Abstract

In this study, it was aimed to produce chitosan (CH) biocomposite edible films by adding guar gum (GG) to chitosan at different ratios (5-20%). The physical, barrier, mechanical, optical, thermal, and microstructural properties of the composite films were investigated. The interaction between composite film components was investigated using FT-IR analysis, while thermal stability was investigated using DSC analysis. SEM analysis confirmed that the surface morphology of the composite films became smoother and more homogeneous with increasing GG content. The lowest moisture content (21.27%) and water vapour permeability were found in the CH film with 15% GG addition, and the lowest water solubility (16.21%) was found in the chitosan film with 20% GG addition. The highest tensile strength (19.64 MPa) was determined in the chitosan film with 10% GG addition, and the highest elongation at break (15.68%) and opacity value were determined in the chitosan film with 5% GG addition. Compared to the CH control film, it was observed that the addition of GG decreased the moisture content, water solubility, water vapour permeability, and flexibility of the chitosan composite films, while opacity and tensile strength increased. Our findings showed that CH composite films with GG addition could be a promising alternative to traditional packaging with their biodegradable, environmentally friendly, and edible properties.

Özet

Bu çalışmada kitosana (CH) farklı oranlarda (%5-20) guar gam (GG) ilave edilerek kitosan biyokomkozit yenilebilir film üretilmesi amaçlanmıştır. Kompozit filmlerin fiziksel, bariyer, mekanik, optik, termal ve mikroyapısal özellikleri incelenmiştir. Kompozit film bileşenleri arasındaki etkileşim FT-IR analizi ile termal kararlılığı ise DSC analizi ile araştırılmıştır. Kompozit filmlerin artan GG oranıyla daha pürüzsüz ve homojen yüzey morfolojisi sergilediği SEM analizi ile teyit edilmiştir. En düşük, nem içeriği (%21.27) ve su buharı geçirgenliği %15 GG ilaveli CH filmde, en düşük suda çözünürlük (%16.21) ise %20 GG ilaveli kitosan filmde tespit edilmiştir. En yüksek gerilme direnci (19.64 MPa) %10 GG ilaveli kitosan filmde, en yüksek kopma uzaması (%15.68) ve opaklık değeri %5 GG ilaveli kitosan filmde belirlenmiştir. Kitosan kontrol filmine kıyasla, GG ilavesi ile CH kompozit filmlerin suda çözünürlüğü, su buharı geçirgenliği ve esnekliği azalırken, opaklığın ve gerilme direncinin arttığı gözlenmiştir. Bulgularımız, GG ilaveli CH kompozit filmlerin biyobozunur, çevre dostu ve yenilebilir özellikleriyle geleneksel ambalajlara umut verici bir alternatif olabileceğini göstermiştir.
