摘  要:
A liquid product of barley green was prepared from buckwheat seedlings by the steps of freezing wall breaking,extraction with 1/150 mmol/L phosphate buffer containing 0.01% sodium erythorbate by grinding,vacuum concentration and instantaneous ultra-high temperature sterilization.The freezing wall breaking extraction of buckwheat seedlings was optimized by orthogonal array design.Under optimized conditions,the contents of protein,chlorophyll and rutin and the SOD activity of barley green extract were 0.26%,9.37 mg/100 ml,1.03 mg/100 ml,and 242 U/100 ml,respectively.Other indexes of the product obtained were in accordance with the national standards for plant health products.
