Development of Salt-sensing System for Jellyfish Desalting Process

Abstract

In the seafood industry, a large amount of salt is added to preserve seafood products.During processing, it is necessary to desalt the products for the sake of customers' health.Unlike a large-scale factory, many small enterprises lack tools and methods for desalting and measuring the efficiency of the desalting process.We have developed a rapid prototype salt-sensing system that can measure the desalting efficiency.Dried salted jellyfish are used as testing materials to evaluate the system.The rapid prototype comprises a microcontroller, a wire, and a liquid crystal display.Using a simple mapping between electrical conductivity and actual data obtained from the measurement of samples, the sensing system is successfully calibrated.A method of desalting the salted jellyfish material is also proposed.This desalting method and the newly developed simple sensing system for the desalting process are expected to make a significant contribution to the seafood processing industry.
