[0001] The present invention relates to a tablet-type food product containing powdered oil and fat, and a method for producing the same.

[0002] Powdered oils and fats are used as ingredients for various foods and beverages or as additives to various foods and beverages.

[0003] To date, for example, powdered oils and fats containing (A) a predetermined glyceride mixture, (B) a predetermined powdered base material, and (C) water in predetermined amounts have been proposed (see, for example, Patent Document 1).

[0004] A vegetable oil powder containing vegetable oil, sugar, and protein or lipophilic modified starch has been proposed (see, for example, Patent Document 2).

[0005] An emulsified powder for tableting has been proposed, which contains a predetermined amount of a solid oil (A) having a predetermined melting point, an emulsifier (B), and a water-soluble dietary fiber (C) having a predetermined viscosity, in which the solid oil (A) is disposed inside and the outside of the solid oil (A) is coated with the water-soluble dietary fiber (C) (see, for example, Patent Document 3).

[0006] As a method for producing soft and smooth tablet candy, a method has been proposed in which an emulsion consisting of a water-soluble organic polymer compound, an emulsifier, and fats and oils is used as a binder (see, for example, Patent Document 4).
