This invention relates to a combined confectionery that includes a combination of a baked confectionery with a chocolate, wherein whitening on a baked confectionery part and blooming on a chocolate part, the whitening and blooming occurring with the lapse of time, are prevented.
A baked confectionery such as biscuits, cookies is utilized for not only the baked confectionery itself, but also a combined confectionery configured such that the baked confectionery is combined with a chocolate. The combined confectionery can be produced by, for example, combining a baked confectionery preliminarily baked and a chocolate preliminarily prepared, or spreading the preliminarily prepared chocolate on the baked confectionery dough or filling in the baked confectionery dough with the preliminarily prepared chocolate so as to bake.
It is known that with regard to a combined confectionery comprised of a combination of a baked confectionery and a chocolate, oil-and-fats included in the baked confectionery and the chocolate migrates into each other during distribution and storage (the oil-and-fat included in the baked confectionery migrates into the chocolate and the oil-and-fat included in the chocolate migrates into the baked confectionery). If the migration of the oil-and-fat included in the baked confectionery and the chocolate of the combined confectionery occurs, “whitening” may be caused in which white powder spot appears on a surface of a baked confectionery part of the combined confectionery, and blooming may be caused on chocolate part of the combined confectionery. As mentioned above, if the baked confectionery part of the combined confectionery causes the whitening and the chocolate part causes the blooming, the commodity value of combined confectionery would be lost.
As the suppressing means of the whitening on the baked confectionery part and the blooming on the chocolate part of the combined confectionery in association with the migration of the oil-and-fat included in the baked confectionery and the chocolate of the combined confectionery, it has been proposed to use an oil-and-fat having a specific SFC for a kneading oil-and-fat blended in the baked confectionery (Patent Literature 1), and to use a specific triglyceride (Patent Literature 2). In addition, it has been proposed to use a chocolate including a special type triacylglycerol that has a saturated fatty acid having a carbon number of 20 to 24 as the constituent fatty acid (Patent Literature 3).
However, any of the kneading oil-and-fats blended in the baked confectionery described in Patent Literature 1 and Patent Literature 2 is an oil-and-fat using a partially hydrogenated oil-and-fat including a trans fatty acid in a large amount, thus it is not corresponding to the needs in the times from the view point of the trans fatty acid problem in recent years. In addition, the triacylglycerol described in Patent Literature 3 is expensive, and additionally has a high melting point, thus it has a weak point that meltability in the mouth of chocolate is damaged. In addition, the above-mentioned trials that improve either the baked confectionery or the chocolate have been unsatisfactory in effectiveness.
Then, a technique or method for providing a combined confectionery has been desired, the combined confectionery being more effective and corresponding to the needs in the times, and being capable of preventing whitening on a baked confectionery part and blooming on a chocolate part.

According to the formulation of the raw material oil-and-fat shown in Tables 1 and 2, each oil-and-fat of Examples 1 to 8 for baked confectionery was prepared, 0.6 parts by mass of the emulsifier was added with respect to 99.4 parts by mass of each oil-and-fat, so as to be dissolved and mixed, and then quick cooling and kneading for plasticization was applied thereto by using Onlator, thereby each oil-and-fat composition (shortening) of Examples 1 to 8 was prepared.
A cookie of the formulation shown in Table 3 was prepared by using each shortening of Examples 1 to 8. Namely, sugar was added to each shortening softened, and mixed well. Then whole egg was added in several times to avoid separation. Shifted flour was added to the mixture to prepared dough. After refrigerating the dough at rest, the dough was expanded by a roller so as to be a thickness of 3 mm, and was cut out with circular cutter having a diameter of 3 cm, and was baked in an oven for 8 minutes, at 180 degrees C. of upper fire and at 160 degrees C. of lower fire, thereby each cookie of Examples 1 to 8 was obtained.
