| Chicken meat is a popular food around the world due to its high nutrient
content, low fat content and relatively low cost. Perishable and enrich
chicken meat caused it sensitive spoilage and fat oxidation, so reduce the
shelf-life of the product. The aim of this study was to investigate the effect
of chitosan (Ch) and cumin essential oil (CEO) on the quality and shelf life
chicken meat. Ch-CEO coatings were prepared in three treats covered
chitosan, cumin essential oil / chitosan and essential oil of cumin 0.2, 0.4
and 0.6%. The microbial tests (Total count, Enterobacteriaceae,
Staphylococcus aureus (S. aureus), Escherichia coli (E. coli), mold and
yeast), the chemical tests (pH, Total volatile nitrogen (TVN), Thiobarbituric
acid (TBA), Peroxide value (PV) and 2,2-diphenyl-1-picrylhydrazyl
(DPPH) and sensory properties were assessed in 2, 5, 9 days. There was a
significant difference in microbial load between control and treated samples
with Ch-CEO (0.6%). The most antioxidant activity, TBA and PV have been
shown to be CEO (0.6%). In all of concentration of CEO, pH and TVN
decreased. Sensory properties in treating samples with Ch-CEO were
acceptable in the second day, but in final storage period showed significant
differences with the control sample. The results show that due to the
antioxidant activity of CEO and the high antimicrobial activity of chitosan
coating and the synergistic effect of both of them improved of sensory
properties and increase shelf life chicken meat at the refrigerator
temperature. |
