Description

[Technical field]

[0001] The present disclosure relates to a method of extracting tea and to frozen tea products. [Background technology]

[0002] Drinking tea has been a culture in Japan and around the world since ancient times, and tea is made in a variety of ways, such as pouring hot water into a teapot containing tea leaves, placing tea leaves in a teabag in a teacup and pouring hot or cold water over them, or putting powdered tea leaves in a teacup and dissolving them in hot or cold water.

[0003] It is also known that the bitterness, astringency, and sweetness of tea vary greatly depending on the temperature of the water used to extract the tea, and while tea made with hot water produces an astringent taste, sweet tea can be extracted by using water at room temperature or water that has just melted from ice. Patent Document 1 discloses an iced tea extractor used in an iced tea extraction method in which tea liquid is extracted over a sufficient period of time using ice dripping.

[0004] [Patent Document 1] Utility Model Registration No. 3134428 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in these technologies, it takes a very long time, up to overnight, to extract tea using water from freshly melted ice, so there was a need to be able to start preparing the tea and then start drinking it while enjoying a meal or conversation with family or guests.

[0006] An object of the present disclosure is to make it possible to extract tea in a shorter time than conventional tea extraction methods while using water that has just melted ice. [Means for solving the problem]

[0007] The method for extracting tea disclosed herein includes the steps of preparing frozen tea leaves having a size of 1.5 mesh pass or less, and preparing ice having a size of 1.5 mesh pass or less, and extracting tea by combining the tea leaves and the ice at room temperature in a ratio of 25 to 50 parts by weight of the ice to 1 part by weight of the total tea leaves. Effect of the Invention

[0008] According to the present disclosure, tea can be brewed in less than two hours using freshly melted ice water. [Brief description of the drawings]

[0009] [Figure 1] FIG. 1 is a graph showing the size of tea leaves and ice and the time at which the tea can be drunk. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] [Description of the embodiments of the present disclosure] First, embodiments of the present disclosure will be listed and described. [1] A method of extracting tea according to the present disclosure includes the steps of preparing frozen tea leaves having a size of 1.5 mesh pass or less, and preparing ice having a size of 1.5 mesh pass or less, and extracting tea by combining the tea leaves and the ice at room temperature in a ratio of 25 to 50 parts by weight of the total ice to 1 part by weight of the total tea leaves.

[0011] This allows tea to be brewed in less than two hours using water from freshly melted ice. More specifically, instead of starting preparations for brewing tea the night before and drinking it the next morning, for example, when enjoying dinner at a restaurant, tea leaves and ice are served when you sit down, and you can enjoy dinner with family or friends while watching the ice melt and the tea slowly brew, and enjoy freshly brewed iced tea while enjoying dinner or at the end of the meal.

[0012] [2] A method of extracting tea according to the present disclosure includes the steps of preparing frozen tea leaves having a size of 1.5 mesh pass or less, and preparing ice having a size of 4 mesh pass or less, and extracting tea by combining the tea leaves and the ice at room temperature in a ratio of 50 to 75 parts by weight of the total ice to 1 part by weight of the total tea leaves.

[0015] This reduces the amount of tea leaves relative to the ice, and even when using relatively large ice cubes, tea can be extracted in less than two hours using water that has just melted the ice.

[0016] [4] A method of extracting tea according to the present disclosure includes the steps of preparing frozen tea leaves having a size of no greater than 5 mesh pass and preparing ice having a size of no greater than 2.5 mesh pass, and extracting tea by combining the tea leaves and the ice at room temperature in a ratio of 75 to 150 parts by weight of the total ice to 1 part by weight of the total tea leaves.

[0017] This allows tea to be brewed in less than two hours using water that has just melted ice, even with a further reduction in the amount of tea leaves relative to the ice.

[0018] [5] A method of extracting tea according to the present disclosure includes the steps of preparing frozen tea leaves having a size of 10 mesh pass or less, and preparing ice having a size of 1.5 mesh pass or less, and extracting tea by combining the tea leaves and the ice at room temperature in a ratio of 75 to 150 parts by weight of the total ice to 1 part by weight of the total tea leaves.

