[Industrial Application Field] The present invention relates to a health tea that can be used as a recreational food or a health food, and specifically relates to a novel health tea using Gymnema sylvestre. [Summary of the Invention] The present invention aims to provide a healthy tea with excellent physiological effects and excellent taste by mixing dried leaf powder of Gymnema sylvestre with matcha. [Prior art] Gymnema Sylvestre,
Hereinafter, it will simply be referred to as gymnema. ) is a climbing plant of the Asclepiadaceae family that grows in tropical regions such as India, Southeast Asia, southern China, and Africa, and its dried leaves have been used as a crude drug for diabetes in India for 2,000 years. is recorded. Furthermore, this plant is said to be effective for stomach health, tonicity, diuresis, bowel movements, etc., and research is underway.
For example, Yonago Medical Journal, Vol. 38, No. 2, p. 127~
Pages 137 and 138 to 145 show that an oral test using rats showed that Gymnema suppressed the rise in blood sugar levels in response to a glucose load, and that Streptococcus miutans, which causes dental caries,
It has been reported that it has a remarkable effect on suppressing insoluble glucan production in S. mutans). Therefore, it is thought that excellent health foods can be provided by utilizing the physiological effects of gymnema, but gymnemic acid contained in the extract of dried leaves of gymnema has a sweet taste suppressing effect. Furthermore, it has a strong bitter and astringent taste, so it has been difficult to apply it to foods despite its high physiological effects. That is, the above gymnemic acid is
It acts on the sweet taste receptors in taste cells and prevents the binding between sweet substances and sweet taste receptors, and as a result, after the gymnema component comes into contact with the tongue, the sweet taste completely disappears for several tens of minutes. [Problems to be solved by the invention] The present invention was proposed in view of the above-mentioned conventional situation, and aims to effectively utilize Gymnema sylvestre, which has excellent physiological effects and exhibits The purpose is to provide healthy tea with excellent taste. [Means for solving the problem] In order to apply gymnema, which has such various physiological effects, to foods, the present inventors conducted tests on the compatibility of gymnema with various foods, and found that green tea It was found that it is particularly well suited for matcha in terms of taste. The present invention was completed based on this knowledge, and is characterized by mixing gymnema sylvestre powder and matcha. The gymnema sylvestre powder (hereinafter simply referred to as gymnema powder) used in the present invention is:
It is made from crushed dried leaves of Gymnema, a climbing plant. Therefore, for example, dry leaves of Gymnema are put into a roaster, roasted while rotating, cooled to room temperature, foreign substances such as stems are removed, and the mixture is easily prepared by passing it through a grinder. be able to. The size of gymnema powder obtained by crushing is
It may be set as appropriate depending on the intended use, but for example, in the case of drinking, one that can pass through a 100-mesh Tyler standard sieve is used. When roasting is performed at a relatively low roasting temperature, a powder with excellent green color and light blue color can be obtained, but if the temperature is too low, a grassy odor remains.
On the other hand, when processed under relatively high temperature conditions, the color and light blue will decrease and the color will approach brown, but the aroma and flavor will be improved and it will become more compatible with the aroma and flavor of green tea. Furthermore, the higher the roasting temperature, the greater the physiological effects of the extract. However, if the roasting temperature is too high, the active ingredients in gymnema may be lost. Therefore, the practical roasting temperature is between 100 and 250.
