Figure 4

Size exclusion chromatography analysis of the molecular mass distribution of fish skin hydrolysates at laboratory (a), pilot (b) and plant (c) scales. Values above the peaks indicate the retention times of the standards. The retention times for the standards Tripeptide GGG (Mr 189), tetrapeptide GGYR (Mr 451), bacitracin (Mr 1422), aprotinin (Mr 6511) and cytochrome C (Mr 12400) are 20.216 min, 18.001 min, 16.127 min, 14.251 min and 12.316 min, respectively. (Inset) Contents of peptides in different molecular mass ranges in the hydrolysates at laboratory, pilot and plant scales.
