Characteristic analyses of fish skin hydrolysates prepared at laboratory, pilot and plant scales. (a,b,c) MALDI-TOF-MS analysis of the molecular weight distribution of peptides in the hydrolysate from laboratory (a), pilot (b) and plant (c) scales. Inset, solution of the hydrolysate (20 mg/mL). (d) RP-HPLC analysis of the peptide spectra of the hydrolysates from different scales.
