Summary

With the global population continually expanding, the search for sustainable sources of high-quality protein has become increasingly urgent. Fish side streams, constituting 60–70% of the total fish population and rich in essential nutrients, emerge as a sustainable reservoir for recovering valuable protein compounds. The production of fish protein hydrolysate is a form of fish waste utilization with the potential for significant added value. Liquid FPH, a water mixture of hydrolyzed proteins, initially contains 84 to 95% moisture content. The drying process for fish protein hydrolysates is known to be energy-intensive, and the introduction of freeze concentration in the drying line offers a promising approach to reduce energy demand significantly. This study simulates the fish protein hydrolysates crystallization process using Ansys and MATLAB. The study concludes that achieving a concentration of 42% is feasible, which eliminates the need for an evaporator in the drying line. This finding suggests significant energy-saving potential, estimated at up to 30%.
