Abstract: | The profile and levels of free amino acids and bioactive amines in fermented milk were investigated. The five most widely consumed products were obtained immediately after production from the consumer market, and were analyzed throughout shelflife at 15 days intervals for free amino acids and free bioactive amines (UPLC after derivatization with 6-aminoquinolyl-N-hydroxysuccinimidyl carbamate). pH and titratable acidity were also analyzed. Throughout shelf life, fermented milk had mean pH from 4.00 to 4.04 and acidity of 0.98 and 0.99 g lactic acid/100 g for products A and B, respectively. Fermented milk A contained three free amino acids: asparagine, arginine and proline; whereas B had 11: aspartic acid, alanine, arginine, asparagine, histidine, isoleucine, leucine, phenylalanine, tyrosine, threonine and valine. Total amino acids were 4.2 and 17.8 mg/kg, respectively. Both products contained spermine (the only amine detected among nince investigated), at levels of 0.7 mg/kg. |
