Master batching Lye with goat milk?

[Sharryn]

I made my first goat milk a couple days ago and am anxious to make another. I just read about master batching your lye and wondered if it could be done with goat milk. Does the lye chemically change the milk so that it wouldn't sour or curdle? I would love to master batch but not sure if this is possible with milk.

 

[Arimara]

I would not try it. Water is one thing but any kind of milk still has components prone to spoilage.

I don't know of anyone who has done this, but that doesn't mean it can't be done. If this is something you want to do, give it a try and see what happens.

Even so, I agree with Arimara -- I would be concerned that milk in long contact with concentrated alkali may do strange things.

I would guess your are going to end up with some chunks of soap in your masterbatch due to the fat in the GM

 

[BrewerGeorge]

It will not "spoil" in the classic sense, as that is bacteria (typically lactobacillus) driven and nothing alive is going to remain so in a 50% lye solution. But I think the others are right that the fats will turn to soap and the proteins will get weird over time.

I wouldn't try it.

I personally wouldn't do it. Lye will react with the fat in the milk and saponify it, leaving you not so much with a lye solution, but something more like a gloppy, thickened gel of unknown strength I can only imagine. Distilled water is the best liquid to use if you ask me.

Yeah, I didn't see where anyone else had done it, but had to ask the "pros"

Thanks for all your input.

Has anyone tried freezing a goat milk / lye masterbatch?

 

[Susie]

No, but the same issue would happen. Saponification of the fats in the goat's milk.

Rather than trying to masterbatch the goat's milk, why not use the split method and add masterbatched NaOH/water and either evaporated goat's milk, or goat's milk powder added to the oils?
