Notes:
During the action of crystalline rennin on solutions of α-casein, Non Protein Nitrogen (NPN) soluble in 12% trichloroacetic acid is split off. The NPN/time curves greatly resemble the ones obtained by Alais, Mocquot, Nitschmann & Zahler for whole casein. Both primary reaction and general proteolysis are clearly recognizable. β-casein under the same conditions shows only the general proteolysis (straight NPN/time curve). As is known, the α-casein alone is responsible for the curdling of milk under the action of rennet. These results, therefore, support the assumption that the specific splitting reaction, which sets free a small amount of NPN very quickly, is directly responsible for the milk clotting.
