Role of Raw Milk Quality in UHT Production SRIHARSHA KOSHTI Country Marketing Manager (South Asia Markets) Givaudan, Mumbai March 5, 2019 Milk quality starts at the farm with animal health and good hygiene. As soon as milk leaves the animal, it is subject to contamination by microorganisms that will start to multiply and that will greatly affect its suitability for production of UHT milk and other milk products. Milk quality affects the efficiency and cost-effectiveness of the plant’s processing machinery. Poor quality milk can clog heat exchangers, causing processing interruptions and requiring extra cleaning time—and thus extra costs.
