An improved automated analysis of hypoxanthine

Abstract

Summary. The level of hypoxanthine in fish muscle is a good indicator of fish quality. Its routine determination can be carried out reliably and quickly with the AutoAnalyzer using a redox indicator dye. Interference from formaldehyde and acetaldehyde in extracts of fish muscle, at concentrations greater than would be expected there, is not significant. Results obtained using this method correlate very well with those from the standard manual enzymatic assay procedure.
