Cinnamon Essential Oil

The effects of the sodium alginate (SA) coating incorporated with cinnamon essential oil nanocapsules (CEO-NPs) and Nisin, as a new edible coating, were investigated on the preservation of beef slices in the refrigerated storage for 15 days. All beef samples were analyzed for physicochemical properties (pH value, weight loss, the total volatile base nitrogen (TVB-N)) and antimicrobial activity against total bacterial count (TBC). Besides, the changes in color parameters and sensory attributes of all beef samples were evaluated. The results revealed that the incorporation of the complex of CEO-NPs and Nisin retarded the growth of the microorganism and reduced lipid oxidation, as determined by pH, TVB-N, and TBC. This can extend the shelf life of beef slices to 15 days. Moreover, the treatment with the SA coating, incorporating CEO-NPs and Nisin, significantly improved the weight loss, color, odor, textural, and broth attributes of the beef samples. The results suggest that the coating treatment enriched with CEO-NPs and Nisin could significantly inhibit quality deterioration of beef slices, and the complex of CEO-NPs and Nisin can improve antioxidant, antibacterial and sensory properties of the SA coating. Thus, the new edible coating could be regarded as a potential material to preserve beef slices.

Strawberry fruits have a short shelf life after harvesting due the physiological factors that enhances ripening such as respiration and transpiration. Sensory properties including color, texture, odor, and flavor are the main factors that makes fresh produce appealing to consumers, and they change very rapidly upon harvest. For this reason, quality preservation is essential during post-harvest handling and storage of strawberry fruits. Quality deterioration rates are higher in strawberry fruit cuts due to the mechanical damage and the loss of their natural protective barriers, resulting in an increase in moisture loss, respiration rates, and the deterioration of their sensory properties. The effect of a sodium alginate-calcium chloride edible coating on quality preservation and shelf life extension of strawberry cut fruits stored at 4 °C was studied. Control samples had mold growth initiated after one week of storage at 4 °C, while the coated fruit samples had a mold free shelf life extension for up to 15 days. The sodium alginate-calcium chloride edible coating was effective in reducing respiration and transpiration rates and delayed the increase of the pH and soluble solid content. Furthermore, the coating delayed surface mold growth for up to 15 days and preserved the sensory properties of the cut fruits such as color and texture.

Edible film and coatings are been looked upon for preservation of fruits, vegetables and bakery products. Extended shelf life with preservation of natural properties of food is always been a challenge; by incorporation of bio-actives in edible coatings, the shelf life can be increased as they are known for their antioxidant and antimicrobial properties. With this view, present study was undertaken, where edible coatings were prepared from starch, gelatin and glycerol and incorporated with Lemon peel extracts and coated on apples for increased shelf life. Antimicrobial activity of Lemon peel extracts was studied on eight organisms by broth dilution method and were found to be effective at concentration 3mg/mL-9mg/mL for bacteria and 50mg/mL- 90mg/mL for fungi. Fuji apples coated with starch-gelatin based edible formulation containing lemon peel extracts were studied for the effect of coating on fruit shelf life during storage for 28 days. Incorporation of lemon peel extract into edible coating improved shelf life with reducing rate of browning of apples.
