Abstract

The invention relates to the technical field of vegetable processing, in particular to a preparation method of green food quick-frozen green sword beans. The method comprises the following steps: (1) raw material acceptance and picking: detecting green sword beans one week before picking, and picking the green sword beans after the green sword beans are detected to be qualified; (2) head removing and tail removing: removing the heads and tails of the green sword beans; and (3) processing treatment: sequentially performing cleaning, blanching, cooling and draining on the green sword beans obtained in the step (2), then performing vacuum cooling and quick freezing, and performing packaging. The method can effectively prevent nutrient element loss of the green sword beans, and can keep the crisp and tender taste of the green sword beans for a long time. In addition, the method is simple and convenient in process flow, and is suitable for large-scale industrialized production.

Description

technical field [0001] The invention relates to the technical field of vegetable processing, in particular to a method for preparing green food quick-frozen green beans. Background technique [0002] Green beans, also known as green beans, kidney beans, jade beans, small sword beans, etc., are rich in carbohydrates, protein and fat, and have high nutritional value. Green beans are green in color, delicious and sweet, crisp and tender in texture, without fiber feeling when eaten, and rich in nutrition, so they are loved by people from all over the world.
