase was removed by rotary evaporation to remove most of the water, and then freeze-dried to obtain 21.5 g of the solid primary product.

[0032] Take 1.0 g of the solid primary product, and use a 2.5cm×100cm Bio-gel P-6 gel column for gel permeation chromatography separation, and use ultrapure water as the mobile phase for elution at a flow rate of 0.5mL / min. When the colored substance flows to the bottom of the column, collect the eluent at a speed of 5 min / tube, and the elution ends when all the colored substances on the column flow...

Abstract

The invention relates to the technical field of flavors for cigarettes, and particularly discloses a preparation method of a glucose / glutamic acid Maillard reaction flavor for cigarettes, which is characterized in that by using glucose and glutamic acid as raw materials, the material ratio, reaction solvent, reaction time, reaction temperature and system pH are controlled, and the products are graded and separated to obtain the low-molecular-weight volatile product capable of effectively improving sensation quality of cigarettes and the high-molecular-weight product with the molecular weight of 3-6kD. The accurate control on the cigarette glucose / glutamic acid Maillard reaction process and the fine after-treatment on the products are performed to obtain the low-molecular volatile products with favorable cigarette perfuming effect and the high-molecular products, thereby implementing fine processing of glucose / glutamic acid Maillard reaction, and enhancing the application value of the reaction products in cigarette perfuming.

Description

[0001] technical field [0002] The invention relates to the field of flavors for tobacco, in particular to a method for preparing flavors for tobacco by utilizing the glucose / glutamic acid Maillard reaction. Background technique [0003] The Maillard reaction is a non-enzymatic browning reaction (Non-enzymatic browning) between an amino compound and a reducing sugar. After a complex process, the reaction finally produces a brown or even black mixture containing various small molecules and polymers, among which High molecular products are also called melanoids (Melanoidins). Maillard reaction can produce a large number of aroma components, which have been used to prepare various flavors, fragrances and flavor enhancers. Because the reaction can be regarded as natural no matter from the reaction or the product, these fragrance groups are recognized as "natural" by international authoritative organizations, so their application has attracted wide attention from all over the w...
