영문 초록

Adaptation experiments of silver nitrate-agar gel diffusion method for measuring chloride ion concentrations in physiological fluids to the microdetermination of milk chloride ion were described. The method based on the chemical precipitation of silver chloride by radial diffusion through agar gel containing silver nitrate was simple to run and required only 10㎕ of milk when especially low concentrations of 86-114㎜/ℓ silver nitrate solution in the preparation of silver nitrate-agar gel plates were added and proved that diffusion of chlorides to the siver nitrate-agar gel were not interfered by milk components. Raw milk taken from 61 different dairy pastures gave mean value of 98.65㎎/100㎖ chloride ion and average of chloride ion concentrations obtained from 80 market milk samples pasteurized by 8 different milk plants were lower as 85.76/100㎖ than raw milk.
