| Firstly, postbiotics of Lactobacillus paracasei ATCC 55544 (PLP) were isolated and characterized. Secondly, PLP has been utilized in Malva sylvestris mucilage (MSM) coating, and its antioxidant and antimicrobial properties on lamb meat slices were assessed in 10 days at 4 °C. The main chemical compounds of the PLP were identified and quantified by a gas chromatograph coupled to a mass spectrometer. Various microbiological and sensory assessments were also applied regarding the coated lamb meat slices. PLP contains pyrrolo [1,2-a] pyrazine-1,4-dione, and 5,10-Diethoxy-2,3,7,8-tetrahydro-1H,6H-dipyrrolo[1,2-a:1',2'-d]pyrazine as well as various organic acids with strong radical scavenging activity and antibacterial effect against investigated pathogenic microorganisms. The PLPloaded MSM edible coating greatly postponed the growth of microorganisms and extended the product life (>10 days). Moreover, sensory parameters of the samples were preserved more efficiently during cold storage when the PLP-enriched edible coating, particularly MSM+8% PLP, was used. Using edible coating based on MSM and PLP effectively reduces microbial growth in lamb meat during storage. |
