a2Milk

Recently Paul's milk has been advertising on television that their milk does not contain any 'permeate'.
This has prompted me to find out exactly what permeate is??

It's apparently a watery, greenish waste product from the production of cheese - and documents obtained by the Herald reveal that it forms up to 16 per cent of the fresh milk we drink.

 Internal documents from Australia's biggest supplier, National Foods - which makes Pura, Big M, Dairy Farmers and supplies both Woolworths and Coles brand milk - reveal its milk now contains up to 16.43 per cent permeate.
I had already planned to talk about the benefits of drinking a2Milk as it is naturally rich in the A2 type of beta-casein protein.
Beta-casein is a type of protein that makes up one third of the protein in milk. It is a high quality milk protein that is a source of essential amino acids, as well as peptides.
The chief executive of A2 Milk, Peter Nathan, who said none of his milk contained permeate, described the substance as a "lemony-green liquid substance; it's certainly not attractive''. He said consumers were "being led to believe that milk they are drinking is pure milk. It's not".
However, the labels on milk diluted with cheap permeate don’t mention it.
We have a right to know what’s in our food so that we can make informed decisions. If we’re prepared to pay more for whole milk that really is whole milk that should be our choice and if we want to buy the cheaper alternatives we have a right know how much is milk and how much is permeate.
