Soy milk

Storage Time

Unopened UHT (shelf-stable) soy milk can last 6-12 months in the pantry until its 'best by' date. Unopened refrigerated soy milk typically lasts 7-10 days past its 'best by' date. Once opened, all types of soy milk should be consumed within 7-10 days when stored properly in the refrigerator. For extended preservation, soy milk can be safely frozen for up to 3-6 months.

Temperature

Keep unopened UHT soy milk in a cool, dark pantry. All opened soy milk, and all refrigerated varieties, must be stored in the refrigerator at a consistent temperature of 0–4°C (32–40°F).

Freezing

Yes, soy milk can be frozen, though its texture may change slightly upon thawing, potentially becoming a bit grainier or separating. To freeze, pour soy milk into airtight, freezer-safe containers or ice cube trays, leaving about an inch of headspace to allow for expansion. Once frozen solid, transfer cubes to a freezer bag for convenient portioning. Thaw frozen soy milk overnight in the refrigerator. Stir or shake vigorously before use to reincorporate any separated solids. It's best utilized in smoothies, baking, or cooking after thawing, as the texture may not be ideal for drinking straight.

Signs of Spoilage

• A sour, rancid, or otherwise off-putting smell, distinctly different from its usual mild aroma.
• A thickened, lumpy, or curdled texture, indicating bacterial growth and protein coagulation.
• Discoloration, such as a yellowish tint, or the visible presence of mold on the surface or container.
• An unusually bitter, acidic, or unpleasant taste, even in small sips.
