“…Such emulsions consist of oil droplets coated by thin polymer shells and suspended in an aqueous medium [ 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 ], so they can also be treated as dispersions of nanocapsules. They may serve as carriers of corrosion inhibitors, pesticides, and antimicrobial agents [ 27 , 28 , 29 ]. Moreover, they are suitable for food additives (e.g., milk derivatives, beverages), cosmetics (e.g., lotions, gels) and dietary supplements and drugs (e.g., vitamins, chemotherapeutics), enhancing the uptake of an active compound by a factor of even hundreds in comparison to the microemulsion systems.…”

Recent developments in the fabrication of core-shell polymer nanocapsules, as well as their current and future applications, are reported here. Special attention is paid to the newly introduced surfactant-free fabrication method of aqueous dispersions of nanocapsules with hydrophobic liquid cores stabilized by amphiphilic copolymers. Various approaches to the efficient stabilization of such vehicles, tailoring their cores and shells for the fabrication of multifunctional, navigable nanocarriers and/or nanoreactors useful in various fields, are discussed. The emphasis is placed on biomedical applications of polymer nanocapsules, including the delivery of poorly soluble active compounds and contrast agents, as well as their use as theranostic platforms. Other methods of fabrication of polymer-based nanocapsules are briefly presented and compared in the context of their biomedical applications.

“…Recently, many food and nutrition researchers have focused on the fortification of foods with health‐promoting bioactive ingredients, such as nutrients or nutraceuticals, so as to enhance their ability to improve human health and performance (Choi, Kim, Cho, Hwang, & Kim, 2011; McClements, 2007; Wang et al., 2008). A wide variety of bioactive ingredients have been examined for this purpose, including macronutrients (proteins, carbohydrates, and lipids), micronutrients (vitamins and minerals), and nutraceuticals (carotenoids, geraniol, curcumin, and resveratrol) (de Vos, Faas, Spasojevic, & Sikkema, 2010; Dey, Ghosh, Ghosh, Koley, & Dhar, 2012; Syed, Banerjee, & Sarkar, 2020; Wang et al., 2008; Xiong, Li, Warner, & Fang, 2020). Table 2 summarizes some of the bioactive ingredients that have been encapsulated within nanoemulsion‐based delivery systems and the nutritional benefits claimed for them.…”

Recently, there has been growing interest in implementing innovative nanoscience‐based technologies to improve the health, safety, and quality of food products. A major thrust in this area has been to use nanoemulsions because they can easily be formulated with existing food ingredients and technologies. In particular, oil‐in‐water nanoemulsions, which consist of small oil droplets (<200 nm) dispersed in water, are being utilized as delivery systems for various hydrophobic substances in foods, including nutrients, nutraceuticals, antioxidants, antimicrobials, colors, and flavors. In this article, we focus on the application of nanoemulsion‐based delivery systems for improving the quality, safety, nutritional profile, and sensory attributes of muscle foods, such as meat and fish. The article also critically reviews the formulation and fabrication of food‐grade nanoemulsions, their potential benefits and limitations in muscle food systems.

“…This agglomeration trend can be estimated using Zeta potential values: stable systems have Zeta potential values between −30 and −100 mV, where 0 mV represents the maximum agglomeration and precipitation. The decrease in the ζ-potential values would assist for the long-term stability of the emulsions [10]. Figure 1 shows the values of the inhibition zones of analysed strains in the presence of the natural preparations, presented as an average of three determinations, as well as the standard deviation for emulsions and positive control.…”

Natural Preparations Based on Orange, Bergamot and Clove Essential Oils and Their Chemical Compounds as Antimicrobial Agents

et al. 2020

Since ancient times complementary therapies have been based on the use of medicinal plants, natural preparations and essential oils in the treatment of various diseases. Their use in medical practice is recommended in view of their low toxicity, pharmacological properties and economic impact. This paper aims to test the antimicrobial effect of natural preparation based on clove, orange and bergamot essential oils on a wide range of microorganisms that cause infections in humans including: Streptococcus pyogenes, Staphylococcus aureus, Shigella flexneri, Candida parapsilosis, Candida albicans, Pseudomonas aeruginosa, Escherichia coli, Salmonella typhimurium and Haemophilus influenza. Three natural preparations such as one-component emulsions: clove (ECEO), bergamote (EBEO), and orange (EOEO), three binary: E(BEO/CEO), E(BEO/OEO), E(CEO/OEO) and a tertiary emulsion E(OEO/BEO/CEO) were obtained, characterized and tested for antimicrobial effects. Also, the synergistic/antagonistic effects, generated by the presence of the main chemical compounds, were studied in order to recommend a preparation with optimal antimicrobial activity. The obtained results underline the fact that the monocomponent emulsion ECEO shows antimicrobial activity, while EOEO and EBEO do not inhibit the development of the analyzed strains. In binary or tertiary emulsions E(BEO/CEO), E(CEO/OEO) and E(OEO/ BEO/CEO) the antimicrobial effect of clove oil is potentiated due to the synergism exerted by the chemical compounds of essential oils.
