Description

The present invention relates to instant powdered tea.

In recent years, various beverages have been put on the market due to the diversification of consumer tastes and the rise of health consciousness. One such tea beverage is instant powdered tea that can be easily drunk by simply putting it in a container such as a cup and pouring hot water or the like without using a teapot or teapot. Instant powdered tea is suitable for carrying around, and there are increasing opportunities to carry and drink it at work, business trips, travel destinations, and so on.

Conventionally, as instant powdered tea, for example, a purified green tea extract obtained by purifying a green tea extract in a mixed solution having a mass ratio of ethanol and water of 99/1 to 75/25 is 0.5 to 0.5 to 20.0% by mass and 0.01 to 10.0% by mass of hydroxycarboxylic acid or a lactone thereof or a salt thereof are blended to make the content of non-polymer catechins 0.5 to 15.0% by mass. As a result, while containing a high concentration of non-polymer catechins, bitterness and astringent taste are reduced, the flavor is good, and the flavor and appearance stability can be maintained for a long time even after being reduced to the beverage. (Patent Document 1), tea polyphenols, catechins and strictinin are contained, and 70% by weight or more of the catechins are epi-catechins, so that the tea polyphenols are contained in a high concentration. , Instant powdered tea (Patent Document 2), which has excellent tea's original flavor, flavor and mouthfeel, and has both palatability and functionality, green tea extract, antioxidants, powdered tea and potassium are contained to increase the potassium content. By setting the content to 0.8 to 5.6% by mass, sufficient taste and aroma can be obtained during drinking, the powder color and light blue during drinking show a bright green color, and from the time when the powder is dissolved to the end of drinking. Instant green tea (Patent Document 3) in which powdered tea does not easily settle has been proposed.

As the tea leaves, one kind or two or more kinds can be used, but among them, green tea is preferable from the viewpoint of polyphenol content. As the extraction method, known methods such as stirring extraction and column extraction can be adopted. Further, as the green tea extract, a commercially available product may be used, and examples thereof include "Polyphenone" manufactured by Mitsui Norin Co., Ltd., "Theafran" manufactured by Itoen Co., Ltd., and "Sanphenon" manufactured by Taiyo Kagaku Co., Ltd. Further, as the green tea extract, a purified green tea extract may be used. Examples of the purification method include the methods described in JP-A-2004-147508, JP-A-2004-149416, JP-A-2007-282568, and the like.

Further, in order to control the contents of the components (a), (b), (e) and (f) in the instant powdered tea and their ratios, for example, warm water is brought into contact with the surface of the tea leaves, and the tea leaves are brought into contact with each other. After the tea leaves are extracted with water and separated into solid and liquid, a tea extract subjected to tannase treatment can be used if necessary. By adjusting the contact conditions (temperature, time, etc.), extraction conditions (temperature, time, etc.), tannase treatment conditions (concentration, time, etc.) of the tea leaves with warm water, the components (a) of the tea extract, The contents of (b), (e) and (f) and their ratios can be controlled. Here, the term "tannase treatment" as used herein means that the tea extract is brought into contact with an enzyme having tannase activity, and the treatment conditions can be referred to, for example, Japanese Patent Application Laid-Open No. 2004-321105. it can. The tannase treatment decomposes the gallates of non-polymeric catechins in the tea extract and liberates gallic acid.
