Abstract
A biocomposite powder comprising 20-95% (w/w) chitin-glucan complex (CGC), and up to 50% (w/w) mannose-containing polysaccharides, wherein the biocomposite powder has a bulk density of 0.5 to 1.0 g/cm3, and wherein greater than 60% (w/w) of the particles of the biocomposite powder have a size below 212 μm.
Claims20
A biocomposite powder comprising 20-95% (w/w) chitin-glucan complex (CGC), and 1-50% (w/w) mannose-containing polysaccharides, wherein the biocomposite powder has a bulk density of 0.8-1.0 g/cm3, a tapped density of 1.0-1.1 g/cm3, a Carr index of 9-20, a stability index of 0.9-1.1 and a flow rate index of 0.9-1.4, and wherein the biocomposite powder is a mixture of at least two fractions of biocomposite powder selected from:
- (a) a fraction of biocomposite powder wherein the particles of the fraction have a size greater than 212 μm;
- (b) a fraction of biocomposite powder wherein the particles of the fraction have a size of 160 to 212 μm;
- (c) a fraction of biocomposite powder wherein the particles of the fraction have a size of 100 to 160 μm;
- (d) a fraction of biocomposite powder wherein the particles of the fraction have a size of 75 to 100 μm;
- (e) a fraction of biocomposite powder wherein the particles of the fraction have a size of 40 to 75 μm;
- and
- (f) a fraction of biocomposite powder wherein the particles of the fraction have a size of less than 40 μm;
- and
- wherein the chitin-glucan complex and mannose-containing polysaccharides are extracted from Komagataella pastoris, and wherein greater than 60% (w/w) of the particles of the biocomposite powder have a size below 212 μm.
