Values (mg/g dry weight) are the means ± SD (n = 3). Means with different letters with a row are significantly different (P < 0.05). 5′-AMP, 5′-adenosine monophosphate; 5′-CMP, 5′-cytosine monophosphate; 5′-GMP, 5′-guanosine monophosphate; 5′-UMP, 5′-uridine monophosphate; 5′-IMP, 5′-inosine monophosphate. Flavor 5′-nucleotide, 5′-GMP + 5′-IMP.
