Description

chocolate

The present invention relates to a heat-resistant chocolate and a method for producing the same.

Examples of methods for imparting heat resistance to chocolate include, for example, a method of adding fats and oils having a high melting point to chocolate, a method of increasing the solid content of chocolate (reducing oil content), and mixing a small amount of water with chocolate dough. A method for forming a sugar skeleton is mentioned. However, by blending fats and oils having a high melting point, the mouthfeel of chocolate is remarkably deteriorated. By increasing the solid content of the chocolate, the mouthfeel of the chocolate is impaired. On the other hand, the formation of the sugar skeleton inside the chocolate can impart heat resistance to the chocolate without damaging the mouth and mouthfeel. And even if environmental temperature becomes more than melting | fusing point of the fats and oils contained in chocolate, chocolate can maintain a shape. Therefore, by using fats and oils having a low melting point, a soft texture can be imparted to the chocolate and at the same time heat resistance can be realized. However, mixing a small amount of water into the chocolate dough causes an increase in viscosity. Therefore, productivity is reduced.

In order to suppress the increase in the viscosity of the chocolate dough, a method of mixing glycerol or sorbitol instead of water (for example, US Pat. No. 6,488,879), a method of mixing a water-in-oil emulsion (for example, US Pat. No. 6,165,540) or the like is known. . However, even with these methods, the increase in viscosity is still large, making industrial production difficult.

US64888879 US6165540

Therefore, it has been desired to develop a chocolate dough that suppresses the increase in viscosity even if a small amount of water is added to the chocolate dough, and to develop a chocolate that has heat resistance even if a low melting point oil is used.

An object of the present invention is to provide a chocolate having a soft texture and heat resistance by using an oil having a low melting point, and a method for producing the chocolate.

The present inventors have conducted intensive research to solve the above problems. As a result, when liquid oil is added to the fats and oils contained in chocolate to lower the melting point, the increase in viscosity due to the addition of a small amount of water becomes significant, and the fats and oils have a total carbon number of 22 to 46. It has been found that when a specific amount of a certain triacylglycerol is added, an increase in viscosity can be suppressed. As a result, the present invention has been completed.

That is, the present invention provides the following.

In addition, 25 to 80% by mass of triacylglycerol in which the total number of carbon atoms of the constituent fatty acid residues is 22 to 46 can be contained in the fats and oils of chocolate. Thereby, the raise of the dough viscosity by the water addition to the chocolate dough demonstrated later can be suppressed.

In the present invention, the constituent fatty acids of the oil and fat can be measured according to, for example, AOCS Ce1f-96. Oil triacylglycerol can be measured, for example, according to the gas chromatographic method (JAOCS, vol 70, 11, 1111-1114 (1993). SFC (%) of oil is measured by IUPAC method 2.150 Solid Content. It can be determined according to determination in Fats by NMR.

Since the continuous phase of chocolate is fat, the fat content of chocolate greatly affects the viscosity of the chocolate dough. As the fat content in the chocolate is higher, the viscosity is lower, and the influence of the increase in viscosity caused by the addition of water can be reduced. However, the higher the fat content in chocolate, the lower the sugar ratio and the brittle sugar skeleton structure, and the heat resistance of the manufactured chocolate may decrease. On the other hand, when the fat / oil content is 30% by mass or less, the viscosity of the chocolate dough increases, and the influence of the increase in viscosity due to the addition of water also increases. Therefore, the handling property at the time of chocolate manufacture may fall. Such reduction in handling property can be suppressed to some extent by blending an emulsifier (lecithin, polyglycerin condensed ricinoleate (PGPR), etc.) having a viscosity-reducing action with chocolate. The blending amount of the emulsifier having a viscosity-reducing action may be adjusted so that the proportion in the chocolate is 0.2 to 1% by mass. The emulsifier having a thinning action is preferably lecithin and PGPR. Lecithin and PGPR are preferably used in a mass ratio of 4: 6 to 8: 2.

As the sucrose, it is appropriate to use powdered sugar obtained by powdering granulated sugar, which is a sucrose crystal. The content of sucrose contained in the chocolate of the present invention is preferably 32 to 54% by mass, more preferably 34 to 50% by mass. When the content of sucrose contained in the chocolate of the present invention is within the above range, a sugar skeleton is easily formed in the chocolate.

For example, cacao mass, cocoa powder, dairy products (milk solids, etc.), emulsifiers, fragrances, pigments, etc., starches, gums, thermocoagulable proteins, various powders such as strawberry powder and matcha powder, Various food ingredients and various food additives can be mentioned.

The chocolate of the present invention preferably contains milk powder. The milk powder used in the present invention is not particularly limited as long as it is a milk-derived powder. Examples include whole milk powder, skim milk powder, whey powder, cream powder, buttermilk powder. One or more kinds of powdered milk can be selected and used. In particular, whole milk powder, skim milk powder, and whey powder are preferably included, and more preferably whole milk powder and skim milk powder are included.

The powdered milk content of the chocolate of the present invention is preferably 4 to 32% by mass, more preferably 8 to 28% by mass, and further preferably 12 to 24% by mass. When content of the milk powder contained in the chocolate of this invention exists in the said range, chocolate has favorable flavor and shape retention property.

