Stabilizer

Stabilizers are a group of food ingredients used to help maintain the physical properties of food products. They prevent ingredients from separating, keep textures consistent, and extend shelf life by preventing changes in appearance or feel. Stabilizers can come from various natural sources, like plants or seaweeds, or be produced synthetically.

Manufacturers add stabilizers to prevent ingredients from settling or separating, such as in salad dressings, or to maintain a smooth, uniform texture in products like ice cream, yogurt, and sauces. They are also used to prevent crystallization in frozen foods and to improve the overall mouthfeel of many processed foods.

"Stabilizer" is a general term for a functional class of ingredients, not a single substance. Each specific stabilizer used in food is subject to individual regulation by the FDA, either as a food additive that requires approval or as a substance generally recognized as safe (GRAS). The safety of individual stabilizers is evaluated based on available scientific evidence. For example, some common stabilizers like gums (e.g., xanthan gum, guar gum) have been evaluated by international bodies like JECFA, which typically establishes an acceptable daily intake (ADI) or determines that an ADI is "not specified" due to very low toxicity.
