Problems solved by technology

[0004] The existing propolis wax removal technology has the disadvantages of high cost, cumbersome process, high temperature requirements, low wax removal efficiency, and long consumption time; although water extraction wax removal rate is not low, there will be some phenolic acids in propolis The active ingredient is dissolved in water and lost, and it needs to be in a high temperature environment of 70°C, which will affect the content of flavonoids, the main active substance in propolis; supercritical CO 2 Wax removal requires a high-temperature heating environment with high cost and cumbersome process. The same high-temperature and high-pressure environment, generally with a pressure of 30MPa and a temperature of 60°C, will affect the content of flavonoids, the main active substance in propolis, and the extraction rate of flavonoids in propolis. ;Alcohol extraction and cold immersion dewaxing do not require high-pressure and high-temperature heating treatment, but the dewaxing efficiency is very low, which cannot meet the requirements of dewaxing

Abstract

The invention relates to the technical field of food processing, in particular to a propolis wax removal method. The c comprises the following steps that 1, raw material processing is performed: impurity removal and smashing are conducted on natural propolis; 2, beewax is extracted by using petroleum ether: the beewax is evenly mixed in the petroleum ether, suction filtration and two times of extraction are performed, two times of extracts naturally volatilize to obtain beewax extracting amount; 3, propolis is extracted by using ethanol: two times of insoluble substances extracted for two times in the step 2 act in the ethanol to generate an ethanol extracting solution, then rotary drying is performed in a rotary evaporator to obtain the propolis weight. The propolis wax removal method is performed under the normal pressure and normal temperature of 25 DEG C, does not need a high-temperature and high-pressure environment and does not influence the flavonoid substance content in the propolis. In addition, the method is simple in operation and high in propolis wax removal rate, the extracting rate of the flavonoid substance in the propolis is improved, and the propolis has the positive significance on wax removal treatment.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a method for removing wax from propolis. Background technique [0002] Propolis is an aromatic solid made of bees collecting resin secreted by plant leaf buds or bark cracks and mixed with mandibular gland secretions and beeswax. It is mainly composed of beeswax, resin and volatile substances; in industrial production, it will It affects the extraction rate of flavonoids in propolis, and beeswax contains heavy metals, and long-term consumption is prone to heavy metal poisoning. [0003] Existing propolis wax removal technologies include water extraction, supercritical CO 2 Wax removal, wax removal by alcohol extraction and cold immersion, etc.; wax removal by water extraction is achieved by controlling the material ratio of water and propolis and the temperature of water; supercritical CO 2 Wax removal is under a certain pressure, at a certain flow rate of CO 2 Air flo...
