Description

殺菌又は静菌用液状組成物Liquid composition for bactericidal or bacteriostatic
　本発明は、殺菌又は静菌用組成物に関する。 The present invention relates to a bactericidal or bacteriostatic composition.
　従来、食品製造においては、微生物の増殖による食品の腐敗や変質を防ぐための組成物が使用されている。特許文献１には、脂肪酸モノエステル、酸またはキレート化剤、食品グレードの界面活性剤及び媒体を含有する食品用殺菌剤組成物が記載されている。特許文献２には、フィチン酸及び乳化剤を含有する乳入り飲料用乳化安定剤が記載されている。特許文献３には、ホースラディッシュ由来の抗菌性物質と、有機酸又はその塩、アミノ酸、低級脂肪酸エステル、シュガーエステル、ビタミンＢ１エステル、重合リン酸塩、フィチン酸、エタノール等から選択される１種又は２種以上とを含有する食品用保存剤が記載されている。特許文献４には、エタノール、グルコン酸ナトリウム、カプリン酸、カプリル酸モノグリセリド及びカプリン酸モノグリセリド、ｐＨ調整剤、水を含有し、水溶液の酸度が０．１～０．９である殺菌剤組成物が記載されている。 Conventionally, in food production, compositions for preventing food spoilage and alteration due to the growth of microorganisms have been used. Patent Document 1 describes a food disinfectant composition containing a fatty acid monoester, an acid or chelating agent, a food grade surfactant and a medium. Patent Document 2 describes an emulsion stabilizer for a beverage containing milk containing phytic acid and an emulsifier. Patent Document 3 discloses an antibacterial substance derived from horseradish, an organic acid or a salt thereof, an amino acid, a lower fatty acid ester, a sugar ester, a vitamin B1 ester, a polymerized phosphate, phytic acid, ethanol, and the like.

　食品、又はそれを取り扱う機器もしくはそれが存在する環境の殺菌又は静菌のための組成物においては、その殺菌又は静菌効果が重要であるだけでなく、安全性も無視できない。一方で、食品分野で微生物の増殖制御に従来使用されている組成物は、安全性の基準は満たすが、水溶性が低く均質な液状とすることが難しいため、機器等の洗浄や殺菌には使いづらいことが多い。したがって、均質な液状を呈し、高い殺菌又は静菌効果を有しながらも生体に対する安全性は高く、食品、又はそれを取り扱う機器もしくはそれが存在する環境の殺菌又は静菌に有用な組成物が求められている。 In the composition for sterilization or bacteriostasis of food or the equipment that handles it or the environment in which it exists, not only the bactericidal or bacteriostatic effect is important, but also the safety cannot be ignored. On the other hand, compositions that have been used in the field of food to control the growth of microorganisms meet the safety standards, but are difficult to form a homogeneous liquid with low water solubility. Often difficult to use. Therefore, a composition that is homogeneous liquid, has high sterilization or bacteriostatic effect and is highly safe for living organisms, and is useful for sterilization or bacteriostasis of food or the equipment in which it is present or the environment where it exists. It has been demanded.
　さらに、食品を取り扱う機器においては、殺菌処理直後だけでなく、機器の使用中にわたって減菌された状態を維持することが望まれる。したがって、素材についた微生物を殺菌又は静菌した後、そのまま継続的に該素材における微生物の増殖を抑えることを可能にする組成物の開発は、非常に有用であると考えられる。 Furthermore, it is desirable for devices that handle food to maintain a sterilized state not only immediately after sterilization but also during use of the device. Therefore, it is considered that the development of a composition capable of continuously suppressing the growth of microorganisms in the material after sterilizing or bacteriostatizing the microorganism attached to the material is very useful.
　本発明者らは、乳化剤とフィチン酸を含み、かつｐＨが３．５以下である液状組成物が、扱いやすく、また高い殺菌又は静菌作用を有することを見出した。さらに本発明者らは、当該液状組成物を素材に噴霧又は塗布することで、該素材における微生物の増殖を長時間にわたって抑制できることを見出した。 The present inventors have found that a liquid composition containing an emulsifier and phytic acid and having a pH of 3.5 or less is easy to handle and has a high bactericidal or bacteriostatic effect. Furthermore, the present inventors have found that the growth of microorganisms in the material can be suppressed for a long time by spraying or applying the liquid composition to the material.
　したがって、本発明は、乳化剤とフィチン酸とを含み、かつｐＨ３．５以下である、殺菌又は静菌用液状組成物を提供する。
　また本発明は、乳化剤とフィチン酸とを含み、かつｐＨ３．５以下である、対象への抗菌性付与用液状組成物を提供する。 Therefore, the present invention provides a bactericidal or bacteriostatic liquid composition comprising an emulsifier and phytic acid and having a pH of 3.5 or lower.
