Bought unpasturised milk. Can I thaw, pasteurise and re freeze?

Hi,

I am based in the UK and bought a bottle of unpasteurised milk which I put straight in the freezer. Can I thaw it, pasteurise it and then refreeze it?

Thanks!

Is pasteurising just boiling? If there’s more to it than that I’d just go round to the shop and buy more.

Yes it’s just boiling 😊

I actually have no idea about the home pasteurising, I was just curious about what it was.

Why do you want to pasteurise it and refreeze? Just thaw it and use it.

No I don't think you can pasteurise it at home.

Boiling milk is not a good thing!

Just use it, bin it. Or. Bored in lockdown, try to make cheese or yoghurt?

Unpasteurised milk bought in the UK won't do you any harm tbh.

'The process of pasteurisation involves heating milk to 71.7°C for at least 15 seconds (and no more than 25 seconds). Because of the nature of the heat treatment it sometimes referred to as the 'High Temperature Short Time' (HTST) process. Once the milk has been heated, it is then cooled very quickly to less than 3°C.'

Easier just to use it

Boiling milk produces STERILISED milk - this is the long-life version you find in supermarkets outside of the refrigerator.

As the poster above points out, pasteurisation involves heating to a precise temperature for a precise time period - trying to do this at home would likely affect the flavour.
