The Proper Degree of Ripeness.—At the time when the starter milk begins to be sour to the taste, but has not reached the coagulating- point, it usually has a peculiarly disagreeable odor and flavor. This is explained to be due to the activity of other micro-organisms aside from the lactic acid species in- oculated. Later, w^hen the acid is more pronounced and the milk is at the point of curdling, this disagreeable flavor and aroma generally disappear, the lactic acid species of bacteria having gained the ascendancy, holding the other species in check. If the starter v\'ere therefore used in the early stage of acid development and before the battle of species for the survival of the fittest had been decided in favor of the lactic acid organisms, the starter would fail to lend to the cream and the resulting butter the flavor for which it is used. It is important, therefore, to permit the starter to develop until the maximum number and activity of lactic acid bacteria are secured, which is the case usually at the point when the milk commences to Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Hunziker, Otto Frederick, b. 1873.
