Zusammenfassung:	To realize particles having excellent feel properties with a water-soluble material having excellent biodegradability.SOLUTION: Porphyran particles of the present invention are mainly composed of porphyran, which is a trans-polysaccharide having galactose molecules as structural units. The average particle size is less than 0.5 to 20 μm and the protein content is less than 100 ppm. In addition, the method for producing porphyran particles of the present invention comprises: preparing a dispersion of porphyran having a protein content of less than 100 ppm; and spray-drying and granulating the dispersion to obtain porphyran particle powders.SELECTED DRAWING: Figure 1 【課題】優れた感触特性を持つ粒子を、生分解性に優れた水溶性の材料で実現する。【解決手段】本発明のポルフィラン粒子は、ガラクトース分子を構成単位とするトランス型の多糖類であるポルフィランで主に構成されている。平均粒子径が０．５～２０μｍ未満、蛋白質の含有量が１００ｐｐｍ未満である。また、本発明のポルフィラン粒子の製造方法は、蛋白質の含有量が１００ｐｐｍ未満のポルフィランの分散液を調製する工程と、分散液を噴霧乾燥して造粒し、ポルフィラン粒子の粉末を得る工程を備えている。【選択図】図１
