AGE GELATION IN LONG LIFE MILK.

The Dairy Industry loses millions of Rand per annum due to age gelation of milk that reduces its shelf life. Age gelation can be induced by anything that has an impact on the suspension of the negative charge on the casein micelle during storage of long life (UHT) milk. This includes the enzymatic or chemical processes that occur during storage. The enzymatic processes involve the action of plasmin (native enzyme) or heat stable microbial proteases.

PRIORITIES TO BE ADDRESSED IN THE INDUSTRY TO SUPPORT SUSTAINABILITY.

Competitiveness is a function of efficiency, market access (broadening of the market of dairy products is a primary goal) and sustainability. In addition to volatility, structural and consumer needs of markets which with up-to-date information can be addressed only partially, sustainability is progressively also influenced by issues which can be categorized within the three P concepts: Productivity (economic focus), People (sociological focus) and Planet (environmental stewardship focus).
