POTATO PROTEIN ISOLATES

摘要

The present invention relates to a process for obtaining a potato protein fraction using a specific absorbent. Specifically, the invention relates to the carrier material, which comprises a specific polymeric material, functionalised with suitable ligands. By the use of a functionalised support carrier according to the present invention, a potato protein fraction can be obtained with higher effectiveness.

主权项

1. A process for the isolation of a native potato protein fraction from potato juice, comprising the steps of
a) adjusting the pH of the potato juice to 4.0-6.5; b) contacting the potato juice with a functionalised support carrier having pores wherein at least 90% of the pores have a pore diameter between 10 and 200 nm, and wherein the carrier is functionalised with a hydrophobic, mixed-mode ligand having a pKa of 2.5-5 which ligand is coupled to the carrier through an S- or O-atom; c) desorbing the potato protein fraction from the functionalised support carrier by elution; and d) optionally concentrating and/or drying the potato protein fraction.
