Abstract:The content and components of amino acids were determined in the black and white sesame materials at 0，1.5，3，5，7 d and 9 d after germination.The result showed that the sesame sprouts were rich in 18 kinds of amino acids.The content of total amino acids（TAA）in the relative dry weight of sesame sprouts showed a parabolic increasing trend with the prolonging of germination time.The value of TAA in black and white sesame sprouts increased up to the highest value at the 7 d and 5 d after germination with a growth of 69.41% and 39.82% higher than that in its seed，respectively.Furthermore，the ratio of essential amino acids to total amino acids（EAA/TAA）in sesame sprouts increased from about 32.0% at the beginning to about 40.0% after germination.At this time，the protein nutrition in sesame sprouts has met the ideal protein requirements proposed，which was a very high-quality protein plant resource.By comparing the taste activity value（TAV）of each taste amino acid，the first two amino acids that had the largest effect are bitter arginine and umami glutamic acid，respectively.
