グリーンアスパラガスを使用した。DETAILED DESCRIPTION OF THE INVENTION O-157 of asparagus extract
The following experiment was conducted in order to examine the bactericidal effect on the bacteria. O
The measuring method of -157 was carried out according to the test method of pathogenic Escherichia coli O-157 shown in FIG. In addition, edible green asparagus was used as asparagus.

の菌数を測定した。<Example 1> A general-purpose food which is said to have a bactericidal effect is minced, ground, and diluted with ion-exchanged water to a concentration of 1.0 and 10% (by weight) to prepare samples. After diluting O-157 into the solution, room temperature (25 ° C)
For 24 and 48 hours, and cultured at 35 ° C. for 24 hours using a delicoxylate medium.
Was measured.
【表1】 このように、アスパラガスにおいて107オーダーのO
−157が50にまで殺菌され、アスパラガスに明らか
に殺菌作用があることが確認された。[Table 1] Thus, asparagus has 10 7 orders of O
-157 was sterilized to 50, and it was confirmed that asparagus had a clear bactericidal action.

菌数を測定した。<Example 2> In order to further clarify the bactericidal action of asparagus, according to Example 1, samples were prepared by diluting the asparagus concentration to 1.0, 5, 10% (by weight). , This sample is extracted under different temperature conditions,
The supernatant was pulverized with O-157 in the same manner as in Example 1,
The number of bacteria was measured.
【表2】 このように、アスパラガスの抽出温度が80℃以上であ

た、アスパラガスの濃度が5%(重量)以上でないとO
−157への殺菌作用は発生しない。ただし、アスパラ
ガスの濃度が5%(重量)のときには、抽出温度が60
℃ではO−157への殺菌作用は薄くなる。[Table 2] Thus, if the asparagus extraction temperature is 80 ° C. or higher, there is no germicidal action on O-157. Also, if the concentration of asparagus is not more than 5% (weight), O
No germicidal action on -157 occurs. However, when the asparagus concentration is 5% (weight), the extraction temperature is 60%.
At 0 C, the bactericidal action on O-157 is weak.
【0015】尚、アスパラガスの濃度が10%(重量)

不明であるが、アスパラガスの濃度が高くなるにつれて
殺菌効果も高まるため、10%(重量)より高い場合に
おいても十分な殺菌効果を得られるものと推測される。The concentration of asparagus is 10% (weight)
It is unknown at this time whether the bactericidal action occurs at higher levels, but it is speculated that sufficient bactericidal effects can be obtained even at higher than 10% (weight) because the bactericidal effect increases as the concentration of asparagus increases. Is done.
【0016】実施例1,2の結果よりアスパラガスの殺
菌成分を考察する。The sterilization components of asparagus will be considered from the results of Examples 1 and 2.

7,3',4'−テトラヒドロキシフラバノールー3)に
起因するといわれている。In the health life business 108 (1996) reported by Shimamura et al. At Showa University, O-15 was added to green tea.
7 has been reported to have an antibacterial effect, and this effect is attributed to catechin (C 15 H 14 O 6 : 5) which is astringent component of green tea.

キンの抗菌作用を補助する役目を果たす耐熱性の低い成
分により具現化するものと考えられる。Catechin is also contained in asparagus, but catechin is not a substance that decomposes at 80 ° C. (melting point of (+)-catechin which is catechin is 13
2 ° C., the melting point of (−)-epicatechin is 245 ° C.,
Catechin has excellent heat resistance. Therefore, it is considered that the bactericidal action of asparagus is embodied by a component other than catechin or a component having low heat resistance which serves to assist the antibacterial action of catechin.

考えられる。On the other hand, the sterilizing component of asparagus has a sterilizing effect only when the concentration of asparagus is less than 5% (weight). This is because the concentration of asparagus is too low and the number of O- It is probable that 157 could not be sterilized.
【0020】また、アスパラガスの殺菌成分は熱に弱い
ことから、80℃以上では分解してしまうか、変成して
しまうものと考えられる。Further, the sterilizing component of asparagus is considered to be decomposed or denatured at 80 ° C. or higher because it is weak to heat.

菌効果の強さは、107オーダーのO−157を48時
間で10以下にまで殺菌する極めて強力なものである。To summarize the results of the above examples, asparagus contains a component having a strong bactericidal action against pathogenic Escherichia coli O-157. Its sterilizing effect is extremely strong in sterilizing O-157 on the order of 10 7 to 10 or less in 48 hours.

用することができる。The germicidal component of asparagus can be extracted with water at an extraction temperature of less than 80 ° C. Therefore, in producing the asparagus extract, only water may be used, and the extract can be safely used as a bactericide for natural products.
【0023】 アスパラガスの殺菌成分は、アスパラ
ガスの濃度が5%(重量)以上においてO−157への
殺菌作用が発生する。Aseptic components of asparagus have a disinfecting effect on O-157 when the concentration of asparagus is 5% (by weight) or more.
