چکیده مقاله:
Background: Lemongrass (Cymbopogon citratus) is an aromatic herb; rich source of citric, vitamin C, and phenolic compounds used as natural antioxidant and antibacterial agents in food processing. This study aimed to evaluate the effect of lemongrass extract on the quality properties of chicken burger during frozen storage.
Methods: Lemongrass extract was prepared with three levels (۰.۵, ۱.۰, and ۱.۵%) in the formulation of chicken burger and its effect was studied on some chemical, physical, and microbiological quality characteristics during frozen storage at -۲۰ °C for ۹۰ days. Data were analyzed using statistical analysis system (SAS, ۲۰۰۰).
Results: Chicken burger treated with different levels of lemongrass extract exhibited the lowest pH values than control one. L* values (the lightness) of treated chicken burger showed a gradually decrease as the level of lemongrass increased. Significant increase (p<۰.۰۵) was found in a* value (the redness) of chicken burger formulated with ۱.۵% lemongrass after ۳۰ days of storage and remained constant during frozen storage period ۹۰ days. Significant differences (p<۰.۰۵) were found in b* value (the yellowness) during frozen storage of chicken burger treated with different levels of lemongrass extract. Chicken burger formulated with ۱.۵% lemongrass extract exhibited a significant decreased (p<۰.۰۵) in Thiobarbituric Acid (TBA) value at the end of frozen storage period ۹۰ days.
Conclusion: Using different levels of lemongrass extract in the formulation of chicken burger resulted in delaying the lipid oxidation, improved the color stability, and reduced the bacterial count during frozen storage.
