spoiled milk

[jordehwa]

HI

 

I was wondering if i let milk spoil for a while and then filtered the curds out and distilled the liquid would that give me a clean solution of lactic acid.

[jordehwa]

Please answer if you know this is important to me.

I think it would give you impure lactic acid..

[jordehwa]

thanks for answering also do you know how i can get a pure lactic acid

I heard you can get it by fermentation of pure lactose sugar in water but how do i do that

[StringJunky]

Wouldn't it be easier and purer to buy it or is it the actual process you need to know for your education?

 

What purpose do you have for it...if you provide more detail as to its final spec (concentration and purity) someone might help you?

[Mr Skeptic]

It will still have water soluble proteins in it.

you might be able to do better by culturing lactobacillis directly.

[jordehwa]

ok thanks guys.

You can just buy ethyl lactate by the quart in some hardware stores. It's touted as a green/renewable paint stripper I believe. You'd have to cleave the ester, such as with NaOH, but such a solution, if lacking excess NaOH would be fine for preparing metal lactates.

Oh really thanks UC:D
