will speak on
“Flavor Emulsion Fabricated with Lysolecithin for Clear Beverages”
Frick Chemistry Laboratory, Princeton University
Mixer 6:30 pm; Lecture 7:00 pm
Abstract: Flavor extracts of essential oils are frequently used to create optically clear or transparent ready to drink beverages, however, they often lack balanced flavor profiles and mouthfeel which provide the rich-tasting experience consumers are looking for. A shelf-stable flavor emulsion comprising patented lysolecithin as part of the emulsifier system was designed to deliver full flavorings without compromising the visual clarity of a liquid beverage. Phospholipid composition of the lysolecithin was determined by 31P-NMR analysis, which was compared with select commercial lecithin products to better understand differences of their functionality. Performance assessment was carried out by sensory evaluation of the beverage as well as characterizations of the emulsion at zero time and in storage.
