Effects of ethanolic extract from onion skin on the quality characteristics of beef patties during refrigerated storage
Abstract In this study, the effects of ethanolic extract from onion skin (EEOS) on the storage quality of refrigerated beef patties were studied. EEOS concentrations of 0.00%, 0.01%, 0.05%, and 0.10% were added to beef patties. These beef patties were stored at 4 °C for 12 days and compared with 0.05 VC treatment group. At the end of storage, compared to control, 0.1% EEOS effectively reduced the contents of metmyoglobin (MetMb) (P < 0.05) and thiobarbituric acid reactants (TBARS) (P < 0.05) in beef patties by 30.89% and 44.72%, respectively. On day 12, the carbonyl contents in 0.1% EEOS treatment increased only 3.3 times, lower than control and VC treatment (4.5 and 4.1 times). Microbial contamination was significantly inhibited (P < 0.05). The antioxidant and antibacterial effects of EEOS were the main reasons for the improvement of pH and a* stability of beef patties. However, the addition of EEOS had no significant effect on cooking loss and texture properties except hardness and springiness. Overall, 0.1% EEOS had a positive effect on the sensory characteristics and storage quality of beef patties and could prolong the storage life of beef patties to 9 days. This showed that EEOS as a natural additive has great potential for beef storage and preservation.
