Preparation and characterization of sodium selenite/sodium alginate microcapsules
Journal Title: 广东农业科学 - Year 2018, Vol 45, Issue 12
Abstract
"Microencapsulation was an effective method to prevent the sodium selenite (Na2SeO3) from being oxidized by environmental factors. By using sodium alginate as the shell, Nano-calcium carbonate as the cross linker, Na2SeO3 was encapsulated by emulsification/internal gelation to obtain sodium selenite/ sodium alginate microcapsules (SSSAM). The composition and structure were characterized by Fourier infrared (FTIR) and X-ray diffraction (XRD), respectively. The result showed that Na2SeO3 was embedded into SSSAM in the form of amorphous state. When the mass ratio of Nano-CaCO3 was 1/2, the oil-water volume ratio was 4∶1, Span 80 mass fraction 3%, emulsification for 40 min, cross-linking for 15 min, the loading content (LC) of Na2SeO3 and encapsulation efficiency (EE) of SSSAM were 16.2% and 52.7%, respectively."
