Estimation of the penetration rate of humectants has been considered to be important in effective control of food processing when intermediate moisture food is manufactured by the moist-infusion method. In this study, when shark (Isurus glaucus) muscle was soaked in four common humectants (sucrose, sorbitol, glycerol, and propylene glycol), the equation of their penetration rate was drawn as a function of time using high performance liquid chromatography analysis. Penetration rates increased with soaking temperatures and decreased inversely with molecular weights of humectants. The penetrated amounts for 10% humectant solution reached about equilibrium after soaking for 10 horns and for 30% humectant after soaking for about 7 hours. In consideration with the penetration rate of the sample soaked in 10% humectant and complex solution of each 10% humectant, little difference was found between them. When the sample was soaked in 10% humectant and 30% humectant, it seemed to be able to apply the following regression equation to estimate the penetrated amounts: M = a log (c.t) + b where M = penetrated amounts; c = concentration of humectant; t= soaking time; a, b = constant and c.t should be within 10³ - 4 × 10.
