“…It was contributed by the aloe vera gel consisting of 90% of water content. However, incorporating curcumin negligibly reduces the moisture content of bio-films because the curcumin particles improve the hydrophobicity of the composite films by intermolecular interaction through hydrogen bonding between the components [47]. The bioactive compound curcumin can reduce film's moisture content due to its low affinity with water, promoting film humidity reduction [38].…”

This study was performed to develop and characterize a bio-film composed of Aloe vera (Aloe barbadensis), green banana Saba (Musa acuminata x balbisiana), and curcumin for the detection of Fe2+ ions. Cross-linking interaction between banana starch-aloe vera gel and banana starch-curcumin enhanced l the sensing performance of the composite film towards divalent metal ions of Fe2+. The morphological structure of the Aloe vera-banana starch-curcumin composite revealed a smooth and compact surface without cracks and some heterogeneity when observed under Scanning Electron Microscopy (SEM). The thickness, density, color property, opacity, biodegradation, moisture content, water-solubility, water absorption, swelling degree, and water vapor permeability of bio-films were measured. The incorporation of aloe vera gel and curcumin particles onto the banana starch film has successfully improved the film properties. The formation of the curcumin-ferrum (II) complex has triggered the film to transform color from yellow to greenish-brown after interaction with Fe2+ ions that exhibit an accuracy of 101.11% within a swift reaction time. Good linearity (R2 = 0.9845) of response on colorimetric analysis was also obtained in Fe2+ ions concentration that ranges from 0 to 100 ppm, with a limit of detection and quantification found at 27.84 ppm and 92.81 ppm, respectively. In this context, the film was highly selective towards Fe2+ ions because no changes of color occur through naked eye observation when films interact with other metal ions, including Fe3+, Pb2+, Ni2+, Cd2+, and Cu2+. Thus, these findings encourage curcumin-based starch films as sensing materials to detect Fe2+ ions in the field of food and agriculture.

“…Interest in biodegradable packaging has been increasing in response to the growing awareness of the environmental damage caused by accumulated petroleum-derived plastic waste. [1][2][3] In recent years, biodegradable natural polymers have been extensively researched [4][5][6] and, in certain applications, non-biodegradable synthetic polymers have been replaced by natural, or synthetic, biodegradable polymers. 7 Poly(vinyl alcohol) (PVA), a biodegradable synthetic polymer, can be dissolved in hot water and used as a watersoluble film.…”

A series of blend films comprised 88% hydrolyzed poly(vinyl alcohol) (PVA) with native cassava starch (NCS), high‐oxidized cassava starch (HCS), and pre‐gelatinized cassava starch (PCS) was prepared via solution casting. The blends were plasticized with glycerol or glycerol‐sorbitol mixture. The structure of each blend film was characterized by Fourier‐transform infrared spectroscopy and X‐ray diffraction analysis. Cross‐sections of the PVA/HCS and PVA/PCS blend films, imaged by scanning electron microscopy, indicated a PVA‐rich/starch‐rich bilayer structure, irrespective of the type of plasticizer in the blend. High degree of swelling of the blend films resulted to the fast degradation. All blend films were completely degraded in soil after 4 days. Significantly, we identified a number of blend films showed greater strength and elongation at break than low density polyethylene, suggesting that these environmentally benign blends could be ideal candidates for widespread applications currently dominated by petroleum‐derived products.

“…Polysaccharide-based polymers such as epoxy, polyesters, starch and soy-based polymers, cellulose, levan have been by fermentation process (Reddy et al, 2013). These polymers can be used in food packaging industries due to their excellent biodegradability, thermal properties, nutritional qualities, oxygen and water barrier properties and lower cost (Arayaphan et al, 2020). The most commonly used biopolymers are polylactic acid, polyhydroxyalkanoates, xanthan, sodium alginate, dextran, pullulan, chitosan, gelatin, etc.…”

Aim: To develop and characterize laboratory-made pullulan blended film using pullulan obtained from yeast-like fungus Aureobasidium pullulans mixed with gelatin and sodium alginate. Methodology: The laboratory-made pullulan blended (LPB) and standard pullulan blend (SPB) films were prepared by the solution casting method. Physical and mechanical properties were performed to examine the moisture content, film thickness, film solubility, tensile strength and elongation at break. Fourier transform infrared spectroscopy, X-ray diffraction, and field emission scanning electron microscope techniques were performed to analyze the interaction between the polymeric blends. Results: The polymeric blends had excellent miscibility and compatibility with the pullulan. The addition of glycerol to pullulan blended films improved the solubilization time in water at 125 sec. The blending ratio of pullulan, sodium alginate and gelatin led to lower rates of thickness, moisture content and higher elongation at break. Field Emission-SEM and FTIR analyses revealed that both sodium alginate and gelatin were compatible with pullulan. XRD results confirmed that pullulan blended films possess an amorphous structure that readily absorbs the moisture content. The biodegradability test confirmed the potential use of pullulan blended films as biodegradable plastic film. Interpretation: The laboratory-made pullulan blended films exhibited improved mechanical and water barrier properties due to strong interaction between the plasticizer and polymer matrixes which enhances the flexibility of pullulan blended films for the fabrication of biodegradable plastic film. Key words: Aureobasidium pullulans, Biodegradable plastic film, Microscopic techniques, Pullulan blended films
