Some common questions about milk and permeate...
There is nothing in fresh milk that is not milk. No matter what product you choose, you can be assured it is a high quality and nutritious product containing all the 10 essential nutrients that milk naturally provides.
Permeate is simply a collective/technical term for the lactose, vitamin and mineral components that are a natural part of milk, extracted using ultra-filtration. This is why it is not labelled
The lactose level does not change from the stated value on the label. The whole point of standardisation is to keep nutrients in milk at a consistent level.
Milk permeate is NOT a by-product of cheese.
Consistent composition levels in milk are required to make the wide range of healthy and nutritious types of milk for consumers. Variation in the composition of the milk can change the taste and functional properties of the final product and can lead to difficulties during processing.
In cheese-making, the milk standardisation process happens before the cheese is made. Cheese production requires a consistent composition of milk with regards to its ratio of fat to protein that will ensure the taste and functional properties of each type of cheese are the same, no matter what time of the year it is made. This is when various technologies, like ultra-filtration, are used to standardise the milk components.
The use of such technologies also ensures every component in milk is used efficiently to maximise the yield of milk with no waste.
Certainly not – Permeate is a term that refers to a collection of valuable milk components containing lactose, vitamins and minerals. Through innovation, the dairy industry has been able to develop processes that allow standardisation of milk composition and create a range of innovative dairy products and use every part of this nutritious product.
As permeate is simply a collection of milk components (lactose, vitamins, minerals and water), naturally these will be found in milk according to the variety. We encourage consumers to contact the manufacturer of their favourite brand for further product information.
