Title: Production of protein emulsifying agent
Inventor: YOSHIDA TAKAHARU
IPC: A23L27/60
Filed: 1997-09-26
Abstract: PROBLEM TO BE SOLVED: To produce the subject emulsifying agent having a high emulsifying function and having emulsifying activity even in an acidic region by using a grain protein as a substrate, treating the substrate for hydrolysis with a protease for a short time under a strongly acidic condition, adjusting the pH of the treated solution into a specific range and removing the formed insoluble matters. SOLUTION: This emulsifying agent is produced by hydrolyzing a substrate consisting of a grain protein with a protease under a strongly acidic condition of pH of <=2.5 for a short time of <=6 hr, adjusting the pH of the treated solution to 3-5, and removing the formed insoluble matters. Further, a protein derived from a grain such as soybean, wheat, green peas, corn or rice can be used as the grain protein; however, a protein derived from soybean is preferable since it is excellent in emulsifying activity and emulsion stability under acidic condition.

IPC: G02B1/14
Filed: 1990-09-28
Abstract: PURPOSE:To eliminate the unequal color of reflected light by immersing a base material into a liquid compsn. and lowering a liquid level at a specified speed or at continuously changing speeds, then curing the compsn. by heating. CONSTITUTION:After the base material is immersed into the liquid compsn. in a tank provided with an outflow port in the lower part, the liquid level of the liquid compsn. is lowered at the specified speed or at the continuously changing speeds and thereafter, the compsn. is cured by heating. Unequal film thicknesses arise and a uniform antireflection or reflection increasing film is not obtainable if the vertical disturbance of the descending level increases. The control of the descending speed is so executed that the liquid compsn. does not generate the turbulence in this case. The curing by heating is executed by using hot wind, IR rays, etc., at such a temp. at which hydrolysis does not arise. The antireflection or reflection increasing film is free from the unequalness of the reflected light color in this way. The uniform reflected light color is thus obtd.
