Problems solved by technology

However, the current alcohol extraction process lacks an extraction step for propolis water-soluble substances.
[0008] There are many deleading methods of existing propolis purification technology, but there are certain problems: Chinese patent application number 00105486.4 discloses a process for propolis extraction and deleading. The cost is very high; the effects of sedimentation filtration and chemical methods for removing lead are not very satisfactory; Chinese patent application number 200310122475.X discloses a method for removing lead in propolis by adsorption and ion exchange, which uses medical stone adsorption Lead removal, Chinese Patent Application No. 03131752.9 discloses a method for supercritical fluid hybrid extraction of propolis, which uses carbon dioxide supercritical extraction to remove lead. Although their lead removal effects are good, they all have high requirements for equipment and excessive cost. high problem

Embodiment 1

[0038] (1) Low-temperature crushing and sieving

[0039] Put 100kg of wool gum purchased from a beekeeping cooperative into a low-temperature pulverizer, pulverize at -5°C to 10-mesh particles, and pass through a 5-mesh stainless steel screen to obtain hair glue particles.

[0040] (2) Loop extraction

[0041] At 20°C, add 700kg of 90% (v / v) edible alcohol to the above rubber particles as the first extraction solution, mix and stir in the reaction kettle for 24 hours, let stand for 6 hours, and take the supernatant as one time The extract is filtered through a 100-mesh filter and pumped into a mixing tank for use.

[0042] Put 700kg of 95% (v / v) edible alcohol into the reaction kettle containing the remaining materials, mechanically mix and stir in the reaction kettle for 24 hours at 20°C, and let it stand for 6 hours to take the supernatant as the second extraction , by the above-mentioned same method, in the second batch of pulverized 100kg wool gum particles, add the extr...

Embodiment 2

[0060] (1) Low-temperature crushing and sieving

[0061] Put 100kg of wool gum purchased from a beekeeping cooperative into a low-temperature pulverizer, pulverize at -10°C to 30-mesh particles, and pass through a 20-mesh stainless steel screen to obtain hair glue particles.

Abstract

The invention relates to an efficient propolis extraction and lead removal method. The method introduces circular extraction, water-soluble substance extraction, physical adsorption lead removal and concentration drying steps, so the propolis total substance extraction rate is improved, and the extraction rate and the production efficiency are improved. Especially the above physical lead removal process reduces the lead content, and the method has the advantages of simplicity, high efficiency, safety, reliability, propolis quality improvement and propolis use safety improvement.

Description

technical field [0001] The invention relates to the technical field of propolis extraction, in particular to a method for extracting propolis with edible alcohol and water. Background technique [0002] Propolis is a collection of animal and plant essences, and contains more than 100 kinds of flavonoids that can improve human health. Propolis contains more than 300 chemical components, including aromatics and flavonoids, organic acids, terpenes, vitamins, enzymes, etc. (Castrosl, 2001), so that it has many proven or being proven physiological functions . Propolis has antibacterial and antiseptic effects (Liang Yuqiang et al., 1999; Marko Xiang, 1990), antiviral effect (Amoros et al., 1992), anticancer effect (Sakamoto, 1994; Banskota, 1998), liver protection effect (Remirez, 1997; Ricardo, 1994), anti-fatigue effect (Wu Cuiwen et al., 1997); antioxidant, antibacterial, anti-inflammatory, antiviral, liver protection and anticancer effects (Alencar, S.M et al., 2007). With ...
