Production cost of ice slurry using a saline solution and different ice mass fractions, applied to “Perico” (Coryphaena Hippurus) artisanal fishing in Peru

Abstract

An experimental study was carried out to determine the production costs of ice slurry, using a saline solution with different fractions of ice, for “Perico” (Coryphaena Hippurus) artisanal fishing in the Peruvian sea. A 3-kW ice slurry generator, portable enough to fit in an artisanal boat, was used. The prototype was instrumented with sensors for temperature, density, and electrical parameters (voltage, current, power) measurement in order to determine the ice mass fraction and production costs. The results indicated that not only ice slurry ensures a higher cooling speed and less damage to the product, but also, its production costs are lower compared to flake ice.

Study on the quality of fish products based on different preservation techniques: a review

“…Nevertheless, the CO2-modified RSW induced sensory alterations in the fish during frozen storage by increasing salt absorption and increasing rancidity (Ashie et al, 1996). Ice slurries, also known as flow ice, have been utilized more lately (Andrzejewski et al, 2010;Guzmán et al, 2021;Keys et al, 2018). Because of their greater heat exchange capacity, these water-ice systems may achieve temperatures below zero faster, protecting the fish from oxidation and dehydration.…”
