Temperature-stable liquid-core capsules
Novel products are composed of a liquid core (fluid) coated by a hydrocolloid membrane with different properties, sizes and compositions can mimic grapes, different berries, caviar, and the like. The membrane can be tailored to different thicknesses and thermal stabilities. While their use in foods is obvious, enzymes and cells can also be included within the droplet and used for continuous fermentation, possible transplantation, slow release and other biotechnological processes.
