【産業上の利用分野】
本発明は、アロエ緑色廃棄物の再利用(リサイクリング)としても有用なアロエ緑色廃棄物から得られた食餌繊維の新しい用途に係り、より詳しくは、アロエ緑色廃棄物から得られた食餌繊維をビフィダス菌の成長を促進させるための組成物として利用したビフィダス菌成長促進用組成物に関する。
【0002】
【従来の技術】
アロエは、虫に刺された時、火傷の時、消化器官の異常の時等における治療剤として、あるいは、緩下剤(laxative)として最も長く愛用されてきた薬用植物の一つである。そして、最近では、キャンディ、ジェリー、ジュース等の飲食物に添加する食用添加剤として、また、生理的効能をもつ成分として化粧品の添加剤としても広く用いられるようになっている。
【0003】
アロエは、その種類がおよそ350にも達するが、実際にはアロエヴェラ(Aloe vera )とアロエアボレセンス(Aloe aborescence)だけが広範に利用されている。
アロエアボレセンスは、葉全体が活用されるので廃棄物がほとんどない。しかしながら、アロエヴェラについては、99.5%が水分である内部のゲル成分だけが利用されており、このゲル成分は水を含むとき葉全体の重さの50%を占めるが、乾燥された場合には10%を占めるのみである。
【0004】
このように、アロエヴェラは、その内部の柔組織ゲル(parenchyma gel)だけが利用されているので、残りの部分は農業廃棄物として廃棄されている。以下、アロエヴェラを主とするアロエからその柔組織ゲル部分を採取した残りの廃棄物部分をアロエ緑色廃棄物という。
そして、このアロエ緑色廃棄物は、アロエヴェラの場合は乾燥時にその葉全体の重量の90%を占め、また、微生物の成長を抑制する成分を含んでいるので容易には腐敗しない。
【0005】
ところで、食餌繊維は、それが水を吸収した時、元々の体積の1,000倍以上にも膨潤し、陽イオンや、炭素数の少ない低級脂肪酸や、胆汁酸を吸着し、大便の体積を増し、そして、その腸内滞留時間を長くするので、胃腸障害を治療することができ、また、脂血症(lipidemia )、糖血症(glycemia)、直腸癌(rectal cancer )等を予防すると報告されている。
【0006】
トゥローウェル(Trouwell)が食餌繊維の摂取量と老人性疾病との相関関係を発表して以来、米国の癌研究所(Cancer Research Institute )では毎日10〜15g以上、あるいは、20〜30gまで摂取するよう奨励しており、かくして食餌繊維製品が競争して開発されている。
【0007】
ここで、食餌繊維とは、人間又は動物由来の消化酵素によっては分解されない「耐性炭水化物(resistant carbohydrate)」であり、キシラン(xylans)、マンナン(mannans )、ガラクタン(galactans )及びベータグルカン(β−glucans)等のようなセルロース、リグニン(lignins )、ペクチン(pectins )、ゴム(gums)や藻類(algae )から誘導される硫化ガラクタン(sulfated galactans)、マンヌロナン(mannuronans )の如き生体抽出物等を含み、更に、人工的に合成されたセルロースのエーテル又はエステルを含むものである。これらのうち、水溶性食餌繊維は液状製品に適用することが可能であり、また、不溶性食餌繊維はヨーグルトのような不透明液状製品やパン、菓子のような固体製品に適用することができる。
【0008】
砂糖黍のパルプ、オレンジパルプ(orange pulp )のような果物のパルプ、穀物の種子の外皮、あるいはその他の農業廃棄物から食餌繊維を抽出するために、多くの試みがなされてきた。農業廃棄物をリサイクルしようとするこれらの試みは、これらの廃棄物によって生じる汚染公害を解決するという視点から、意義のあることである。
【0009】
【発明が解決しようとする課題】
かかる観点に鑑みて、本発明者は、柔組織ゲル成分抽出後のアロエ緑色廃棄物について鋭意研究を重ねた結果、このアロエ緑色廃棄物には極めて多量の食餌繊維が含まれていることを見出し、また、このアロエ緑色廃棄物から得られた食餌繊維がビフィダス菌の成長を大いに促進する能力を有することを見出し、本発明を完成した。
【0010】
従って、本発明の目的は、アロエから柔組織ゲル成分を採取した後のアロエ緑色廃棄物から得られた食餌繊維の新しい用途を提供することにある。
また、本発明の他の目的は、このようなアロエ緑色廃棄物から得られた食餌繊維を含有するビフィダス菌成長促進用組成物を提供するにある。
【0011】
すなわち、本発明は、アロエ緑色廃棄物から得られた食餌繊維を含有するビフィダス菌成長促進用組成物である。そして、上記アロエ緑色廃棄物がアロエヴェラ緑色廃棄物であるビフィダス菌成長促進用組成物であり、また、上記食餌繊維が水溶性食餌繊維であるビフィダス菌成長促進用組成物である。
【0012】
先ず、食餌繊維の定量法を本発明で使用した方法によって説明する。
方法1:食餌繊維の総量測定法(AOAC 1985, by Asso. Off. Agric. Chem. )秤量したサンプルを、手順によってサーマミル〔thermamyl 、ノボ(Novo)社製〕、プロテアーゼ(protease)及びグルコアミーラゼ(glucoamylase)等で分解し、それから濾過される。濾過されたものは乾燥され、その重さが測定される。この物質は燃焼され、そして、その灰分の重量が測定される。サンプルの元々の重量に対する灰分の重量の比率(%)が計算される。食餌繊維の総量は、この方法によって測定することができる。
【0013】
方法2:サウスゲイド変法(modified Southgate method )によるSDF(水溶性食餌繊維)、NC(非セルロース食餌繊維)及びCD(セルロー
ス性食餌繊維)の分別法
乾燥、脱脂されたサンプル1gをサーマミル、プロテアーゼ、及びグルコアミラーゼで逐次加水分解した後、塩水、1N硫酸及び72%硫酸で順次抽出する。このようにして得られたものを3つのグループに分類する。すなわち、塩水で抽出して得られた水溶性食餌繊維(SDF)、残存物を1N硫酸で抽出して得られた非セルロース性食餌繊維(NC)、及び更にその残存物を72%硫酸で抽出して得られたセルロース性食餌繊維(CD)である。
【0014】
それぞれの食餌繊維の重さを測定する。元の1gのサンプルから各灰分の重さを除いた部分がリグニン(lignin)に当たる。この方法によってそれぞれ異なる食餌繊維の含有量を測定することができる。
