“…Therefore, the main interactions that occur between electrospun gelatin nanofiber and eggplant peel extract are hydrogen bonds of intermolecular hydrogen bonding type. Kumar [40] mentions that when the −NH group of a peptide is involved in a hydrogen bond, its position changes, showing itself at a lower frequency, which may be the case in this study, when a decrease in amine band II is observed regarding control. Likewise, Li [41] performed a characterization of active gelatin-based films with the addition of natural antioxidants.…”

This study describes the preparation and characterization of eggplant peel extract-loaded electrospun gelatin nanofiber and study of its in vitro release. Results obtained by scanning electron microscopy (SEM) and transmission electronic microscopy (TEM) micrograph revealed that eggplant peel extract-loaded electrospun gelatin nanofiber is in nanometric range with an average diameter 606.7 ± 184.5 and 643.6 ± 186.7 nm for 20 and 33.3 mg mL−1 of extract addition, respectively. Moreover, the incorporation of extract improved morphology by being smooth, homogeneous, and without account formation compared to nanofibers without extract (control). Fourier transform-infrared (FT-IR) spectra indicated that interaction exists between electrospun gelatin nanofiber and eggplant peel extract by hydrogen bond interactions, mainly. Electrospun gelatin nanofibers showed encapsulation efficiency greater than 90% of extract and a maximum release of 95 and 80% for the medium at pH 1.5 and 7.5, respectively. Therefore, the electrospinning technique is a good alternative for the conservation of bioactive compounds present in the eggplant peel through electrospun gelatin nanofiber.

“…This is probably due to the strong phenol–protein interaction between PPE and SPI that reduced the free volume of the matrix, causing a reinforcing effect that weakened the molecular motility of film components (Xiao et al, 2021). Another possibility was that the development of crystalline structure in the SPI/PPE nanocomposite films by accumulating the concentration of PPE led to the reduced mobility of the polymeric chains in the film matrix (Kumar et al, 2021). Additionally, there was no significant difference in the SPI/PPE nanocomposite films at the ratio of 1:2 and 1:3.…”

“…The SPI/PPE nanocomposite films showed higher onset decomposition temperatures than that of control nanocomposite film, indicating better thermal stability. The thermal stability of the SPI/PPE nanocomposite films was significantly improved due to the cross‐linking and hydrogen bonding interactions between SPI and PPE (Kumar et al, 2021). As shown in Figure 6b, the nanocomposite film at SPI/PPE ratio of 1:2 showed the highest onset decomposition temperature, and that the residual mass at 800°C reached 15.13%, indicating the strongest interaction within the polymer chains.…”

Interactions between components in film‐forming solution affected the physicochemical properties of active packaging. A series of soy protein isolate (SPI)‐based nanocomposite films reinforced with zinc oxide nanoparticles and different pitaya peel extract (PPE) levels were fabricated by photocatalysis. Results showed that the tensile strength, oxygen and water vapor barrier properties, thermal stability and DPPH scavenging activity were substantially improved, but the elongation at break and transmittance decreased with the proportion of PPE increased due to the formation of a more compact film structure caused by the crosslinking of PPE and SPI, particularly at the SPI/PPE ratio of 1:2. However, excessive PPE was not conducive to the integrity and continuity of film structures. The SPI/PPE films had more favorable anti‐bacterial activities against Staphylococcus aureus than Vibrio parahaemolyticus. Therefore, our finding suggested that photocatalytic SPI/PPE nanocomposite film is an interesting alternative to obtain materials with antimicrobial and antioxidant properties. Novelty impact statement Pitaya peel extract (PPE) was added into soy protein isolate (SPI)/ZnO film matrix through photocatalysis. Addition of PPE resulted in compact inner microstructures of the films. SPI‐PPE conjugate greatly improved the antibacterial and antioxidant properties of the films.

“…The results showed improvement in film tensile strength as well as comparable chemical resistivity and thermal properties. The use of pineapple peel extract as the natural antioxidant agent was implemented to produce polyvinyl alcohol-starch films [123]. There are enhancements in the thermal and antioxidant properties of the produced films with pineapple peel extract.…”

Pineapple waste accounts for a significant part of waste accumulated in landfill which will further contribute to the release of greenhouse gases. With the rising pineapple demands worldwide, the abundance of pineapple waste and its disposal techniques are a major concern. Exploiting the pineapple waste into valuable products could be the most sustainable way of managing these residues due to their useful properties and compositions. In this review, we concentrated on producing useful products from on-farm pineapple waste and processing waste. Bioenergy is the most suitable option for green energy to encounter the increasing demand for renewable energy and promotes sustainable development for agricultural waste. The presence of protease enzyme in pineapple waste makes it a suitable raw material for bromelain production. The high cellulose content present in pineapple waste has a potential for the production of cellulose nanocrystals, biodegradable packaging and bio-adsorbent, and can potentially be applied in the polymer, food and textile industries. Other than that, it is also a suitable substrate for the production of wine, vinegar and organic acid due to its high sugar content, especially from the peel wastes. The potentials of bioenergy production through biofuels (bioethanol, biobutanol and biodiesel) and biogas (biomethane and biohydrogen) were also assessed. The commercial use of pineapples is also highlighted. Despite the opportunities, future perspectives and challenges concerning pineapple waste utilisation to value-added goods were also addressed. Pineapple waste conversions have shown to reduce waste generation, and the products derived from the conversion would support the waste-to-wealth concept.
