INTECH 29/07/19 Essential Oil Nanoformulations as a Novel Method for Insect Pest Control in Horticulture. 1.
Introduction Horticultural crops are infested with numerous insect pests that cause tremendous economic losses including aphids (Myzus persicae and Aphis gossypii), beet armyworm (Spodoptera exigua), cabbage loopers (Trichoplusia ni), citrus mealybug (Planococcus citri), onion thrips (Thrips tabaci), and greenhouse whitefly (Trialeurodes vaporariorum) . The use of synthetic chemical insecticides to control insect pests poses risks to human health and environment. For this reason, there is an urgent need to apply a range of modern strategies as alternatives for chemical pesticides in order to protect the environment from insecticidal pollution, decrease the regenerating resistance, and increase horticultural crop productivity. Plant natural substances may provide potential alternatives to currently used insect-control agents because these materials constitute a rich source of bioactive chemicals. 2.

JOURNAL OF FISH DISEASES 18/01/18 Involvement of xanthine oxidase inhibition with the antioxidant property of nanoencapsulated Melaleuca alternifolia essential oil in fish experimentally infected with Pseudomonas aeruginosa. Nanoencapsulated Melaleuca alternifolia essential oil (tea tree oil, TTO) is a natural alternative treatment, with 100% therapeutic efficacy in fish experimentally infected with Pseudomonas aeruginosa, and has also potent protective effects linked with antioxidant properties.
However, the pathways responsible for the antioxidant capacity remain unknown. Thus, this study evaluated whether the inhibition of seric xanthine oxidase (XO) activity can be considered a pathway involved in the antioxidant capacity of nanoencapsulated TTO in fish experimentally infected with P. aeruginosa. Seric samples from fish infected with P. aeruginosa showed increased XO activity, as well as increased uric acid and reactive oxygen species (ROS) levels. In contrast, the prophylactic treatment with nanoencapsulated TTO prevented these infection-induced alterations.

PhD thesis, University of Leeds. The objective of this study was firstly to assess the ability of liquid skimmed milk in combination with different concentrations of maltodextrin (MD) to emulsify 5% w/w thyme essential oils (EOs). Secondly, to analyse the chemical composition of the used thyme EOs and further examine the physical properties of some EOs components such as solubility, surface activity and partitioning coefficient.

The crescent interest in the use of essential oils (EOs) as natural antimicrobials and preservatives in the food industry has been driven in the last years by the growing consumers’ demand for natural products with improved microbial safety, and fresh-like organoleptic properties.
Nanoemulsions efficiently contribute to support the use of EOs in foods by increasing their dispersibility in the food areas where microorganisms grow and proliferate, by reducing the impact on the quality attributes of the product, as well as by enhancing their antimicrobial activity.

The aim of this study was to evaluate the effect of process and storage conditions on physical properties and antimicrobial activity of alginate-based films with encapsulated lemongrass essential oil. Films were obtained from film forming emulsions with different droplet sizes (2.9 ± 0.2 μm and 0.43 ± 0.02 μm), containing 1%w/w alginate, 1%w/w sorbitol, 0.75%w/w–1.35%w/w sodium caseinate, 0.5%w/v lemongrass essential oil and 0.02%w/w calcium carbonate. Each film was characterized by physical properties and antimicrobial activity against Escherichia coli and Botrytis cinerea.
Films were evaluated in different storage conditions (75%RH, 4 °C; 75%RH, 20 °C; 11%RH, 4 °C; 11%RH, 20 °C). Droplet sizes of film forming emulsions affected significantly the physical properties and antimicrobial activity of films, being more effective large droplet size. Braz. J.

Bioengineering 2017, 4(3), 74; Encapsulation of Oregano (Origanum onites L.) Essential Oil in β-Cyclodextrin (β-CD): Synthesis and Characterization of the Inclusion Complexes. The aim of the present work was to study the encapsulation of Origanum onites L. essential oil (oregano EO) in β-cyclodextrin (β-CD) inclusion complexes (ICs), using the co-precipitation method. The formed β-CD–oregano EO ICs were characterized by diverse methods, such as Dynamic Light Scattering (DLS), FT-IR spectroscopy, Differential Scanning Calorimetry (DSC), Thermogravimetric Analysis (TGA), Nuclear Magnetic Resonance (NMR) spectroscopy and Scanning Electron Microscopy (SEM). UV-Vis spectroscopy was used for the determination of the inclusion efficacy and the study of the encapsulated oregano EO release profile. The interactions between host (β-CD) and guest (oregano EO) in the formed ICs were proven by the FT-IR, DSC, TG and NMR analyses.

Innovative encapsulation developer, AnaBio Technologies, says it is starting to gain traction in the animal feed sector. Its patented technology uses milk proteins and other biomaterials to create capsules that protect and deliver sensitive ingredients to a target site. “We have been doing a lot research in the area of rumen bypass, encapsulating essential oils and omega-3 oils to prevent degradation in the rumen so they reach the small intestine. “Validation work in this area has involved both in vitro and in vivo research as we have access to herds at the Irish Dairy Institute's research farm,” Stefan Buzoianu, business development manager, animal health and nutrition at AnaBio, told us.
Up to recently, AnaBio had been working, in the main, with large, international infant formula and food companies, working off 12 patents, but now wants to expand its microcapsule encapsulation platform to a greater number of feed applications. The company has been investigating the storage, process and delivery mechanisms of feed ingredients.
