Helicobacter pylori의 생육과 각종 유기산의 식품 보존료로서의 효과

Abstract

Helicobacter pylori의 생육과 각종 유기산의 식품보존료로서의 효과를 검토하였다. 우선 보존료로 현재 식품첨가물로 사용되고 있는 소르빈산(sorbic acid), 프로피온산(propionic), 안식향산(benzoic acid) 등의 H. pylori에 대한 항균능력을 검토한 결과 소르빈산, 프로피온산, 안식향산의 H. pylori에 대한 항균효과가 관찰되었으며 안식향산은 소르빈산이나 프로피온산과 비교했을 때는 별로 큰 효과를 나타내지 못하였다. 보존료의 조합에 대한 H. pylori의 생육억제효과는 0.5% 소르빈산과 0.5% 프로피온산을 조합하는 경우 나타났으며 다른 조합군과 비교할 때 큰 차이를 나타내지 못하였다. 유기산과 H. pylori의 생육관계에서는 단독 첨가시에는 항균력이 크게 나타나지 않고 조합하는 경우에만 좋은 항균력을 나타내었다. 유기산, 보존료와 H. pylori 생육관계는 유기산류는 어떤 보존료와 혼합하여도 항균력에 상승효과가 있는 것으로 나타났다. 특히 ?맙Щ遠? 경우 소르빈산과 조합한 경우에는 H. pylori생육이 많이 억제되었으며 그 다음이 구연산+안식향산, 구연산+프로피온산 순으로 균에 대한 항균력이 감소되었다. 또 사과산과 숙실산은 구연산과 비슷한 경향을 나타내었다.

The purpose of this study was to examine the effect of various organic acids as food preservatives on the growth of Helicobacter pylori(H.pylor). The antimicrobial effects of sorbic acid, propionic acid and benzoic acid currently used as food preservatives were examined in light of the growth of Helicobacter pylori. Each of them was observed to have positive antimicrobial effect on Helicobacter pylori. However, benzoic acid wasn't higher than sorbic acid and propionic acid in antimicrobial effect. As for the combination of preservatives, antimicrobial activity of H. pylori was shown in the combination of sorbic acid(0.5%) and propionic acid(0.5%). However, its effect was not significantly different in comparison with other combinations. In the relationship of organic acids and H. pylori's growth, organic acid had no effect on antimicrobial activity when it was used alone, whereas antimicrobial effect was shown to be better in case of combination. If intermix of organic acids and preservatives and addition to the medium for suppression of H. pylori growth were achieved, organic acid exhibited synergistic effect on suppression of H. pylori's growth, even in combination of any other preservatives. In particular, in combination of citric acid and sorbic acid, the growth of H. pylori was shown to be remarkable suppression. And the effectiveness on suppression of H. pylori's growth was lowered in order of citric acid + bezoic acid and citric acid + propionic. acid. It was also found that the antimicrobial effects of malic acid and succinic acid were similar to those of citric acid.
