⭐ Potassium Bicarbonate (Best Vegan Option)
1 teaspoon per 1 teaspoon of baking sodaPotassium bicarbonate acts chemically similar to baking soda by neutralizing acids and releasing carbon dioxide, which helps aerate the meat mixture and tenderize the meatloaf.
Use it as a direct 1:1 substitute, but ensure the meatloaf recipe has enough acidic components (like tomato sauce or vinegar) for activation.
The final product will have a similar texture and rise, with a slightly different mineral profile but no noticeable taste difference.
