What is A Novel Strategy to Fabricate Stable Oil Foams with Sucrose Ester Surfactant about?
## Hypothesis: Can a mixture of sucrose ester surfactant in vegetable oil be aerated to yield stable oleofoams? is foaming achievable from one-phase molecular solutions and/or two-phase crystal dispersions? does cooling a foam after formation induce surfactant crystallisation and enhance foam stability? ## Experiments: Concentrating on extra virgin olive oil, we first study the effect of aeration temperature and surfactant concentration on foamability and foam stability of mixtures cooled from a one-phase oil solution. based on this, we introduce a strategy to increase foam stability by rapidly cooling foam prepared at high temperature which induces surfactant crystallisation in situ. differential scanning calorimetry, x-ray diffraction, infra-red spectroscopy, surface tension and rheology are used to elucidate the mechanisms. ## Findings: Unlike previous reports, both foamability and foam stability decrease upon decreasing the aeration temperature into the two-phase region containing surfactant crystals. at high temperature in the one-phase region, substantial foaming is achieved (over-run 170%) within minutes of whipping but foams ultimately collapse within a week. we show that s
