Summary:
Potato pulp is produced in large amounts as waste material from potato starch production. Utilizing this waste material for production of a novel high value product has been investigated in this thesis, and the high content of pectin in potato pulp was utilized for this purpose. A gentle enzymatic extraction procedure for isolation of the pectic fragment rhamnogalacturonan I (RG I) was developed. The developed procedure enabled isolation of RG I in undegraded form and in high yields. The isolated RG I and modified versions of RG I were hereafter investigated for different functionalities and application potentials. RG I was investigated as a potential prebiotic, as coating material for surgical meshes, and as a potential anti-cancer agent. RG I exhibited excellent potentials in all of the investigated application areas, and the results clearly demonstrate that there are great possibilities in upgrading potato pulp from waste material to raw material
