Description

The present invention relates to a packaged beverage in which an edible solid and a liquid are housed in a sealed container.

Packaged beverages, which are obtained by filling and sealing beverages into various containers such as cans and resin containers, can be stored for a relatively long time, are highly portable, and are easily available. It is widely used due to its height. In addition, packaged beverages are widely popular among consumers as RTD beverages (Ready to Drink), which can be consumed immediately after opening.

Refrigerated packaged beverages are suitable for drinking when they are sufficiently cold, but if you are carrying them around in the summer or drinking them over time after opening (so-called ``chibi-dara-nomi''), you should take them outside. There was a problem in that the temperature of the liquid content of the beverage gradually rose due to the influence of temperature and other factors, making it lukewarm and the flavor of the beverage decreasing.

Therefore, techniques have been proposed for maintaining the temperature of the liquid contained in a packaged beverage at a low level. For example, Patent Document 1 proposes ice for PET bottle beverages in which ice of a size to be poured from the opening of the PET bottle is stored in a container, and Patent Document 2 proposes A cylindrical cooling holder is described which has a diameter smaller than the opening diameter of a PET bottle and which can be poured into the bottle.

Furthermore, for packaged beverages containing fruit juice, it has been proposed to suppress changes in the flavor of the beverage by devising the composition of the beverage, even if the temperature of the content changes due to drinking. In other words, Patent Document 3 states that the Brix value is adjusted to 0.4 to 5.0, predetermined tea-derived polyphenols are adjusted to a fruit juice-containing beverage containing fruit juice-derived polyphenols, and no sweetener is added. As a result, although the fruitiness and flavor are good when it is cold, the fruit juice does not feel heavy even when the temperature of the solution in the drink rises, and it does not feel sticky in the mouth after drinking. It is described that it does not cause a feeling of bitterness and maintains a sharp aftertaste (a feeling of sharpness).

It is a side view showing one aspect of a beverage container. FIG. 2 is a schematic diagram showing a piece of peach pulp used in Experiment 1. 3 is a graph showing the results of Experiment 1. FIG. 2 is a schematic diagram showing a piece of pineapple pulp used in Experiment 2. 3 is a graph showing the results of Experiment 2.

The beverage of the present invention is a packaged beverage containing an edible solid and a liquid. The term "edible solids" as used herein refers to edible solids such as fruits and gel foods. There are no particular restrictions on fruits, but stone fruits such as peaches and cherries, citrus fruits such as lemons, oranges, grapefruits, and tangerines, pome fruits such as pears and apples, and tropical fruits such as kiwi fruits, mangoes, papayas, and bananas. Examples include fruit vegetables such as strawberries, pineapples, melons, and watermelons, and fruits other than these such as grapes and blueberries. Further, in this specification, for convenience, aloe mesophyll is also treated as a fruit. The fruit may be a fresh fruit or a processed fruit that has been subjected to treatments such as freezing and/or sugar immersion. Furthermore, when fruit pieces are used as the edible solid, they may or may not have a pericarp attached to them. Examples of gel-like foods include, but are not particularly limited to, nata de coco, agar, gelatin, konjac gel, and jelly-like foods prepared with other gelling agents.

The beverage of the present invention is characterized in that it contains edible solids having a specific size, and utilizes the cooling retention (cold storage) function of the solids to suppress the rise in temperature of the beverage content. The edible solid material required for the cold storage function has a volume of 4.0 cm ³ or more, preferably 6.0 cm ³ or more, more preferably 8.0 cm ³ or more, 10.0 cm ³ or more, or 12.0 cm ^{3 or more} . It may be more than that. Generally, when a packaged beverage is taken out of the refrigerator, the temperature of the liquid content gradually rises due to the influence of the outside temperature, etc., but if it contains solids with the above-mentioned specific size, it may not be contained. Compared to this, it is possible to reduce the temperature rise of the content liquid. The size of the solid substance is not limited as long as it can be accommodated in the container, but for example, it is 100 cm ³ or less, preferably 80 cm ³ or less, more preferably 60 cm ³ or less, 50 cm ^{3 or less, or 40 cm 3 or} less. Good too.

