Abstract
The present study aimed to evaluate the effect of free and microencapsulated Ziziphora clinopodioides Essential Oil (ZEO) and Nisin individually and in combinationon sensory characteristic and shelf life of fish burger during 20 days of storage at 4±1˚C. Fish burgers were prepared and treated with free and microencapsulated form of ZEO and Nisin in 15 treatments and evaluated by 20 stable semi-trained people using a 9-point hedonic screen method on days 0, 5, 10, 15, 20. The chemical composition of fish burgers was also analyzed at the first day of storage. Results indicated that both microencapsulation and combinational use of ZEO and Nisin improved sensorial scores of treated samples during 20-day storage at 4±1˚C (P< 0.05), and samples containing microencapsulated ZEO and Nisin showed the strongest effect on preserving the sensorial quality of fish burgers.
