Abstract

The invention relates to a processing method of a green betel nut dry fruit with low arecoline content, comprising the following steps: 1. selecting betel nuts without insects and diseases, cleaning and slicing the betel nuts and removing kernels for later use; 2. preparing mixed green-protecting liquid, which contains zinc acetate with the concentration of 0.02-0.1 percent, citric acid with the concentration of 0.1-0.3 percent and potassium sorbate with the concentration of 0.02-0.1 percent; and soaking the betel nuts obtained in the step 1 in the mixed green-protecting liquid for 12-24 hours; 3. drying the soaked betel nuts in a blowing dry box with the temperature of 45-65 DEG C, and then packaging finished products in vacuum. The processing method not only effectively protects the green color of the betel nuts but also reduces the arecoline content and has simple steps and low operation cost; in addition, the prepared edible betel nuts have higher edible safety.

Description

technical field [0001] The invention relates to a processing method of dried betel nut. Background technique [0002] Areca nuts are abundant in Hainan Province of my country.
