A rapid turbidimetric method for the determination of the precipitation curves of carrageenans

A rapid turbidimetric method for the determination of the precipitation curve of carrageenans is proposed. It is based on the precipitation of a solution of carrageenan, under standard conditions, at a given concentration of potassium chloride and the measurement of the turbidity produced. The preci...
