An excessive amount of edible alkali added to food does not usually lead to poisoning, but some adverse reactions, such as stomach pain, indigestion and heartburn, may occur. Edible soda, scientifically known as sodium carbonate, is mainly used in pasta made by adding soda when mixing noodles. Edible Soda is a meat tenderizer and food fluffing agent commonly used in daily life, which can quickly make dry ingredients rise and remove the acidic smell produced by dough fermentation, such as common noodles, bread, steamed bread, etc. Adding soda to noodles can neutralize the acid produced by yeast during the process of noodle making. The dosage of edible alkali added to food is limited and generally does not lead to toxicity in excess. However, if a large amount of edible alkali is consumed at one time, it may cause adverse reactions, such as damage to the gastric mucosa, resulting in symptoms of heartburn, and the damage to the stomach will affect the body’s absorption of minerals and vitamins, increasing the risk of malnutrition in the organism. It is recommended to use edible alkali within a reasonable range and avoid adding excessive amount. If too much edible alkali causes discomfort, please seek medical attention.
