Yes, you can freeze soy milk. However, be aware that freezing and thawing will alter its texture.
How to Freeze Soy Milk
Freezing soy milk is similar to freezing cow's milk. Simply pour the soy milk into a freezer-safe container, leaving some headspace for expansion. Freeze until solid.
What Happens After Thawing?
After thawing, the soy milk may separate and appear curdled or grainy. Don't worry! This is normal. Simply shake or blend the soy milk vigorously to restore its original consistency. The color might also change slightly; some sources report a shift to a lighter coffee color.
Shelf Life After Freezing
Frozen soy milk can last for 3-6 months. However, for best quality, use it sooner rather than later.
Different Types of Soy Milk
The freezing process may affect homemade soy milk and commercially produced soy milk similarly, though some variations are possible depending on ingredients and additives. Unsweetened soy milk generally freezes and thaws similarly to sweetened varieties.
