Fat/oil composition containing fine particle composite and method for producing same

A composition comprising:

• a fine particle composite comprising insoluble dietary fibers;
• and
• a fat/oil,
• wherein the fine particle composite comprises agglomerated fine particles comprising the insoluble dietary fibers,
• wherein the composition satisfies the following (1) to (8):
• (1) the composition comprises an edible part and an inedible part of a food material comprising insoluble dietary fibers, wherein a dry weight proportion of the inedible part to a sum of the edible part and the inedible part is 1% or more and 80% or less,
• (2) the composition comprises the insoluble dietary fiber at a content of 0.1 mass % or more,
• (3) a content of the fine particles is 2 mass % or more and 98 mass % or less,
• (4) a total fat/oil content is 10 mass % or more and 98 mass % or less,
• (5) the composition comprises water at a content of less than 20 mass %,
• (6) a modal diameter after ultrasonication is 0.3 mm or more and 200 mm or less,
• (7) a ratio of a specific surface area per unit volume after ultrasonication [m2/mL] to a minimum particle size after ultrasonication [μm] is 0.1 or more,
• (8) a ratio of a specific surface area per unit volume before ultrasonication [m2/mL] to the specific surface area per unit volume after ultrasonication [m2/mL] is 0.01 or more and 0.99 or less, and
• wherein the insoluble dietary fibers are derived from the edible part and the inedible part of one kind of the food material comprising insoluble dietary fibers.
