Production of Biocomposite Packages from Natural SAPs and Investigation of Their Usability in Tomatoes

Abstract

In this study, composite packages that prevent plastic pollution and maintain food integrity for a prolonged period were produced. Natural superabsorbent polymers, which absorb water molecules that cause spoilage or are formed during spoilage in these packages, were produced from lemon, grapefruit, and pomegranate peels, which are domestic or factory waste. These characterized super-absorbents were mixed with bioplastic. The composite plates were then subjected to a series of analytical tests, including degradation, water absorption, and durability assessments. The experimental setup involved the packaging of cherry tomatoes in the plates under study, with 3 distinct groups of plates being tested under ambient conditions over a period of 10 days. It was observed that the tomatoes in the control group, which were packaged in polystyrene, deteriorated on the 6. day. However, it was determined that the tomatoes stored in the bio-composite plates, which had been treated with super-absorbent polymers derived from lemon peel and grapefruit peel, remained stable and were safely stored for a period of 10 days.

Doğal SAP’lardan Biyokompozit Paket Üretimi ve Domateste Kullanılabilirliğinin Araştırılması

Abstract

Bu çalışmada plastik kirliliğini önleyen, gıdaların daha uzun süre bozulmadan kalmasını sağlayan kompozit ambalajlar üretilmiştir. Bu ambalajlarda bozulmaya neden olan veya bozulma sırasında ortaya çıkan su moleküllerini absorplayacak doğal süper emici polimerler evsel veya fabrika atığı olan limon, greyfurt ve nar kabuklarından üretilmiştir. Karakterizasyonu yapılan bu süper emiciler biyoplastik ile karıştırılmıştır. Üretilen kompozit tabakların bozunma, su emme ve dayanım testleri gerçekleştirilmiştir. Değerlerin birbirine yakın olmasından dolayı 3 deney grubu ile çeri domatesler paketlenmiş ve oda koşullarında 10 gün süre boyunca test edilmiştir. Kontrol grubu polistiren tabaktaki domateslerin 6. günde bozulduğu görülürken, limon kabuğu ve greyfurt kabuğundan elde edilen süper emici polimer katkılı biyokompozit tabaklarda gıdalar sağlam bir şekilde 10 gün saklandığı tespit edilmiştir.
