    A Novel Synbiotic Edible Film Based on Aquafaba, Psyllium Husk Powder, Peg 400, and Lactiplantibacillus Plantarum 299v and Applicability on Kashar Cheese
    (Springer, 2024) Ilikkan, Ozge Kahraman; Bagdat, Elif Seyma; Yilmaz, Ilkay; Beyter, Nurten; Yuzay, Isinay Ebru
    In this study, it was aimed to compare a novel synbiotic edible film based on aquafaba, psyllium husk powder, and PEG 400 with or without Lactiplantibacillus plantarum 299v. Therefore, primarily, optimization of the edible film was carried out by Box-Behnken design in response surface methodology (rsm). The characterization of edible films with or without probiotic bacteria was performed by FTIR, viscosity, pH, total solid content, water and oxygen solubility, film thickness, color L*, a*, b*, transparency, and film tensile strength. It was determined that there was no statistically significant difference in viscosity, pH, lightness L*, water vapor, and oxygen permeability values with the addition of probiotic lactic acid bacteria to the optimized coating film samples. In addition, it was observed that the probiotic bacteria count did not decrease below 108 cfu/g for 60 days of storage. The resulting edible film formulation with (PL) and without (PS) probiotics was used to coat Kashar cheese, while control cheeses (C) were not coated. As a result, it was observed that the microbiological quality of the coated cheeses was as good as control or better than control especially at the end of storage in terms of mold/ yeast and coliforms. Sensory evolution revealed coating films with or without probiotics did not change the texture, flavor, odor, or appearance of cheeses. Physicochemical properties such as pH, % titratable acidity, % dry matter, % fat, and % salt were detected.

    Development and Characterization of Nitrocellulose/Acrylic-based Coatings With Precipitated Silica and Kaolin for Packaging Applications
    (Emerald Group Publishing Ltd, 2022) Akarca, Tuba Kavas; Karayol, Merve; Yuzay, Isinay E.
    Purpose The purpose of this study is to develop a multifunctional coating layer based on nitrocellulose (NC)/acrylic resins containing precipitated silica and kaolin and investigate its suitability for use in packaging applications. Design/methodology/approach Different loading levels (1 and 5 Wt.%) of precipitated silica or kaolin particles were incorporated into NC/acrylic-based coating formulations and applied on low-density polyethylene (LDPE) films. The coatings and coated LDPE films were characterized in terms of structural, physical, mechanical, thermal, optical, surface, morphological and water vapor barrier properties. Findings The glossiness of the coating formulations decreased by increasing the precipitated silica and kaolin content. The incorporation of kaolin (1 and 5 Wt.%) and precipitated silica (1 Wt.%) had no significant effect on the melting temperature of LDPE film; however, with the addition of 5 Wt.% precipitated silica, the melting and crystallization temperatures were significantly changed. The incorporation of 5 Wt.% precipitated silica and kaolin also enhanced the water vapor barrier properties of LDPE films. The light transmittance declined with the precipitated silica and kaolin addition, especially in the ultraviolet (UV)-A/UV-B spectrum regions indicating an excellent UV light protection. Originality/value It was concluded that NC/acrylic resins coatings containing precipitated silica and kaolin exhibit improved thermal stability, UV and water vapor barrier properties and have the potential for use in packaging applications.

    Master Thesis
    Development of Poly(lactic Acid) Films Incorporated With Almond Skin Extract
    (İzmir Ekonomi Üniversitesi, 2021) Tabakoğlu, Sahranur; Yüzay, Işınay Ebru
    Bu tezde, doğal kaynaklı bir ekstrakt kullanılarak fonksiyonel bir kompozit polimer film geliştirilmesi amaçlanmıştır. Bu amaçla doğal bir antioksidan kaynağı olarak badem zarı kullanılmıştır. Badem zarından antioksidan özellik gösteren polifenolik bileşiklerin ekstraksiyonu yapılmıştır. Polimer matrisi için ise doğal hammaddeden üretilen ve biyolojik olarak parçalanabilen poli(laktik asit) kullanılmıştır. Hazırlanan badem zarı ekstraktı (BZE) PLA çözeltisine eklendi ve PLA-BZE film örnekleri hazırlamak için ağırlıkça %1.8, 3.2, ve 4.6 olmak üzere üç farklı ekstrakt konsantrasyonu kullanıldı. Filmleri oluşturmak için solvent döküm yöntemi kullanıldı.PLA-BZE film örneklerinin oluşturulmasından sonra yapısal, gaz bariyeri, termal, mekanik, optik, yüzey morfolojisi özellikleri ve antioksidan aktiviteleri analiz edildi. BZE ilavesi, ekstrakt miktarından bağımsız olarak filmlerin oksijen geçirgenliğini düşürürken, su buharı geçirgenliği özelliğinde ekstrakt miktarıyla ilişkili olarak bir artışa neden olmuştur. Ek olarak, saf PLA (BZE ilavesiz) filminin ultraviyole-görünür ışık bariyeri, badem zarı ekstresinin eklenmesiyle önemli ölçüde iyileştirildi. Diferansiyel taramalı kalorimetri (DSC) sonuçları, badem zarı ekstresinin kompozit filmlerin termal geçiş noktalarını etkilemediğini gösterdi. Mekanik özelliklerde ise badem zarı ekstresi miktarına bağlı olarak bir azalma gözlenmiştir. Filmlerin antioksidan aktivitesini araştırmak için DPPH radikal yakalayıcı aktivite (RSA) analizi yapıldı ve anlamlı ölçüde RSA gözlemlendi. Tüm sonuçlar göz önünde bulundurulduğunda, fonksiyel gıda ambalaj uygulamaları için umut veren fonksiyonel kompozit polimer filmler geliştirilmiştir.
