PROBLEM TO BE SOLVED: To provide a food additive for environmental cleaning also serving as a medicine for intestinal disorders and a feed, capable of forming an intestinal flora in which spore-bearing effective bacteria easily work by allowing such compounded ingredients as chromoprotein that hardly dissolve with gastric acids and that can make feeds for intestinal bacteria to reach the intestines.SOLUTION: The food additive for environmental cleaning also serving as the medicine for intestinal disorders and the feed contain coral power and/or pearlite as main ingredients, and compounded ingredients are adsorbed in the coral powder by compounding a photocatalyst coated with a silk component, organic germanium and chromoprotein.COPYRIGHT: (C)2012,JPO&INPIT【課題】胃酸でも溶けずらく、色素たんぱく質のような腸内細菌のえさにもなる配合成分が腸にまで届くようにして、有胞子性有用菌が働きやすい腸内細菌叢を形成することができる環境浄化用食品添加物兼整腸剤及び飼料を提供する。【解決手段】サンゴパウダーおよび/またはパーライトを主成分とし、シルク成分でコーティングした光触媒、有機ゲルマニウムおよび色素タンパク質を配合することにより、サンゴパウダーに配合成分を吸着させたことを特徴とする環境浄化用食品添加物兼整腸剤及び飼料。【選択図】なし
