Fig. 3From: Changes in free amino acids and hardness in round of Okinawan delivered cow beef during dry- and wet-aging processesChange in levels of each amino acid group in both types of beef during both dry- and wet-aging processes. Amino acid groups are classified as sweet-, umami-, and savory-tasting and functional. The sum of sweet-, umami-, and savory-tasting amino acids constitute the proteinogenic category. Changes in their levels during the dry-aging process are shown by solid lines. Changes in their levels during the wet-aging process are shown by dotted linesBack to article page
