A major milk producer will follow in the footsteps of an independent and stop using a thinner in two top milk brands.
The watery dairy by-product used by milk producers to dilute protein levels, known as permeate, will no longer be added to some Dairy Farmers and Pura milk products from July.
A spokeswoman for Lion, which produces both Pura and Dairy Farmers milk brands, said the milk makeover comes after consumer demand for less processed products that were as close as possible to original farm-produced milk.
"We looked at our manufacturing process and realised that adding permeate was not essential, so it was an easy decision to remove it from our milk," Lion spokeswoman Libby Hay said in a statement.
"By not using permeate, the natural seasonal variations in protein will flow through into our rich, creamy milk, providing a product that is the purest quality milk."
Independent home supplier Aussie Farmers Direct chief executive Braeden Lord said his company had been using permeate-free milk since they started producing milk a year ago.
"We wanted to do the right thing for our farmers and customers by shunning modern practices to increase volumes by adding permeate," Mr Lord said in a statement.
Mr Lord said he found many Australians were shocked to find milk could contain up to 12 per cent permeate.
