E515, or sodium metaphosphate, is a food additive widely used in the food industry as a stabilizer and acidity regulator.
Sodium metaphosphate is not a dangerous substance when consumed in moderation.
However, like any food additive, daily consumption of E515 may have a negative impact on the body.
Sodium metaphosphate is most commonly used in meat and fish products, canned goods, dairy products, beverages, baked goods, and gelatin desserts.
