E355, or sodium citrate, is a food additive often used in the food industry as a preservative and acidity regulator.
Sodium citrate itself contains no carbohydrates, making it relatively safe for consumption on a keto diet.
Sodium citrate is commonly used in the production of cheeses, confectionery, beverages, canned goods, and other products.
It helps control the acidity levels of products, enhances their flavor qualities, and extends shelf life.
In addition to the food industry, sodium citrate is also used for medical purposes, such as regulating urine acidity or as a component of infusion solutions.
Overall, with moderate consumption of products containing sodium citrate and adherence to the principles of a keto diet, this additive does not pose a serious health risk.
