Embodiment 1

[0052] The embodiment of the present invention provides a preparation method of longan meat extract, which is prepared through the following steps:

[0053] Remove the core of longan pulp to obtain longan meat, weigh 500g of longan meat and add it to a masher, add 1L of distilled water for beating, import the slurry into a 5L three-necked bottle, add 2L of 95% ethanol solution, and heat under mechanical stirring Extract at 80° C. for 2 hours, cool to room temperature, and filter to obtain longan meat extract mother liquor 1 and longan meat filter residue. Add 2L of 40% ethanol aqueous solution to the longan meat filter residue, heat to 80° C. for extraction for 2 hours under mechanical stirring, cool to room temperature, and filter to obtain longan meat extract mother liquor 2. The longan meat extract mother liquor 1 and the longan meat extract mother liquor 2 were combined, and then concentrated under reduced pressure at 50° C. to obtain the longan meat extract.

Embodiment 2

[0055] The embodiment of the present invention provides a method for preparing spices using longan meat extract as a raw material using a microchannel reactor, and the preparation is carried out through the following steps:

[0056] Accurately weigh 150g of the longan meat extract prepared in Example 1 and 100g of glycine, add 650mL of propylene glycol and 350mL of water to mix while stirring, and dissolve the mixture under ultrasonic conditions at room temperature, cool to room temperature after the dissolution is complete, and use Grade NaOH was used to adjust the pH to 8 to obtain a reaction solution. Insert the suction pipe of the microchannel reactor into the prepared reaction solution, adjust the pressure of the microchannel reactor to 4bar, adjust the temperature of the microchannel reactor to 150°C, and wait until the temperature of the microchannel reactor reaches the set temperature , the flow velocity of adjusting reaction solution is 6.38mL / min, and reaction soluti...

Embodiment 3

[0063] The embodiment of the present invention provides a method for preparing spices using longan meat extract as a raw material using a microchannel reactor, and the preparation is carried out through the following steps:

[0064] Accurately weigh the longan meat extract prepared in Example 1 of 150g, the glycine of 50g and the threonine of 50g, add 650mL propylene glycol and the water mixing of 350mL while stirring, the mixture dissolves under ultrasonic conditions at room temperature, and cool down after dissolving completely to room temperature, and adjust the pH to 8 with food-grade NaOH to obtain a reaction solution. The pipette of the microchannel reactor was inserted into the prepared reaction solution, and the reaction solution was subjected to Maillard reaction according to the reaction system of using the microchannel reactor to prepare perfume in Example 2. Adjust the pressure of the microchannel reactor to 4bar, and adjust the temperature of the microchannel reac...

Abstract

The invention belongs to the technical field of cigarettes, and particularly relates to a method for preparing flavor by taking longan pulp extract as a raw material and adopting a micro-channel reactor and application of the method. The method for preparing the flavor by taking the longan pulp extract as the raw material and adopting the micro-channel reactor comprises the following steps: 1, mixing the longan pulp extract, amino acid, propylene glycol and water to obtain a mixture; and 2, pumping the mixture into a micro-channel reactor, and carrying out a Maillard reaction for 10 min at a temperature of 150-160 DEG C to obtain the flavor. The method for preparing the flavor by adopting the micro-channel reactor provided by the invention is used for overcoming the technical defects of time consumption, labor consumption and low yield in preparation of the tobacco flavor in the prior art.

Description

technical field [0001] The invention belongs to the technical field of cigarettes, and in particular relates to a method for preparing spices by using longan meat extract as a raw material and using a microchannel reactor and its application. Background technique [0002] my country is the largest country in the production and consumption of tobacco products in the world. In recent years, with the continuous deepening of consumers' health concept, the national bureau and cigarette industry enterprises have higher and higher requirements for reducing tar and harm, and tobacco products have further developed. However, as the work of reducing tar and harm continues to advance, consumers report that some cigarette products currently on the market have the shortcomings of insufficient satisfaction and insufficient smoke flavor. [0003] Tobacco flavoring is an indispensable additive added to cigarettes during the production process of cigarettes. It plays an extremely important ro...
