PROBLEM TO BE SOLVED: To provide a concentrated oily food raw material containing a readily hygroscopic raw material that is extremely readily hygroscopic at a high proportion, and hardly changing physical properties such as viscosity or color tone by moisture absorption.SOLUTION: The concentrated oily food raw material suppressing moisture absorption, and the physical properties hardly changed, and has a grain size of not more than 100 μm can be obtained by making the readily hygroscopic raw material and oil content satisfy prescribed relational formulas.COPYRIGHT: (C)2013,JPO&INPIT【課題】本発明の目的は、きわめて吸湿しやすい易吸湿性原料を高い割合で含み、且つ吸湿により粘度や色調などの物性の変化しにくい、濃縮油性食品原料を提供することにある。【解決手段】易吸湿性原料と含油量が所定の関係式を満たすことで、吸湿を抑え、物性の変化しにくい粒度が100μm以下の濃縮油性食品原料が得ることができる。【選択図】図2
