Common Mistakes When Checking Miso Paste
- Confusing "Non-Dairy" with Vegan: Products marked "non-dairy" (like coffee creamers) frequently contain casein or whey derivatives derived from cow's milk.
- Overlooking Processing Aids: Items like refined white sugar, traditional wines, and cask ales may look vegan on the ingredient label but involve bone char or fish isinglass during manufacturing.
- Ignoring Regional Sourcing: Additives like mono- and diglycerides (E471) or Vitamin D3 can be plant-based in one country and animal-derived in another unless explicitly certified vegan.