The temperature is preferably 120 to 200°C, more preferably 120 to 200°C. Roasting time is about 10 to 40 minutes,
Preferably it is 15 to 20 minutes. If the roasting time is too long, it is pointless and production efficiency will decrease. The above gymnema powder is mixed with matcha to make a health tea, and the ratio of gymnema powder to be mixed is preferably 5 to 40% based on the total solid weight. If you drink it within the above-mentioned range, you can enjoy the same taste as matcha, and if you set the roasting temperature and roasting time of gymnema leaves appropriately, you can obtain a product that is sensually equivalent to matcha. In particular, when flavor and nourishment are the main ingredients, it is preferable to reduce the mixing ratio of gymnema powder as appropriate, and when physiological effects are the main ingredient, it is preferable to increase the mixing ratio of gymnema powder as appropriate. However, if the proportion of gymnema powder is too large, problems will arise in terms of taste, so it is still preferable to keep it within the above range. The above-mentioned health teas are not only useful as health teas for general consumers, but if used as various food additives, they can be used in conjunction with green tea's nutritional components, color, and palatability to develop effective health foods. applicable. [Action] Add dried Gymnema leaves or Gymnema extract to sugar, candy, bean paste, and tiyocolate, each at a concentration of 10 to 20% (0.5% in the case of Gymnema extract) based on the solid weight.
~2.0%) When the product was mixed and sampled, a bitter and astringent taste remained in the mouth, and in the case of a highly concentrated product, the sensation of sweetness disappeared for 30 minutes after tasting. On the other hand, when mixed with matcha at the same ratio as above and sampled, the sensory characteristics of matcha were not lost, and the sweetness was less likely to disappear after drinking the tea. That is, by mixing gymnema with high physiological effects, which could not be applied to conventional foods, it becomes possible to provide it for drinking or eating as a gymnema-containing food with improved taste by mixing it with matcha. Matcha is usually drunk with sugar-based dried sweets, Japanese sweets, etc. to enhance its flavor.
Furthermore, when mixed in various food fields (Japanese and Western confectionery, frozen desserts, beverages, paste products, etc.), they are used in combination with large amounts of carbohydrates. However, in recent years, the number of people who have to limit their intake of sweets has been increasing, and as a result, demand for matcha, which has high nutritional value and is highly useful as a luxury item, is currently being restricted. . From this point of view, it can be said that the combined use of matcha and gymnema powder, which has a high physiological effect on carbohydrates, is of great significance. [Examples] The present invention will be described below based on specific examples. Example 1 First, 500g of dried leaves of Gymnema Sylvester from Madras, India were placed in a roasting machine and roasted while rotating.
The mixture was roasted at 200°C for 15 minutes, immediately spread on a vat, left for 1 hour, and cooled to room temperature. Next, the mixture was pulverized for 30 minutes using a Vibromill (manufactured by Yaskawa Electric Co., Ltd.), and passed through a 100-mesh Tyler standard sieve to obtain Gymnema Sylvester powder. Next, this gymnema sylvestre powder was mixed with a commercially available powder (manufactured by Aoi Seicha Co., Ltd., trade name: Haruka no Machi) using a mixer, and the mixture was mixed with 10%, 20%, and 20%, respectively, based on the solid weight.
Four types of health tea were prepared with a mixing ratio of 40% and 60% gymnema sylvestre powder. The following sensory tests were conducted on these samples. The test items were the following four items, and the average value was calculated using a 5-point evaluation method using the raw matcha as a standard by 10 panelists. Test items Color and luster: Color and luster of healthy tea powder Light blue: Add 2g of healthy tea to 80ml of 90℃ warm water and mix with a chasen in the usual manner. Foaming and light blue of tea liquid.Fragrance: Contains the same tea liquid. Aroma and Nourishing Taste: Nourishing taste when containing the same tea liquid.Furthermore, the gymnema taste and aftertaste were also investigated. Gymnema taste is based on Gymnema Sylvester powder, and each gymnema taste (mainly bitterness and gymnema odor) is evaluated on 5 points. Aftertaste was a study of the change in taste after drinking tea. Commercially available yokan was chewed before and after drinking tea, and the degree of sweetness detected and the change in the taste quality of the yokan were evaluated on a 5-point scale. In addition, this test was conducted every 2 hours because the effect of gymnema on taste cells after drinking tea might interfere with the subsequent sensory test. The results are shown in Table 1.
