| This study was designed and performed to evaluate the effect of using the active edible coating of sodium alginate containing different levels of rosemary extract on physicochemical and microbial properties of silver carp-chicken fillet mixed burger during storage. 5 treatments including uncoated burgers (control) with sodium alginate coating enriched with levels of 0, 0.5, 1 and 1.5% of rosemary extract were considered. Burgers were stored at -18 ° C for 3 months. Results showed that the use of sodium alginate coating significantly decreased the percentage of burger cooking drop. Enrichment of sodium alginate coating with different levels of rosemary extract improved its performance (P<0.05). The lowest total microbial count, psychrophilic bacteria count, TVN, PV and TBA were observed in coated burgers containing 1.5% of rosemary extract (P<0.05). There was no statistically significant difference in the performance of coatings containing levels of 1 and 1.5% of rosemary extract in decreasing TBA. Thus it is possible to use the active edible coating of sodium alginate containing 1.5% of rosemary extract to delay bacterial and oxidative spoilage of silver carp-chicken fillet burgers during a 3-month storage period at -18 ° C used. |
