METHOD FOR PRODUCING SILK FINE PARTICLE SOLUTION AND SILK FINE PARTICLE POWDER AND MATERIAL CONTAINING SILK FINE PARTICLE

摘要

PROBLEM TO BE SOLVED: To provide a method for producing an odorless silk fine particle solution and silk fine particle powder from a silk fiber as a raw material and to obtain a material such as a food, a cosmetic and a fiber using the obtained silk fine particle.;SOLUTION: The odorless silk fine particle solution is obtained through a scouring process for subjecting a silk fiber to fixed scouring treatment and removing sericins attached to the silk fiber, a grinding process for mechanically grinding the obtained silk fiber into powder, a rubbing process for rubbing the obtained silk powder with roast salt and a process for predeterminedly desalting the obtained mixture. The silk fine particle powder is obtained by spray-drying or freeze-drying the silk fine particle solution. Since the solution and the fine particle powder are odorless, they are each favorably useful as an additive for a cosmetic, a food, etc., and a coating agent for a fiber.;COPYRIGHT: (C)2006,JPO&NCIPI
