Abstract

Certain cultured plant cell gums, including those produced in suspension culture of plant cells of plants of the family Aizoaceae are described. Plant cell gums of plants of the genus Mesembryanthemum are specifically provided. Also described are the methods of using these cultured plant cell gums in the manufacture of food products, pharmaceuticals and veterinary products, cosmetics and other industrial products, such as paper, adhesive, ink, textiles, paint, ceramics, explosives, cleaning agents or detergents, products for firefighting, agricultural chemicals including pesticides and fungicides, for oil and gas production, and in photography, lithography, and other industries are described. Food, pharmaceutical, veterinary, industrial and cosmetic compositions containing certain cultured plant cell gums are also described. Plant cell gums can be employed as substitutes for plant exudate and extract gums and other known emulsifying, viscosifying and gelling agents.
