Problems solved by technology

[0003] However, lotus mist is not resistant to storage. Generally, it can only be stored for one week at room temperature. During the peak harvest season, it is easy to backlog and cause economic losses.
At present, there are no deep-processed lotus mist products on the market, and the extraction rate of polysaccharides and polypeptides in lotus mist is low

Abstract

The invention relates to the field of food processing, in particular to a preparation method of a syzygium samarangense extract. The preparation method comprises steps as follows: freezing syzygium samarangense, conducting pulping to obtain syzygium samarangense pulp, performing extraction with ethanol as a solvent, allowing the obtained material to pass through non-polar macroporous adsorption resin, collecting ethanol eluates at different concentrations, and performing concentration and drying to obtain the syzygium samarangense extract. By means of the preparation method of the syzygium samarangense extract, the content of nutritional ingredients, such as polysaccharides and polypeptides, in the syzygium samarangense extract is increased.

Description
