Embodiment

[0069] The present invention is more specifically illustrated by the following examples, but the present invention is not limited to these examples.

reference example 1

[0071] After adjusting pectin (trade name pectin (sugar-free), manufactured by Nacalai Tesque Co., Ltd.) to 0.5% by weight with acetate buffer solution pH 5.4, commercially available cellulase for food addition (trade name Cellulase A "Amano" 3 (manufactured by Amano Enzyme Co., Ltd.), product name Cellulase T "Amano" 4 (manufactured by Amano Enzyme Co., Ltd.), product name Cellulosin AC (manufactured by HBI Co., Ltd.), product name Cellulosin T3 ( (manufactured by HBI Corporation), brand name Sumizyme C (manufactured by Shin Nippon Chemical Industry Co., Ltd.)) was added to 1% by weight with respect to the pectin in the test solution. After reacting at 37°C for 16 hours, treat at 90°C for 10 minutes to inactivate the enzyme activity. Thereafter, the viscosity was measured at 24.5° C. with a tuning fork vibrating viscometer SV-A (manufactured by A&D Co., Ltd.). As a result, such as figure 1 As shown, the cellulase T "Amano" 4 and Sumizyme C basically do not produce viscosity...

Embodiment 1

[0073] Extract 5 g of pulverized Sencha tea leaves with 500 g of hot water for 3 minutes once (20% extraction rate of soluble components) or twice (40% extraction rate of soluble components), perform solid-liquid separation, and add cellulase T "Amano" 4 (Amano Enzyme Co., Ltd.), made it 1% by weight with respect to the weight of tea leaves, and added 15 times the pure water of the weight of tea leaves. Furthermore, about 0.5% by weight of the weight of the tea leaves was added with L-ascorbic acid to adjust the pH to 4.6. Thereafter, the reaction was carried out at 37°C for 16 hours, and the enzyme activity was inactivated by treating at 90°C for 10 minutes to terminate the reaction. The tea enzyme-treated extract was recovered by solid-liquid separation, and the viscosity was measured with a tuning fork vibrating viscometer SV-A (manufactured by A&D Co., Ltd.). As a control, the same operation was carried out without adding the enzyme, and its viscosity was measured. The r...

Abstract

Provided are a tea extract imparting a palatable body, and a tea beverage containing the same. Specifically provided is a tea extract extracted after treating tea leaves using a cellulase exhibiting little contaminating pectinase activity.

Description

technical field [0001] The present invention relates to a method for producing a novel tea extract having a good mouthfeel and full body characteristic of high-grade tea, a high-viscosity tea extract obtained by the method, and a container-packed tea beverage containing the extract. Background technique [0002] It is known that high-grade tea leaves such as Gyokuro have rich taste and aroma, and also have a unique richness that is not usually found in sencha. Therefore, as a method of extracting useful ingredients contained in high-grade tea leaves from tea leaves to enhance the taste and aroma, and a method of extracting unextractable useful ingredients from residues, the following methods are disclosed. [0003] For example, a tea extract that imparts strong sweetness to Matcha tea is disclosed by a method including the first, second, and third steps as follows. In the first step, in order to extract aroma components contained in high-grade tea leaves, matcha Slurry is m...
