Signs of Spoilage
Bulging container, severe separation that doesn't mix back in upon shaking, unusual discoloration visible through the container, foul odor detected if the container is compromised.
How to Check
Check the 'best by' or 'expiration' date on the packaging. Inspect the container for any signs of damage, leaks, or bulging. If the sauce appears to have separated excessively and doesn't recombine with shaking, or if there are noticeable changes in color, it's best to discard it.
Storage Tips
Store in a cool, dark place away from direct sunlight and heat fluctuations to maintain quality. While often safe past the 'best by' date, quality (flavor and texture) may degrade over time.

Signs of Spoilage
Visible mold growth (fuzzy spots of any color, often white, green, or black), significant discoloration (darker or lighter patches), strong off-odor (sour, fermented, yeasty, or putrid), unusually thick, gummy, or excessively watery texture, fizzy appearance or bubbles indicating fermentation.
How to Check
-
Visual Inspection: Open the container and look closely for any signs of mold on the surface, around the rim, or within the sauce. Check for unusual color changes or separation that cannot be stirred back into a uniform consistency.
-
Smell Test: Hoisin sauce has a distinct sweet, savory, and slightly tangy aroma. If it smells sour, yeasty, alcoholic, or otherwise unpleasant and 'off', it has likely spoiled.
-
Texture Check: If the sauce has become unusually thick, gummy, or slimy, or if it's excessively watery and doesn't mix, it's a sign of spoilage. Do not taste if any of these signs are present.
Storage Tips
Always use clean utensils to avoid introducing bacteria. Keep the lid tightly sealed after each use. Store on an inner shelf of the refrigerator where temperatures are most consistent, rather than in the door, which experiences more temperature fluctuations. Discard immediately if mold is present, as it can spread below the surface even if only visible in one spot.
