Optimal design of industrial scale continuous process for fractionation by membrane technologies of protein hydrolysate derived from fish wastes

Abstract

Highlights-Fractionation process by UF and NF membrane cascades of a fish protein hydrolysate -Basic integrated cascade identified as the most convenient configuration -Freshwater consumption was avoided by implementation of water recovery and reuse system -Product valued above the 95-212 $/m 3 range compensate the costs of the fractionation process

Production of fish protein hydrolysates step by step: technological aspects, equipment used, major energy costs and methods of their minimizing

“…Micro-, ultra-and nano-filtration After plate and frame filtration, when bigger particles are caught by the filters, the protein mixture can be delivered to membrane filters for careful fractionation or concentration of FPH mixture. Membrane filtration is a useful tool for obtaining certain groups of peptides utilized for different purposes (for example, bioactive peptides) (Abejón et al 2018).…”

“…4). Peptides in FPH slurry can be also separated by membranes based on their charge and hydrophobicity characteristics (Abejón et al 2018). Membranes are made of nylon, polyethersulfone, polyvinylidene difluoride, polytetrafluoroethylene, mixed cellulose ester, cellulose acetate, polypropylene and other material (Microlab Scientific 2018).…”

“…Microfiltration is not a popular method utilized by researchers for the filtration of FPH, probably, due to the aimed particles to be plugged (the most bioactive peptides) are usually with a smaller size (B 4 kDa) (Abejón et al 2018;Saidi et al 2014;Vandanjon et al 2009), than microfilters can retain. The filtration range of microfiltration is generally less than 100 kDa, which is far bigger than the aimed peptide size.…”

“…The filtration range of microfiltration is generally less than 100 kDa, which is far bigger than the aimed peptide size. By contrast, ultra-and nano-filtration is recently investigated in a large number of research articles on FPH (Abejón et al 2016(Abejón et al , 2018Bourseau et al 2009;Roslan et al 2018;Saidi et al 2014;Vandanjon et al 2009) or was used as a filtration tool in other investigations of FPH (Abdelhedi et al 2018;Halim et al 2018).…”

The Effect of Cross-Linking with Citric Acid on the Properties of Agar/Fish Gelatin Films

“…According to recent findings, fishery discards account for slightly less than 10% of total annual catches, which correspond approximately to 10 Mt/year [8]. Furthermore, fish processing wastes include large quantities of substandard muscles, viscera, heads, skins, fins, frames, and trimmings, which generally account for 30-50% of the total weight of the starting material [9]. These fish wastes represent a source of several potentially valuable molecules [2]-among them, gelatin [10], a protein with unique functional and technological properties.…”
