Challenge and opportunities in the recovery of high value biological and functional proteins and peptides- A review

Abstract

Wastewater from canning or fishmeal industries is considered a good source of several chemical compounds. To reduce the negative impact of these effluents on the marine ecosystems different techniques have been developed to remove solids, as well as to recover nutrients, like proteins, which can be employed in industries like food, agrochemical, or pharmaceutical. These proteins can be concentrated by ultrafiltration and nanofiltration systems. This methodology allows proteins with better nutrition quality and biological activities. This review examined and discussed several treatment technologies applied to recover solids from the canning and fishmeal industries, also the opportunity for the extraction of chemical compounds. Highlight in discussion the potential applications of the ultrafiltration on recovering functional and biological proteins from wastewater fish industries.
