Description

Technical Field

[0001] The present disclosure relates to a method for extracting tea and a frozen tea product.

Background Art

[0002] Since ancient times, there has been a culture of drinking tea in various parts of the world including Japan. Tea is made in various ways, such as pouring hot water into a teapot with tea leaves, putting tea leaves in a tea bag into a cup and pouring water or hot water, or putting powdered tea leaves into a cup and dissolving them with water or hot water.

[0003] Also, it is known that bitterness, astringency, and sweetness vary greatly depending on the temperature of the water used for tea extraction. When making tea with hot water, astringency appears, but 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 for an iced tea extraction method in which tea liquid is extracted over a sufficient period of time with dripping liquid of ice.

[0011] Thereby, tea can be extracted in less than 2 hours while using water just after the ice has melted. More specifically, instead of starting the preparation for tea extraction the night before and drinking it the next morning, for example, when enjoying dinner at a restaurant, the tea leaves and ice are served at the time of seating, and while watching the ice melt and the tea being gradually extracted, one can enjoy dinner with family or friends, and enjoy freshly extracted iced tea during or at the end of dinner.

[0012] [2] The tea extraction method according to the present disclosure includes a step of preparing frozen tea leaves with a size of 1.5 mesh pass or less, and a step of preparing ice with a size of 4 mesh pass or less. The tea is extracted by combining the tea leaves and the ice at room temperature at a ratio of 50 or more and 75 or less of the total weight of the ice to the total weight of the tea leaves.

[0017] Thereby, even if the amount of tea leaves relative to the ice is further reduced, tea can be extracted in less than 2 hours while using water just melted from the ice.

[0018] [5] The tea extraction method according to the present disclosure includes a step of preparing frozen tea leaves with a size of 10 mesh pass or less, and a step of preparing ice with a size of 1.5 mesh pass or less. The tea is extracted by combining the tea leaves and the ice at room temperature at a ratio of 75 or more and 150 or less of the total weight of the ice to the total weight of the tea leaves.

[0019] As a result, even when the amount of tea leaves relative to ice is further reduced and relatively large-sized ice is used, tea can be extracted in less than 2 hours while using water just melted from ice.

[0020] [6] The tea frozen product of the present disclosure includes 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 total weight of the ice is 25 or more and 50 or less with respect to the total weight 1 of the tea leaves, and the tea leaves and the ice are blended.

[0021] As a result, by storing and displaying a pack filled with tea leaves and ice in a freezer at a convenience store, a supermarket, etc. for sale at a predetermined size and ratio, even at home, it is possible to easily extract tea in less than 2 hours while using water just melted from ice.

[0022] [7] The tea frozen product of the present disclosure includes 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 total weight of the ice is 50 or more and 75 or less with respect to the total weight 1 of the tea leaves, and the tea leaves and the ice are blended.

[0023] As a result, even when the amount of tea leaves relative to ice is reduced, by storing and displaying a pack filled with tea leaves and ice in a freezer at a convenience store, a supermarket, etc. for sale at a predetermined size and ratio, even at home, it is possible to easily extract tea in less than 2 hours while using water just melted from ice.

[0024] [8] The tea extraction method according to the present disclosure includes frozen tea leaves having a size of 5 mesh pass or less and ice having a size of 1.5 mesh pass or less, and the total weight of the ice is 50 or more and 75 or less with respect to the total weight 1 of the tea leaves, and the tea leaves and the ice are blended.

[0025] This allows for reducing the amount of tea leaves relative to the ice, and even when using relatively large-sized ice, by storing, displaying, and selling packs filled with tea leaves and ice in a freezer at a convenience store, supermarket, etc. in a predetermined size and ratio, it is possible to easily extract tea at home in less than 2 hours while using water that has just melted from the ice.

[0026] [9] The tea extraction method according to the present disclosure includes frozen tea leaves having a size of 5 mesh passes or less and ice having a size of 2.5 mesh passes or less, and the total weight of the ice is blended with the tea leaves at a ratio of 75 or more and 150 or less with respect to the total weight 1 of the tea leaves.

[0027] This further reduces the amount of tea leaves relative to the ice, and even when using relatively large-sized ice, by storing, displaying, and selling packs filled with tea leaves and ice in a freezer at a convenience store, supermarket, etc. in a predetermined size and ratio, it is possible to easily extract tea at home in less than 2 hours while using water that has just melted from the ice.

[0028]

[0029] This further reduces the amount of tea leaves relative to the ice, and even when using relatively large-sized ice, by storing, displaying, and selling packs filled with tea leaves and ice in a freezer at a convenience store, supermarket, etc. in a predetermined size and ratio, it is possible to easily extract tea at home in less than 2 hours while using water that has just melted from the ice.

