Polyvinyl Alcohol / Starch Active Composite Films Containing Rosemary Extract and Kaolin : Structural, Mechanical and Antioxidant Activity Properties

Abstract

The biodegradable packaging industry is constantly growing due to the need to prevent waste disposal problems caused by petroleum-based plastics. In recent years, efforts to improve biodegradable and active packaging have been increasing. In this study, the effects of polyphenols rich rosemary (Rosmarinus officinalis L.) extract and kaolin on the properties of polyvinyl alcohol / corn starch based films were investigated. Structural properties of films were determined by FT-IR analysis, mechanical properties tensile test, morphological properties by optical microscope. Swelling behavior of films was examined. In addition, antioxidant activity was determined with ABTS and DPPH radical removal activity. The addition of extract and clay improved the mechanical properties of the film while increasing the water absorption. The films exhibited antioxidant activity with the addition of extract. The results showed that these films could be considered as potential candidates in active packaging applications.

Biberiye Ekstresi ve Kaolin İçeren Polivinil Alkol/Nişasta Aktif Kompozit Filmler: Yapısal, Mekanik ve Antioksidan Aktivite Özellikleri

Abstract

Biyobozunur ambalaj endüstrisi, petrol esaslı plastiklerin yol açtığı atık bertaraf sorunlarının önlenmesi ihtiyacı nedeniyle sürekli büyümektedir. Son yıllarda, biyobozunur ve aktif ambalajların geliştirilmesine yönelik çalışmalar artmaktadır. Bu çalışmada, polifenollerce zengin biberiye (Rosmarinus officinalis L.) ekstresi ve kaolinin polivinil alkol/mısır nişastası esaslı filmlerin özelliklerine olan etkisi incelendi. Filmlerin yapısal özellikleri FT-IR analizi, mekanik özellikleri çekme testi, morfolojik özellikleri optik mikroskop ile belirlendi. Filmlerin şişme davranışları incelendi. Ayrıca, ABTS ve DPPH radikali giderme aktivitesi ile antioksidan aktivitesi belirlendi. Ekstre ve kilin birlikte ilavesi filmin mekanik özelliklerini iyileştirirken su absorpsiyonunu da arttırdı. Ekstre ilavesi ile filmler antioksidan aktivite sergiledi. Sonuçlar bu filmlerin aktif ambalajlama uygulamalarında potansiyel adaylar olarak değerlendirilebileceğini gösterdi.
