Citrus Limon L. Peel Powder Incorporated Polyvinyl Alcohol/Corn Starch Antioxidant Active Films

Abstract

Active food packaging films has gain more significance over conventional packaging. In this study, novel active composite films were prepared by incorporating lemon peel to a polyvinyl alcohol-starch matrix. The morphological, thermal and antioxidant activity evaluation of polyvinyl alcohol-starch-lemon peel composite films were discussed to determine whether the presence and content of lemon peel influenced the film's characteristics. The results indicated that tested properties of composite films depended on the content of lemon peel. It was found that the thermal stability and antioxidant activity of films considerably improved upon the incorporation of peel. The prepared films with enhanced antioxidant activity may be used for preservation of oxidation-sensitive food products. The results showed that lemon by-product has great potential to be evaluated into added-value products for functional packaging applications. The developed packaging films will be new alternatives for food preservation materials.

Fabrication and characterization of a smart film based on cassava starch and pomegranate peel powder for monitoring lamb meat freshness

“…(2021) achieved similar results in investigating pomegranate peel's effect on pectin‐based edible films’ antioxidant activity of chitosan‐modified dialdehyde guar gum films, respectively. The addition of lemon peel powder to polyvinyl alcohol–starch films also significantly increased the antioxidant activity of the film samples (Terzioglu & Sicak, 2021).…”

Investigation of Properties of Microcrystalline Cellulose and Apple Peel Incorporated Polylactic Acid Based Films

“…Filmlerin termal bozunması termogravimetrik diferansiyel termal analiz (TG/DTA) tekniği ile TA/SDT650 (TA Instruments, Inc., New Castle, ABD) cihazı kullanılarak belirlendi. Analizler filmlerin sırasıyla nitrojen atmosferi ve oksijen atmosferi altında 25 °C'den 600 °C'ye ve 600 °C'den 900 °C'ye çıkılması ile gerçekleştirilmiştir [20]. Isıtma hızı 20 °C/dk olarak çalışılmıştır.…”