[0030]

[11] In the tea extraction method according to the present disclosure, in the method of [1] above, when the mesh opening dimension for sieving the tea leaves is A1 (mm) and the mesh opening dimension for sieving the ice is B1 (mm), the maximum start time for drinking T1 (minutes) is adjusted by adjusting the A1 and the B1. T1 = 42.6×1.027^B1×A1^(0.27 - 0.0031×B1) Extract tea while predicting according to it.

[0031] Thus, while predicting the maximum time when the weight ratio of tea leaves to ice is within a certain range and one can start drinking, tea can be extracted in less than 2 hours using water just melted from ice, so that the timing of serving tea in restaurants or at home can be managed.

[0032]

[12] In the tea extraction method according to the present disclosure, in the method of [2] or [3] above, when the mesh opening size for sieving tea leaves is A2 (mm) and the mesh opening size for sieving ice is B2 (mm), the maximum available start time T2 (minutes) can be obtained by adjusting the A2 and the B2 T2 = 43.7×1.04^B2×A2^(0.27 - 0.0013×B2) Extract tea while predicting according to it.

[0033] Thus, while predicting the maximum time when the amount of tea leaves relative to ice is reduced and the weight ratio of tea leaves to ice is within a certain range and one can start drinking, tea can be extracted in less than 2 hours using water just melted from ice, so that the timing of serving tea in restaurants or at home can be managed.

[0034]

[13] In the tea extraction method according to the present disclosure, in the method of [4] or [5] above, when the mesh opening size for sieving tea leaves is A3 (mm) and the mesh opening size for sieving ice is B3 (mm), the maximum available start time T3 (minutes) can be obtained by adjusting the A3 and the B3 T3 = 53.7×1.03^B3×A3^(0.27 - 0.0053×B3) Extract tea while predicting according to it.

[0035] This makes it possible to predict the maximum time when one can start drinking tea while further reducing the amount of tea leaves relative to ice and setting the weight ratio of tea leaves to ice within a certain range, and to extract tea in less than 2 hours using water just melted from ice. As a result, it becomes possible to manage the timing of serving tea in restaurants and households.

[0036] [Details of Embodiments of the Present Disclosure] Specific examples of the tea extraction method and tea frozen body of the present disclosure will be described below with reference to the drawings. It should be noted 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 equivalent to the claims.

[0037] (Tea Leaves 1) For Tea Leaves 1, various types generally available on the market can be used. Tea Leaves 1 frozen at -18°C or lower are made into various sizes and combined with Ice 2 described below at room temperature to extract tea. Room temperature is defined as being between 15°C and 30°C. The extracted tea can be used for drinking or for cooking.

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

[0039] [Table 1]

[0040] (Ice 2) For Ice 2, any drinking water can be used. Ice 2 frozen at -18°C or lower is made into various sizes and combined 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 the tea leaves 1. The mesh (sieve) and the mesh opening dimension 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 putting water into a mold of a desired size and molding it, or crushing or shaving it from larger ice.

[0042] (Preliminary experiment) First, factors such as the tea leaves 1, the size of the ice 2, the type of tea leaves, and the room temperature were changed to identify the factors and trends that affect the start time of drinkability. The smaller the tea leaves 1, the shorter the start time of drinkability. Similarly, for the ice 2, the smaller it is, the shorter the start time of drinkability. Even when the temperature at which the tea leaves 1 and the ice 2 are frozen is lower than -18°C, there is no significant difference in the start time of drinkability. At a room temperature of 30°C, the start time of drinkability was shorter compared to a room temperature of 15°C. When the ratio of the total weight of the ice 2 to the total weight of the tea leaves 1 was higher, the start time of drinkability became longer. There was no significant difference in the start time of drinkability 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. For the type of tea leaves 1, three types were used: α from a major manufacturer, β from another manufacturer, and γ from yet another manufacturer. The size of the tea leaves 1 was set at 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 the ice 2 was set at 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 the ice 2 to the tea leaves 1 was set at three levels: 25 to 50, 50 to 75, and 75 to 150 for the total weight of the ice 2 with respect to the total weight of 1 of the tea leaves 1. The temperature at which the tea leaves 1 and the ice 2 are frozen was set at -20°C. The room temperature at which the tea leaves 1 and the ice 2 are combined was set at 15°C.

