Description

chocolate

The present invention relates to chocolate that is easy to temper.

Chocolate is a confectionery made from cacao beans that has excellent flavor and mouthfeel. In particular, temper type chocolate (such as chocolate containing only cocoa butter contained in cacao beans as an oil and fat) is known as a general chocolate. This temper type chocolate is usually obtained by tempering a melted chocolate dough obtained from a chocolate raw material and then cooling and solidifying the chocolate dough. Tempering is an operation for generating crystal nuclei (seed crystals) of stable crystals in the melted chocolate dough. Since cocoa butter can have various crystal structures, tempering is necessary to solidify the cocoa butter in the chocolate dough as stable crystals. As a specific example of tempering, there is known an operation in which the temperature of a chocolate dough melted at 40 to 50 ° C. is lowered to about 27 to 28 ° C. and then heated again to about 29 to 31 ° C.

If the amount of seed crystals produced by tempering is appropriate, the solidification rate of the chocolate dough during cooling is increased. Moreover, sufficient volume shrinkage occurs when the chocolate dough solidifies. Furthermore, the solidified chocolate is peeled off from the mold well (that is, the mold release is good). Occurrence of fat bloom (a phenomenon in which white fat crystals are generated on the chocolate surface; hereinafter referred to as “bloom”) is also suppressed. The obtained chocolate not only has excellent gloss, but also has excellent bloom resistance during storage. Such an appropriate tempering state is called "proper temper".

On the other hand, if the amount of seed crystals produced by tempering is too small, bloom often occurs. Moreover, the bloom tolerance during preservation | save of the obtained chocolate falls. Therefore, bloom may occur in the chocolate being stored in a short period of time. Such a tempering state is called “under temper”. If the amount of seed crystals produced by tempering is too large, the texture of the resulting chocolate will be rough. Therefore, bloom resistance during storage of chocolate may be reduced. Such a tempering state is called “overtempering”. In the production of chocolate, management of the tempering state is important in order to avoid undertemper and overtemper.

As a method for managing the tempering state, a method for obtaining a temper index using a temper meter has been developed. The temper meter is a machine that patterns the amount of heat generated by crystallization of fats and oils in chocolate dough by cooling over time. The temper index obtained based on the measurement data of the temper meter can be used as an index representing the tempering state. For example, a temper index of 1 to 3 is an under temper and represents a state where tempering is insufficient. When the temper index is 4 to 6, it is a proper temper and represents a good tempering state. The cases 7 to 9 are overtempered, indicating that the amount of seed crystals is excessive and the viscosity is increased. By using the temper meter, the tempering state can be managed with a numerical value (temper index).

By the way, it is known that the bloom resistance of chocolate is improved by including special triacylglycerol in the fats and oils of chocolate. For example, JP-A-2-138937 discloses an anti-blooming agent containing mono-U di-S triglyceride (SSU) as an active ingredient. Japanese Patent Laid-Open No. 5-31190 discloses a triglyceride in which one of the constituent fatty acids is a saturated fatty acid (B) having 12 or less carbon atoms and the remaining two fatty acids are saturated fatty acids (A) having 16 or more carbon atoms. An oil and fat graining inhibitor (A2B) is described.

When the triacylglycerol as described above is contained in a small amount in the fats and oils of chocolate, the bloom resistance of chocolate is improved. However, there is a problem that the amount of the seed crystal is not stable even if tempering is performed, such that the temper index is a proper temper and becomes an under temper.

The chocolate in the present invention uses edible fats and sugars as main ingredients. A cacao component (cocoa mass, cocoa powder, etc.), a dairy product, a fragrance, an emulsifier, etc. are added to the main raw material as needed. This chocolate is manufactured through all or part of the chocolate manufacturing steps (mixing step, atomization step, scouring step, molding step, cooling step, etc.).

Subsequently, the ester interchange was performed by transesterification with a 1,3-position specific lipase. Fatty acid ethyl was distilled from the transesterification mixture, and the distillation residue was subjected to solvent fractionation to obtain (SOS-1). The SOS content of (SOS-1) was 66.7% by mass.

[Preparation of chocolate 1]
According to the formulations shown in Tables 1 and 2, the chocolates of Comparative Examples 1 to 5 and Examples 1 to 5 were mixed, atomized and refined according to a conventional method. Then, 1.0 mass% of the seed agent containing the stable crystal | crystallization of SOS was added with respect to the fats and oils contained in chocolate dough. As a result, seeded melted chocolate dough was obtained. The temper index of each melted chocolate dough was measured. The results are shown in Tables 1 and 2.

[Broom resistance test]
The seeded melted chocolate doughs of Comparative Examples 1 and 2 and Examples 1, 4, and 5 were cooled and solidified. The solidified chocolate was die-cut and subjected to a test. The gloss of each chocolate after die cutting was evaluated according to the following criteria. Moreover, the flavor of each chocolate of Comparative Examples 1 and 2 and Examples 1, 4, and 5 held at 20 ° C. for 1 week after die cutting was evaluated according to the following criteria. Further, each of the chocolates of Comparative Examples 1 and 2 and Examples 1, 4 and 5 held at 20 ° C. for 1 week was held at a temperature cycle of 12 ° C. for 12 hours and 20 ° C. for 12 hours. Hung. Bloom observation of the chocolate surface was performed every 7 cycles and evaluated according to the following criteria. The results are shown in Table 3.

(Evaluation criteria for gloss)
A: Excellent gloss B: Normal C: No gloss

(Flavor evaluation standard)
A: The cocoa flavor is strongly felt. B: The cocoa flavor is felt slightly strongly.
C: Normally

(Evaluation criteria for bloom observation)
-: Good without blooming-+: Slight blooming occurred +: Blooming occurred and defective

[Hard butter]
In the blending of the chocolates of Examples 1 to 5, the fats and oils containing SOS-1 and fats and oils containing L2M and LM2 in advance, or the fats and oils containing SOS-1 and L2M, LM2 and MMM were mixed in advance. Fats and oils can be used as hard butter having an excellent function of improving bloom resistance. Table 4 shows the composition of the hard butter in Examples 1 to 5 assuming that a premixed hard butter was used.