[0019] This allows the amount of tea leaves relative to the ice to be further reduced, and even when using relatively large ice cubes, tea can be extracted in less than two hours using water that has just melted the ice.

[0020] [6] The frozen tea body of the present disclosure comprises frozen tea leaves having a size of 1.5 mesh pass or less, and ice having a size of 1.5 mesh pass or less, and the tea leaves and ice are combined in a ratio of 25 to 50 parts by weight of the total ice to 1 part by weight of the total tea leaves.

[0021] This allows tea leaves and ice to be packed in packs of a specified size and ratio, stored in freezers at convenience stores and supermarkets, and then sold, making it possible for tea to be easily extracted at home in less than two hours using water from freshly melted ice.

[0022] [7] The frozen tea body of the present disclosure comprises frozen tea leaves having a size of 1.5 mesh pass or less and ice having a size of 4 mesh pass or less, and the tea leaves and ice are combined in a ratio of 50 to 75 parts by weight of the total ice to 1 part by weight of the total tea leaves.

[0023] As a result, even if the amount of tea leaves relative to ice is reduced, tea leaves and ice packs of a specified size and ratio can be stored and displayed in freezers at convenience stores, supermarkets, etc., and tea can be easily extracted at home in less than two hours using water from freshly melted ice.

[0024] [8] The method of extracting tea according to the present disclosure comprises frozen tea leaves having a size of 5 mesh pass or less and ice having a size of 1.5 mesh pass or less, the tea leaves and the ice being mixed in a ratio of 50 to 75 parts by weight of the total ice to 1 part by weight of the total tea leaves.

[0025] This allows the amount of tea leaves relative to the ice to be reduced, and even if relatively large ice is used, tea leaves and ice packs of a specified size and ratio can be stored and displayed in freezers at convenience stores, supermarkets, etc., for sale, making it possible to easily extract tea at home in less than two hours using water from freshly melted ice.

[0026] [9] The method of extracting tea according to the present disclosure comprises frozen tea leaves having a size of a 5 mesh pass or less and ice having a size of a 2.5 mesh pass or less, and mixing the tea leaves and ice in a ratio of 75 to 150 parts by weight of the total ice to 1 part by weight of the total tea leaves.

[0027] As a result, even if the amount of tea leaves relative to ice is further reduced, tea can be extracted easily at home in less than two hours using water from freshly melted ice by storing and displaying packs of tea leaves and ice in a specified size and ratio in freezers at convenience stores and supermarkets.

[0028]

[10] The method of extracting tea according to the present disclosure comprises frozen tea leaves having a size of 10 mesh pass or less and ice having a size of 1.5 mesh pass or less, and mixing the tea leaves and ice in a ratio of 75 to 150 parts by weight of the total ice to 1 part by weight of the total tea leaves.

[0029] This allows the amount of tea leaves relative to the ice to be further reduced, and even if relatively large ice is used, tea leaves and ice packed in a specified size and ratio can be stored and displayed in freezers at convenience stores, supermarkets, etc., and sold, making it possible to easily extract tea at home in less than two hours using water from freshly melted ice.

[0030]

[11] The method of extracting tea according to the present disclosure is the method of extracting tea according to the above [1], in which the mesh size of the mesh for sifting the tea leaves is A1 (mm) and the mesh size of the mesh for sifting the ice is B1 (mm), and the maximum time T1 (min) until the tea can be drunk is adjusted by adjusting A1 and B1. T1=42.6×1.027^B1×A1^(0.27-0.0031×B1) The tea is extracted while making predictions.

[0031] This allows tea to be extracted in less than two hours using water from freshly melted ice while predicting the maximum time at which drinking can begin for a certain range of tea leaf to ice weight ratios, thereby enabling the timing of serving tea to be managed in restaurants and homes.

