Description

食品添加物として使用される過酢酸組成物の製造方法Process for producing peracetic acid composition used as food additive
 本発明は、食品添加物として使用される過酢酸組成物の製造方法に関し、更には、食品添加物として使用される過酢酸組成物を製造する製造装置、及び食品添加物として使用される過酢酸組成物に関する。 The present invention relates to a method for producing a peracetic acid composition used as a food additive, and further to a production apparatus for producing a peracetic acid composition used as a food additive, and peracetic acid used as a food additive It relates to a composition.
 酢酸と過酸化水素とを原料として、過酢酸水溶液が合成できることは古くから知られている。例えば、特公昭61-10465号(特許文献1)、特公昭37-7459号公報、或いはFRANK P. GREENSPANの報告(J. Amer. Chem. Soc., 68, 907(1946))には、反応条件や原料仕込比の選択により、過酢酸濃度が1~50重量%の過酢酸水溶液が合成できることが記載されている。 It has long been known that an aqueous peracetic acid solution can be synthesized from acetic acid and hydrogen peroxide as raw materials. For example, reaction to JP-B-61-10465 (Patent Document 1), JP-B-37-7459, or the report of FRANK P. GREEN SPAN (J. Amer. Chem. Soc., 68, 907 (1946)). It is described that an aqueous peracetic acid solution having a peracetic acid concentration of 1 to 50% by weight can be synthesized depending on the conditions and selection of the raw material feed ratio.
 また、そのようにして得られた過酢酸水溶液は、例えば、特公昭61-10465号、特公昭61-14122号公報に記載されているように、その酸化力のために優れた殺菌、消毒、漂白等の能力を有することも古くから知られている。一方、過酢酸水溶液は、他の有機過酸と同様、元来不安定な物質であり、加熱したり、不純物による汚染などにより、激しく分解するため、使用に際して、貯蔵安定性が劣ることが大きな欠点となっていた。過酢酸水溶液の貯蔵安定性を直接向上させる安定剤は、これまでに知られていないが、微量存在する金属イオンを封止することにより、間接的に貯蔵安定性を向上させることが知られていた。 Moreover, the peracetic acid aqueous solution thus obtained is excellent in sterilization and disinfection due to its oxidizing power, as described in, for example, JP-B-61-10465 and JP-B-61-14122. It has also long been known to have the ability to bleach and the like. On the other hand, peracetic acid aqueous solution, like other organic peracids, is an inherently unstable substance and is strongly degraded due to heating, contamination with impurities, etc., and therefore storage stability is largely inferior upon use It was a drawback. Stabilizers that directly improve the storage stability of aqueous peracetic acid solutions are known to indirectly improve the storage stability by sealing metal ions present in small amounts, although these have not been known so far. The
 上記のように、過酢酸水溶液は優れた殺菌、消毒、漂白等の能力を有しているが、使用に際して、貯蔵安定性が劣ることが大きな欠点となっていた。この問題の解決のため、これまでに、種々の過酢酸水溶液の貯蔵安定性を向上する方法が提案されているが、さらなる貯蔵安定性を向上する方法が望まれていた。 As described above, the aqueous peracetic acid solution has excellent ability to disinfect, disinfect, bleach, etc., but its storage stability has been a major drawback in use. In order to solve this problem, methods for improving the storage stability of various peracetic acid aqueous solutions have been proposed so far, but methods for further improving the storage stability have been desired.

(Comparative example 1)
35% by mass aqueous hydrogen peroxide solution (manufactured by Mitsubishi Gas Chemical Co., Ltd., product name: UELM 35) instead of 35% by mass aqueous hydrogen peroxide solution (manufactured by Mitsubishi Gas Chemical Co., Ltd., product name: Diapower HP, containing a small amount of aluminum) The same procedure as in Example 1 was repeated except that 5.5% by mass of hydrogen peroxide, 48.7% by mass of acetic acid, 13.5% by mass of peracetic acid, and 1-hydroxyethylidene-1,1- were obtained. A peracetic acid composition used as a food additive containing 0.8% by mass of diphosphonic acid was obtained. About the obtained peracetic acid composition, the total peroxide concentration was measured 21 days after preparation, and stability was computed.
