In these days of expanding geographical markets for milk products, and the uncertainty of chilled distribution in many parts of the world, UHT milk is being transported further and further away from its production origins and may even be at sea for several months. In these cases, predictable shelf life and sustainable quality are paramount to consumer satisfaction. European exports to China, for example, need to have additional shelf life to cover the transport plus the consumer distribution chain. For extreme storage conditions like longer shipping voyages, temperature fluctuations can cause both visual and quantitative changes in creaming. Dairies planning for longer transports should take this into account during production.
