4. Conclusion
Coconut kernel residue from coconut milk and coconut virgin oil are good sources of dietary fibre except for the high fat content in coconut milk residue. Coconut cell wall polysaccharides isolated from coconut virgin oil residue using different solvents had different cell wall polysaccharide contents. The chemical and functional properties of coconut kernel residue and cell wall isolations are comparable to other corresponding food residues and cell wall isolations. The metal ion concentration of coconut kernel residues and cell wall isolations are higher than the metal ion concentrations of other food residues and cell wall isolations. Harnessing the potential of these by-products as a dietary fibre could be a health benefit and a great economic boost to the coconut industry.
