Study on the Different Desalting Methods of Half-Dried Grass Carp

Abstract:

In this manuscript,the effects of the different desalting methods,such as clear water immersion,desalting agent,pricking,oscillation and vacuum reverse infiltration on the salt content of the half-dried grass carp were investigated,with the electrical conductivity,soluble protein content and chromatic aberration of soak liquid as parameters. The experiment results showed that the desalination times of 3% salt content in fish were vacuum reverse infiltration < oscillation < pricking < clear water immersion. Adding 1.5% trehalose can maintain better product quality,the oscillation was an effective desalination treatment base on desalination rate and loss of nutrients, and vacuum reverse infiltration was an effective means of rapid desalting.
