Development Of Nanoemulsion-Based Delivery Systems For Evaluation Of Triglycerides Bioactivity In Caernohabditis Elegans, Jose D. Colmenares
Development Of Nanoemulsion-Based Delivery Systems For Evaluation Of Triglycerides Bioactivity In Caernohabditis Elegans, Jose D. Colmenares
Masters Theses
Digestion and absorption of bioactive free fatty acids have been studied using the nematode Caernohabditis elegans (C. elegans). However, fatty acids mostly occur in foods in the form of triglycerides, which are highly hydrophobic molecules with low water-solubility, thereby making it difficult to study the fate of ingested fatty acids in C. elegans. The purpose of this research was to develop a method to deliver hydrophobic bioactives, including triglycerides, into C. elegans. Nanoemulsions containing triglyceride nanoparticles were prepared by sonication, and nanoparticle ingestion was confirmed by optical and confocal microscopy, and quantified by spectrometry. Changes in fatty …
Synergistic Interfacial Properties Of Casein And Small Molecule Surfactants For Fabrication Of Essential Oil Nanoemulsions, Dan Su
Masters Theses
Nanoemulsions of essential oils are important for delivery of flavors and antimicrobial preservatives in food systems. The overall goal of this work was to study the formation and properties of essential oil nanoemulsions fabricated with sodium caseinate (NaCas) or its hydrolysates and small molecule surfactants (SMSs). The first group of lemon oil nanoemulsion was prepared with NaCas and Tween 20 using a phase inversion temperature (PIT) method. The combination of NaCas and Tween 20 reduced the turbidity and droplet dimension of emulsions than using them individually. Heating at 90 °C for >1 h resulted in transparent nanoemulsions for samples with …
