Definition & Meaning of "bulking agent"

What is a "bulking agent"?

A bulking agent, also known as a filler or diluent, is a substance added to food or beverages to increase their volume or bulk without significantly affecting their nutritional content or taste. These agents are used to improve the texture, appearance, and mouthfeel of food products, as well as to reduce costs by replacing more expensive ingredients. Bulking agents can be either soluble or insoluble and may contribute to the viscosity or consistency of the final product. Common bulking agents include carbohydrates, proteins, fats, and fiber. Bulking agents are commonly used in a variety of food products, including baked goods, processed meats, sauces, soups, and beverages, to provide texture and volume while maintaining overall quality and functionality. They are regulated by food authorities to ensure they are safe for consumption and used within recommended levels.
