Abstract: The research was carried out in 2002-2006 at the Crop-Growing Product Storage and Processing Laboratory, Department of Horticulture, Lithuanian University of Agriculture Animal Husbandry Institute of Lithuanian Veterinary Academy. 15 amino acids were determined in the studied samples of potato tubers of 5 cultivars including 9 essential amino acids. Essential amino acids make up 38-45% of all the amino acids. In potato tubers, the dominating amino acids were leucine and valine, the lowest amount was of methionine and histidine. Dominating alterable amino acids were glutamic and aspartic acids. The latter were one of the most mobile during the storage period. During the whole period of storage, the lowest changes were observed in the following: lysine in cv. Goda tubers, histidine in cv. Nida tubers, methionine, histidine and isoleucine in potato tubers of the cv. Vaiva. Alterable amino acids, i.e. glycine, alanine and tyrosine, during the whole period of storage changed the least in the potato tubers of all cultivars. The decrease in the protein content during the storage period causes the increase in the tyrosine content. Tyrosine is not desirable in potato tubers due to the fact that it negatively affects the color of raw potato tubers
