Abstract: The paper studied spraying Arabic gum, CMC－Na, β-CD on soybean milkpowder’s surface for the purpose of improving soybean milk powder’s mobility and disperse property The results are as follows:spraying single Arabicgum 2.0g/100g soybean milk powder, or CMC－Na 0. 369g/100g soybean milk powder, or β-CD1. 0g/100g soybean milk powder on soybean milk powder’s surface can prevent dissolution agglomeration and possess better dampproof function, When using Arabuic gum, CMC-Na, β-CD together, spraying Arabic gum 1.0g/100g soybean milk powder, CMC-Na0.246g/100g soybean milk powder, β-CD1.0g/100g soybean milk powder can notonly prevent dissolution agglomeration, but dampproof function is better than spraying single Arabic gum’s or CMC-Na’s of β-CD’s.Keywords:Soybean Milk Powder Dissolution Properties Arabic gum β-CD CMC-Na