The effects of the present invention are more effectively expressed by containing a plurality of solids of 4.0 cm ³ or more. In a preferred embodiment, the beverage of the present invention contains 3 or more solids of 4.0 cm ³ or more, preferably 4 or more, more preferably 5 or more. There is no particular upper limit to the number of solids to be included, but it can be, for example, 20 or less, 15 or less, or 12 or less.

In order to achieve the desired effect of the present invention, the ratio of the edible solid material that becomes the cold storage body and the content liquid is also important. That is, in the present invention, the amount of edible solids is 10 to 50% by weight, preferably 15 to 45% by weight, more preferably about 20 to 40% by weight, based on the total amount of the beverage. Here, the total amount of beverage means the combined weight of edible solids and liquid, and does not include the weight of the container.

Although the shape of the solid object is not particularly limited, a thick shape such as a substantially cube or rectangular parallelepiped tends to store cold more easily than a thin plate shape. Therefore, the solid material preferably has a thick shape such as a substantially cube or rectangular parallelepiped. When fruit is used as the solid material, fruit cut into dice or wedges can be suitably used. For example, the thickness of the solid material is 0.3 cm or more, preferably 0.5 cm or more, more preferably 0.8 cm or more, and still more preferably 1.0 cm or more. Here, when referring to the thickness of the solid material in this specification, it refers to the shortest length of each section of the solid material.

When the temperature of the liquid content in a beverage rises due to the influence of outside temperature, etc., it is possible to suppress the temperature rise of the liquid content by slowly replacing the cooled water in the edible solids. It is inferred. Therefore, it is preferable that the edible solid has a structure containing a large amount of water. Solids containing a lot of water refer to gel-like foods, fruit pulp, etc., and specifically, solids containing water at 85% by weight or more, preferably 90% by weight or more, more preferably 95% by weight or more. . Here, the pulp refers to the edible part of the fruit, excluding the inedible parts (peel, seeds, etc.). Generally, the moisture content of the inedible parts of fruits is about 60 to 80% by weight. A pulp piece whose solid matter consists only of edible parts is an example of a preferred embodiment of the present invention.

The beverage of the present invention suppresses the rise in temperature of the liquid portion by incorporating a specific amount of edible solid matter having a specific size. If the shape of the edible solid material collapses, melts, dissolves, or otherwise changes during the production, storage, or transportation of beverages, the appearance and texture of the liquid portion may be affected, or the intended purpose of the present invention may be affected. may inhibit the effectiveness of Preferably, the edible solids are heat resistant, such as fruit or heat resistant jelly. Examples of heat-resistant jelly include jelly made from any one or more selected from agar, pectin, glucomannan, alginate, and gellan gum, and nata de coco made by fermenting coconut juice to form a gel.

From the viewpoint of suppressing the collapse of the shape of the edible solid, the hardness of the edible solid in the beverage of the present invention is preferably 80 g/cm ² or more. It is more preferably 100 g/cm ² or more, even more preferably 200 g/cm ² or more, and particularly preferably 300 g/cm ² or more. The upper limit of the hardness is not particularly limited, but from the viewpoint of being able to be enjoyed with a drink, it is preferably 1500 g/cm ² or less, more preferably 1300 g/cm ² or less, and even more preferably 1000 g/cm ² or less. Here, the hardness in this specification means the breaking strength (unit: g/cm ² ) when a solid material breaks, and specifically, the hardness refers to the breaking strength (unit: g/cm 2 ) of a solid material. S), the breaking strength when the solid material breaks can be measured under measurement conditions (compression test) using a spherical plunger with a diameter of 10 mm and an entry speed of 300 mm/min.

The edible solids in the beverage of the present invention are relatively large in size, 4 cm ³ or more, and typically do not float in the beverage but are deposited near the bottom of the container. If the content of the packaged beverage is too large, the intended effect of the present invention may not be fully exhibited, so the beverage of the present invention preferably has a total amount of approximately 100 to 400 g. More preferably, it is 140 to 350 g or 180 to 300 g. Here, the total amount of beverage refers to the combined weight of edible solids and liquid.

