Encapsulation of thyme essential oil (Thymus vulgaris) in chia mucilage (Salvia hispanica L.) and its application in fresh pork sausage.

This study evaluated the application of thyme essential oil (TEO) encapsulated in chia mucilage in meat sausages as a partial or total substitute for sodium nitrate and nitrite. We assessed three capsules produced with different concentrations of TEO (3.5 %, 7.

Anthocyanin-rich grape pomace extract encapsulated in protein fibers: Colorimetric profile, in vitro release, thermal resistance, and biological activities.

Red wine grape pomace is an important source of bioactive compounds with biological activities of interest. Grape pomace extract can be encapsulated in ultrafine fibers using the electrospinning technique. Encapsulation is used to increase stability and protect the phenolic compounds in the extract.

Starch-octenyl succinic anhydride nanoemulsions with clove and white thyme essential oils: In vitro antifungal activity and application on orange (Citrus sinensis cv. Salustiana) preservation.

Starch modified by octenyl succinic anhydride (OSA) is a polysaccharide that can be used as a stabilizer in the development of emulsions added with essential oils (EOs). The objective of this study was to develop nanoemulsions based on starch-OSA containing clove essential oil (CEO) and white thyme essential oil (WTEO) and a proportional mixture of the two EOs (CWTEO) using high-pressure homogenization. The emulsions were characterized by particle size, zeta potential, polydispersity index, stability during 150 days, and antifungal activity, with inhibition of mycelial growth, against the fungus Penicillium digitatum.

Chemical Composition, Antimicrobial and Antioxidant Activities of Broccoli, Kale, and Cauliflower Extracts.

The brassicas have the potential to prevent chronic non-communicable diseases and it is proposed to evaluate the chemical composition, antioxidant and antimicrobial potential of broccoli, cabbage and extracts. The extracts were prepared and characterized and the antioxidant potential was evaluated against three radicals while the antimicrobial potential was analyzed using three techniques against four bacteria. The extracts have glucosinolates and phenolic compounds in their composition, and effectively inhibit the 2,2-diphenyl-1-picrylhydrazyl radical.

Valorisation of olive pomace: phenolic prospecting and biological potential.

Phenolic compounds were extracted from biphasic olive pomace and their biological potential was characterised. Two different extracts were prepared, E1 (40% methanol) and E2 (80% methanol), both subjected to agitation (180 min) and 70 °C. LC-ESI-qTOF-MS was used for individual quantification of the extracted phenolic compounds.
