Description

Container filled with non-tea drinks

The present invention relates to a container-packed non-tea beverage, which comprises a high concentration of catechin by adding a purified green tea extract, and which has a reduced astringency and a moderate sweetness and sourness, although it contains a sweetener. Also suitable for long-term preservation.

The physiological effect of catechins has been reported to have an effect of suppressing an increase in cholesterol or an action of blocking amylase activity (for example, refer to Patent Documents 1 and 2). In order to make the catechins exhibit the physiological effects as described above, adults need to drink 4 to 5 cups of tea per day. Therefore, in order to more easily ingest a large amount of catechins, the manufacturer expects to add a high concentration of catechins to the beverage. technology. As one of the methods, there is a method in which a catechin is added to a beverage in a dissolved state by using a concentrate of green tea extract (for example, refer to Patent Documents 3 to 5).

However, if the concentrate of the commercially available green tea extract is directly used, the astringency or bitterness is strong and the throat is poor due to the influence of the synthesized component in the concentrate of the green tea extract. At present, in order to obtain the adaptability for long-term drinking for the physiological effect of catechin, and adding a sweetener to be able to drink for a long period of time, there is a stability of the non-polymer catechin itself at a high temperature. problem.

The present invention provides a container-packed non-tea beverage in which a purified product of green tea extract is added, and (A) a non-polymer catechin is 0.01 to 1.0% by mass, and (B) a non-polymer catechin The non-body ratio is 5 to 25% by mass, (C) the pH is 2.5 to 5.1, and contains 0.0001 to 20% by mass of (D) self-fructose, glucose, sucrose, glucose fructose liquid sugar, and fructose glucose liquid sugar. Choose one or more of them.

The present invention provides a container-packed non-tea-based beverage, which comprises a high concentration of catechin by adding a purified product of green tea extract, and takes into consideration the reduction of astringency and moderate sweetness and sourness, although it contains a sweetener. The catechin content can be maintained even after long-term storage.

The present inventors have studied the flavor of a green tea beverage containing a high concentration of catechins, and found that the pH can be controlled by the non-body ratio of non-polymer catechins. The amount of the specific sweetener is obtained, and a container-packed non-tea-based beverage which maintains the catechin content even if it contains a sweetener and has a moderate sweetness and sourness, and which contains a sweetener, is preserved.

The container-packed non-tea beverage of the present invention adjusts the pH value and selects a sweetener in order to control the non-body ratio of the non-polymer catechins, thereby achieving both a reduction in astringency and a moderate sweetness and sourness. And, although it contains a sweetener, it retains the catechin content even after long-term storage.

In the present invention, the term "A) non-polymer catechins refers to catechin, gallocatechin, catechin gallate, gallic catechin gallate. Non-epidermal catechins, as well as epicatechins, epigallocatechin, epicatechin gallate, epigallocatechin gallate, etc. The general term for the combination of the genus, the concentration of the non-polymer catechins is defined based on the total of the above eight kinds.

Catechins. If the content of the non-polymer catechins is within this range, a large amount of non-polymer catechins can be easily taken in, and thus it is desirable to obtain physiological effects of non-polymer catechins. Further, when the content of the non-polymer catechins is less than 0.01% by mass, the physiological effects of the non-polymer catechins cannot be expected. Further, if the content of the non-polymer catechins exceeds 1.0% by mass, the bitterness of the beverage increases.

The non-polymer catechins in the container-packed non-tea beverages of the present invention are: comprising epigallocatechin gallate, epigallocatechin, epicatechin The body of the catechin and epicatechin, and the non-table of catechin gallate, gallocatechin gallate, gallocatechin, and catechin body.
