A kind of comprehensive extraction and utilization production process of propolis

Abstract

The invention discloses a comprehensive extraction and utilization production technology for propolis. The method comprises the following steps: 1) pretreatment; 2) mixing; 3) non critical fluid extraction; 4) removal of n-butane through ultimate vacuum; 5) addition of a weak solution for mixing; 6) removal of n-butane through ultimate vacuum; 7) de-waxing; and 8) solid-liquid separation. The invention employs an extraction technology by taking low-temperature non critical fluid n-butane as a solvent, Brazilian A-grade propolis is taken as a raw material, and the propolis particles can be prepared by steps of selection, refrigeration at the temperature of -10 DEG C, crushing, blending with rice husk, extraction by employing non-critical fluid, screening, freeze drying, crushing and package, and propolis premix liquid is prepared by the steps of desolvation through ultimate vacuum, addition of a diluents, de-waxing, filtering and package. propolis yield is 30-35%, the general flavone content is 22-25%, the general flavone content in propolis freeze-drying powder is 22-25%, and the lead content is 0.48-0.50 mg / kg.

Description

technical field [0001] The invention belongs to the technical field of health food production and processing, and in particular relates to a production process for comprehensive extraction and utilization of propolis. 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 15°C. Propolis is insoluble i...

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
