Elektroeğirme, yüksek yüzey alanı/hacim oranına sahip
farklı boyutlarda liflerin üretimi için yenilikçi bir yöntemdir. Bu çalışmanın
amacı, nane uçucu yağı yüklü ve kitin lifleri/kitin mikro kristalleri ile
güçlendirilmiş zein bazlı nanobiyokompozit malzemelerin elektroeğirme yöntemi
ile üretilmesidir. Üretilen nanobiyokompozitlerin yüzey morfolojisi, mekanik
özellikleri ve antimikrobiyal aktiviteleri belirlenmiştir. Polimer çözeltisine
kitin liflerinin eklenmesi ile ortalama lif çapı artmıştır. Kitin mikro
kristalleri içeren malzemelerin mekanik özelliklerinin, kitin lifi içeren
malzemelere göre daha zayıf mekanik özelliklere sahip olduğu bulunmuştur. Kitin
lifleri ve nane uçucu yağı içeren malzemeler test mikroorganizmaları üzerinde
berrak zon oluşturmamıştır. Fakat kitin mikro kristalleri ile birlikte nane
uçucu yağı içeren malzemeler, Staphylococcus aureus üzerinde Escherichia
coli’den daha etkili olmuştur. Üretilen nanobiyokompozit malzemelerin
potansiyel aktif ambalajlama sistemlerinin geliştirilmesinde kullanılabileceği
düşünülmektedir.

INVESTIGATION OF ELECTROSPUN NANOFIBERS STRENGTHENED WITH CHITIN AS ACTIVE PACKAGING MATERIAL

Öz

Electrospinning is an innovative method for the
production of fibers with different sizes having a high surface area/volume
ratio. The aim of this study was to produce zein based nanobiocomposite active
packaging materials loaded with mint essential oil and strengthened by chitin
fibers/chitin microcrystals using electrospinning. Surface morphologies,
mechanical properties and antimicrobial activities of the produced
nanobiocomposites were determined. The average fiber diameter increased with
the addition of chitin fibers into polymer solution. It was found that the
mechanical properties of materials containing chitin microcrystals were weaker
than the materials containing chitin fibers. The composite materials containing
chitin fibers and mint essential oil did not form a clear zone on the test
microorganisms. However, materials containing chitin microcrystals with mint
essential oil were more effective on Staphylococcus aureus than Escherichia
coli. It is considered that nanobiocomposites produced can be used in the
development of potential active packaging systems.