The chocolate of the present invention easily forms a sugar skeleton by containing a small amount of water. However, as will be described later, when a small amount of water is added to the melted chocolate, the viscosity of the chocolate dough significantly increases. The water content of the chocolate of the present invention is preferably 0.8 to 3% by mass, more preferably 0.9 to 2.5% by mass, and still more preferably 1.0 to 2.0% by mass. It is.

The chocolate of the present invention can be produced by mixing raw materials such as fats and sugars and milk powder, atomization by roll refining, etc., and conching treatment as necessary according to a conventional method. When performing the conching treatment, the heating in the conching treatment is preferably performed at 40 to 60 ° C. so as not to impair the flavor of the chocolate. In addition, in the manufacturing method of this invention, a process and a process are used as the same meaning.

In the method for producing chocolate of the present invention, in order to adjust the moisture (water content) of chocolate, a water-containing material having water as a raw material or a material having high hygroscopicity may be used. Moreover, manufacture of the chocolate in a melt state may have the process (the following [process of adding water]) of adding and disperse | distributing water.

The production of the chocolate of the present invention preferably has a step of adding and dispersing a small amount of water in advance in order to form a sugar skeleton. Hereinafter, an example of a method for forming a sugar skeleton will be described. The production of chocolate having a sugar skeleton preferably has a step of adding and dispersing water (a step of adding water) to chocolate in a melt state (chocolate dough). In addition, a melt state means the state by which the fats and oils in chocolate were melted.

The temperature of the chocolate in the melt state in the step of adding water is preferably 30 to 60 ° C., more preferably 35 to 50 ° C., and further preferably 35 to 45 ° C. When the temperature of the chocolate in the melt state in the step of adding water is within the above range, water can be added and dispersed without impairing the flavor of the chocolate. The amount of water to be added may be appropriately set so that the water content of the chocolate is 0.8 to 3% by mass. As a standard, the amount is preferably 0.5 to 2 parts by mass, more preferably 0.5 to 1.5 parts by mass with respect to 100 parts by mass of the chocolate in the melt state. In addition, the water content of chocolate can be measured according to a conventional method using a normal pressure drying loss method or a Karl Fischer moisture meter.

The water added in the step of adding water may be only water, or may be a composition containing components other than water together with water (hereinafter, such a composition is referred to as “water-containing material”). Good. Even if the amount of water added in the step of adding water is the same, the rate of increase in the viscosity of the melted chocolate can change depending on the components added together with the water. Specifically, when only water or a water-containing material having a high water content (fruit juice, milk, etc.) is added, the viscosity of chocolate rapidly increases. On the other hand, when a water-containing material such as sugar solution or protein solution is added, the viscosity of chocolate increases relatively slowly. When the viscosity is rapidly increased, water cannot be sufficiently dispersed in the melted chocolate. Therefore, the water added in the step of adding water is particularly preferably a water-containing material such as a sugar solution or a protein solution.

Examples of the sugar liquid include solutions such as reduced starch syrup, fructose glucose liquid sugar, and sorbitol liquid containing sugar and water such as fructose, glucose, sucrose, maltose, and oligosaccharide. Examples of the protein solution include egg white meringue, concentrated milk, and fresh cream containing protein and water. The content of water contained in the sugar solution or protein solution is preferably 10 to 90% by mass, more preferably 10 to 50% by mass, based on the entire solution. In the step of adding water, when water is added in the form of a water-containing material, the addition amount may be added so that the amount of water relative to the melted chocolate falls within the above range.

It is preferable that the temperature of the water or water-containing material used in the step of adding water is approximately the same as the temperature of the melted chocolate to which water or water-containing material is added. By doing so, the temperature of the melted chocolate is kept constant, and water and water-containing material are easily dispersed uniformly. After adding water to the melted chocolate, the water may be uniformly dispersed in the chocolate by stirring or the like.

The melted chocolate that has undergone the step of adding water may be cooled and solidified. By this step, solid chocolate can be efficiently produced from the melt state.

The method for cooling and solidifying the chocolate of the present invention is not particularly limited. What is necessary is just to select suitably according to chocolate products, such as a molding chocolate and the covering chocolate to foodstuffs. The melted chocolate can be cooled and solidified by, for example, spraying cold air in a cooling tunnel (cooling tunnel) or contacting with a cooling plate.

The cooling and solidification conditions are not particularly limited as long as the melted chocolate is solidified. For example, the cooling temperature is preferably 0 to 20 ° C., more preferably 0 to 10 ° C. The cooling time is preferably 5 to 90 minutes, more preferably 10 to 60 minutes.

When the chocolate is a temper type chocolate, tempering treatment or seeding treatment may be performed either before or after the step of adding water.

The tempering treatment is an operation for generating stable crystal nuclei in chocolate in a melt state. Specifically, for example, it is known as an operation of lowering the temperature of chocolate melted at 40 to 50 ° C. to about 27 to 28 ° C. and then heating it again to about 29 to 31 ° C. The tempering treatment is preferably performed before the step of adding water.

