Optimum Thermal Processing for Extended Shelf-Life (ESL) Milk

Robinson: Modern Dairy Technology pp Cite as. Milk is extremely perishable, yet for a number of reasons it is desirable to preserve it for later consumption. Today, drying is the most important method of preservation. The advantage is that using modern techniques, it is possible to convert the milk to powder without any loss in nutritive value, i. The disadvantage is that drying consumes a lot of energy; in fact, no other process in the dairy industry has a higher energy demand per tonne of finished product.

The heat used during the UHT process can cause Maillard browning and change the taste and smell of dairy products. UHT milk packaged in a sterile container has a typical unrefrigerated shelf life of six to nine months. In contrast, flash pasteurized milk has a shelf life of about two weeks from processing, or about one week from being put on sale. The most commonly applied technique to provide a safe and shelf-stable milk is heat treatment. However, without commercially available aseptic packaging systems to pack and store the product, such technology was not very useful in itself, and further development was stalled until the s.

By Niamh Burke, Krzysztof A. Ryan and Catherine C. Sampling and analysis occur along the milk processing train: from collection at farm level, to intake at the diary plant, the processing steps, and the end products. Milk has a short shelf life; however, products such as milk powders have allowed a global industry to be developed.

Это был шантаж. Все встало на свои места.

    The principal constituents of milk are water, fat, proteins, lactose milk sugar and minerals salts.

    Extended shelf-life ESL or ultra-pasteurized milk is produced by thermal processing using conditions between those used for traditional high-temperature, short-time HTST pasteurization and those used for ultra-high-temperature UHT sterilization.
