Antimicrobial and antioxidant effects of an edible coating of Lepidium sativum seed mucilage and Satureja hortensis L. essential oil in Uncooked lamb meat

The current research aimed to fabricate an active edible coating, Lepidium sativum seeds mucilage (LSSM) loaded with Satureja hortensis essential oil (SHEO) (0, 0.5, 1, and 1.5 % (w/w)) for further extension of the shelf life of refrigerated lamb meat during storage for 18 days at (4 degrees C). The control and the coated lamb meat samples were continually analyzed for microbiological (total count, psychrotrophic count, yeast and mold), chemical (pH, moisture content, PV, and TBA), and sensory characteristics. Consistent with the microbiological analysis, the LSSM incorporated with 1, and 1.5% SHEO caused a significant shelf-life extension of the lamb meat by 15 and 18 days, respectively. These results suggested that (LSSM+1.5%S) sufficiently hindered the overall bacterial growth in the lamb meat sample since the shelf life in this treatment was 12 days more in comparison to the control. Hence, LSSM containing SHEO is very useful as an active packaging in order to preserve the quality and to prolong the lamb meat shelf life at 4 degrees C.