The above seeding treatment is a treatment for producing stable crystal nuclei in a melted chocolate using a seeding agent that functions as a crystal nucleus of stable crystals instead of the tempering treatment. A seeding process is performed in order to solidify the fats and oils in chocolate as a V-type stable crystal similarly to a tempering process.

When performing the seeding process, the order of the process of adding the seeding process and water may be first. Moreover, you may perform simultaneously the process of adding a seeding agent and adding water. That is, the seeding agent and water may be simultaneously added to the melted chocolate.

”Aging process” that “heat-treats” may be applied to the chocolate after cooling and solidification. In the heat treatment, the chocolate after cooling and solidification is preferably kept at 16 to 28 ° C., more preferably 18 to 24 ° C., preferably 6 hours or more, more preferably 12 to 480 hours, still more preferably 24 to 360 hours. It is processing to do. By carrying out the heat retaining treatment, the sugar skeleton in the chocolate can be made stronger.

The chocolate according to a preferred embodiment of the present invention has a low melting point and a soft texture, and has good heat resistance, so that it can be used for all chocolate applications. For example, it can be eaten as it is as a lump or cut chocolate lump. In addition, it can be used for bakery foods such as breads, cakes, confectionery, baked goods, donuts, and shoe confectionery. That is, the chocolate of the present invention can be used by die cutting, cutting, whipping, etc. as a coating material, a filling material, or a chocolate chip to be mixed into a dough of a composite bakery food.

Moreover, since the chocolate according to a preferred embodiment of the present invention has a sugar skeleton, it does not easily collapse even when baked, and a baked chocolate can be easily manufactured. For example, when baked in an oven, the chocolate of the present invention is preferably baked at 110 to 240 ° C., more preferably 120 to 200 ° C., preferably 1 to 11 minutes, more preferably 2 to 5 minutes.

Next, the present invention will be described with reference to examples. However, the present invention is not limited by these examples.

[Preparation of chocolate dough]
The formulations of Comparative Examples 1 to 4 and Examples 1 to 4 were in accordance with Tables 1 and 2. A melted chocolate was obtained by mixing, atomizing, and scouring by a conventional method. And the viscosity of chocolate dough was measured in the state of 44 degreeC. Fructose-glucose liquid sugar (water content: 25% by mass) was added to and dispersed in 100 parts by mass of the melted chocolate at 44 ° C. in chocolate with water added in the table. . Then, it fully stirred for 10 minutes and measured the viscosity of chocolate dough. Thereafter, the melted chocolate was cooled and solidified at 10 ° C. and allowed to stand at 20 ° C. for 14 days. As a result, the chocolates of Comparative Examples 1 to 4 and Examples 1 to 4 were obtained. The water content of each chocolate was measured by a normal pressure drying method. Moreover, fats and oils were extracted from each chocolate using hexane, and SFC and melting | fusing point of this fats and oils were measured. Tables 1 and 2 show the measurement results of the viscosity, moisture, and SFC and melting point of the fats and oils contained in the chocolate dough.

[Evaluation of chocolate 1]
According to the following criteria, five expert panelists comprehensively evaluated the biting and squeezing of each of the chocolates of Comparative Examples 1 to 4 and Examples 1 to 4 prepared above. In addition, each chocolate of Comparative Examples 1 to 4 and Examples 1 to 4 was allowed to stand in a constant temperature bath at 40 ° C., and the shape loss (shape retention) after 12 hours was confirmed. The evaluation results are shown in Tables 1 and 2.

(Biting out)
◎: Biting is very soft ○: Biting is soft △: Normal ▲: Biting is slightly hard ×: Biting is hard

(Spoken)
◎: The mouth is sharp and good ○: The mouth is good △: Normal ▲: The mouth is slightly bad ×: The mouth is bad

(Shape retention)
◎: The original shape is retained. ○: The original shape is almost retained.
▲: The original shape is slightly broken ×: The original shape is broken so as not to remain

[Evaluation of chocolate 2]
The chocolates of Comparative Example 3 and Example 3 prepared above were baked in an oven at 200 ° C. for 2 minutes. The chocolate of Comparative Example 3 melted the corners and was severely baked, but the chocolate of Example 3 maintained its shape well.

[Evaluation of chocolate 3]
The chocolates of Comparative Example 3 and Example 3 prepared above were kneaded for 60 seconds using a Hobart mixer (low speed: beater), then placed in a squeeze bag and squeezed out onto pie dough. After that, it was further wrapped in puff pastry. The obtained composite pie dough was cut in half vertically and baked at 200 ° C. for 15 minutes in a state where the wrapped chocolate was visible. As a result, the chocolate of Comparative Example 3 caused sag, but the chocolate of Example 3 was neatly stored in the pie in the same state as before baking.

[Evaluation of chocolate 4]
The chocolates of Comparative Example 3 and Example 3 prepared above were whipped using a Hobart mixer (medium speed: whipper) for 15 minutes to obtain a chocolate cream. Compared with the cream using the chocolate of Comparative Example 3, the cream using the chocolate of Example 3 had a good mouthfeel and the taste of chocolate was good.
