Embodiment 1

[0052] The embodiment of the present invention provides a method for preparing raisin extract, which is prepared through the following steps:

[0053] Weigh 500g of raisins and add them 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, heat to 80°C under mechanical stirring conditions, extract for 2 hours, and cool to room temperature , and filtered to obtain raisin extract mother liquor 1 and raisin filter residue. Add 2L of 40% ethanol aqueous solution to the filtered fig residue, heat to 80° C. for extraction for 2 hours under mechanical stirring, cool to room temperature, and filter to obtain raisin extract mother liquor 2. Raisin extract mother liquor 1 and raisin extract mother liquor 2 were combined, and then concentrated under reduced pressure at 50° C. to obtain raisin extract.

Embodiment 2

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

[0056] Accurately weigh 150g of the raisin 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. 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 160°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 solution residence time is 10min, collects perfume (Maillard reaction product) at the outlet of microchannel reactor....

Embodiment 3

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

[0064] Accurately weigh 150g of the raisin extract prepared in Example 1, 50g of glycine and 50g of threonine, add 650mL of propylene glycol and 350mL of water to mix while stirring, and dissolve the mixture under ultrasonic conditions at room temperature. After the dissolution is complete, cool to room temperature and use Food grade NaOH was used to adjust the pH to 8 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 reactor to 1...

Abstract

The invention belongs to the technical field of cigarettes, and particularly relates to a method for preparing flavor by taking raisin extract as a raw material and adopting a micro-channel reactor and application of the flavor. The invention provides a method for preparing flavor by using vinasse extract as a raw material and adopting a micro-channel reactor, which comprises the following steps:step 1, mixing raisin 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 atemperature 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 oftime 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 using a microchannel reactor using raisin extract as a raw material and an application thereof. 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 role in...
