Effects of Span surfactants on the preparation and properties of fish oil-loaded sodium alginate-stabilized emulsions and calcium alginate-stabilized capsules

Tween emulsifiers improved alginate-based dispersions and ionic crosslinked milli-sized capsules

“…The alginate/Tween 80 emulsions exhibited different behaviors (emulsion fluidity and creaming) to the alginate/Span 80 emulsions in our previous work 18 . It was interesting that no hollow holes with similar sizes to the 10-mm homogenizer head were present in the middle of all the emulsions (Images were not shown).…”

“…2 . The freshly prepared emulsions were in milk white, which was similar to the fish oil-loaded alginate/Span-stabilized emulsions 18 . When the Tween 80 concentrations were 10 (Fig.…”

“…It was interesting that no hollow holes with similar sizes to the 10-mm homogenizer head were present in the middle of all the emulsions (Images were not shown). The fluidity of alginate/Span 80 emulsions might decrease with the increasing concentrations of Span 80 and sodium alginate, and therefore the emulsions had hollow holes at relatively high emulsifier concentrations 18 . The interaction between Tween 80 and sodium alginate did not increase the fluidity of the emulsions even at high amounts of the emulsifier, which was different from Span 80.…”

“…Surfactants could improve the properties of alginate-based oil encapsulation preparations. Our recent work suggested that different Span surfactants (Span 20, 40, 60, and 80) had different effects on the fish oil-loaded alginate-based dispersions and capsules 18 . Tween series are typical small molecular surfactants for emulsion stabilization 19 , 20 .…”

The effects of Lactobacillus reuteri microcapsules on radiation-induced brain injury by regulating the gut microenvironment

“…Sodium alginate (SA) microcapsules of probiotics were prepared referring to the literature with minor modifications. 29 L. reuteri was cultured in MRS broth and incubated anaerobically at 37 °C for 24 h. L. reuteri cells (5 × 10 9 CFU) were collected by centrifugation for 10 min at 10 000 g , and then 5 mL of 2% (w/v) SA aqueous solution was added. The SA suspension with L. reuteri was mixed with olive oil containing 0.1% (v/v) Tween 80 and then emulsified by stirring at 600 rpm for 15 min (water : oil, 1 : 1).…”
