Problems solved by technology

Ethanol extraction is still the preferred industrial extraction method for most enterprises due to its high dissolution rate of flavonoids, simple process and low equipment investment. However, the existing technology has unreasonable extraction process, low flavonoid content in High lead content, deep black extract; incomplete extraction leads to low extraction efficiency and other technical bottlenecks

Embodiment Construction

[0014] The present invention will be further described below in conjunction with specific embodiments.

[0015] Freeze the wool glue at -4~-8℃ for 24 hours; the frozen wool glue is crushed with 10-20% crushing medium, because the physical properties of propolis determine that it is in a semi-plastic state at room temperature, very Difficult to break, in order to meet the requirements of crushing particle size, supplemented by filling medium, it is not easy to bond. The pulverized wool rubber particles immediately enter the vibrating sieve; after the sieved particle fineness is 40-60 mesh wool rubber particles, mix with 82% edible ethanol according to the batching ratio of 4-6:1 (solid-liquid ratio), Extract at 25-30°C for 48 hours. During the extraction process, the temperature should be kept at 25-30°C. If the temperature is too high, it will cause a large amount of beeswax to melt and make filtration difficult; if the temperature is too low, the solubility of propolis will d...

Abstract

The invention relates to a method for extracting propolis, and belongs to the technical field of extraction and separation of the propolis. According to the method for extracting the propolis, ethanol at different concentrations is used for extracting the propolis, a process is simple, process parameter ranges are accurate, the flavonoid content of the propolis is increased, lead content of the propolis is lowered, and the quality of the propolis is improved. The method is improved in a way that an ultrasonic cavitation technology and a technology for extracting the propolis by using the ethanol at different concentrations are combined, and by a thermal effect, mechanical action and a cavitation effect generated by ultrasonic waves, the ethanol which serves as an extraction solvent easilypermeates into a solute, so that the extraction time is shortened, the flavonoid content of propolis extract is increased, and the extraction efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of extraction and separation of propolis, in particular to a method for extracting propolis with ethanol. Background technique [0002] Propolis is the resin and juice collected by bees from the bark or shoots of collagenous plants such as poplar, birch, willow and coniferous trees, and mixed with the secretion of the bee's own throat glands. Flavonoids are the main functional components of propolis, and propolis flavonoids have a wide range of biological activities, such as anti-oxidation, anti-tumor, anti-inflammatory and immune cell regulation effects. [0003] The extraction and production methods of modern propolis industrialization are mainly ethanol extraction and supercritical CO2 extraction. Most of the components extracted by these two extraction methods are flavonoids. Ethanol extraction is still the preferred industrial extraction method for most enterprises due to its high dissolution rate of f...