【0015】
六炭糖(hexose)、ウロン酸(uronic acid )及び五炭糖(pentose )に対する定量法は日本食品衛生法(Japanese Food Sanitation Act)の食品成分分析法(Analysis of components of food)に従った。
【0016】
上述したように、本発明の第二の目的は、アロエ緑色廃棄物の食餌繊維がビフィダス菌の成長を促進する効能を有するという発見に基づいて、アロエ緑色廃棄物から抽出された食餌繊維を含有するビフィダス菌成長促進用組成物を提供することにある。
【0017】
そして、この組成物がビフィダス菌の成長を促進する効能を測定するため、改良された和田の方法(Wada et al.,日本栄養−食料学会誌44, p171, 1991)を用いた。
【0018】
アロエ緑色廃棄物(アロエ皮)から食餌繊維を抽出する方法には種々あり、本発明の実施例による抽出方法に限定されるものではない。

[Industrial applications]
The present invention relates to a new use of dietary fiber obtained from aloe green waste which is also useful as recycling of aloe green waste. More specifically, the present invention relates to the use of dietary fiber obtained from aloe green waste. The present invention relates to a composition for promoting the growth of bifidobacteria, which is used as a composition for promoting the growth of bifidobacteria.
[0002]
[Prior art]
Aloe is one of the medicinal plants that has long been used as a remedy for insect bites, burns, digestive organ abnormalities, etc., or as a laxative. Recently, it has been widely used as an edible additive to be added to foods and drinks such as candy, jelly, juice and the like, and also as a cosmetic additive as a component having a physiological effect.
[0003]
Aloe, which is about 350 in kind, is actually widely used only in Aloe vera and Aloe aboresence.
Aloair Bolesens uses almost all of the leaves, so there is little waste. However, for Aloe Vera, only the inner gel component, which is 99.5% water, is utilized, which occupies 50% of the weight of the whole leaf when containing water, but when dried, Occupies only 10%.
[0004]
In this way, Aloe Vera uses only the parenchyma gel inside the Aloe Vera, and the remaining part is discarded as agricultural waste. Hereinafter, the remaining waste portion obtained by collecting the soft tissue gel portion from aloe mainly composed of aloe vera is referred to as aloe green waste.
In the case of aloe vera, this aloe green waste occupies 90% of the weight of the whole leaf when dried, and does not easily rot because it contains a component that suppresses the growth of microorganisms.
[0005]
By the way, dietary fiber, when it absorbs water, swells to more than 1,000 times its original volume, adsorbs cations, lower fatty acids with few carbon atoms, and bile acids, and reduces the volume of feces. It increases the intestinal residence time and can treat gastrointestinal disorders, and also reports prevention of lipidemia, glycemia, rectal cancer, etc. Have been.
[0006]
Since Trouwell has announced a correlation between dietary fiber intake and geriatric disease, the Cancer Research Institute in the United States consumes more than 10-15 g, or up to 20-30 g daily. And dietary fiber products are being developed in competition.
