What is propolis?
Propolis is known as "purple gold. It is a gel-like solid substance
with aromatic door, which is a mixture of the tender shoots of the
honey plant and the resin collected on the trunk, mixed with its
own maxillary gland secretions and beeswax. Propolis has strong
bacteriostatic effect.
What the main functions and effects of propolis ?
1. Anti-inflammatory and sterilization, can eliminate some
microorganisms and play a role of sterilization and disinfection;
2. Because it is rich in anti-cancer substances, it can prevent the
occurrence of tumors;
3. Beauty, which can eliminate wrinkles and delay aging, is a good
beauty product for women.
4. For some people with constipation, it can be laxative.
Process of Propolis Extract
1. Pre select and grade raw materials to remove impurities.2. Put the pre selected raw materials into the refrigerator at - 18
℃for 48h.
3. Raw materials shall be crushed in crusher after freezing. It's
easy to break under - 5 ℃.
4. The crushed raw materials are put into the vibrating screen (14
mesh), and the particles larger than 14 mesh are returned to the
refrigerator.
5.Put the crushed and screened raw materials into the immersion
kettle with reflux condenser. Add 90% ethanol [propolis
(weight):ethanol (volume = 1:4)], stir for 6h at room temperature,
stand for 2h, discharge the supernatant, add 90% ethanol, repeat
the
above process for 3 times, and combine the solution. During the
impregnation, the temperature is about 25 ℃.
6. After immersion,the solution enters the cooling reaction kettle,
circulates in the adding sleeve for cooling, mechanically stirs and
cools to
below 5 ℃.
7. Filter the cooled solution with a filter. When the solution
temperature is less than 5 ℃, the beeswax can be separated out and
filtered out with the filter residue.
8. The filtrate enters the decompression evaporator and the water
bath is
heated. When the temperature is less than 50 ℃, the evaporation of
volatile oil and the thermal denaturation of effective components
can be reduced.
9. The evaporated ethanol vapor is recycled by the condenser and
injected into the solvent storage tank for recycling.
10. After the evaporated propolis is injected into the mold, it
becomes (pure propolis) commodity.
