Description

The present invention relates to a packaged black tea beverage containing a black tea extract and at least one or more fruit components selected from apples and peaches, and a method for producing the same.

The method of drinking sliced fruits floating on black tea has been popular for a long time both in Japan and abroad, and it is a method of drinking fruit tea that is widely used not only in ordinary households but also in coffee shops.

Recently, however, the number of stores that offer such fruit tea in a take-out style (for example, juice stands) is increasing at railway stations and department stores, and is gaining widespread popularity, especially among women.

However, it is technically extremely difficult to reproduce such a way of drinking, that is, a beverage that industrially provides fruit tea with a texture similar to that of sliced fruit floating on black tea, that is, a packaged black tea beverage (RTD). Met.
There are several reasons for this, and one of them is that the packaged black tea beverage (RTD) as an industrial product is legally required to be heat sterilized because it is supposed to be stored for a certain period of time. Since such heat sterilization treatment causes heat deterioration and deterioration over time, it can be mentioned that the drinks are not similar to those provided in ordinary homes and stores (juice stands).

In order to solve such problems, companies that industrially provide packaged black tea beverages (RTDs) use auxiliary materials such as spices to perform heat sterilization, which is legally required. , I have tried to provide something similar to what is offered at ordinary homes and stores (juice stands). As a result, changes in quality due to heat sterilization can be controlled to a certain extent, but by using auxiliary materials such as fragrances that are never used in ordinary households, etc., what is provided in ordinary households, etc. It was still similar but not similar.

By the way, attempts to reproduce fruit tea as an industrially packaged black tea beverage (RTD) have been made in various forms so far.
For example, Patent Document 1 discloses an apple-flavored food composition that imparts an apple-like acidity and an apple flavor that can improve the sharpness of the aftertaste even when the fruit juice content is less than 10 wt%. ..

Patent Document 2 describes a packaged black tea beverage containing 10 to 90% by mass of fruit juice, which contains 10 ppm to 24 ppm of theogallin and the ratio of theogallin content to potassium content (theogallin / K). A packaged black tea beverage containing fruit juice is disclosed, wherein the value is 0.015 to 0.100.

Patent Document 3 describes a packaged black tea beverage containing 0.001 to 0.005% by mass of caffeine and containing a sweetener and fruit juice, and has an acidity in the range of 0.02 to 0.08%. Disclosed is a packaged black tea beverage, which is characterized in that the sweetness and spiciness represented by the sugar content and the acidity when the acidity is in the above range is in the range of 1.50 to 2.50.

Patent Document 4 describes a packaged non-alcoholic fruit juice-containing black tea beverage containing one or more types of fruit juice selected from the group consisting of muscat, peach, orange, bergamot, and apple, and having a Brix value of 0.4 to. It is 5.0, the amount of black tea-derived polyphenols is 10 to 400 ppm, the amount of fruit juice-derived polyphenols is 0.6 to 150 ppm, no sweetener is added, and the caffeine content is 100 ppm or less. Disclosed is a packaged non-alcoholic fruit juice-containing black tea beverage.

Hereinafter, an example of the embodiment of the present invention will be described. However, the technical scope of the present invention is not limited to one example of the following embodiments.

<Contained black tea beverage>
The packaged black tea beverage of the present invention contains a black tea liquid component and at least one or more fruit components selected from apples and peaches, and the content liquid (hereinafter, also referred to as a beverage liquid) filled in the container is It has turbidity.
Here, the packaged black tea beverage refers to a beverage in which the beverage liquid is packaged and subjected to heat sterilization treatment required by laws and regulations.
Further, the “turbidity” of the container-filled black tea beverage in the present invention means that the content liquid is turbid and not transparent. Specifically, when the content liquid after filling the container is referred to as pure water. The value when the transmittance (T%) at 660 nm is measured is 90% or less.

