With respect to the procedure of removing soluble calcium from milk as insoluble salts, experiments were performed with skimmilk, and it was seen that oxalate was able to be adapted for the purpose while sulfate was unsuitable. Then by means of potassium oxalate, decalcified milk was obtained from skimmilk, from which calcium was removed in various proportions and its coa-gulability by rennet was experimented precisely. As the result it was found that (a) there was a parabolic relation within a certain limit between the rate of decalcification of milk and coagulation times by rennet, (b) removing 20 to 25% a of total calcium in milk, the milk should become practically not coagulable by rennet, and (c) adding soluble calcium salts to the decalcified milk, its coagulability was recovered and in these relations calcium acted quantitatively as for milk coagulation.
