| heal.abstract | The ability of N-acetyl-cysteine and glutathione to inhibit the oxidation of butter was evaluated. Peroxide value and thiobarbituric acid reactive substances were monitored during storage of butter at 50 degrees C for up to 84 days and at 110 degrees C for up to 12 h. N-Acetyl-cysteine and glutathione inhibited butter oxidation at 50 degrees C and at 110 degrees C. They were active at 10 mg/L and in a higher degree at 20 mg/L. N-Acetyl-cysteine appeared to be more active than glutathione. At 50 degrees C, N-acetyl-cysteine at 20 mg/L exhibited antioxidant activity comparable to that of butylated hydroxyanisole (BHA) at 200 mg/L. Volatile aldehydes were also determined during storage of butter at 50 degrees C for 10 days. N-Acetyl-cysteine and glutathione, each at 20 mg/L, inhibited the formation of several volatile aldehydes such as hexanal to an extent equal to BHA at 200 mg/L. Present results indicate that N-acetyl-cysteine and glutathione, especially the former, may be taken into account as antioxidants in butter during storage and cooking. | en |
