Effect of sodium alginate coating containing clove ( Syzygium Aromaticum ) and lemon verbena ( Aloysia Citriodora ) essential oils and different packaging treatments on shelf life extension of refrigerated chicken breast

Abstract

The present study was conducted to preserve the microbial quality of chicken breast during storage time by using sodium alginate active coating solutions incorporated with different natural antimicrobials including Lemon Verbena (Le) and clove essential oils (Cl) which were added individually and in combination as well as packaging in Modified Atmosphere (M) (65% CO 2 , 30% N 2 , and 5% O 2) and in ambient atmosphere (A). The samples were stored in refrigeration condition for 15 days and were analyzed for total viable count, Enterobacteriaceae count, lactic acid bacteria count, Pseudomonas spp. count, psychrotrophic count, and yeast and mold count, as well as pH, TBA, TVN, and sensory analyses at 5-day intervals. After 15 days of storage it was found that coating with sodium alginate containing 0.5% of Cl and 0.5% Le in modified atmosphere packaging is the most effective combination in lowering aerobic mesophilic bacteria, Pseudomonas, Psychrotrophic bacteria, Enterobacteriaceae, mold, and yeast. Results indicated that Le 0.5 C 0.5 M had the lowest pH (5.76) after 15 days. Lipid oxidation increased rapidly after 5 days of storage all treatments while 2 | MATERIAL S AND ME THODS 2.1 | Materials Dried leaves of A. citriodora and dried flowers of buds of S. aromaticum were purchased from, local markets in Gorgan, Iran and the species were identified in Golestan Agricultural and Natural Resources Research and Educational Center. Sodium alginate was purchased from Sigma-Aldrich (Sigma-Aldrich Chemical Co. St. Louis, USA). All culture media were purchased from Merck (Merck, Darmstadt, Germany). All other chemicals used were of analytical grade and were provided by Merck Chemical Co.

Algae: Study of Edible and Biologically Active Fractions, Their Properties and Applications

“…The results indicate the possibility of substituting conventional materials with sodium alginate/agar biopolymer. The same beneficial effect of natural extracts was shown by [ 177 ] when they packed chicken breast in polymer foils with the addition of essential oils of lemon and verbena or by Kang et al [ 178 ] when they packed low-fat frankfurters in sodium alginate film. Takma and Korel [ 179 ] produced active ethylene terephthalate (PET) films composed of chitosan and alginate as coatings incorporated with black cumin oil.…”

“…The authors acknowledge the beneficial effects of adding basil to the film matrix. The same beneficial effect of natural extracts was shown by Hosseini et al [ 52 ] when they packed chicken breast in polymer foils with the addition of essential oils of lemon and verbena or by Kang et al [ 53 ], when they packed low-fat frankfurters in sodium alginate film.…”

Antibacterial activity of clove (Syzygium aromaticum) and cinnamon (Cinnamomum burmannii) essential oil against extended-spectrum β-lactamase-producing bacteria

“…Eugenol in clove and cinnamaldehyde in cinnamon can cause lysis to bacterial membranes and inhibit β-lactamase production in E. coli, as previously reported [11]. Previous studies also reported that clove and cinnamon essential oils can enhance the shelf life of chicken meat [12,13]. In this research, we test the antibacterial activity of clove and cinnamon essential oils against ESBLproducing bacteria.…”
