Abstract
A method for the retention of a fluid encapsulated in small spherical membranes or inside tubular filamentous membranes, these membranes being a fluid-permeable gel and which comprises the addition of an aqueous solution of a first alginate compound sodium to an aqueous solution of a second compound of a water-soluble calcium salt, with which said first and said second compound react producing a gel coating membrane permeable to water vapor.