[0032]

[12] The method of extracting tea according to the present disclosure is the method of [2] or [3] above, in which, when the mesh size of the mesh for sifting the tea leaves is A2 (mm) and the mesh size of the mesh for sifting the ice is B2 (mm), the maximum time T2 (min) for starting drinking can be adjusted by adjusting A2 and B2. T2=43.7×1.04^B2×A2^(0.27-0.0013×B2) The tea is extracted while making predictions.

[0033] This makes it possible to predict the maximum time that tea can be consumed when the weight ratio of tea leaves to ice is reduced to a certain range, while brewing tea in less than two hours using water from freshly melted ice, thereby enabling the timing of serving tea to be managed in restaurants and homes.

[0034]

[13] The method of extracting tea according to the present disclosure is the method of [4] or [5] above, in which, when the mesh size of the mesh for sifting the tea leaves is A3 (mm) and the mesh size of the mesh for sifting the ice is B3 (mm), the maximum time T3 (min) for starting drinking can be adjusted by adjusting A3 and B3. T3=53.7×1.03^B3×A3^(0.27-0.0053×B3) The tea is extracted while making predictions.

[0035] This allows tea to be extracted in less than two hours using water from freshly melted ice while predicting the maximum time at which drinking can begin when the amount of tea leaves relative to ice is further reduced to keep the weight ratio of tea leaves to ice within a certain range, thereby enabling the timing of serving tea to be managed in restaurants and homes.

[0036] [Details of the embodiment of the present disclosure] Specific examples of the tea extraction method and frozen tea product of the present disclosure will be described below with reference to the drawings. Note that the present disclosure is not limited to these examples, but is defined by the claims, and is intended to include all modifications within the meaning and scope of the claims.

[0037] (1 tea leaf) The tea leaves 1 can be of various types that are generally available on the market. The tea leaves 1 are frozen at a temperature of 18°C ​​or less, cut into various sizes, and mixed with ice 2 (described below) at room temperature to extract tea. Room temperature refers to a temperature between 15°C and 30°C. The extracted tea can be consumed or used in cooking.

[0038] The size of the tea leaves 1 is defined using a mesh pass. The mesh (sieve) used in this embodiment and the mesh opening dimensions are shown in Table 1 below. The size of the tea leaves 1 can be adjusted by any method, such as rolling or cutting, and the size of the tea leaves 1 may be adjusted before freezing or after freezing.

[0039] [Table 1]

[0040] (Ice 2) Ice 2 can be any type of potable water, and is frozen at -18°C or below, cut into various sizes, and mixed with tea leaves 1 at room temperature to extract tea.

[0041] The size of the ice 2 is defined using a mesh pass, similar to that of the tea leaves 1. The mesh (sieve) and mesh opening size used in this embodiment are as shown in Table 1 above. The size of the ice 2 can be adjusted by any method, such as pouring water into a mold of the desired size to form the ice, or crushing or shaving it from a larger piece of ice.

[0042] (Preliminary experiment) First, factors such as the size of tea leaves 1 and ice 2, type of tea leaves, and room temperature were changed to identify factors and trends that affect the drinkable start time. The smaller the tea leaves 1, the shorter the drinkable start time, and like tea leaves 1, the smaller the ice 2, the shorter the drinkable start time. There was no significant difference in the drinkable start time even when the freezing temperature of tea leaves 1 and ice 2 was lower than -18°C. At a room temperature of 30°C, the drinkable start time was shorter compared to a room temperature of 15°C. The drinkable start time was longer when the ratio of the total weight of ice 2 to the total weight of tea leaves 1 was high. There was no significant difference in the drinkable start time depending on the type of tea leaves 1.

