Abstract

Disclosed is a method of preserving root dewatering. Its job step is: choose root; wash; cut its skin and dip it in vitamin C aqueous solution 2-3íÙ in weight; cut it into different shapes; put it in sodium hypochlorite solution 100PPM-300PPM in weight and sterilize for 5 minutes, and then wash it in water after sterilize in ultraviolet ray; put it in the cold house of 30-40 deg.C cool it for 9-14 hours; Then put it in the vacuum house for drying; keep the shape and crush, use the vacuum pack. The invention can keep it original color and shape; taste is the same to the fresh root not damage to the nourishment; long term to keep; preservation is not limited by conditions, and it is convenient to take.

Description

technical field [0001] The invention relates to a method for preparing dehydrated and preserved vegetables, in particular to a method for preparing dehydrated and preserved burdock root. Background technique [0002] Burdock root belongs to Compositae, a biennial herb plant, rich in various vitamins and minerals needed by the human body, its carotene content ranks second in vegetables, 150 times higher than that of carrots, and the content of protein and calcium is the highest among rhizomes.
