[0034] Example 1. Preparation of garlic polysaccharide microcapsules
[0035] Exploratory experiment of the concentration of polysaccharide in the feed liquid on the preparation process of garlic polysaccharide microcapsules:
[0036] a: Choose clean and peeled 150g fresh garlic, grind it with a chopper, add different volumes of distilled water (the mass ratio of garlic to water is 10%-50%) to prepare polysaccharide extract, and place it in a 80℃ water bath Extract at a constant temperature for 2.5 hours, filter out the filter residue with 300 mesh nylon cloth, and obtain a crude extract by suction filtration;
[0037] b: The extract is centrifuged at 8000 rpm for 10 minutes, the precipitate is discarded, and the supernatant is vacuum concentrated at 50°C, so that the concentration of the concentrated polysaccharide extract reaches 15% to 75% (calculated as the concentration of the feed solution , As shown in Table 1); and collect the concentrate;
[0038] c: When the wall material i...

[0046] Example 2. Preparation of garlic polysaccharide microcapsules
[0047] The research experiment of adding amount of wall material to the process of microencapsulation:
[0048] a: Choose clean and peeled 150g fresh garlic, mince it with a chopper, add 1.5L distilled water to prepare polysaccharide extract, extract 2.5h at a constant temperature in a water bath at 80℃, filter out the filter residue with 300 mesh nylon cloth, and filter with suction To obtain a crude extract;
[0049] b: The extract was centrifuged at 8000 rpm for 10 minutes, the precipitate was first discarded, and the supernatant was vacuum concentrated at 50°C to make the concentration of the concentrated polysaccharide extract reach 30%; and the concentrate was collected;
[0050] c: When the wall material is mixed with the concentrated solution, use shear mixing to ensure uniform mixing. The shearing conditions include: the shear speed is 8000r / min, and the time is controlled within 4min; the wall material ad...

[0058] Example 3. Preparation of garlic polysaccharide microcapsules
[0059] Experiment on the influence of inlet air temperature on the powder output of microcapsules:
[0060] a: Choose clean and peeled 150g fresh garlic, mince it with a chopper, add 1.5L distilled water to prepare polysaccharide extract, extract 2.5h at a constant temperature in a water bath at 80℃, filter out the filter residue with 300 mesh nylon cloth, and filter with suction To obtain a crude extract;
[0061] b: The extract was centrifuged at 8000 rpm for 10 minutes, the precipitate was first discarded, and the supernatant was vacuum concentrated at 50°C to make the concentration of the concentrated polysaccharide extract reach 30%; and the concentrate was collected;
[0062] c: When the wall material is mixed with the concentrated solution, use shear mixing to ensure uniform mixing. The shearing conditions include: the shear speed is 8000r / min, the time is controlled within 4min; the wall material addition a...