The beverage of the present invention contains an edible solid and a liquid (liquid content). The liquid is not particularly limited as long as it is a drinkable liquid. Examples of liquids related to the beverage of the present invention include water, near water, fruit juice drinks, milk drinks, milk drinks, tea drinks, coffee drinks, and other soft drinks. In a preferred embodiment, a tea beverage can be used as the liquid, including teas made from tea leaves produced using the leaves and stems of the tea plant (Camellia sinensis) (unfermented teas such as green tea, oolong teas, etc.). In addition to semi-fermented teas such as semi-fermented teas and fermented teas such as black tea, extracts made from plants such as herbal teas (tea beverages in a broad sense) can be used. Although the beverage according to the present invention may be an alcoholic beverage, it may also be a non-alcoholic beverage such as a soft drink. Alcohol such as ethanol has a lower thermal conductivity than water, so when the beverage of the present invention is an alcoholic beverage, the problems of the present invention are less likely to occur. In view of the remarkable effects of the present invention, the beverage of the present invention is preferably a non-alcoholic beverage. Here, the non-alcoholic beverage refers to a beverage with an alcohol content of less than 1 v/v%.

In a non-alcoholic beverage, it is preferable to contain a trace amount of ethanol of 0.001 v/v% or more and less than 1 v/v%. When a very small amount of ethanol molecules are mixed in the water molecules, the heat in the water molecules is absorbed by the heat of vaporization of ethanol, so that the temperature rise of the content liquid can be further suppressed.

In addition to the above-mentioned components, the liquid part of the present invention may contain various components that can be used for beverage preparation as necessary (for example, "Latest Soft Drinks", National Soft Drink Industry Association (see Korin et al., 2003). For example, it may contain sugars such as sugar, fructose, pH adjusters such as sodium bicarbonate, antioxidants such as vitamin C, sweeteners, fragrances, pigments, preservatives, seasonings, vitamins, calcium, amino acids, etc. good.

Packaged Beverage The beverage of the present invention is a packaged beverage in which an edible solid and a liquid (liquid content) are housed in a sealed container. The material of the container may be any material commonly used for beverages, such as paper, resin (plastic), metal, or glass. However, if a resin container with low thermal conductivity is used, the effects of the present invention will be reduced. This is an example of a preferred embodiment because it is easy to enjoy. The resin container may be flexible, but is preferably a molded hard container, particularly preferably a resin container with a thickness of 0.3 mm or more, and a resin container with a thickness of 0.4 mm or more. A resin container is more preferred. An example of such a container is a plastic cup container having a substantially trapezoidal cross section and a fully open opening as shown in FIG. 1, and when the container is sealed, the upper opening may be sealed with a film or the like.

By using the edible solid as a cold storage body, the beverage of the present invention has the effect of suppressing the temperature rise of the liquid content, and at the same time has the effect of imparting changes in texture and taste to the beverage. In other words, if the cooling retainer (cold storage body) is ice, the liquid content will become diluted as the ice melts, but in the beverage of the present invention, the taste of the liquid content does not dilute, and the solid food can be absorbed. You can also enjoy the feeling. Therefore, it is preferable that the container of the present invention has a large opening for easy removal of solids. Specifically, a container having an opening diameter of 5 to 15 cm is preferably used.

The packaged beverage according to the present invention may be consumed as it is as an RTD beverage (RTD = Ready To Drink: packaged beverage that can be drunk immediately after opening the lid), but it can be used as an RTS beverage (RTS = Ready To Serve) with ice or carbonated beverage. You may mix it with water and drink it. In addition, since the packaged beverage according to the present invention contains relatively large edible solid pieces, it may be labeled as a pulp-containing food or drink on food labeling.

In one embodiment, the present invention is a method for producing a packaged beverage. Although not particularly limited, when producing the packaged beverage of the present invention, the step of preparing edible solids with a size of 4 cm ³ or more, the step of preparing the content liquid, and the step of preparing the edible solids in a proportion of 10 to 50% by weight. A step of filling a container with the edible solid and the liquid content and sealing the container, a step of heating and sterilizing the container, etc. may be performed.
