Article Abstract
This study aimed to verify the level of repellent and mortality effect of two chemical substances (DEET and 2-undecanone) and seven essential oils (EOs), , , , , , , and . The storage pests , , and were exposed to various concentrations in an olfactometer-and-mortality test. The effects were recorded 24-48-72 h after the treatments were applied. , , and were found to have significant repellence effects. A substantial lethal effect was observed for , , and . We also found that even if the most efficient EOs were diluted to low concentrations, they still produced repellent and mortality effects. The presented results indicate that and were the most effective against and simultaneously, and showed high activity against . All of these efficient EOs could be applied as effective bio-control agents in various stored conditions.
Miller is a highly valued aromatic and nutritious plant. The unique compositions of its essential oil make it more valuable in the flavor, fragrance, and medicinal industries. However, the potential of superheated steam distillation for obtaining essential oils from its seeds has not been explored in detail.
Cold atmospheric pressure plasma (CAPP) comprises an ensemble of ionized gas, neutral particles, and/or reactive species. Electricity is frequently used to produce CAPP via a variety of techniques, including plasma jets, corona discharges, dielectric barrier discharges, and glow discharges. The type and flow rates of the carrier gas(es), temperature, pressure, and vacuum can all be altered to control the desired properties of the CAPP.
Thymol is a phenol monoterpene that is naturally derived from cymene and is an isomer of carvacrol. It constitutes a significant portion (10%-64%) of the essential oils found in thyme ( L., Lamiaceae), a medicinal plant renowned for its therapeutic properties.

There is growing concern about the potential risks posed by synthetic additives in industrial products, such as foods, cosmetics, agrochemicals, and personal care products. Many plant-derived essential oils (EOs) have been shown to exhibit excellent antibacterial, antifungal, antiviral, and antioxidant activities, and may therefore be used as natural preservatives in these applications. However, most EOs have relatively low water solubility and are prone to chemical degradation during storage.

Recent explorations into cinnamaldehyde (CIN) have identified its potential as a natural preservative, particularly when incorporated into active packaging to enhance the shelf-life of fruits and vegetables. This study explores the use of cellulose nanofiber (CNF)-stabilized Pickering emulsions as a novel delivery system for essential oils, demonstrating broad applicability in food preservation strategies. We employ CNF as Pickering stabilizers to effectively emulsify and encapsulate CIN, investigating the influence of tannic acid (TA) concentrations on the stability of these emulsions.
