Embodiment 1
[0043] Example 1 Preparation of propolis net glue
[0044] A preparation process of propolis net glue includes the following steps:
[0045] 1) Pretreatment: Collect 165kg of Brazilian green propolis gel and perform pre-cooling treatment, the pre-cooling temperature is -10 ℃, the pre-cooling time is 12 hours, and then pulverize to obtain propolis particles;
[0046] 2) Mixing: Mix the pretreated propolis particles and rice husk in a weight ratio of 1:4 to obtain a mixture;
[0047] 3) Non-critical fluid extraction: add n-butane to the mixture for extraction in the extraction tank, the extraction pressure is 6MPa, the temperature is 40°C, and the stirring speed is 30rpm; stand for 60min to obtain the n-butane extract;
[0048] 4) Solid-liquid separation: the n-butane extract is transferred to the evaporation tank for evaporation, and the propolis net glue and rice husk with propolis net glue are left in the extraction tank;
[0049] 5) Screening: Sieve the net propolis and the rice husk w...
Embodiment 4
[0062] Example 4 Preparation of freeze-dried propolis powder
[0063] 1) Soaking: The rice husk with propolis gel obtained in step 5) of Example 1 was added with 95% food grade ethanol at a solid-to-liquid ratio of 1:5 while stirring, soaking for 12 hours at a stirring speed of 40 rpm to obtain a solid Liquid mixture
[0064] 2) Solid-liquid separation: The solid-liquid mixture is sieved with an 80-mesh sieve, the rice husks are removed and collected, and the supernatant is left in the extraction tank and allowed to stand for 4-6 hours. The supernatant is heated to obtain a semi-fluid leaching 75kg of paste and recovery of food grade ethanol at the same time; heating temperature is 50℃; pressure in extraction tank is -0.1MPa;
[0065] 3) Freeze-drying: vacuum freeze-drying the semi-fluid extract to obtain freeze-dried propolis powder particles, which are divided into three stages: pre-cooling treatment, freezing treatment, and heating treatment; the pre-cooling temperature is -18°C,...
Embodiment 5
[0067] Example 5 Preparation of propolis lyophilized powder
[0068] 1) Soaking: The rice husk with propolis gel obtained in step 5) of Example 2 was added with 95% food grade ethanol at a solid-to-liquid ratio of 1:8 while stirring, soaking for 16 hours, and stirring at 30 rpm to obtain a solid Liquid mixture
[0069] 2) Solid-liquid separation: The solid-liquid mixture is sieved with an 80-mesh sieve, the rice husks are removed and collected, and the supernatant is left in the extraction tank and allowed to stand for 4-6 hours. The supernatant is heated to obtain a semi-fluid leaching 69kg of paste and recovery of edible ethanol at the same time; heating temperature is 55℃; pressure in extraction tank is -0.9MPa.
[0070] 3) Freeze-drying: vacuum freeze-drying the semi-fluid extract to obtain freeze-dried propolis powder particles, which are divided into three stages: pre-cooling treatment, freezing treatment, and heating treatment; the pre-cooling temperature is -20°C, overnight ...
