Embodiment 1

[0023] (1) Take corn silk and grind it through a 80-mesh sieve, mix corn silk with water at a mass ratio of 1:15, then control the ultrasonic frequency to 50KHz for 30 minutes, and then use NaAc-HAc solution to sonicate the resulting mixture The pH of the mixture was adjusted to 5, and then the mixture was allowed to stand for 8 hours to pass through a 0.8 μm filter membrane to obtain a filtrate, and the obtained filtrate was concentrated to half of the total mass of corn silk and water at the beginning to obtain sample No. 1 of corn silk extract;

[0024] (2) Grind corn silk with the same quality as in step (1) and pass through an 80-mesh sieve, mix the corn silk with an ethanol solution with a volume fraction of 70% in a mass ratio of 1:50, and then mix the resulting mixture Adjust the microwave power to 200W at 70°C for microwave extraction for 9 minutes, and then pass the obtained extract through a 0.8 μm filter membrane to obtain the filtrate obtained as the No. 2 sample o...

Embodiment 2

[0027] (1) Take corn silk and grind it through a 80-mesh sieve, mix corn silk with water at a mass ratio of 1:17, then control the ultrasonic frequency to 35KHz for ultrasonic treatment for 20 minutes, and then use NaAc-HAc solution to sonicate the resulting mixture The pH of the mixture was adjusted to 5, and then the mixture was allowed to stand for 8 hours to pass through a 0.8 μm filter membrane to obtain a filtrate, and the obtained filtrate was concentrated to half of the total mass of corn silk and water at the beginning to obtain sample No. 1 of corn silk extract;

[0028] (2) Grind corn silk with the same quality as in step (1) and pass through an 80-mesh sieve, mix the corn silk with an ethanol solution with a volume fraction of 60% in a mass ratio of 1:40, and then mix the resulting mixture Adjust the microwave power to 350W at 60°C to carry out microwave extraction for 8 minutes, and then pass the obtained extract through a 0.8 μm filter membrane to obtain the filtr...

Embodiment 3

[0031] (1) Take corn silk and grind it through a 80-mesh sieve, mix corn silk with water at a mass ratio of 1:20, then control the ultrasonic frequency to 25KHz for ultrasonic treatment for 15 minutes, and then use NaAc-HAc solution to sonicate the resulting mixture The pH of the mixture was adjusted to 6, and then the mixture was left to stand for 10 hours and then passed through a 0.8 μm filter membrane to obtain a filtrate, and the resulting filtrate was concentrated to half the total mass of the initial corn silk and water to obtain the corn silk extract No. 1 sample;

[0032] (2) Grind corn silk with the same quality as in step (1) and pass through an 80-mesh sieve, mix the corn silk with an ethanol solution with a volume fraction of 50% in a mass ratio of 1:30, and then mix the resulting mixture Adjust the microwave power at 50°C to 500W for microwave extraction for 6 minutes, and then pass the obtained extract through a 0.8 μm filter membrane to obtain the filtrate obtai...

Abstract

The invention discloses a preparation method of a corn stigma extract for cigarettes. The preparation method comprises the following steps of: (1) mixing corn stigma with water at a mass ratio of 1:(15-20), performing ultrasonic treatment on the mixture for 15-30 minutes and then regulating the pH of the mixture to the range from 5 to 6, filtering the mixture after standing for 6-10 hours, and concentrating the filtrate, thereby obtaining a corn extract sample I; (2) mixing the corn stigma with an ethanol solution with volume fraction of 50%-70% at a mass ratio of 1:(30-50), extracting the mixture for 6-9 minutes by microwaves at a temperature of 50-70 DEG C, and then filtering the mixture, thereby obtaining a corn extract sample II; (3) pouring the sample II into the sample I at a mass ratio of the sample I to the sample II of (2-3):1, stirring while pouring for 15-30 minutes, and then standing for 6-10 hours; then taking the liquid supernatant for filtering, and then concentrating the filtrate to one third of the original mixed liquid. The corn stigma extract is added to cigarettes, and has the effects of softening smoke gas, increasing the fragrance and the sweet taste, and covering offensive odor.

Description

technical field [0001] The invention relates to a method for preparing tobacco flavor, in particular to a method for preparing tobacco corn silk extract. Background technique [0002] Because smoking is harmful to health, smoking has become an increasingly serious social problem. In order to ensure safe smoking, general enterprises reduce the tar and nicotine content in the smoke, and at the same time add tobacco flavoring materials to ensure the aroma and taste of tobacco products. However, the traditional method of adding spices to cigarettes, that is, mixing and blending natural extract monomers and synthetic monomers, has disadvantages such as monotonous aroma, not plump, uncoordinated with tobacco, and ineffective improvement of cigarette smoking quality. [0003] Corn silk is also called corn beard, corn silk, corn stamen, and cob hair. It contains chemical components such as flavonoids, polysaccharides, organic acids, amino acids, and sterols. Modern pharmacological ...
