Fabrication, characterisation and antimicrobial activity of electrospun Plantago psyllium L. seed gum/gelatine nanofibres incorporated with Cuminum cyminum essential oil nanoemulsion

Abstract

Summary Plantago psyllium L. seed gum (PPSG)/gelatine nanocomposites containing Cuminum cyminum essential oil (CCEO) were prepared via electrospinning, and the antibacterial properties of the electrospun nanofibres were assessed against Staphylococcus aureus. The nanoemulsion was prepared by adding CCEO to the PPSG/gelatine mixture and sonicated. Uniform nanofibres resulted from the nanoemulsion containing 1.5% PPSG, 8% gelatine and 3% CCEO, and no chemical reactions between the components of the electrospun nanofibres were detected. Growth inhibition zone diameter indicated that the electrospun nanofibres containing at least 3% CCEO had the most significant inhibitory effect on the growth of S. aureus. The electrospun PPSG/gelatine‐CCEO nanocomposites are capable of being used as a biodegradable material in food packaging as well as in edible coatings for the preservation of food products.

Electrospun Cactus Mucilage/Poly(vinyl alcohol) Nanofibers as a Novel Wall Material for Dill Seed Essential Oil (Anethum graveolens L.) Encapsulation: Release and Antibacterial Activities

“…cyminum essential oil, which also has an inhibitory effect on the growth of S. aureus . Furthermore, the improved antimicrobial activity of nanofibers loaded with essential oil is significantly due to the existence of antibacterial active compounds in DSEO, essentially d -limonene, apiol, piperitone, and carvone (Table ).…”

“…These findings confirm that the DSEO release occurred in the nanofibers, suggesting that the blending of CM with PVA promotes a more controlled release. The CM/PVA electrospun fibers are considered better carriers for essential oils than the electrospun poly(lactic acid) nanofiber loaded with Zingiber cassumunar Roxb essential oil, reaching their maximum release of about 80% after 12 h, and almost 50% of the nanoemulsified Cuminum cyminum essential oil was released from the electrospun Plantago psyllium L. seed gum/gelatin nanofibers within the first 12 h and reached zero after 36 h . This means that the CM/PVA/DSEO electrospun nanofibers exhibit a slow release process for essential oils and are suitable for innovative active packaging and pharmaceutical uses.…”

“…CM/ PVA electrospun nanofibers loaded with 4% DSEO had the highest antibacterial activity compared to that reported for electrospun Plantago psyllium L. seed gum/gelatin nanofibers incorporated with 3% C. cyminum essential oil, which also has an inhibitory effect on the growth of S. aureus. 66 Furthermore, the improved antimicrobial activity of nanofibers loaded with essential oil is significantly due to the existence of antibacterial active compounds in DSEO, essentially D-limonene, apiol, piperitone, and carvone (Table 1). D-limonene is the main compound present in DSEO; it has great applications in antibacterial and food preservation due to its bactericidal activity, safety, and low toxicity.…”
