Abstract

Son yıllarda, malzeme bilimindeki ilerlemelerle birlikte çevre, sağlık ve gıda sektörlerinde karşılaşılan sorunlara doğal çözümler arayışı artmıştır. Atık plastiklerin çevresel kirlilik yaratması ve toksik olmaları büyük endişe kaynağıdır. Bu nedenle, doğal polimer filmlerin geliştirilmesi, özellikle gıda endüstrisinde plastiklerin yerini alabilecek bir alternatif sunar. Bu çalışmada, omega-3, protein, yağ ve lif açısından zengin chia tohumundan elde edilen müsilaj ve polidimetilsiloksan (PDMS) filmlerinin kombinasyonuyla çift katmanlı filmler üretilmiştir. Filmlerin fizikokimyasal özellikleri Fourier dönüşümü kızılötesi spektroskopisi, termogravimetrik analiz, taramalı elektron mikroskobu ve enerji dağılımlı X-ışınları spektroskopisi gibi yöntemlerle karakterize edilmiştir. Son olarak, filmlerin su temas açısı ölçülmüş olup, çift katmanlı filmlerin iç tarafının hidrofilik dış tarafının ise hidrofobik özelliklere sahip olduğu gösterilmiştir. Bu çalışma, çift katmanlı müsilaj-PDMS filmlerinin potansiyel olarak gıda paketleme uygulamalarında kullanılabilir bir alternatif ürün olabileceğini ortaya koymaktadır.

Double-Layered Alternative Food Coatings Developed with Mucilage and PDMS

Abstract

In recent years, in parallel with advancements in materials science, there has been a growing pursuit of natural solutions to address environmental, health, and food industry challenges. The environmental pollution and toxicity associated with waste plastics have raised significant concerns. Therefore, the development of natural polymer films, particularly those derived from chia seeds rich in omega-3, protein, oil, and fiber, presents an alternative that could replace plastics in the food industry. In this study, double-layer films were produced by combining mucilage extracted from chia seeds and polydimethylsiloxane (PDMS). The physicochemical properties of the films were characterized using methods such as Fourier-transform infrared spectroscopy, thermogravimetric analysis, scanning electron microscopy, and energy-dispersive X-ray spectroscopy. Finally, the water contact angle of the films was measured, demonstrating that the inner side of the double-layer films is hydrophilic, while the outer side exhibits hydrophobic properties. This study suggests that dual-layer mucilage-PDMS films could be a potentially viable alternative in food packaging applications.
