Recovery of valuable marine compounds from cuttlefish by-product hydrolysates: Combination of enzyme bioreactor and membrane technologies

摘要

AbstractRecognition of limited resources and increasing environmental pollution has emphasized the need for better utilization of fisheries by-products (e.g., heads, frames, and viscera). The present investigation explores the technical feasibility of “clean technologies”, that is, enzymatic hydrolysis and ultrafiltration to fractionate and concentrateSepiaby-products. The selected ultrafiltration membranes with intermediate molecular weight cut off allowed fractionating hydrolysates in several fractions of different molecular weights. The combined study of chromatographic data and amount of peptides quantified in permeates and retentates allowed us to study the progression of the fractionation in correlation with the increase or decrease in interesting molecules.]]>
