Process for crosslinking gelatin and for incorporation a material therein.

摘要

A method of crosslinking gelatin comprises making a composition which comprises a gelatin, a sugar, a water-soluble salt of a carboxylic acid, water, and an additional ingredient, particularly vitamin A which is to be encapsulated or entrapped within the crosslinked gelatin matrix. The composition is thereafter heated while maintaining the moisture content at a level of at least about 3 weight percent, based on the weight of the composition. A product comprises a gelatin product which is crosslinked to a degree at which it is substantially insoluble upon being placed in water at 100 DEG C for at least 3 minutes.
