Acidity regulators, also known as acidulants, are a type of food additive commonly used to regulate the acidity or alkalinity of foods and beverages.

Polifar's acidity regulators include various types of acids such as lactic acid, malic acid, fumaric acid, citric acid, tartaric acid, phosphoric acid, and sodium citrate. These acids are used in a wide range of food and beverage products to provide a sour or acidic taste, to control the pH level, and to act as preservatives.

Lactic acid is commonly found in dairy products and sourdough bread, while malic acid is often used in sour candies and fruit-flavored products. Fumaric acid is a naturally occurring organic acid found in various plants and fruits. It is commonly used to enhance the sourness and tartness of foods and beverages. Citric acid, derived from citrus fruits, is widely used in soft drinks, candies, and other processed foods. Malic acid is a naturally occurring organic compound found in various fruits, particularly in apples. It is often used as a food additive to give a sour or tart taste to foods and beverages. Tartaric acid, derived from grapes, is used in baking powders and certain beverages. Phosphoric acid is commonly found in cola drinks, and sodium citrate is used as an emulsifier and preservative in various food products.

These acidity regulators play a crucial role in maintaining the desired taste, texture, and shelf life of a wide variety of food and beverage products.
