| titleOfInvention | A kind of extraction method of pitaya peel anthocyanin |
| abstract | The invention discloses a method for extracting anthocyanins from pitaya peel. First, the raw materials are pulverized into 30-70 mesh fine powder; then, compound enzyme + 35% ethanol + water are used to extract three times, the extraction temperature is 30 DEG C, and the extraction time is 20 minutes respectively , 30min, 40min, vacuum recovery ethanol, the concentrate is added with water to precipitate and remove impurities; supercritical CO2 extraction and separation, the temperature is 37 ℃, the pressure is 25MPa; after refining and removing impurities Combined, the mass ratio is 1:4, the mass fraction of dextrin is 30%, the inclusion temperature is 20°C, and spray drying is carried out; the final inspection, packaging and storage are carried out. The method for extracting pitaya peel anthocyanins utilizes membrane separation technology, supercritical extraction separation technology, low temperature separation technology and hydroxypropyl-β cyclodextrin inclusion technology to obtain pitaya peel extract powder with good stability and high purity , Not easy to change color, good water solubility, and good stability. |
