Abstract
Oxidation is one of the major causes of hamburger deterioration. Antioxidants are used to minimize oxidation process.
There is a growing interest in the substitution of synthetic food antioxidants by natural ones from vegetable sources. In meat industry,
sodium erythorbate is antioxidant that is usually used and is an example of chemical antioxidant. Effect of olive leaf extract rich in
oleuropein on the quality of frozen hamburger was investigated. The objective of this study was to evaluate the usage of oleuropein
from olive leaf extract as natural antioxidant in frozen hamburger stored at -12 °C compared with sodium erythorbate. Results
suggested that olive leaf extracts might be useful to the meat industry as an efficient alternative to synthetic antioxidants by retarding
oxidation of hamburger compared with sodium erythorbate 0.5% of oleuropein and 0.5% of sodium erythorbate are the best
concentrations to be used in frozen hamburger.