[0007]
Here, the dietary fiber is a “resistant carbohydrate” that is not decomposed by digestive enzymes derived from humans or animals, and is xylan, mannans, galactans, and beta-glucan (β-). glucans, etc .; and biological extracts such as lignins, pectins, gums and algae (algae) derived from sulphated galactans, mannuronans, and mannuronans. And artificially synthesized cellulose ethers or esters. Among these, water-soluble dietary fiber can be applied to liquid products, and insoluble dietary fiber can be applied to opaque liquid products such as yogurt and solid products such as bread and confectionery.
[0008]
Many attempts have been made to extract dietary fiber from sugar cane pulp, fruit pulp such as orange pulp, cereal seed hulls, or other agricultural waste. These attempts to recycle agricultural waste are significant in terms of resolving the pollution caused by these wastes.
[0009]
[Problems to be solved by the invention]
In view of such a viewpoint, the present inventors have conducted intensive studies on aloe green waste after extracting soft tissue gel components, and as a result, have found that this aloe green waste contains an extremely large amount of dietary fiber. Also, they have found that dietary fiber obtained from this aloe green waste has the ability to greatly promote the growth of bifidobacteria, and completed the present invention.
[0010]
Accordingly, it is an object of the present invention to provide a new use of dietary fiber obtained from aloe green waste after harvesting the soft tissue gel component from aloe.
It is another object of the present invention to provide a composition for promoting the growth of bifidobacteria containing dietary fiber obtained from such aloe green waste.
[0011]
That is, the present invention is a composition for promoting the growth of bifidobacteria comprising dietary fiber obtained from aloe green waste. The aloe green waste is a bifidobacterium growth promoting composition that is aloe vera green waste, and the dietary fiber is a bifidobacterium growth promoting composition that is a water-soluble dietary fiber.
[0012]
First, a method for quantifying dietary fiber will be described by the method used in the present invention.
Method 1: A method of measuring the total amount of dietary fiber (AOAC 1985, by Asso. Off. Agric. Chem.). ) And then filtered. The filtered product is dried and its weight is measured. This material is burned and its ash is weighed. The ratio (%) of the ash weight to the original weight of the sample is calculated. The total amount of dietary fiber can be measured by this method.
[0013]
Method 2: Differentiated method of SDF (water-soluble dietary fiber), NC (non-cellulose dietary fiber) and CD (cellulose dietary fiber) by modified Southgate method. And glucoamylase, and then sequentially extracted with brine, 1N sulfuric acid and 72% sulfuric acid. Those obtained in this way are classified into three groups. That is, the water-soluble dietary fiber (SDF) obtained by extracting with salt water, the non-cellulosic dietary fiber (NC) obtained by extracting the residue with 1N sulfuric acid, and further extracting the residue with 72% sulfuric acid. It is a cellulosic dietary fiber (CD) obtained by the following method.
[0014]
The weight of each dietary fiber is measured. The portion excluding the weight of each ash from the original 1 g sample corresponds to lignin. By this method, the content of different dietary fibers can be measured.
[0015]
Hexose, uronic acid, and pentose were quantified in accordance with the Analysis of Components of Foods Act of the Japan Food Sanitation Act.
[0016]
As mentioned above, a second object of the present invention is to contain dietary fiber extracted from aloe green waste based on the discovery that the dietary fiber of aloe green waste has the ability to promote the growth of bifidobacteria. To provide a composition for promoting the growth of bifidobacteria.
[0017]
In order to determine the effect of this composition on promoting the growth of bifidobacteria, an improved method of Wada (Wada et al., Journal of Japanese Society of Nutrition and Food Science 44, p171, 1991) was used.
[0018]
There are various methods for extracting dietary fiber from aloe green waste (aloe skin), and the method is not limited to the extraction method according to the embodiment of the present invention.
A feature of the present invention is to utilize aloe green waste as a source of dietary fiber, and a known method for extracting dietary fiber from aloe green waste can be employed. The extracted dietary fiber can be divided into two groups: water-soluble dietary fiber and insoluble dietary fiber.
[0019]
Water-soluble dietary fiber is used for transparent products such as drinks, and insoluble dietary fiber is used for all products to which dietary fiber can be added, such as yogurt, bread and confectionery. The amount added depends on the type of the product, the purpose of use, the production method, and the like, and can be easily selected by those skilled in the art.
[0020]
Generally, the amount of dietary fiber added can be appropriately selected within the range of 0.01 to 99% by weight, and is preferably 0.1 to 50% by weight.
In addition, not only aloe green waste but also dietary fiber extracted from other materials also has the effect of promoting the growth of bifidobacteria.
[0021]
