Abstract In this study, edible films composed of 1% (w/v) alginate (Alg) and ylang‐ylang essential oil (YYEO, 0.1%, 0.3%, 0.5%) were fabricated characterized for the first time. The suspension viscosity increased significantly from 255.8 to 290.5 Cp, with a corresponding significant film thickness increase 0.029 0.043 mm. There was also decrease in moisture content (MC%) 30.22 23.93%. Scanning electron microscopy atomic force analyses showed an Alg/YYEO roughness. presence YYEO confirmed by...

Alginate (Alg) films with improved water vapor permeability (WVP), mechanical properties, and ultraviolet (UV) barrier were prepared ylang-ylang oil (YYO) Pickering emulsion (PE). Cellulose nanocrystals (CNCs) used as natural stabilizers to prepare YYO PE. The final coating comprised 1% Alg (alginate), Alg/0.24% CNCs, Alg/0.5% emulsions. impacts of YYO-PE on the properties investigated, their effects post-harvest control mandarins evaluated. Gas chromatography-mass spectrometry (GCMS) was...

In this work, atomic force microscopy (AFM) technique was used to study the microstructure properties of hydroxypropylcellulose/ cinnamaldehyde (CDH) composite biofilm. The solution emulsified by cationic surfactant, lauric arginate (LAE). Zetasizer analysis found that addition CDH-emulsified LAE increased zeta potential HPC-based from -1.31 10.47 (mV). Furthermore, increasing trend showed roughness surface properties. AFM revealed arithmetical mean deviation (Ra) and root square (Rq) HPC...

This study used atomic force microscopy (AFM) to examine the microstructure properties of a composite biofilm made hydroxypropylcellulose (HPC) and cinnamaldehyde (CDH). The zeta potential HPC-based solution was found decrease from -1.31 - 3.24 (mV) with addition CDH-emulsified CDH, according Zetasizer analysis. Additionally, roughness surface showed an increasing trend. AFM analysis indicated that HPC film increased by 1.31 4.01 nm in terms arithmetical mean deviation (Ra) root square (Rq),...
