Effect of Oil-Droplet Diameter on Lipid Oxidation in O/W Emulsions

Encapsulation of curcumin within oil-in-water emulsions prepared by premix membrane emulsification: Impact of droplet size and carrier oil on the chemical stability of curcumin

“…This can be explained by the limited oxygen present in the sample, the amounts of primary oxidation products were similar whatever the droplet sizes of emulsions (Lethuaut et al, 2002). This result is in agreement with previous studies that investigated the effect of emulsion droplet size on lipid oxidation (Osborn & Akoh, 2004;Walker et al, 2015;Roppongi et al, 2021). However, some studies reported that increasing the emulsion droplet sizes led to a better oxidative stability of emulsions due to the decrease in surface area of droplets, which is exposed to the aqueous phase (Azuma et al, 2009;Yalçinöz & Erçelebi, 2020).…”

Changes in lipid compositions of krill oil emulsions during storage, a role of ultrasound treatment and the possible process of lipid migration

“…Although some studies provided approaches and suggestions for establishing an emulsion system of krill oil, they paid little attention to phase migration of lipids in an emulsion system, especially krill oil emulsions. In O/W emulsions, oxygen in the water phase will transfer to the oil–water interface so that it can participate in oxidation reaction of lipids (Roppongi et al ., 2021). Unlike triglyceride‐type emulsions, krill oil rich in phospholipids seemed to perform different phenomena in the processing and storage of emulsions.…”
