Alginates are often used as thickeners in emulsions, such as salad dressings and mayonnaise, where they prevent the separation of water from oil. They are very useful in frozen fish products in oil, where they prevent oxidation by forming a film around the product and simultaneously prevent bacterial contamination.
They are used in the production of whipped cream, sauces, and canned products.
In the dairy industry, they are successfully used in the production of chocolate milk, fruit yogurts, and thermally treated cheeses.
