PROBLEM TO BE SOLVED: To provide a gelling agent for acid thick liquid food, capable of preparing without its passing through a homogenizing process, even acidic thick liquid food with a low pH, such as pH of 3-4, that is smooth gel-like food which is free from causing condensation of proteins and fats.SOLUTION: This gelling agent for acid thick liquid food is constituted of deacylation type gellan gum, glucomannan and/or Cyamoposis Gum used together.COPYRIGHT: (C)2009,JPO&INPIT【課題】pHが3~4といった低pHの酸性濃厚流動食であっても、均質化工程を経ずに、タンパク質や脂質の凝集がない滑らかなゲル状物を調製することが可能な酸性濃厚流動食用ゲル化剤を提供する。【解決手段】酸性濃厚流動食用ゲル化剤として、脱アシル型ジェランガム、グルコマンナン及び/又はグァーガムを併用する。【選択図】図2
