CONSTITUTION:Firstly, large-sized ice blocks 2 and a frozen product 3 of a beverage stock solution (e.g., coffee, fruit juice) are each prepared by freezing separately. These two kinds of products 2 and 3 are then put into container 1b capable of uniform thawing with microwave followed by fitting with a cap 1a to effect sealing, thus obtaining a large-sized ice block-contg. frozen beverage. The objective large-sized ice block-contg. beverage can readily be obtained by simply thawing the above frozen beverage, together with the container, in a microwave oven. With no high-temperature and high-pressure sterilization process in putting said two kinds of frozen products into the container, the flavor inherent in the beverage will not be impaired. Furthermore, because of being frozen, this beverage can be stored for a long period, causing no flavor deterioration during storage.

Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a beverage containing large ice cubes that can be thawed at home using a microwave oven or the like to easily obtain a cold beverage with ice floating on it. .

(Prior Art) In general, cold drinks such as full-fledged iced coffee and fresh juices served at coffee shops etc. are regular coffee extracted from roasted coffee beans, fresh juice made by squeezing fruit, etc. After adding sugar as appropriate, it is cooled and drunk with ice cubes floating on top. Such drinks with ice floating on them are in great demand, especially in the summer, because they feel cold when drunk and have a cool appearance.

However, it is difficult and time-consuming to prepare ice of an appropriate size and liquid for beverages such as coffee or fruit juice (drinking liquid, hereinafter the same) in advance, so this method is not used at home. It is rarely made using authentic methods.

Therefore, beverages packaged in sealed containers such as cans and paper cartons are commercially available as convenient cold beverages, but these beverages packaged in sealed containers are all sterilized at high temperature and pressure to prevent the growth of bacteria during distribution and storage. Because of this, most of the original fresh flavor of the beverage is lost and a unique heated odor (retort odor) is produced.

For this reason, at present, a beverage that satisfies both the original flavor of a full-fledged beverage and its convenience has not yet been obtained.

(Problems to be Solved by the Present Invention) The present invention has been made in view of the above circumstances, and its purpose is to easily provide beverages such as regular coffee and fresh juice without impairing their original flavor. To provide a beverage containing large ice cubes that can be used to make a cold beverage and can be stored for a long time.

(Means for Solving the Problem) The above object is a large ice block in which a large ice block and a frozen drinking liquid are stored in a container that can be uniformly thawed using microwaves. This can be achieved by using beverages containing alcoholic beverages.

That is, the present inventors have discovered that if the drinking liquid is frozen, it can be distributed and stored without high-temperature and high-pressure sterilization, and the original fresh flavor of the beverage can be maintained until the time of drinking, and the above-mentioned method of the present invention This invention was achieved by discovering that when a packaged beverage is thawed in a microwave, only the drinking liquid thaws in a short time, while the ice hardly melts and remains as it is, resulting in a beverage containing large ice cubes. did.

Next, the present invention will be explained in detail.

The basic structure of the beverage containing large ice cubes of the present invention is shown in FIG. In the figure, (1) is a storage container, (2) is a large ice block, and G) is a frozen drinking liquid.

The material for the container (1) used in this invention may be appropriately selected from thermoplastic plastics and the like conventionally used for microwave ovens.

Further, although the shape and structure of the container is not particularly limited, an example thereof will be explained with reference to drawing ζ.A lid portion (1a) as shown in FIG. It is preferable to have a structure in which the product is tightly fitted, since the flavor will not be lost during storage or heating.

Next, a large ice block (
For 2), ice that is normally used is sufficient. Although its size is not particularly limited, it is preferably about 25 to 35 mm so that it maintains its original shape when thawed and remains appropriately cold when drinking.

The beverage containing large ice cubes of the present invention can be obtained, for example, as follows. That is, first, a drinking liquid appropriately selected from coffee, milkshake, juice, soup, soup, cocktail, etc., and a large ice cube) are filled into the container <1). These may be mixed in advance or may be filled simultaneously. Next, by freezing this mixture, a beverage containing large ice cubes can be obtained.

