Since Dai-Nippon Sugar Mfg. Co. (Predecessor of Ryoto Co.) constructed the first commercial plant with productivity of 1,200 ton/year in 1967, the demand of sucrose esters has increased 15-20% per annum and reached a 1,000 ton/year total in Japan, Asia and Europe. In order to meet demand which is expected to grow, Ryoto completed a new plant capable of producing 3,000 ton/year at the end of 1974. The products are completely solvent-free. The new process developed by Ryoto does not employ dimethylformamide as a solvent which has often caused public discussion about the safety of sucrose esters. The quality of the new products meets the additional requirement of EEC common approval that the total sucrose ester content shall be not less than 90% and the total methanol content (free and combined) shall be not more than 10 mg per kg, and the specifications of FAO/WHO. Sucrose esters are of great promise not only in food fields but also in non-food uses, especially in detergents. Detergents made with sucrose ester, sodium citrate, propylene glycol and ethanol have been expanding the market for food and household kitchen purposes due to edibility, mild washing ability and 100% biodegradation.