[0043] (Experimental conditions) Based on the results of the above preliminary experiment, the experimental conditions were set as follows. Three types of tea leaves were used: α from a major manufacturer, β from another manufacturer, and γ from yet another manufacturer. The size of tea leaves 1 was set to five levels: 1.5 mesh pass or less, 5 mesh pass or less, 10 mesh pass or less, 100 mesh pass or less, and 400 mesh pass or less. The size of ice 2 was set to five levels: 1.5 mesh pass or less, 2.5 mesh pass or less, 3.5 mesh pass or less, 4 mesh pass or less, and 5 mesh pass or less. The ratio of ice 2 to tea leaves 1 was set to three levels: 25 to 50, 50 to 75, and 75 to 150 percent of the total weight of ice 2 per total weight of tea leaves 1. The temperature for freezing tea leaves 1 and ice 2 was minus 20°C. The room temperature at which tea leaves 1 and ice 2 were combined was 15°C.

[0044] (Evaluation Results) The drinkable start time was evaluated by a sensory taste test by three panelists. The test was conducted three times under the same conditions (N=3), and the time at which the three panelists evaluated the tea as being sufficiently drinkable and edible (not too weak in taste) was measured, and the longest time was determined as the drinkable start time. The total weight of ice 2 to total weight of tea leaves 1 was set to 25 to 50, 50 to 75, and 75 to 150, and the results are shown in Tables 2 to 4 below, respectively. If the drinkable start time exceeded 120 minutes, the experiment was terminated at that point, and the time was recorded as "over 120."

[0045] [Table 2]

[0046] [Table 3]

[0047] [Table 4] TIFF2025071741000006.tif11170

[0048] (Maximum drinkable start time) Figure 1 plots the results of the drinkable start time under the conditions in Table 2 (when the total weight of ice 2 to the total weight of tea leaves 1 is set to 25 to 50) on a double logarithmic graph. As shown in Figure 1, as mentioned above, the drinkable start time became shorter the smaller the tea leaves 1, the smaller the ice 2, and the lower the ratio of the total weight of ice 2 to the total weight of tea leaves 1. Furthermore, it was found that the relationship between the drinkable start time and tea leaves 1 in the double logarithmic graph could be approximated by a linear function. Based on this result, the maximum value T1 of the drinkable start time under the conditions in Table 2 (when the total weight of ice 2 to the total weight of tea leaves 1 is 25 to 50) is, when the mesh size of the mesh for sifting tea leaves 1 is A1 (mm) and the mesh size of the mesh for sifting ice 2 is B1 (mm), T1=42.6×1.027^B1×A1^(0.27-0.0031×B1) We found that this can be calculated using the following approximate formula (the "^" in the formula represents a power): Similarly, the maximum value T2 of the drinkable start time under the conditions in Table 3 (when the total weight of ice 2 to the total weight of tea leaves 1 is 50 to 75) is given by the following when the mesh size of the mesh for sifting the tea leaves is A2 (mm) and the mesh size of the mesh for sifting the ice is B2 (mm): T2=43.7×1.04^B2×A2^(0.27-0.0013×B2) We found that this can be calculated using the following approximate formula (the "^" in the formula represents a power): Similarly, the maximum value T3 of the drinkable start time under the conditions in Table 4 (when the total weight of ice 2 to the total weight of tea leaves 1 is 75 to 150) is given by the following when the mesh size of the mesh for sifting the tea leaves is A3 (mm) and the mesh size of the mesh for sifting the ice is B3 (mm): T3=53.7×1.03^B3×A3^(0.27-0.0053×B3) We found that this can be calculated using the following approximate formula (the "^" in the formula represents a power): This makes it possible to predict the maximum time (in minutes) that tea can be drunk, making it possible to manage the timing of tea serving in restaurants and homes.

[0049] (Brown frozen body 3) Frozen tea 3 refers to a pack of tea leaves 1 of a specified size or less and ice 2 of a specified size or less mixed in a specified ratio. Frozen tea 3 can be stored and displayed in freezers at convenience stores, supermarkets, etc., and sold, allowing tea to be easily extracted at home in less than two hours using water from freshly melted ice. In addition, by using the above approximate formula for T1, T2, and T3 for frozen tea 3 and indicating the drinkable start time on the package of the frozen tea, it is possible to provide a frozen tea 3 that allows the desired drinkable start time to be predicted and managed.