The packaged black tea beverage of the present invention is an industrial product that can be distributed on the market, and a storage period of a certain period (so-called best-by date) is guaranteed. Therefore, the packaged black tea beverage of the present invention is technically and industrially different in nature from the beverage prepared at home, restaurants, etc. and immediately consumed (for example, "Latest Soft Drinks". ], Supervised by the Japan Soft Drink Association, Korin, 2003).
In addition, for black tea beverages that are packed in containers, it is necessary to write the product name on the packaging materials such as containers and labels as required by laws and regulations. The product name of the packaged black tea beverage of the present invention is not particularly limited. However, since it contains at least a black tea liquid component and a fruit component, it may be a black tea beverage, a fruit juice beverage, a beverage containing fruit juice, a soft drink, or the like.
In addition, the packaged black tea beverage of the present invention is preferably in a mode (so-called single strength) in which it can be drunk as it is without being diluted after opening the cap.

(Black tea liquid component)
In the present invention, the black tea liquid component means a liquid component containing a component derived from black tea leaves. For example, a liquid obtained by extracting black tea leaves (black tea leaf extract) or a black tea leaf extract is concentrated. The obtained concentrate (black tea leaf concentrate), the dried product obtained by drying the black tea leaf extract (black tea leaf dried product), and the dried product obtained by drying the black tea leaf concentrate (black tea leaf concentrated dried product). ), Etc., and one or more of these may be used as required.
Further, in preparing these, various known techniques such as solid-liquid separation, activated carbon treatment, enzyme treatment and the like may be appropriately selected and carried out.
In addition, the packaged black tea beverage of the present invention does not exclude the use of food additives (flavors) that impart a part of aroma and taste to foods. However, due to the recent tendency of consumers to avoid additives, it is preferable not to use such food additives (flavors).

As the above-mentioned black tea leaves, black tea leaves generally used in black tea beverages, that is, tea leaves obtained by fermenting raw tea leaves and making tea as needed can be used.
The tea season, production area, variety, grade, fermentation conditions, etc. of black tea leaves are not particularly limited. For example, it may be a Chinese variety (var. Siennesis), an Assam variety (var. Assamica), or a blend of two or more types of tea leaves.

Whether or not the packaged black tea beverage contains black tea liquid components can be determined by the product name, raw material name, and other items described on the packaging material such as the container and the label.

(Discussion)
Based on the above examples and various test results that the present invention has conducted so far, it is a black tea beverage that is a packaged black tea beverage containing a black tea extract and at least one or more fruit components selected from apples and peaches. It contains 5.0 to 45.0 mg / 100 mL of polyphenols, the content ratio of black tea polyphenols to black tea (black tea polyphenols / malic acid) is 0.35-10.00, and the permeability (T%) is high. If it is 45.0 to 90.0%, the strength of the flavor of black tea, the sharpness of the aftertaste due to the acidity, and the strength of the turbidity are highly evaluated as compared with the conventional packaged beverage (RTD), and the juice. It turned out that you can feel the fruit tea that is served at the stands.
In addition, when the fruit component of orange fruit or grape fruit is contained, the sourness is not compatible with malic acid, the sourness is conspicuous, the sourness becomes heavy, and the aroma of tea and the freshness of the fruit tend to be difficult to feel. there were.

Further, in order to produce such a packaged beverage, an extract is used in a method for producing a packaged beverage, which comprises a step of combining black tea leaves and one or more kinds of fruits selected from apples and peaches and extracting them together. The amount of tannins in the extract was adjusted to 5.0 mg / 100 mL to 45.0 mg / 100 mL, and the content ratio of black tea polyphenols to black tea (black tea polyphenols / apple acid) in the extract was 0.35 to 10.00. It was also found that it is preferable to adjust and adjust the transmission rate (T%) to 45.0 to 90.0%.

The fruit component of peach is similar to that of apple, and in both cases, the main organic acid contained in the fruit is malic acid, and the content ratio of malic acid is also the same. Therefore, it is considered that the same effect can be obtained when the fruit component of peach is used instead of the fruit component of apple.
