A biorefinery process comprising the steps of:
- (i) introducing wet citrus material;
- (ii) subjecting the citrus material to microwave assisted steam distillation;
- (iii) isolating d-limonene, leaving a first citrus material residue;
- (iv) subjecting the first citrus material residue to an organic solvent extraction;
- (v) isolating flavour compounds, flavonoids and/or monosaccharides, leaving a second citrus material residue;
- (vi) subjecting the second citrus material residue to a hydrothermal microwave treatment;
- (vii) isolating pectin and mesoporous cellulose.
