Problems solved by technology

However, in the process of supercritical CO2 fluid extraction, extraction pressure and temperature, separation pressure and temperature, fluid flow and extraction time, type and amount of entrainer are important factors that affect the extraction rate and biological activity of active ingredients. Propolis extract The extraction rate decreases with the increase of operating temperature; it increases continuously with the increase of pressure and carbon dioxide flow rate, but shows a downward trend at high pressure and high flow rate

Embodiment 1

[0035] The preparation of embodiment 1 propolis net glue

[0036] A preparation process of propolis net glue, comprising the following steps:

[0037] 1) Pretreatment: collect 165kg of Brazilian green propolis glue for precooling treatment, the precooling temperature is -10°C, the precooling time is 12 hours, and then crushed to obtain propolis particles;

[0038] 2) Mixing: mixing the pretreated propolis particles and rice husks in a weight ratio of 1:4 to obtain a mixture;

[0039] 3) Non-critical fluid extraction: add n-butane to the mixture to extract in an extraction tank, the extraction pressure is 6MPa, the temperature is 40°C, and the stirring speed is 30rpm; stand still for 60min to obtain n-butane extract;

[0040] 4) Solid-liquid separation: the n-butane extract is transferred to the evaporation tank for evaporation, and the propolis net glue and the rice husk with the propolis net glue are left in the extraction tank;

[0041] 5) Screening: Sieve the net propolis...

Abstract

The invention discloses pure propolis and a preparing process thereof, and further discloses propolis freeze-dried powder and a preparing process thereof. The preparing processes are simple, steps are simple, operation time is short, and requirements for equipment are low. By comparing the content of non-liposoluble propolis extract obtained through non-critical n-butane extraction with crude propolis, it is found that the yield of pure propolis is 30-35%, total flavonoid content is 22-25%, the yield of propolis freeze-dried powder is 22.5-23.2%, and total flavonoid content is 20-25%.

Description

technical field [0001] The invention belongs to the field of traditional Chinese medicine health care, and in particular relates to clean propolis glue, freeze-dried powder of clean propolis glue and a preparation process and application thereof. Background technique [0002] Propolis is a resinous substance secreted by worker bees from poplars, willows and other plants and the secretions of their own digestive glands and wax glands (such as beeswax and various digestive enzymes). A viscous natural mixture formed after mixing. Propolis is an effective substance used by bees to maintain the health of the whole group. A colony of 50,000 to 60,000 bees can only produce 100 to 150g of propolis a year, so it is known as "purple gold". Propolis is mostly blue-brown, yellow-brown or dark brown, and is a solid sticky substance. Bitter, irritating, resinous aroma when burned, viscous and plastic at 35-45°C, soluble in viscous fluid at 65°C, dissolved at 100°C, hard and brittle at 1...
