Milk and its products are ideal foods for the elderly, women, children and patients, but they are easy to deteriorate. The identification of hygienic quality of milk and dairy products can be carried out in the following ways.

Fresh milk: a white or yellowish uniform suspension with normal sensory characteristics, without clots and impurities, with a slightly sweet and unique fresh milk aroma. If the color of milk is found to be gray, yellow or red, and it has a sour taste, it means that the milk has gone bad and cannot be drunk.

Milk powder: The normal sensory characteristics should be light yellow powder with small and uniform particles, without quick knot and peculiar smell. When buying milk powder, check whether the packaging is tight, because if it is not tight, milk powder will deliquesce easily. In addition, we should pay attention to the shelf life, and the hygienic quality of expired milk powder is not guaranteed.

Yogurt: Ordinary yogurt, with the same color as fresh milk, dense, solid and uniform clots, pure and fragrant lactic acid smell and no bubbles. When the color and taste of milk change, the clot melts and a large amount of whey precipitates, it means that milk has deteriorated and should be discarded and not drunk.

Sweet condensed milk and evaporated milk: normal sweet condensed milk and evaporated milk are even light yellow and sweet. When poured out, the emulsion flows downward in a linear or ribbon shape. If clots, mildew spots, floating fat and peculiar smell are found, it means that the sanitary quality is poor and it cannot be eaten.
