2 Milk Flavor is the key to popularity. Judging begins on the farm (at the point of production) Continues in the commercial dairy plant at various check points then as a finished product.

3 Distinguishing Tastes Four primary tastes: –Sweet-produced by sugar; noted at tip of the tongue –Sour-lactic acid or tart apple; along sides of tongue –Salt-common salt; sides and tip of tongue –Bitter-quinine; base of tongue

5 Factors Affecting a Judge Illness ‘Memory” taste Personal practices-tobacco, it dulls the senses Strongly scented soaps, lotion, hair products, or perfumes. Strong foods-onions, chili, chewing gum.

6 Judging Milk Flavors are caused by five factors: –health of cow –feeds consumed by the cow –bacteriological action –chemical changes –absorption of foreign flavors after the milk is drawn

7 Judging Milk Bitter –strong feeds or weeds which may carry through to the milk –conditions present in milk from cows in late lactating –bacterial growth, but normally won’t happen unless several days of warm temperatures –sometimes confused with rancid milk; but only detected by taste, not smell.

8 Judging Milk Cooked –results from heating Feed –green grass, silage, turnips, and alfalfa can carry through to milk –take cows off feeds at least 4 hours before milking
