Abstract:The main nutrients such as protein，carbohydrate，fat，mineral and amino acid in wheat and buckwheat sprout powder were systematically analyzed and compared with five common vegetables such as cabbage and rape to clarify the nutritional characteristics of two kinds of sprout powder.Amino acid ratio coefficient method was used to evaluate the nutritional value of protein.The protein，dietary fiber，and ascorbic acid content of the two sprout powders were significantly higher than those of the five common vegetables.The two kinds of sprout powder were high-potassium，low-sodium，and low-fat foods and contained 18 amino acids.The total amino acids contents in wheat and buckwheat sprout powder were 31.55 g/100 g and 21.99 g/100 g，respectively.8 essential amino acids were contained in wheat and buckwheat sprout powder and scores of ratio of amino acid coefficient values were 63.52 and 77.03，respectively.The protein contents in wheat and buckwheat sprout powder were close to the egg protein（protein standard），the close degrees were 0.95 and 0.91，respectively.The six free amino acids，such as Ala，His，Glu，Asp，Arg and Cys，were the main amino acids that form the flavor of the two kinds of sprout powder.All of the results showed that two kinds of sprout powder had high nutritional value and were edible high-quality protein sources.
