[0004] A vegetable oil powder containing vegetable oil, carbohydrate, 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 predetermined amounts 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).

EXAMPLES

[0055] The present invention will be specifically described below by way of examples, but the present invention is not limited to these in any way.

[0056] (Preparation of oil-in-water emulsified powdered oils A to E) Powdered oils A to E used in the test examples described below were prepared as follows. When making the powdered oil and fat, a solution was prepared by dissolving powdered glucose (manufactured by Toyo Kagaku Co., Ltd.), skimmed milk powder (manufactured by Yotsuba Dairy Products Co., Ltd.), sodium caseinate (manufactured by Tatua Pharmaceuticals), sorbitan fatty acid ester (Poem S-60V, manufactured by Riken Vitamin Co., Ltd.), and lecithin (J Lecithin CL, manufactured by J-Oil Mills Inc.) in warm water (temperature 60 to 80°C) to obtain the composition shown in Table 1 below. The solution prepared above was added to oil (vegetable oil (hardened palm oil, manufactured by Fuji Oil Co., Ltd.: triacylglycerol content 89.9% by mass) adjusted to about 70°C so as to obtain the powdered oil and fat with the composition shown in Table 1 below, followed by mixing and preliminary emulsification. Next, heat sterilization was performed at 70°C for 10 minutes, and then homogenization was performed using a pressure homogenizer to obtain an emulsion. This emulsion was sprayed using a spray dryer in a conventional manner, followed by drying and powderization to obtain oil-in-water emulsified powdered oils and fats (hereinafter sometimes referred to as "powdered oils and fats") A to E.

[0057] [Table 1]

[0058] (Commercially available oil-in-water emulsified powdered oils and fats) In addition, the following commercially available products a to d were prepared as oil-in-water emulsified powdered oils and fats to be used in the test examples described later.

Commercially available product c: Cream Powder CH (manufactured by Asahi Group Foods Co., Ltd.) Commercially available product: Neuract ND-200S-NGM (manufactured by Asahi Group Foods Co., Ltd.)

[0059] <Measurement of emulsion diameter> The emulsion diameter of the oil contained in the oil-in-water emulsified powdered oil was measured as follows. A sample prepared by suspending 1 g of powdered oil in 50 mL of water was used and the particle size was measured using a laser diffraction particle size measuring device (Mastersizer 3000, Malvern Panalytical).

[0060] <Particle size measurement> The average particle size of the above-mentioned oil-in-water emulsified powdered oil was measured as follows. The particle size was measured using a laser diffraction particle size analyzer (Mastersizer 3000, Malvern Panalytical).

[0061] (Preparation of non-emulsified powdered oils and fats) Unemulsified powdered oils 1 to 3 used in the test examples described later were prepared as follows. When preparing the powdered oil, the oil that had been heated and melted (vegetable oil (hardened palm oil, manufactured by Fuji Oil Co., Ltd.: triacylglycerol content 89.9% by mass)) was mixed with dextrin to obtain the composition shown in Table 2 below, thereby obtaining non-emulsified powdered oils 1 to 3.

[0062] [Table 2]

[0063] The emulsion diameters of the various powdered oils and fats mentioned above are summarized in Table 3 below.

[0064] [Table 3]

[0065] (Test Example 1) Using the various powdered oils and fats described above, tablets (Examples 1 to 22, Comparative Examples 1 to 7), which are examples of tablet-type foods, were produced as follows.

[0066] <Tablet manufacturing> Among the ingredients shown in Tables 4 to 11 below, each ingredient other than calcium stearate was mixed in the amount shown in Tables 4 to 11 below. Then, calcium stearate was added in the amount shown in Tables 4 to 11 below, and mixed to obtain each tablet powder. The powder was packed and compressed at a pressure of 4 kN using a tablet press (AUTOTAB-200, manufactured by Ichihashi Seiki Co., Ltd.) to obtain tablets with a diameter of 8 mm, a radius of curvature (R) of 6.5 mm, and a weight of 250 mg per tablet. Details of each component used are as follows: Lactose: SuperTab 14SD (DFE Pharma) Cellulose: Ceolas OD-20F (manufactured by Asahi Kasei Corporation) Calcium stearate: food additive calcium stearate (manufactured by Sakai Chemical Industry Co., Ltd.)

Aspartame: PAL SWEET DIET (manufactured by Ajinomoto Co., Inc.)

[0067] In addition, in Comparative Examples 1 to 3, the fluidity of the powder for tableting was poor, and it was difficult to feed the raw material to the tablet press, so tablets were not produced.

[0068] <Hardness measurement> The hardness of the tablets was measured using a load cell type benchtop hardness tester Portable Checker PC-30 (manufactured by Okada Seiko Co., Ltd.) The results are shown in Tables 4 to 11.

[0069] <Evaluation of tableting suitability> The suitability for tableting was evaluated visually for each of the following items according to the following criteria.
