Artisan dairy manufacturers have started trials using cold-pressed raw milk, recently allowed for sale in New South Wales.

The product, sourced from jersey cows at Berry on the Mid South Coast, is processed using a cold water technique to pressurise bottles.

“The bottles go into a large pressure chamber,” company founder Saxon Joye said.

“We start injecting water into the chamber through a series of pumps and then we really grind water in there.

“We’re actually compressing the bottle and the liquid inside it, between 12 per cent and 15 per cent for a few minutes.”

Mr Joye said the process aimed to remove any contaminants from the milk, without comprising its taste or colour.

I don’t really understand what’s happening there.

Seems they are saying they subject the milk to pressures of around 300 MPa and that this destroys the bacteria.

I don’t think Mr Joye does either, unless he means “compromising its taste or colour “ ;)

One of the farmers doing this was on morning TV a couple of weeks ago. He was very persuasive about the process being as efficient as pasteurisation. The presenters drank it and they’re all still alive.

as i understand it too – they discovered a few years ago that putting liquids under pressure bursts the cells of bacteria , not sure about virus

But were they pregnant?

Not that I’m aware of.

The guy did explain the process but I couldn’t hear it over the squeals of an unnamed toddler.

I’d ask them if they know how life survived snowball earth.

Wouldn’t the pressure bust the bottles? It sort of sounds like a Fowlers Vacola method of doing preserved fruit, but there is heat involved in that. I don’t understand at all.

I was actually trying to find real science. Can’t find much. Did find this, which does mention a relevent sciency person. But not many.
