The present invention is a chocolate containing fat and sugar and the content of triacylglycerol having a total of 22 to 46 carbon atoms of the constituent fatty acid residue in the fat is 25 to 80% by mass, It is chocolate which has the heat-resistant shape retention more than melting | fusing point of the said fats and oils. The present invention further relates to a chocolate having a triacylglycerol content of 20 to 70% by mass in which the total number of carbon atoms of the constituent fatty acid residues in the oil and fat is 32 to 40.

Description

  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.

  Therefore, development of a chocolate dough in which an increase in viscosity is suppressed even when a small amount of water is added to the chocolate dough, and development of a chocolate having heat resistance even when a low melting point fat is used have been desired.

  The subject of this invention is providing the chocolate which has soft food texture by using the fats and oils which have low melting | fusing point, and has heat resistance, and its manufacturing method.

  The present inventors have intensively studied to solve the above problems. As a result, when liquid oil is blended in 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.

  The MLCT may be prepared by ester synthesis, similar to MCT. MLCT may also be prepared by transesterifying a mixed fat of MCT and the non-lauric fat. The MLCT used in the present invention is preferably a mixture in which MCT and non-lauric oil / fat are mixed at a mass ratio of 10:90 to 90:10 (more preferably 20:80 to 80:20). It is a transesterified oil of fat. The method for transesterification is not particularly limited. For example, the transesterification may be performed by a commonly performed method such as chemical transesterification using sodium methoxide as a catalyst or enzymatic transesterification using a lipase preparation as a catalyst.

  The milk fat is oil derived from milk, and its processed product is also included. More specifically, butter, butter oil or fractionated oil thereof, fermented fraction oil, fermented butter, fermented butter oil or fractionated oil thereof, and the like can be mentioned.

In addition, 25 to 80% by mass of triacylglycerol having a total of 22 to 46 carbon atoms of the constituent fatty acid residues can be contained in the fat or oil of chocolate. Thereby, the raise of the dough viscosity by the water addition to the chocolate dough demonstrated later can be suppressed.

  In order to obtain a soft texture, the chocolate of the present invention may contain a liquid oil. Content of the liquid oil which occupies for the fats and oils contained in the chocolate of this invention becomes like this. Preferably it is 10-45 mass%, More preferably, it is 15-40 mass%, More preferably, it is 20-40 mass%.

Moreover, triacylglycerol of fats and oils can be measured according to, for example, a gas chromatographic method (JAOCS, vol 70, 11, 1111-1114 (1993). Also, SFC (%) of fats and oils is measured by IUPAC method 2.150 Solid Content. It can be measured 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. You may adjust the compounding quantity of the emulsifier which has a viscosity reducing effect so that the ratio to chocolate may be 0.2-1 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. Content of the sucrose contained in the chocolate of this invention becomes like this. Preferably it is 32-54 mass%, More preferably, it is 34-50 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.

  The chocolate of the present invention preferably contains 1 to 20% by mass of lactose as one of saccharides. By containing lactose, the strength of the sugar skeleton of chocolate can be increased. Lactose is preferably crystalline and is preferably formulated as crystals.

Content of the lactose contained in the chocolate of this invention becomes like this. More preferably, it is 2-18 mass%, More preferably, it is 3-16 mass%. Whether lactose is crystalline or not can be confirmed by powder X-ray diffraction.

  The chocolate of this invention may mix | blend the raw material generally used for chocolate other than fats and oils and saccharides. 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 milk powder used for the chocolate of the present invention is also preferably produced by spray drying such as a spray drier like the above-illustrated milk powder. 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. Content of the water of the chocolate of this invention becomes like this. Preferably it is 0.8-3 mass%, More preferably, it is 0.9-2.5 mass%, More preferably, it is 1.0-2.0 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 process, the heating in the conching process 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 includes 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, it is preferably 0.5 to 2 parts by mass, and 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.

  The temperature of the water and water-containing material used in the step of adding water is preferably about the same as the temperature of the melted chocolate to which water and water-containing material are 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 conditions for cooling and solidification 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, a tempering process or a seeding process 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 product 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 seeding process is a process of generating stable crystal nuclei in a melted chocolate using a seeding agent that functions as a stable crystal nuclei instead of a tempering process. 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.

  In the case of 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.

  The chocolate after cooling and solidification may be further subjected to an “aging process” for “heat retention treatment”. In the heat retention treatment, the chocolate after cooling and solidification is preferably 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.

  Since the chocolate which concerns on preferable embodiment of this invention has a low melting | fusing point and soft food texture, and has favorable heat resistance, it can be used for the use of all the chocolates. 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 which concerns on preferable embodiment of this invention has a sugar skeleton, even if it bakes, it is hard to collapse, and baking chocolate can be manufactured easily. For example, when baking in 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, an example explains the present invention. However, the present invention is not limited by these examples.

Fructose-glucose liquid sugar (water content: 25% by mass) was added to and dispersed in 100% by mass of the melted chocolate at 44 ° C. in the chocolate with “added” water 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. Thereby, the chocolate of Comparative Examples 1-4 and Examples 1-4 was 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, 5 expert panelists comprehensively evaluated the biting and squeezing of each chocolate of Comparative Examples 1 to 4 and Examples 1 to 4 prepared above. Moreover, each chocolate of Comparative Examples 1-4 and Examples 1-4 was left still in a 40 degreeC thermostat, and shape loss (shape retention) 12 hours after 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.
