Abstract

The invention provides a method for extracting an areca nut extract from fresh areca nuts. The method comprises the steps of carrying out pretreatment, performing steam explosion, extracting by usinga strong electric field, carrying out evaporation and concentration, and carrying out freeze-drying to obtain the areca nut extract. The areca nut extract prepared by the method is rich in areca nut polyphenol, thus being widely applied to antioxidant and antibacterial products; furthermore, the content of MDA in the areca nut extract prepared by the method is significantly reduced, the activity of superoxide dismutase (SOD) is improved, and the content of NO is remarkably increased; therefore, the areca nut extract can be applied to preparation of anti-altitude products.

Description

technical field [0001] The invention relates to the technical field of betel nut processing, in particular to a method for preparing areca nut extract from fresh betel nut fruit. Background technique [0002] Betel nuts are originally produced in Malaysia, and China is mainly distributed in tropical areas such as Yunnan, Hainan and Taiwan. Widely cultivated in tropical Asia. Betel nut fresh fruit is the fruit of betel nut, which is rich in various active ingredients. The extraction rate of areca nut polyphenols by existing extraction methods is low, and the application value has not been fully utilized. Therefore be badly in need of a kind of method for preparing betel nut extract from betel nut fresh fruit, solve above-mentioned technical problem. Contents of the invention [0003] In view of this, the present invention proposes a method for preparing areca nut extract from fresh betel nut fruit to solve the above technical problems. [0004] Technical scheme of the pr...
