この発明は、ギムネマ・シルベスタ葉又はそのエキスの
苦味・渋味除去方法およびその飲用物に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for removing bitterness and astringency from Gymnema sylvestre leaves or extracts thereof, and drinks thereof.
（従来の技術）
従来、ギムネマ・シルベスタ葉からの注出物は、糖の吸
収を阻害する効力があるので、糖尿病の治療又は予防に
有効であることが知られていた。(Prior Art) It has been known that an infusion from Gymnema sylvestre leaves is effective in treating or preventing diabetes because it has the effect of inhibiting sugar absorption.
また、ギムネマ・シルベスタ葉のエキスの苦味・渋味除
去方法も提案されていた（特開平１−１０２０２８号）
。Additionally, a method for removing the bitterness and astringency of Gymnema sylvestre leaf extract was proposed (Japanese Patent Application Laid-Open No. 102028/1999).
.
（発明により解決すべき課題）
従来、ギムネマ・シルベスタは糖の抑制効果が知られて
おり、長期継続的な飲用が糖尿病の予防又は治療に有用
とされていたか、苦味又は渋味の為に飲用に供し得ない
問題点かあった。(Problems to be solved by the invention) Previously, Gymnema sylvestre was known to have a sugar suppressing effect, and long-term continuous drinking was thought to be useful for the prevention or treatment of diabetes, or because of its bitter or astringent taste. There were some problems that made it impossible to provide this service.
そこで前記のようにギムネマ・シルベスタ葉のエキスに
澱粉質の存在下てα−グルコシル転移酵素を作用させ、
前記エキス中に含まれる配糖体類をα−グルコシル化す
ることにより、エキスの苦味・渋味を除去する技術が提
案されている。Therefore, as mentioned above, α-glucosyltransferase was applied to Gymnema sylvestre leaf extract in the presence of starch,
A technique has been proposed for removing the bitterness and astringency of the extract by α-glucosylating the glycosides contained in the extract.
然し乍ら、前記α−グルコシル化された成分は日中に入
れると急速にもとに戻り、苦味・渋味か出てくるので、
錠剤として服用するには支障が少ないが、通常用いる茶
の代用として常時の飲用物としては不適当であるという
問題点があった。However, if the α-glucosylated ingredients are added during the day, they will quickly return to their original state and produce a bitter or astringent taste.
Although there are few problems when taken as a tablet, there is a problem in that it is unsuitable as a regular drink as a substitute for tea that is normally used.
（課題を解決する為の手段）
然るにこの発明は、キトサンにギムネマ・シルベスタの
苦味・渋味を有効にマスキングする特性かあるのを利用
し、前記従来の問題点を解決し、ギムネマ・シルベスタ
を常時飲用物とすることに成功したのである。(Means for Solving the Problems) However, the present invention solves the conventional problems by utilizing the fact that chitosan has the property of effectively masking the bitterness and astringency of Gymnema sylvestre. They succeeded in making it a constant drink.
即ち方法の発明は、ギムネマ・シルベスタ葉の乾燥裁断
物に、その０．５％〜１０％のキトサン粉末を加えて均
一混合物とすることを特徴としたギムネマ・シルベスタ
の苦味・渋味除去方法である。That is, the method invention is a method for removing the bitterness and astringency of Gymnema sylvestre, which is characterized by adding 0.5% to 10% of chitosan powder to dried cut leaves of Gymnema sylvestre to form a homogeneous mixture. be.
また、ギムネマ・シルベスタ葉に、その０．５％〜ｌＯ
％のキトサン液を噴霧し、これを乾燥することを特徴と

。In addition, 0.5% to 1O of Gymnema sylvestre leaves
This is a method for removing the bitterness and astringency of Gymnema sylvestre, which is characterized by spraying % of chitosan liquid and drying it.
次に物の発明は、ギムネマ・シルベスタ葉と、その０．
５％〜１０％のキトサン粉末との混合物を所定量宛透水
袋に包装したことを特徴とするギムネマ・シルベスタの
飲用物である。また、ギムネマ・シルベスタ葉のエキス
に、その０．５％〜１０％のキトサン液を混合してなる
ギムネマ・シルベスタ飲用物である。The next invention was Gymnema sylvestre leaves and their 0.
This is a drinkable product of Gymnema sylvestre characterized by packaging a mixture with 5% to 10% chitosan powder in a water-permeable bag for a predetermined amount. Moreover, it is a Gymnema sylvestre drink made by mixing Gymnema sylvestre leaf extract with 0.5% to 10% of chitosan liquid.
前記キトサンによるマスキング効果は、ＰＨ４，０前後

