Abstract
A method of crosslinking protein comprises making a composition which comprises a protein, a sugar, a water-soluble salt of a carboxylic acid, water, and an additional ingredient which is to be encapsulated or entrapped within the crosslinked protein 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 protein which is crosslinked to degree at which it is substantially insoluble upon being placed in water at 100.degree. C. for at least 3 minutes, a sugar, a water-soluble salt of a carboxylic acid, water, and an additional ingredient which is encapsulated or entrapped within the crosslinked protein matrix.
