Small mice (approximately 20 g) were anesthetized and placed in a loop-gap resonator of diameter 25 mm resonating at 1.1 GHz. An oxygen-permeable capsule containing 2.5 X 10(-2) M perdeutero 15N TEMPONE (1-oxyl-2,2,6,6-tetramethyl-4-piperidone) in light paraffin oil was implanted in the peritoneal c

โฆ Synopsis
Lipid oxidation attributed to the presence of oxygen has long been a focal area for food science research due in early years mainly to its broad impact on the quality and shelf stability. The need to effectively strategize interventions to detect and eventually eliminate lipid oxidation in food remains as evidence on nutritional and health implications continue to accumulate. Electron spin resonance (ESR) spin label oximetry has been shown capable of detecting dissolved oxygen concentration in both liquid and gaseous phases based on the collision between oxygen and stable free radicals. This review aimed to summarize not just the principles and rationale of ESR spin label oximetry but also the wide spectrum of ESR spin label oximetry applications to date. The feasibility to identify in very early stage oxygen generation and consumption offers a promising tool for controlling lipid oxidation in food and biological systems.
