Coat your berries while they are still frozen with our TIC Pretested® Colloid 911 to prevent weeping, especially in muffins or other baked goods. As the berries thaw the water and gum form a protective glaze. To use, sprinkle 1.5-3.0%, based on the weight of the berries. You can see from the photo that the berries retain their shape and your baked good retains its color. To save your own berries order a sample to see for yourself from http://ticgums.com/Product.asp?ID=41
