freezing point of kalk

[salty joe]

I was looking at a thread about feeding almost frozen food using a mini fridge and peristaltic pump.
Would diluting the frozen food with kalkwasser (instead of RO/DI water) lower the freezing point of the slurry?

I could not find the freezing point of calcium hydroxide online...Also not sure how it would affect the nutritional value of the food but I think it has preservative qualities, not sure about that though.

Saturated limewater (kalkwasser) is not very concentrated, and the freezing point depression, relative to pure water, is much less than 1 degree C.

Thanks.

You're welcome.
