Problems solved by technology

[0003] In the prior art, the extraction of ergosterol is mostly an organic solvent extraction method. When extracting ergosterol, a large amount of irrelevant substances are also extracted, which not only consumes a large amount of organic solvents, but also because ergosterol finally plays a role in oral administration. Related to health effects, the extract obtained by organic solvent extraction is not well adaptable to the human intestinal tract. At the same time, because edible fungi are easy to accumulate heavy metals, the content of heavy metals in the extract obtained by organic solvent extraction may also exceed the standard

Abstract

The invention discloses a method for preparing hydrangea ergosterol by electric field-semi-bionic technology, comprising the following steps: (1) taking hydrangea fruit bodies, grinding and sieving to obtain hydrangea powder; (2) under external electric field conditions, using A strong alkali solution with a pH of 9‑10 is used as a raw material, and saponified at 90°C to obtain ergosterol; (3) electrolytically reducing the heavy metal ions desorbed from the denatured protein in the step (2); (4) taking the step (3) The mixed solution obtained in (3) is centrifuged to obtain the bottom sediment, the middle layer floc and the supernatant; (5) Take the middle layer floc, use ethanol aqueous solution as the extraction solution, adjust the pH to 3-4 with a weak acid, and put it in a water bath Extract and filter to obtain the filtrate; (6) combine the supernatant and filtrate, adjust the pH to neutral, and rotary evaporate to obtain the concentrated solution, vacuum freeze-dry the concentrated solution, and the obtained powder is the anti-oxidative hydrangea ergosterol, ergosterol High extraction rate, removal of heavy metals and hydrangea protein, stable properties, good absorption through the gastrointestinal tract.

Description

technical field [0001] The invention relates to the field of hydrangea, in particular to a method for preparing hydrangea ergosterol by an electric field-semi-bionic technology. Background technique [0002] Ergosterol, also known as ergosterol, is a characteristic alcohol contained in fungi. Hydrangea has a large and stable content in edible fungi. It is often used as the main raw material for vitamin D2 production, which can promote the body’s absorption of vitamin D2, phosphorus, etc. It is beneficial to the formation of bones and prevents rickets in children, osteoporosis and osteomalacia in adults. At the same time, ergosterol is an important part of microbial cell membranes, which is important for ensuring the integrity of cell membranes, the activity of membrane-bound enzymes, and the flow of membranes It plays an important role in sex, cell viability, and cell material transportation, but it is easily oxidized to yellow when exposed to sunlight and air, and its prope...
