PurposeThe purpose of this study was to prepare alginate and chitosan-based edible coatings incorporating Schinus terebinthifolia and Piper nigrum essential oils. The prepared films were applied on minimally processed pineapple to study the microbial inhibition of Gram + and Gram – bacteria and fungi and to evaluate the shelf life of the minimally processed fruit.Design/methodology/approachIn this study alginate and chitosan-based edible coating were prepared and applied on minimally processed pineapple. The edible coatings were evaluated microscopically, by the power of reducing microbial contamination, by the shelf-life improvement.FindingsThis study demonstrates that the incorporation of the essential oils P. nigrum and S. terebinthifolia contributed to the inhibition of all the microorganisms studied and improved the shelf life of minimally processed pineapple. This is especially true for P. nigrum in the chitosan-based edible coating, where the shelf life was improved by 45 days.Research limitations/implicationsBecause of the pandemic, it was not possible to perform the sensory analyses of the antimicrobial alginate and chitosan-based edible coatings prepared.Practical implicationsFrom the results obtained, it is possible to state that the antimicrobial alginate and chitosan-based edible coatings incorporating S. terebinthifolia and P. nigrum essential oils can be used on minimally processed fruits and prolong their shelf life.Social implicationsDue to the lifestyle of modern consumers, who demand speed and practicality and the need to consume fruits for health and quality of life, minimally processed fruits covered with edible coatings incorporating natural antimicrobial additives can provide a practical solution.Originality/valueTo the best of the authors’ knowledge, this is the first time that alginate and chitosan-based edible coatings that incorporate P. nigrum and S. terebinthifolia applied on minimally processed fruit, have been studied.

ABSTRACT: The effect of the incorporation of cinnamon (Cinnamomum cassia) and nut meg (Myristicafragrans) essential oils in alginate-based edible coatings that were applied on minimally processed apples, is reported. The minimum inhibitory concentrations were 1.25mg.mL-1 (cinnamon) and 2.50mg.mL-1 (nutmeg), against both Escherichia coli and Penicillium commune. Over storage periods there was a significant reduction in the E. coli and P. commune counts compared to the control. The extent of enzymatic browning was also significantly reduced in the coated samples. In the coated minimally processed apples sensory tests, the flavor had the lowest rating of the properties analyzed, for both treatments, followed by aroma and firmness.

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.
