Abstract:In order to study the oxidative stability of mutton oxymyoglobin (OxyMb), OxyMb was prepared from mutton myoglobin (Mb). The effects of NaCl, pH value, temperature and plant extracts on the stability of OxyMb were investigated under conditions simulating auto-oxidation of OxyMb. Results showed that the relative content of OxyMb increased at first and then decreased with increasing NaCl concentration, reaching the highest value of 67.07% at 1.5 g/100 mL. The stability of OxyMb in alkaline environment was higher than that in acidic environment. OxyMb could remain relatively stable in the temperature range of 4–30 ℃. The relative content of OxyMb decreased significantly when the temperature were higher than 35 ℃, while the relative content of metmyoglobin increased. Magnolia extract and bamboo leaf extract could improve the stability of mutton OxyMb.
