Green vegetable leaf dehydration process

Abstract

Provided is a green vegetable leaf dehydration process. The dehydration process comprises the steps of 1 preparation, wherein green and superior pakchoi cabbage leaves are selected and then washed to be clean for use; 2 drying in the shade, wherein the prepared pakchoi cabbage leaves are dried in a natural shade place for 2 days to 6 days, and 70% of water is removed; 3 hot-water dehydration, wherein the pakchoi cabbage leaves are put into a boiling water pot, and dehydration is conduced for 4 min to 6 min in an opening state; 4 rib pulling, wherein fibers in the leaves are pulled out; 5 salting, wherein one jin of salt is added into every 100 jin of the pakchoi cabbage leaves, and mixing is conducted to be uniform; 6 secondary drying in the shade, wherein the mixture is dried in the natural shade place for one day to three days, and 90% of water is removed; 7 microwave dehydration, wherein the pakchoi cabbage leaves are subjected to dehydration treatment for 3 min to 5 min in a microwave environment; 8 vacuum subpackaging, wherein the pakchoi cabbage leaves are subpackaged with subpackaging bags, and totally closed vacuum sealing is conducted. According to the green vegetable leaves made through the method, the preservation time is longer, the original taste of pakchoi cabbages is not destroyed, and more chlorophyll integrity is kept.
