Preparation method of green prunusmume fruit extract

Abstract

The invention discloses a preparation method of a green prunusmume fruit extract. The preparation method comprises the steps of removing kernels of green prunusmume fruits, performing breaking to obtain green prunusmume fruit puree, mixing the green prunusmume fruit puree with saccharomyces rouxii, lactobacillus acidophilus, bacillus natto and distiller's yeast GGSF16 in the weight ratio of (100-120) to (1-3) to (1-5) to (2-3) to (2-5 ), performing sealing fermentation under the condition of room temperature for 2-3 days, and then performing sterilization with vapour of 100-120 DEG C to obtaina green prunusmume fruit fermented product; mixing the green prunusmume fruit fermented product with edible alcohol and a catalyst, performing a catalytic reaction under the stirring condition of 15-40 DEG C for 1-24h, and further obtaining a green prunusmume fruit extracting solution, wherein the catalyst comprises an acid catalyst and a salt catalyst; and adjusting the green prunusmume fruit extracting solution to be neutral with baking soda or edible sodium carbonate, performing drying treatment with supercritical carbon dioxide, and further obtaining the powdery green prunusmume fruit extract. According to the preparation method of the green prunusmume fruit extract provided by the invention, effective components in the green prunusmume fruit raw materials can be effectively separated, and the content of furfural and the content of ester in the green prunusmume fruit extract can be increased.

Description

technical field [0001] The invention particularly relates to a preparation method of green plum extract, which belongs to the technical field of plant active ingredients. Background technique [0002] Greengage is the near-ripe fruit extract of the Rosaceae arbor plant PrunusMume (Sieb) siebetZuCe. Green plum is also known as plum, black plum and white plum. It has been cultivated in China for more than two thousand years. Green plums have been used for sterilization, treatment of hepatitis and extraction of traditional Chinese medicine dipterocarp for a long time in Hainan. Foreign studies on the chemical constituents of Prunus genus plants have mainly obtained white Chemicalbook reveratrol oligomers and triterpenoids. Resveratrol and its oligomers have attracted attention due to their biological activities such as anti-human immunodeficiency virus (HIV), anti-tumor, anti-oxidation, antibacterial and anti-inflammatory. Domestic studies have shown that green plum fruit i...

Problems solved by technology

[0003] The main components of green plum extract include ketones, acids, acid anhydrides, aldehydes and esters, among which aldehydes can be used as raw materials for organic synthesis, and also for synthetic resins, varnishes, pesticides, medicines, rubbers and paints; CN106619335A discloses a preparation method of green plum extract, which mainly adopts microwave extraction, activated carbon decolorization, and reduced-pressure concentration to obtain green plum extract. In this method, it is difficult to extract the active ingredients of green plum, the extraction efficiency is low, and the profit Poor, no obvious advantages in industrial production
