Sponges
Hydrocolloids are combined and processed in many different patented ways to produce sponges with no nutritional value that are dry, with different degrees of dryness, porosity, taste, composition and color. Hydrocolloid sponges are compressible and can absorb liquids. The sponges are excellent matrices for the inclusion of proteins, carbohydrates, vitamins, microorganisms and many other compounds. They can serve as the basis for high- or low-calorie foods. In their compressed form, they can be an excellent potential food source in the air and space industry. The sponges can also be specifically designed to target a wide range of markets. With their high liquid-absorbing properties and high degree of compressibility, the sponges can be adapted for use as medicinal bandages, biodegradable diapers and hygienic pads.
