Patent number: 5624500Abstract: A syrup of natural carob sugars having 55-75% sucrose, 7-15% fructose, 7-16% glucose, 0.5-3% other sugars, 4-14% cyclitols and 0.5-2% organic and inorganic impurities. Sugars are extracted from carob pulp and the juice thus obtained is subjected to chromatographic separation to separate the sugars from the non-sugars. The product obtained may be used in applications similar to those of other sugars.Type: GrantFiled: March 29, 1995Date of Patent: April 29, 1997Assignee: Compania General del Algarrobo de Espana, S.A.Inventor: Carlos Sanjuan Diaz

Patent number: 5601076Abstract: The present invention is a new spheroidal polycrystallite product and a process for making the same. In the present invention amorphous sugar is transformed to crystalline sugar by hydrating rather than dehydrating sugar. The product of the present invention is unique in shape, size, and possesses a high degree of uniformity.Type: GrantFiled: June 5, 1995Date of Patent: February 11, 1997Assignee: Fuisz Technologies Ltd.Inventors: Gerald Battist, Garry L. Myers, Richard C. Fuisz