<Preparation I of Chocolate>
According to the formulation shown in Table 4, chocolates of Examples 9 to 10 were prepared. Namely, by the blending ratio shown in the Table 4, oil-and-fats and the other raw materials were mixed with each other. Subsequently, according to the conventional method, refining, conching and tempering were carried out, so that the chocolates of Examples 9 to 10 formed in a shape of 36.5 mm (length) by 38 mm (width) by 3 mm (thickness) were obtained.
<Evaluation I of Combined Confectionery>
Combined confectioneries of Examples 11 to 26 were obtained from each cookie (baked confectionery) of Examples 1 to 8 and each chocolate of Examples 9 to 10, by placing the cookie on the chocolate formed in a plate-like shape and adhering the bottom surface of the cookie to the chocolate. The combined confectioneries obtained were preserved at 30 degrees C. for 2 weeks. Whitening on the cookie and blooming on the chocolate in the combined confectioneries after the completion of the preservation were evaluated by the following evaluation criteria by visual observation. The evaluation of whitening and blooming was judged as good in case of a double circle mark (⊚) or a single circle mark (∘). The evaluation result was shown in Tables 5 to 8. Examples 11 to 18, 23, 24 and 26 are Comparative Examples.
<Evaluation Criteria of Whitening>
⊚: Whitening was not found.
∘: Whitening was not found but color unevenness was slightly found in surface.
Δ: Whitening was partly found.
x: Whitening was found.
<Evaluation Criteria of Blooming>
⊚: Blooming was not found.
∘: Blooming was not found but gloss was slightly lost.
Δ: Blooming was partly found.
x: Blooming was found.
<Preparation II of Baked Confectionery>
According to the formulation of the raw material oil-and-fat shown in Table 9, each oil-and-fat of Examples 27 to 30 for baked confectionery was prepared.
Each oil-and-fat of Examples 27 to 30 for baked confectionery was heated and melted, and 10 mass % thereof with respect to biscuits were spray-coated on the biscuits, so that the biscuits of Examples 27 to 30 were obtained. The biscuits were produced according to the formulation shown in Table 10. Namely, wheat flour, sugar, salt, and flavor were mixed with each other, and further commercially available shortening was added thereto, so as to be ground together. Combine and dissolve water, whole egg, and sodium bicarbonate, and add the liquid to the mixture, then mix well to obtain a soft dough. After refrigerating the dough at rest, the dough was expanded by a roller so as to be a thickness of 3 mm, and was cut out with a circular cutter having a diameter of 3 cm, and was baked in an oven for 8 minutes, at 200 degrees C. of upper fire and at 180 degrees C. of lower fire, thereby the biscuits of Examples 27 to 30 were obtained.
<Preparation II of Chocolate>
According to the formulation shown in Table 11, chocolates of Examples 31 to 32 were prepared. Namely, by the blending ratio shown in the Table 11, oil-and-fats and the other raw materials were mixed with each other. Subsequently, according to the conventional method, refining, conching and tempering (seeding) were carried out, so that the chocolates of Examples 31 to 32 formed in a shape of 36.5 mm (length) by 38 mm (width) by 3 mm (thickness) were obtained.
<Evaluation II of Combined Confectionery>
Combined confectioneries of Examples 33 to 40 were obtained from each biscuit (baked confectionery) of Examples 27 to 30 and each chocolate of Examples 31 to 32, by placing the biscuit on the chocolate formed in a plate-like shape and adhering the bottom surface of the biscuit to the chocolate. The combined confectioneries obtained were preserved by repeating 3 cycles, as one cycle being at 37 degrees C. for 12 hours and at 20 degrees C. for 12 hours. Whitening on the cookie and blooming on the chocolate in the combined confectioneries after the completion of the preservation were evaluated by the following evaluation criteria by visual observation. The evaluation of whitening and blooming was judged as good in case of a double circle mark (⊚) or a single circle mark (∘). The evaluation result was shown in Tables 12 to 13. Examples 33 to 36, 39 and 40 are Comparative Examples.
