Abstract: In order to study the quality changes in the process flaxseeds' germination and achieve the high value-added utilization of the new resource product-flaxseed sprout. By measuring the content of protein,fat,amino acids,vitamins,minerals and cyanide,the contents of nutrient composition of flax seed germination before and after were analyzed. The results showed that after germination the cyanide content reduced by 8.95%,the fat content decreased by 23.60%,the protein content increased by 57.77%,the total number of amino acid increased by 61.67%,the total amount of essential amino acids increased by 62.77%. And the content of vitamins increased substantially,up to 77.37 mg/100 g. And minerals including Ca,Mg,K,Zn and Cu increased by 126%. Germination could improve the nutritional value of flaxseed.
