The fining efficiency of different samples of isinglass finings is related to the molecular weight of the finings molecules in true solution, those of highest molecular weight being the most efficient. The molecular weight is studied by means of intrinsic viscosity. Contributions from soluble aggregates are avoided by carrying out the measurements in citrate buffer. Soluble aggregates occur in finings but do not contribute to fining. The significance of intrinsic viscosity and soluble collagen content in the preparation of finings is examined.
