    摘要: The invention relates to a method of monitoring a sterilization process having an oxidation-type sterilant, said process comprising the steps of: providing an indicator compound capable of exhibiting a color change upon exposure to the sterilant, the indicator compound being free of heterocyclic nitrogen, diazo nitrogen and amino nitrogen, and selected from the group consisting of anthraquinone dyes, triarylmethane dyes and xanthene dyes; exposing the indicator compound to the sterilization process; and observing the compound for a change of colour. The invention also relates to an indicator for an ozone sterilization process. A preferred indicator compound is rosolic acid.