[0044] (Evaluation results) The drinkable start time was evaluated by a taste sensory test by three panelists. The same test was conducted three times (N = 3), and the time when the three panelists evaluated that the taste had reached a level where it could be sufficiently drunk and eaten as tea (the taste was not too weak) was measured, and the longest time was taken as the drinkable start time. With the total weight of ice 2 to the total weight of tea leaf 1 being 25 to 50, 50 to 75, and 75 to 150, the results are shown in Table 2 to Table 4 below respectively. When the drinkable start time exceeded 120 minutes, the experiment was terminated at that point and "exceeded 120" was recorded.

[0045]

[0047]

Table 4

[0048] (Maximum drinkable start time) Figure 1 shows the results of plotting the drinkable start time under the conditions of Table 2 (when the total weight of ice 2 to the total weight of tea leaf 1 was 25 to 50) on a double logarithmic graph. As shown in Figure 1, as described above, the drinkable start time became shorter as the amount of tea leaf 1 was smaller, the amount of ice 2 was smaller, and the ratio of the total weight of ice 2 to the total weight of tea leaf 1 was smaller. Also, in the double logarithmic graph, it was found that the relationship between the drinkable start time and tea leaf 1 could be approximated by a linear function. Based on this result, the maximum value T1 of the drinkable start time under the conditions of Table 2 (when the total weight of ice 2 to the total weight of tea leaf 1 was 25 to 50) was obtained when the mesh opening size for sieving tea leaf 1 was A1 (mm) and the mesh opening size for sieving ice 2 was B1 (mm). T1 = 42.6×1.027^B1×A1^(0.27 - 0.0031×B1) It was found that it can be calculated by an approximate formula (in the formula, "^" represents exponentiation). Similarly, for the maximum value T2 of the drinkable start time under the conditions in Table 3 (when the total weight of ice 2 with respect to the total weight of tea leaves 1 is from 50 to 75), when the mesh opening size for sieving the tea leaves is A2 (mm) and the mesh opening size for sieving the ice is B2 (mm), T2 = 43.7×1.04^B2×A2^(0.27 - 0.0013×B2) It was found that it can be calculated by an approximate formula (in the formula, "^" represents exponentiation). Similarly, for the maximum value T3 of the drinkable start time under the conditions in Table 4 (when the total weight of ice 2 with respect to the total weight of tea leaves 1 is from 75 to 150), when the mesh opening size for sieving the tea leaves is A3 (mm) and the mesh opening size for sieving the ice is B3 (mm), T3 = 53.7×1.03^B3×A3^(0.27 - 0.0053×B3) It was found that it can be calculated by an approximate formula (in the formula, "^" represents exponentiation). As described above, since the maximum time (minutes) when drinking becomes possible can be predicted, it becomes possible to manage the timing of serving tea in restaurants and at home.

[0049] (Tea frozen body 3) The tea frozen body 3 refers to a product obtained by blending and packing tea leaves 1 with a size below a predetermined size and ice 2 with a size below a predetermined size at a predetermined ratio. By storing and displaying the tea frozen body 3 in a freezer in convenience stores, supermarkets, etc. for sale, it becomes possible to easily extract tea in less than 2 hours at home using water with just melted ice. Also, by using the above approximate formulas for T1, T2, and T3 for the tea frozen body 3 and describing the drinkable start time on the package of the tea frozen body, it is possible to provide a tea frozen body 3 that can predict and manage the desired drinkable start time.

By combining tea leaves and ice at room temperature at a ratio of not less than, tea is extracted.

[0051] Thereby, tea can be extracted in less than 2 hours while using water just after the ice has melted. More specifically, instead of starting the preparation for tea extraction the previous night and drinking it the next morning, for example, when enjoying dinner at a restaurant, tea leaves and ice are served at the time of seating, and while watching the ice melt and the tea being gradually extracted, one can enjoy dinner with family, friends, etc., and enjoy freshly extracted iced tea during or at the end of dinner.

[0059] Thereby, even if the amount of tea leaves relative to ice is further reduced and ice of a relatively large size is used, tea can be extracted in less than 2 hours while using water just after the ice has melted.

[0060] [6] The tea frozen body of the present disclosure includes frozen tea leaves having a size of 1.5 mesh passes or less and ice having a size of 1.5 mesh passes or less, and tea leaves and ice are blended at a ratio of the total weight of ice to the total weight of tea leaves of 25 or more and 50 or less.

[0062] [7] The tea frozen body of the present disclosure includes frozen tea leaves having a size of 1.5 mesh passes or less and ice having a size of 4 mesh passes or less, and tea leaves and ice are blended at a ratio of the total weight of ice to the total weight of tea leaves of 50 or more and 75 or less.
