“…Vitamin C and titratable acids degradation was mainly caused by the exposure of respiration and ripeness. Similar results were also observed by Rong et al, (2019) concluded that the weight loss, shrinkage index, firmness, and total sugar of passion fruit packaged with poly(lactic acid)/poly (butylene adipate -co-terephthalate) films had no significant differences compared with PE films during 21 days (p > 0.05) preservation at 20°C. Peninah et al, (2014) indicated that active bags can prolong the shelf life by maintaining quality attributes and external appearance of purple passion fruits and hence extend their marketing period.…”

The effects of propionic acid and mixed wax (bees and carnauba wax; MW) on total microorganisms and quality of purple passion fruit at ambient temperature 25±2°C and 70%–80% relative humidity were studied. The fruits were dipped in propionic acid solution at the concentrations of 0.15%; 0.25%; 0.35% (v/v) and 0.2% carbendazim, then coated with MW 2.5% by hand. After drying, they were stored at 25 ± 2 °C for 18 days. Uncoated fruits were preserved at the same temperature as control. The determination parameters were isolation and identification of microorganisms, total microorganism, percentage of fruit decay, weight loss, total soluble solids content (TSS), total sugars, titratable acidity, and ascorbic acid content; interval time was every 3 days of storage time. The results showed that identified two kinds of microorganism were Fusarium moniliforme var. subglutinans and Fusarium oxysporum Schlecht. The concentration of 0.25% propionic acid solution and MW coating could reduce the percentage of weight loss, fruit decay, and total microorganisms for 18 days of storage time. Moreover, this combination could remain chemical qualities, as TSS, total sugars, titratable acidity, ascorbic acid content in 18 days of storage time.

“…The increase of total sugar content was mainly due to maturation and changing titratable acids. Rong Zhang, 2019 shown that the sharpest increase of total sugar was changed PLA/PABT-and PE-packaged samples (8.25% and 8.55%, respectively) after 15 days. The content of vitamin C (Fig.…”

“…4,5 As one of the most produced biodegradable plastics, poly(butylene adipate-co-terephthalate) (PBAT) exhibits high elongation at break, excellent flexibility and good processability comparable to polyethylene, 6,7 thus showing great application prospect in agriculture and packaging. [8][9][10] However, the disadvantages of high cost, [11][12][13][14] short shelf life, 8,15,16 poor weather and water resistance [17][18][19] and poor gas barrier properties 20,21 still limit its wide application.…”

Poly(butylene adipate‐co‐terephthalate) (PBAT) is a type of synthetic biodegradable thermoplastic copolyester with comparable mechanical properties to polyethylene, but the application of PBAT is limited by factors such as high cost, short shelf life, poor weather and water resistance. In order to develop PBAT composites with high performance and low cost, lignin‐modified PBAT biocomposites with enhanced tensile strength were prepared via in‐situ construction of interfacial dynamic bonds. Zinc stearate and epoxy soybean oil were introduced as the interfacial modifiers to construct dynamic bonds between lignin and PBAT, so as to improve the interfacial compatibility. The results demonstrated that the lignin/PBAT biocomposite with interface modifiers reached the maximum tensile strength of 36.7 MPa and an elongation at break of 725.3% at the lignin content of 5 wt%, with the tensile strength achieved 5% improvement on the basis of pure PBAT (34.9 MPa and 717.6%). When the lignin content was increased to 10 wt%, the lignin/PBAT biocomposite with interfacial modifiers still maintained the tensile strength of 35.4 MPa and the elongation at break of 627.8%, which was 82% and 31% higher than that of the directly compounded sample without interfacial modifiers, respectively. Even when the content of lignin loading increased to 20 and 30 wt%, the mechanical properties of the composites were still significantly improved by adding modifiers. The hydrophobicity of the composite was also improved after in‐situ interfacial modification. The strategy demonstrated in this work provides an effective reference for the development of lignin/PBAT composites with high performance but low cost.

“…According to a previous article, the incorporation of a high-toughness compatible biopolymer such as polybutylene adipate-co-terephthalate (PBAT) into the PLA matrix can effectively improve the material’s toughness and flexibility [ 14 ]. This high-toughness polymer has been commonly used for packaging or agricultural purposes [ 15 , 16 ]. Only a few studies have mentioned it as a biomaterial for tissue regenerative applications.…”

Preparation and Characterization of Porous Poly(Lactic Acid)/Poly(Butylene Adipate-Co-Terephthalate) (PLA/PBAT) Scaffold with Polydopamine-Assisted Biomineralization for Bone Regeneration

The development of scaffolds that simultaneously provide porous architectures and osteogenic properties is the major challenge in tissue engineering. Herein, a scaffold with high porosity and well interconnected networks, namely poly(lactic acid)/poly(butylene adipate-co-terephthalate) (PLA/PBAT), was fabricated using the gas foaming/ammonium bicarbonate particulate leaching technique. Mussel-inspired polydopamine (PDA)-assisted biomineralization generated by two-step simple soaking in dopamine solution and 10× SBF-like solution was performed to improve the material’s osteogenicity. Highly porous scaffolds available in less organized opened cell structures with diameters ranging from 10 µm to 100 µm and 200 µm to 500 µm were successfully prepared. The well interconnected porous architectures were observed through the whole thickness of the scaffold. The even deposition of the organic–inorganic bioactive mineralized layer composed of PDA and nano-scale hydroxyapatite (HA) crystals on the scaffold surface was evidenced by scanning electron microscopy (SEM), energy-dispersive X-ray analysis (EDX), Fourier transform infrared spectroscopy (FTIR), and X-ray diffraction (XRD). The developed scaffold exhibited high total porosity (84.17 ± 1.29%), a lower surface contact angle (θ = 45.7 ± 5.9°), lower material degradation rate (7.63 ± 2.56%), and a high level of material biocompatibility. The MTT assay and Alizarin Red S staining (ARS) confirmed its osteogenic enhancement property toward human osteoblast-like cells (MG-63). These results clarified that the developed porous PLA/PBAT scaffold with PDA-assisted biomineralization exhibited good potential for application as a biomaterial for bone tissue regeneration and hard tissue engineering.
