Title: Takehiro Unno: Innovator in Crystalline Tagatose Production
Introduction
Takehiro Unno is a notable inventor based in Fuji, Japan. He has made significant contributions to the field of food science and technology, particularly in the production of crystalline tagatose. With a total of 5 patents to his name, Unno's work has garnered attention for its innovative approaches and practical applications.
Latest Patents
One of Unno's latest patents is a method for producing crystalline tagatose. This invention provides a method for producing tagatose crystals from an aqueous system without the use of organic solvents. In this method, seed crystals of tagatose are added to a solution with a tagatose purity of at least 70% and a solid content concentration of 60 to 98 mass %. The crystallization process involves stirring and cooling the solution while maintaining a degree of supersaturation of tagatose at 1.25 or lower. The solution is preferred to be free of organic solvents, and the tagatose crystals formed are separated by centrifugation or filtration and dried to obtain the final product.
Another significant patent by Unno involves cyclodextrin glucanotransferase and its method of manufacture. This enzyme acts on starch, dextrin, amylopectin, and amylose to primarily produce γ-cyclodextrin, with smaller quantities of β- and α-cyclodextrin. The enzyme exhibits optimal activity at a pH of 10.5-11.0 and a temperature of about 60°C, demonstrating remarkable stability and residual activity even after treatment at elevated temperatures.
