Abstract

PURPOSE: To provide an oxygen indicator of improved light resistance by comprising essentially a vat dyeing dye, a sulfur dye and a reducing agent and contg. water therein.
CONSTITUTION: 0.1W1,000pts. reducing agent such as glucose and a proper amount of water are added to 1pt either of a vat dyeing dye of indigo base etc. and a sulfur dye of blue-base water soluble type etc. or both. Further, preferably, ≤10,000pts. alkaline material such as sodium hydroxide, and ≤50,000pts. extender such as magnesium oxide are added. This is molded to tablet type or is made into the state of powder, which is then sealed into transparent and air permeable bags. Since this oxygen indicator has superior light resistance, it is suited for deoxidizing preservation packaging of food, etc.