スキングが解除され、ギムネマ酸本来の働きを取り戻し
て腸内へ入る。そこで糖の吸収を抑制するものと考えら
れる。The masking effect of chitosan is canceled at around pH 4.0. Therefore, according to this invention, when a drink that has been masked with chitosan enters the stomach, the masking is canceled by stomach acid, and the original function of gymnemic acid is restored and the drink enters the intestine. Therefore, it is thought to suppress sugar absorption.
即ちギムネマ酸本来の効果を損うことなく、経口時に苦
味・渋味がなく、服用後直ちに有効に働くという理想的
処理ができたのである。従って、通常のお茶と同様に常
時飲用物として使用することができるので、薬用の観念
なく、お茶として用い、しかも制糖効果を奏する点が優
れている。In other words, an ideal treatment has been achieved that does not impair the original effects of gymnemic acid, has no bitter or astringent taste when taken orally, and is effective immediately after administration. Therefore, it can be used as a regular drink like regular tea, so it can be used as a tea without any medicinal purpose, and it is excellent in that it has an anti-sugar effect.
前記においてキトサンの添加量を０．５％以下にすると
、マスキング効果が急速に低下し、常時服用に適さない
ものと認められる。また、１０％以上にしてもマスキン
グ効果は変化しないので、いわゆる余剰となるので１０
％以下が好ましい。In the above, if the amount of chitosan added is 0.5% or less, the masking effect will rapidly decrease, making it unsuitable for regular administration. Also, since the masking effect does not change even if it is increased to 10% or more, it becomes a so-called surplus.
% or less is preferable.
キトサンの添加量については、嗜好との関係で一概に決
めることはてきないが、苦味・渋味の為に苦痛を感じな
い程度として１％〜５％が一般的であろう。The amount of chitosan to be added cannot be determined unconditionally due to preference, but 1% to 5% is generally considered to be an amount that does not cause discomfort due to bitterness and astringency.

・渋味に対してもマスキング効果を奏することがわかっ
た。In the chitosan mentioned above, D-glucosamine obtained by deacetylating natural polymer chitin is β-(1-4
) is a type of bound mukota sugar. While chitin has strong intramolecular hydrogen bonds and poor reactivity, chitosan easily dissolves in dilute acids such as organic acids and mineral acids. Chitosan exists in large quantities in nature as a component of the outer shell of crustaceans and insects, and is one of the few polymers that has a highly reactive amino group and two hydroxyl groups in its molecule, making it a particulate porous material. It was found that it is useful as various immobilization carriers or adsorption carriers, and also has a masking effect on the bitterness and astringency of Gymnema sylvestre.
キトサンは中性からアルカリ性に対しては安定性がある

るおそれはない。Chitosan is stable in neutral to alkaline conditions, but dissolves in acids with a pH of 5.8 to 6.0 or less. Chitosan is also resistant to heat at 121°C for 15 minutes (
It can withstand high-pressure steam sterilization (high-pressure steam sterilization), so there is no risk of the Maskink effect decreasing even if it is placed in boiling water with Gymnema sylvestre leaves.
（作 用）
この発明は、ギムネマ・シルベスタ葉又はそのエキスに
適量のキトサンを混入し、又は付着させるので、ギムネ
マ酸特有の苦味・渋味をマスキングすることができる。(Function) This invention mixes or attaches an appropriate amount of chitosan to Gymnema sylvestre leaves or its extract, so that the bitterness and astringency peculiar to gymnemic acid can be masked.
またこのマスキングは服用後、胃内で解除される特性が
ある。Additionally, this masking has the property of being released within the stomach after taking the drug.
