Disclosed are: a fat reduced soymilk having a reduced fat content which is produced by separating a fat from a fat containing soybean efficiently without relying on an organic solvent； and a novel fat rich soybean material. Specifically disclosed are: a fat reduced soybean protein material characterized by containing a protein and a carbohydrate at a total content of 80 wt% or more in terms of dried form content containing a fat (as an extract from a chloroform/methanol mixed solvent) at a content of less than 10 wt% relative to the content of the protein and containing campesterol and stigmasterol (as plant derived sterols) at a total content of 200 mg or more relative to 100 g of a fat； and a soybean emulsion composition characterized by containing a protein at a content of 25 wt% or more in terms of dried form content containing a fat at a content of 100 wt% or more in terms of dried form content relative to the content of the protein in terms of dried form content and having an LCI value of 60% or more.
