Uniform-sized konjak gulcomannan microspheres and preparation method thereof

The invention relates to uniform-sized konjak gulcomannan microspheres. The average particle size of the microspheres is less than 10 mu m; the content of the konjak gulcomannan in the microspheres is greater than 20% (w/w); the particle size is uniform; and the particle size distribution coefficien...

Beschreibung
Zusammenfassung:	The invention relates to uniform-sized konjak gulcomannan microspheres. The average particle size of the microspheres is less than 10 mu m; the content of the konjak gulcomannan in the microspheres is greater than 20% (w/w); the particle size is uniform; and the particle size distribution coefficient Span value is less than 0.9. The invention further provides a preparation method of the microspheres. According to the invention, the problems that the konjak gulcomannan microspheres of which the particle size is less than 10 mu m are hard to prepare by using the conventional method and the prepared microspheres are not uniform in particle size are solved.