The mixing ratio of large ice cubes (about the size of a large ice cube) and drinking liquid is
) is 20 to 80% by weight (hereinafter abbreviated as "whisper") of the entire contents (total contents to be placed in the container (1), the same applies hereinafter), and good results can be obtained if the beverage part liquid is also set to 80 to 20%. .

The above-mentioned drinking part liquid preferably has a total solid content of 10% or more, preferably 10% or more, so that only the frozen part (3) of the drinking part liquid thaws in a short time when heated in a microwave oven or the like. is 15~
It is preferable to set it to 35%.

Furthermore, a stabilizer or the like may be added to the drinking liquid, or ingredients such as fruits or seafood may be added.

Moreover, the large ice block (2) is not limited to the conventional ice made from water, but may also be filled with carbon dioxide gas, or may be flavored or colored. At this time, large ice blocks (
Good results can be obtained by setting the total solid content to be less than the total solid content of the drinking liquid, preferably 10% or less, so that 2) maintains its original shape.

The beverage thus obtained can be easily made into a cold beverage with the original fresh flavor of the beverage by simply heating the entire container in a microwavable oven or the like for 2 to 3 minutes. Furthermore, it is possible to color or flavor the large ice block (2) and add viscosity to the drinking liquid, so you can enjoy a wide variety of appearance and flavor.

(Effects of the Invention) As described above, the beverage containing large ice blocks of the present invention can be easily obtained by simply thawing the entire container in a microwave oven. Moreover, unlike conventional drinks packaged in sealed containers, a high-temperature and high-pressure sterilization process is not performed when filling the container, so the original flavor of the drink is not impaired. Furthermore, since it is stored frozen, it can be stored for a long period of time, and the flavor does not deteriorate during storage.

In addition, by increasing the viscosity as needed, shortening the thawing time to create a semi-liquid beverage, and adding flavor or color to the ice cubes, the beverage is much richer in flavor than conventional beverages packaged in sealed containers. We were able to obtain a wide variety of drinks.

Next, the present invention will be specifically explained with reference to Examples.

[Examples 1 to 10. Comparative Examples 1-2] Drinking liquid and large ice cubes were prepared as follows.

Next, a beverage was produced using the drinking liquid and large ice cubes prepared as described above.

(Examples 1 to 10, Comparative Example 1) The coffee drinking tribe was cooled to 10°C and filled in a 200 ml capacity microwave oven container (polypropylene container manufactured by Idemitsu Petrochemical Co., Ltd.) together with large ice cubes at the proportions shown in the table below. The total internal volume was 200 ml, and it was frozen and stored at 86°C for 2 hours. Next, this frozen beverage was heated in an Osaka Gas combination range (GMO-M8000 model, oscillation frequency: 2450 Hz) for the time shown in the table below, thawed, and made into iced coffee containing large ice cubes.

(Comparative Example 2) The coffee beverage was filled into a 190ml steel can, retorted at 116°C for 115 minutes, and then cooled and stored at 10°C for 2 hours to obtain canned iced coffee.

Next, 10 expert panelists drank and evaluated the flavor of these example products and comparative samples. Regarding oral properties, Example products 1 to 10 and Comparative survey 1 were kept at -s5°C for 3 months, and Comparative survey 2 was kept at -s5°C for 2 months.
Each sample was stored at 0°C for 3 months and then consumed by 10 expert panelists to evaluate its flavor.

These results are also shown in the table below.

From the above results, the drinks of the examples all have good flavor, and since the ice blocks remain almost as raw materials, the coldness when drinking is added to the cool appearance, resulting in good results. Obtained. On the other hand, in the beverage of Comparative Example 1, in which the solid content of the beverage liquid was small, the aroma disappeared and most of the ice cubes melted, making it watery. Moreover, in Comparative Example 2, which is a regular canned coffee, a so-called retort odor originating from retort sterilization was felt.

In addition, when we investigated the changes in the beverages of Example 2 and Comparative Example 2 after 3 months, it was found that Example 2 clearly maintained the original flavor of regular coffee and received higher evaluations. On the other hand, Comparative Example 2 had a strong retort odor, which was not desirable.
