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.

Highlights

  • “Perico" (Coryphaena hippurus) is the second largest artisanal fishing resource in Peru, and an important export product [1]

  • Ice slurry is made of ice microcrystals suspended in an aqueous solution

  • Even though different studies have been done on ice slurry and its properties for seafood cooling, no literature has been found regarding the production costs of ice slurry with different ice mass fractions for artisanal fishing applications

Summary

Introduction

“Perico" (Coryphaena hippurus) is the second largest artisanal fishing resource in Peru, and an important export product [1]. This technology does not guarantee the innocuity and integrity of marine foods for a long time During storage in these conditions, bacteria develops and the fish visual appearance deteriorates: its skin undergoes noticeable changes, like the loss of its shine and the thickening of the viscous layer that surrounds it, and their eyes wrinkle and sag [2] [3]. Since its skin is soft and damaged, storing fish on ice exposes it to rough conditions that can cause the contamination of its meat with bacteria [4]. For this reason, researchers searched for new techniques that could solve these problems and found a solution in ice slurry. Different studies have concluded that ice slurry reduces the growth of microbes in seafood, and that it extends its shelf life, allowing consumers to enjoy marine products in good conditions [6] [7]
