Abstract
Description
[Technical Field]
[0001] The present invention relates to a hydrated chocolate. [Background technology]
[0002] In recent years, with the development of mass production technology and distribution networks, high-end confectioneries that were once mainly sold at specialty stores have become easily available for purchase at supermarkets, convenience stores, etc. One example of this is hydrated chocolate, including raw chocolate (see, for example, Patent Document 1).
[0003] Furthermore, in recent years, with growing interest in realizing a sustainable society, attention has been focused on the effective utilization of waste, such as the upcycling of cocoa husk, the outer skin of cocoa beans that is discarded during the chocolate manufacturing process. Cocoa beans, the raw material for chocolate, are separated into cocoa nibs, the edible part, and cocoa husk, the outer skin, during the processing process. Cocoa husk is considered to be the cause of excessive bitterness and unpleasant flavors, and has traditionally been removed and discarded during the chocolate manufacturing process, but in recent years there have been known cases where it has been used as an ingredient in tea (see, for example, Patent Document 2).

[0027] The content of cacao husk in the water-containing chocolate (100% by mass) is preferably 4% to 16% by mass, more preferably 5% to 15% by mass, and even more preferably 14%, 13%, 12%, 11%, or 10% by mass.
[0028] <Method for improving the cocoa flavor of hydrated chocolate> The method for improving the cacao flavor of the water-containing chocolate according to this embodiment is a method for improving the cacao flavor of the water-containing chocolate without causing poor emulsification during the production of the water-containing chocolate by adding cocoa husk. By adding cocoa husk to the water-containing chocolate, poor emulsification during the production can be prevented and the cacao flavor of the water-containing chocolate can be improved, preferably the emulsification stability of the water-containing chocolate over time can be improved, and more preferably the water activity of the water-containing chocolate can be reduced.
[0029] Detailed explanations of the hydrated chocolate and cocoa husk have been given above and will be omitted here.
[0030] <Effects of this embodiment> According to this embodiment, it is possible to provide a water-containing chocolate that does not suffer from poor emulsification during production and has an improved cocoa flavor, and a method for improving the cocoa flavor of water-containing chocolate without causing poor emulsification during production of the water-containing chocolate.
[0031] Furthermore, according to this embodiment, a secondary effect can be obtained in that the stability over time (emulsion stability over time) of the water-containing chocolate can be improved.
[0032] This embodiment also has the secondary effect of reducing the water activity of the hydrated chocolate. This is particularly advantageous in that the water activity can be reduced compared to that of hydrated chocolate produced using the same amount of cocoa powder. This inhibits bacterial growth in the hydrated chocolate, thereby stabilizing its quality. In this embodiment, the water activity of the hydrated chocolate is preferably less than 0.85, more preferably 0.845 or less, and even more preferably 0.843 or less, or 0.841 or less. The lower limit is not particularly limited, but may be, for example, 0.70 or more, 0.75 or more, 0.80 or more, 0.81 or more, or 0.82 or more. [Example]
[0033] The present invention will be described in more detail below using examples and comparative examples, but the technical scope of the present invention is not limited to these.
[0034] <Preparation of cacao husk> Cocoa husk was pulverized using a grinder. The obtained coarsely ground material was added with water and heated to sterilize. The sterilized material obtained was dried and re-ground in a dry grinder to obtain cocoa husk powder. The particle size of the obtained cocoa husk powder was 115.0 μm as the 90% passing diameter when particle size distribution was measured using a laser diffraction / scattering method. The particle size was measured by a dry method using air as a dispersion medium, using a laser diffraction / scattering particle size distribution measuring device ("MT3300EXII" manufactured by Microtrack Bell).
[0035] <Production of hydrated chocolate> A hydrated chocolate was produced using the raw materials shown in Tables 1 and 2 below. Specifically, a tempered chocolate dough was produced using raw materials other than fresh cream. The produced chocolate dough was mixed with fresh cream and emulsified (O / W / O type) to obtain a hydrated chocolate. The cacao husk powder used was the cacao husk powder obtained above.
[0036] [Table 1]
[0037] [Table 2]
[0038] [Table 3]
[0039] <Evaluation of hydrated chocolate> The produced hydrated chocolates were evaluated for cocoa flavor and stability over time by two trained panelists according to the following evaluation criteria. The evaluation results (consensus of all panelists through discussion) are shown in Table 3. The time required for emulsification (×: no emulsification) and the measurement results of the water activity of the produced hydrated chocolates are also shown in Table 3. The emulsification time was measured by stirring once per second, and every 5 seconds, a tester was used to check whether or not the chocolate had emulsified (power was turned off when an O / W / O emulsion was achieved). The water activity was measured using a water activity measuring device (product name: AQUALAB TDL 2, manufactured by Meter Japan). Specifically, 10 g of hydrated chocolate was placed in a dedicated dish in the water activity measuring device, which was kept at 23°C, and the water activity was measured when the sample reached 23°C.
[0040] (Evaluation items and criteria) [Cacao flavor] (A piece of hydrated chocolate was placed in the mouth, chewed three times, and then licked, and the cacao flavor was evaluated.) ×: Almost no cocoa flavor △: A slight cocoa flavor can be felt 〇: You can feel the cocoa flavor ◎: Rich cocoa flavor
[0041] [Stability over time] (The produced hydrated chocolate was hardened at 18°C for one day, then stored at 28°C for two days, and then evaluated by passing an electric current through a tester.) ×: Emulsification is broken △: Emulsification is slightly broken 〇: The emulsion is not broken
[0042] When Example 1 and Comparative Example 1 are compared, they are equally excellent in terms of stability over time and emulsification time, but Example 1 is superior in terms of cocoa flavor and water activity. At a water activity of around 0.85, even a difference of 0.001 can make a big difference in the growth of food poisoning bacteria, and a difference of 0.09 can be considered a very large difference. When Example 2 and Comparative Example 2 are compared, they are equally excellent in terms of cocoa flavor, but Example 2 is superior in terms of stability over time, emulsification time, and water activity. Similarly, when Example 3 and Comparative Example 3 are compared, they are equally excellent in terms of cocoa flavor, but Example 3 is superior in terms of stability over time, emulsification time, and water activity. The overall moisture content of the water-containing chocolates of Examples 1 to 3 and Comparative Examples 1 to 3 differs slightly due to the difference in moisture content between the cocoa husk and the cocoa powder. However, since the difference is so slight that it has almost no effect on the water activity of the water-containing chocolate, it is believed that the addition of cocoa husk is the main factor behind the decrease in water activity.
