Anti-freezing agents, also known as cryoprotectants, are substances used to prevent the formation of ice crystals in frozen food products. These agents help maintain the texture, taste, and overall quality of food during freezing and thawing processes. They are especially important in preserving the integrity of delicate foods like ice cream, fruits, and seafood.Commonly used in frozen desserts and fruit preserves to lower the freezing point and inhibit ice crystal formation.
