Evaluation on performance of dead-end ultrafiltration membrane in fractionating tilapia by-product protein hydrolysate

Conversion of tilapia by-products through enzymatic hydrolysis is a promising alternative to produce a fish protein hydrolysate (FPH). Tilapia by-product (TB) protein hydrolysate consists of peptide mixtures in various sizes. Recovery of small-sized peptides is increasingly becoming a priority due t...
