Description

Baked chocolates and method for producing the same

The present invention relates to chocolates for baking use, baked chocolates using the same, and a method for producing the same.

Baking chocolates brings about a new flavor and texture, and also provides heat resistance. For example, the chocolate dough surface is moisture-absorbed and baked (Patent Document 1), and at least a portion is sprinkled with sugar (Patent Document 2), and the chocolate dough containing the starchy raw material and water is baked (Patent Document 3). ), Etc. are exemplified.

However, since these undergo a baking process, it is not easy to control the fat and oil crystals, and as the amount of tempering type fat and oil such as cocoa butter increases, there is a problem of occurrence of bloom and graining. Therefore, non-tempering type fats and oils have mainly been used in baked chocolates. However, in terms of flavor and melting in the mouth, there has been a strong market demand for baked chocolates containing a large amount of tempering type fats and oils.

The present invention has an object to provide a baked chocolate in which a certain amount of tempering type fats and oils are contained and which has a good flavor and melt in the mouth and in which the occurrence of bloom is suppressed, and a method for producing the same.

As a result of intensive studies, the present inventors use chocolates containing 13 to 22% by weight of SOS-type triglycerides and blending normal temperature liquid oils and fats to adjust the fat composition in chocolates to a specific range of SFC. Thus, it was found that baked chocolates in which the occurrence of bloom was suppressed were obtained, and the present invention was completed.

According to the present invention, it is possible to provide baked chocolates that have a good flavor texture and heat resistance while suppressing the occurrence of bloom.

(SOS type triglyceride)
In the present invention, SOS type triglyceride (hereinafter abbreviated as SOS) means S (saturated fatty acid having 16 or more carbon atoms) at the 1st and 3rd positions, and O (oleic acid which is a monounsaturated fatty acid having 18 carbon atoms) at the 2nd position. Is a symmetric triacylglyceride in which is bound, and is the main component of a tempering type fat such as cocoa butter.

(Chocolate)
The chocolates in the present invention are not subject to regulations ("Fair competition regulations on the display of chocolates") or legal restrictions, and various chocolates and fat processed foods and chocolates using animal and vegetable oils and fats other than cocoa butter, chocolate Includes products. Raw materials such as cacao mass, cocoa butter, cocoa, edible oils and fats, saccharides, milk powder, emulsifiers, and fragrances are appropriately blended, and chocolates are prepared by a conventional method.
The chocolate of the present invention is characterized by containing SOS in an amount of 13 to 22% by weight, preferably 15 to 22% by weight. If it is less than 13% by weight, it may be difficult to obtain a baked chocolate with good melting in the mouth, and if it exceeds 22% by weight, bloom may easily occur. When SOS is blended as derived from cocoa butter, the SOS content in cocoa butter is about 85% by weight, which corresponds to a cocoa butter content of 15 to 25% by weight in chocolates. The cocoa butter content here refers to the amount derived from cocoa mass (cocoa butter content: about 55% by weight) and cocoa (cocoa butter content: about 11-22% by weight) in addition to the blended amount as cocoa butter. Say total.
In the present invention, by adding 7 to 20% by weight of a fat or oil having a melting point of 20 ° C. or lower, that is, liquid at normal temperature, chocolates having a composition satisfying SFC described later can be easily obtained.

(SFC)
The chocolates of the present invention have a total fat content (including cocoa butter in cocoa mass and milk fat in milk powder) of 40 to 65% at 10 ° C and 20 to 50% at 20 ° C. 10 to 40% at 25 ° C, 1 to 8% at 30 ° C, preferably 40 to 50% at 10 ° C, 22 to 40% at 20 ° C, 12 to 25% at 25 ° C, 1 to 30% at 30 ° C 6%, more preferably 45-50% at 10 ° C, 26-40% at 20 ° C, 12-25% at 25 ° C, and 2-6% at 30 ° C. If it is too high, the bloom suppressing effect may be small, and if it is too low, it is too soft, that is, the shape-retaining property is inferior. The SFC in the present invention is obtained by completely thawing the sample oil obtained from chocolate by hexane extraction, and then aging at 20 ° C. for 40 hours in accordance with IUPAC.2 150 “SOLID CONTENT DETERMINATION IN FATS BY NMR”. Use the measured value.

(Baking)
Examples of the method for obtaining the baked chocolate of the present invention include a method in which the temperature of the chocolate is adjusted, molded into an arbitrary shape by die cutting, squeezing out, wire cutting and the like and then baked in an oven, a burner or the like. Examples of the temperature adjustment here include a method of heating and dissolving completely using a hot water bath at around 50 ° C., and a method of semi-dissolving at about 30 ° C. or less. In addition, flours such as wheat flour, starches and processed starches, nuts, dried fruits and the like may be added to the chocolates as appropriate and baked. It can also be baked in combination with bread and baked confectionery as appropriate by methods such as placing, sandwiching, or interspersing molded chocolates.

(BOB)
In the chocolates of the present invention, BOB (1,3-dibenoyl-2-oleylglyceride) is 1.0 to 10.0% by weight, more preferably 2.0 to 10.0% by weight, and still more preferably 3.0 to 10.0%, based on fats and oils in the chocolates. By blending by weight%, the occurrence of bloom after firing can be more effectively suppressed. If the blending amount is more than 10% by weight, the dissolution in the mouth may worsen. Moreover, in order to perform work | work more efficiently, BOB containing fats and oils can also be mix | blended as fats and oils for chocolates. As an example, it can be obtained by transesterifying high oleic sunflower oil and ethyl behenate with 1,3-position specific lipase, distilling off the ethyl ester, and then purifying the high melting point fraction obtained by solvent fractionation. And a method using an oil having a BOB content of 68%.

(Acetylated sucrose fatty acid ester)
The chocolates of the present invention contain acetylated sucrose fatty acid ester in an amount of 0.2.% Or more, more preferably 0.4% or more, so that the occurrence of bloom after baking is further effectively suppressed. Specifically, use of product name: DK ester F-A10E (Daiichi Kogyo Seiyaku) etc. can be illustrated. In the present invention, a bloom suppressing effect can be obtained by blending either one of the aforementioned BOB and acetylated sucrose fatty acid ester, but a combined bloom inhibitory effect can be exhibited synergistically.

(moisture)
In the present invention, 0.1 to 5.0% by weight, preferably 0.2 to 4.0% by weight, and more preferably 0.4 to 2.0% by weight of water is added to and mixed with the chocolate dough before baking. And moderate shape retention during firing can be imparted. If the moisture is less than the lower limit, the effect of the present invention may not be exhibited. If the upper limit is exceeded, the baked chocolates may sag, or the storage stability during distribution may be adversely affected.
Specifically, there is a method in which moisture is added to and mixed with chocolate dough having a fluidity state by adjusting the temperature, and then appropriately shaped and used for the baking step. Here, the water can be blended as water or a composition containing water. Specific examples include liquor, liquid sugar, fruit juice, and oil-in-water emulsions. In that case, it is desirable that the water content is 0.1 to 5.0% by weight with respect to the chocolate dough.

(Tempering)
In this invention, generation | occurrence | production of bloom can be suppressed more effectively by baking chocolate dough after a tempering process. Specifically, there is exemplified a method in which a chocolate dough that has been heated and dissolved is subjected to a tempering treatment by a conventional method such as temperature adjustment or addition of a seed agent, and then subjected to a baking step. Further, the tempered chocolate can be temperature-controlled at about 30 ° C. or less and held and used in a semi-dissolved state.
