Food products containing starch in their composition may show syneresis as an undesired effect and require the addition of gum. Syneresis was not observed during the 28 days of storage of the three studied formulations, demonstrating the positive hygroscopic effect of adding 0.2% xanthan gum. This anionic hydrocolloid interacts with the positive charges on the surface of casein micelles and reinforces the network formed, consequently reducing syneresis and promoting increased stability in the product.
