Firming

Firming agents are substances that help foods maintain their firm texture. They are often minerals or salts, such as calcium chloride or calcium sulfate, which can interact with natural compounds in fruits and vegetables to create a firmer structure.

Manufacturers use firming agents to prevent foods like canned fruits and vegetables, pickles, and jams from becoming soft or mushy during processing and storage. They help maintain the desired texture and appearance of these products.

Firming agents like calcium chloride and calcium sulfate are generally recognized as safe (GRAS) by the FDA when used as intended. These minerals are naturally present in the body and in many foods. International bodies like JECFA have evaluated these substances. Evidence does not suggest adverse health effects from typical dietary intake.
