Method for Areca catechu L. preservation by Chinese herbal medicine extracts

Abstract

The invention discloses a method for Areca catechu L. preservation by Chinese herbal medicine extracts. In the method, water solubles of rhizoma zingiberis recens and bulbus allii sativa and extractsof Hainan tropical plants Hernandia sonora L., Canthium horridum Bl., Hainania trichosperma Merr., Vatica mangachapoi Blanco and the like are used for carrying out preservation on Areca catechu L. fresh fruits, the quality, the pH value, the VC content and the total sugar content change of the Vatica mangachapoi Blanco are reduced, and a Vatica mangachapoi Blanco preservation effect is improved. Under the same storage time, a healthy fruit rate of the Areca catechu L. which is coated by various extraction liquids and is sealed and stored is higher than the Areca catechu L. which is not subjected to dipping processing by the extracts, microbial activities on the surface of fruits can be inhibited, the activity of enzymes in the fruits can be reduced, physiological activity intensity is lowered, respiration intensity is regulated and controlled, internal moisture can be prevented from being lost too fast, speed for oxygen to permeate into the fruits can be controlled, and the nutrient loss of the fruits is avoided. Natural extracts are used for fruit and vegetable preservation, and therefore, safety is much higher than the safety of a traditional chemical preservative. In addition, alow-concentration solution is adopted to carry out dipping and film formation, cost is low, and operation is easy.

Description

technical field [0001] The invention belongs to the technical field of fresh-keeping of fruits and vegetables, and in particular relates to a method for keeping fresh of betel nut by Chinese herbal medicine extract.

In particular, it should be pointed out that it is difficult to remove harmful substances such as soot and benzopyrene in smoked and dried betel nuts; fresh betel nuts can avoid this problem. Due to the high cost of traditional cold storage, the price of fresh betel nuts varies greatly between the harvest season and the non-harvest season. The former is 4-5 yuan / kg, and the la...
