Notes:
—Reflectance spectrophotometry was used to study pigment changes in beef samples that (1) had been oxygenated and wrapped with an oxygen-impermeable film, (2) had been treated with ferricyanide and (3) had either treatment (1) or (2) plus malonic acid. Treatment (1) showed a metmyoglobin (MetMb) accumulation of 30% in 30 min, followed by reduction of MetMb. Malonic acid inhibited oxygen utilization and MetMb-reducing activity (MRA). Treatment (2) showed MRA that was inhibited by the presence of oxygen or malonic acid. Malonic acid inhibited oxygen utilization rather than directly inhibiting MRA.
