Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. The examples do not specify particular techniques or conditions, and are performed according to the techniques or conditions described in the literature in the art or according to the product specifications. The reagents or instruments used are not indicated by the manufacturer, and are all conventional products available by purchase.
Example 1: preparation of gas-containing coffee particles
The preparation of the airborne coffee particles of this example uses the apparatus shown in figure 3, with the following steps:
firstly, putting original coffee particles into a pressurizing container 1, and pressurizing to 1.5MPa at normal temperature; the original coffee particles are shown in fig. 1;
secondly, heating the pressurized container to 140 ℃ and keeping the temperature for one hour;
thirdly, cooling the pressurized container obtained in the second step to 20 ℃ under the pressure;
fourthly, slowly releasing the pressure of the pressurized container in the third step, and taking out coffee particles;
fifthly, screening the coffee particles obtained in the step (iv) according to the requirement to obtain the coffee gas-containing particles, as shown in figure 2. The obtained gas-containing coffee granules have a bulk density of 0.10g/cm3And contained 0.15ml/g of closed pores. The particles can produce a foam volume of 10cm3/g。
The principle and the steps for testing the bulk density and the leak tightness of the pores are the prior art and are as follows:
the weight and volume of the particles were measured by helium pycnometer (AccuPyc 1330Micromeritics), and the bulk density (g/cm) was obtained by dividing the weight by the volume3). The particle volume includes any air-tight void volume present in the particles, not including the interstitial spaces between particlesThe volume and any void volume present in the particles that is open to the atmosphere. The volume of the closed pores in the particles is obtained by measuring the skeleton density of the particles after removing all internal gaps of the particles or opening the particles to the atmosphere, wherein the skeleton density is also the real density of the single solid density of the particles, and is called the real density g/cm for short3. Pore volume of pore3The/g) is determined by subtracting the reciprocal true density from the reciprocal skeleton density. The closed pore volume can also be characterized by the volume percentage of closed pores contained in the particles.
Corrected according to the room temperature and the pressure, the gas amount released by the gas-containing granules of the coffee is 10cm per gram of the granules3Left and right.
Example 2: preparation of fruit essence containing qi granule
The preparation of the fruit juice gas-containing particles of the invention also uses the device as shown in figure 3, and comprises the following steps:
putting original fruit and pearl particles into a pressurizing container 1, and pressurizing to 2MPa at normal temperature;
secondly, heating the pressurized container to 120 ℃ and keeping the temperature for one hour;
thirdly, cooling the pressurized container obtained in the second step to 20 ℃ under the pressure;
fourthly, slowly releasing the pressure of the pressurized container in the third step, and taking out the fruit and pearl particles;
fifthly, screening the particles of the fruit juice obtained in the step (iv) according to the requirement to obtain the particles of the fruit juice containing gas. The obtained fruit juice gas-containing granule has a bulk density of 0.11g/cm3And contains 0.12ml/g of closed pores.
Corrected according to the room temperature and the pressure, the gas quantity released by the fruit juice gas-containing particles is 8cm per gram of the particles3Left and right.
Example 3: preparation of tea extract gas-containing granules

putting original tea extract particles into a pressurizing container 1, and pressurizing to 3MPa at normal temperature;
secondly, heating the pressurized container to 120 ℃ and keeping the temperature for one hour;
thirdly, cooling the pressurized container obtained in the second step to 20 ℃ under the pressure;
fourthly, slowly releasing the pressure of the pressurized container in the third step, and taking out the extract particles of the tea extract;
fifthly, screening the tea extract particles obtained in the step IV to obtain the gas-containing tea extract particles. The volume density of the gas-containing particles of the tea extract obtained by the test is 0.15g/cm3Which contains 0.09ml/g of closed pores.
Correcting according to room temperature and pressure to obtain extract containing tea extract with gas amount of 5 cm/g granule3Left and right.
Example 4: preparation of cigarette filter stick containing coffee gas particles and smoking evaluation result of cigarette
Weighing 20g of gas-containing particles of 40-60 meshes of coffee obtained in example 1;
secondly, adding the air-containing coffee particles dried in the step I into an acetate fiber tow, and uniformly adding the air-containing coffee particles into a cigarette filter stick according to the addition amount of 0.4mg/mm acetate fibers to prepare a particle filter stick. The granular filter stick and a filter stick with a built-in sealing water-containing firmware are compounded into a binary composite filter stick according to the thickness of 15mm +15 mm.
