Abstract

PURPOSE:To improve oxygen sensing performance and shelf stability by adding an opacifying agent to a compsn. consisting of methylene blue, a reducing saccharide, a basic material and aluminum hydroxide. CONSTITUTION:Aluminum hydroxide is added to a compsn. consisting of methylene blue, a reducing saccharide, a reducing agent and an additive such as an excipient to improve a shelf stability and further an opacifying agent is added thereto so that a bright color tone is obtd. in the stage of coloration. The aluminum hydroxide added and mixed therewith an opacifying agent, for example, a white pigment such as titanium oxide, zinc oxide, antimony oxide, or lithopon is used as a carrier in the above-mentioned way, whereby a dark color of an oxidation reduction dye, for example, dark blue is opacified and can be changed to a bright, distinct, and easily visible color. The opacifying agent is added according to the need for a desired color tone.

In recent years, due to restrictions on the use of food additives, etc., a method of enclosing an oxygen absorber inside a container has been proposed in order to prevent packed foods from oxidation and spoilage. There is a need for an oxygen sensing composition in tablet form. The oxygen-sensing composition uses a redox dye that reversibly changes color due to oxidation or reduction as a coloring component, and contains a reducing substance that maintains the dye in a reduced form, a reduction aid, and other excipients. It utilizes a reaction in which the dye changes from a reduced form to an oxidized form in the presence of oxygen, resulting in coloration. Conventionally, an aqueous oxygen-sensing composition using methylene blue as a dye, a sugar complex such as D-glucose as a storage substance, and hydroxylated as a reducing agent, or an aqueous oxygen sensing composition using the aqueous solution composition as Detection papers made by impregnating paper, etc. are known, but since the composition is in the form of an aqueous solution, the reaction speed of the coloring reaction is fast, but it is difficult to handle, and it particularly dislikes the presence of liquid substances. It has the disadvantage that it cannot coexist with things. In order to improve this drawback, a substantially solid oxygen sensing composition using an alkaline earth metal composition instead of sodium hydroxide used as a reducing aid has been proposed as a composition that can be in the form of a tablet. (Special Publication No. 56-24906)
However, the composition has the defect of extremely poor storage stability, as in the case of using hydroxylated IJium.
