“…The accumulation of such constituents in the lipid bilayer of the cytoplasmic membrane will give it a permeability characteristic (BERTINI et al, 2005;ANDRADE et al, 2012). Similar results for ZOEO were found by Silva (2018), in which S. aureus showed a MIC of 4.7 μl / mL, while for E. coli the MIC was 2.3 μl / mL. By isolating E. coli and S. aureus from patients' biological materials, Silva et al (2009) proved that ginger had a higher efficiency over E.…”

Zingiber officinale Roscoe and Curcuma longa L. (Zingiberaceae) essential oils were obtained by the hydrodistillation method. The oils offered yields of 0.120% and 0.044% respectively. GC-MS analyzes allowed the identification of 11 constituents in the Curcuma longa essential oil, with major components: ar-turmerone (36.8%), β-tumerone (32.3%) and curlone (19,2%) For the Zingiber officinale essential oil 19 constituents were identified, being: neral (22.9%), zingiberene (15.5%) and geranial (14.9%) the main components. The result of the toxicity test showed significant activity against Artemia salina for both oils. The dose values required to eliminate 50% (LC50) of the larvae were 100 µg / mL for Z. officinale and 25 µg / mL for C. longa. The antioxidant activity was performed against DPPH free radical. The most significant activity was exhibited by Z. officinale with an IC50 value of 215.8 µg / mL. The antibacterial assay with Z. officinale oil showed efficacy against S. aureus and E. coli, with MIC values of ≥ 213.3 μg / mL and 85.3 μg / mL respectively. For C. longa, MIC values ≥ 1024 μg / mL were observed for both bacteria tested. Modulation with aminoglycoside antibiotics showed synergism of C. longa oil combined with amikacin against S. aureus, with a decrease in MIC from 1024 μg / mL to 14.7 μg / mL. Meanwhile, the Zingiber officinale oil obtained a MIC reduction to 6.7 μg / mL, demonstrating greater efficacy. The results observed here demonstrate the biological potential of the species as cytotoxic and antimicrobial.

“…So far a wide variety of essential oils have been electrospun, including cinnamon [39][40][41][42][43][44], oregano [45][46][47][48], peppermint [44,[49][50][51][52], clove [41,[53][54][55][56][57], thyme [58][59][60][61], lavender [62][63][64], eucalyptus [65], ginger [66], tea tree [67,68], Manuka [68], black pepper [69], and sage [69]. This review focuses on works that report the addition of EOs to polymeric solutions before conducting the electrospinning process.…”

The extensive and sometimes unregulated use of synthetic chemicals, such as drugs, preservatives, and pesticides, is posing big threats to global health, the environment, and food security. This has stimulated the research of new strategies to deal with bacterial infections in animals and humans and to eradicate pests. Plant extracts, particularly essential oils, have recently emerged as valid alternatives to synthetic drugs, due to their properties which include antibacterial, antifungal, anti-inflammatory, antioxidant, and insecticidal activity. This review discusses the current research on the use of electrospinning to encapsulate essential oils into polymeric nanofibres and achieve controlled release of these bioactive compounds, while protecting them from degradation. The works here analysed demonstrate that the electrospinning process is an effective strategy to preserve the properties of essential oils and create bioactive membranes for biomedical, pharmaceutical, and food packaging applications.

“…Soy protein isolate (SPI) is mainly composed of proteins isolated from soybean and it is widely used in the food industry for its functional properties (Silva et al, 2018). SPI is here proposed as an excellent carrier material due to the well-known emulsifying and stabilizing properties when O/W emulsions are formed (McClements and Li, 2010) However, SPI is a globular protein with low solubility in organic solvents and poor mechanical properties, which complicates fiber formation through electrospinning (Cho et al, 2012).…”

In this work, emulsion electrospinning was used to develop an active internal coating for food packaging applications. Specifically, the antioxidant molecule β-carotene, was encapsulated in a mixture of soy protein isolate (SPI) and polyvinyl alcohol (PVA) which was directly electrospun onto a polyhydroxybutyrate-co-valerate (PHB92/PHV8) film. An annealing treatment was applied to improve the adhesion of the electrospun mat onto the packaging film, which contributed to modulate the release of the active compound. Stable SPI:PVA emulsions (with a 50:50 ratio) were developed using soybean oil (SBO) as carrier of the hydrophobic -carotene. The encapsulation efficiency of β-carotene in the electrospun SPI:PVA fibers was 65.0% ± 2.6 %, being 51.4 % ± 0.9 % effectively incorporated into their cores. Finally, the in-vitro release assay of the antioxidant in soybean oil, which simulates fatty foods, demonstrated that the heat treatment (anneling) contributed to a slower and more sustained released of the bioactive compound.
