RuBisCO (Ribulose-1,5-bisphosphate carboxylase oxygenase) is the main protein in green leaves, and the most abundant protein in the world. Rubisco is water soluble and has a good nutritional value and very good functionalities (foaming, gelling etc.)

Lihme Protein Solutions has participated in the project “Food-grade protein extraction from sugar beet leaves from sugar production” together with Danish Technological Institute and Nordic Sugar. The idea is to utilize the residual side stream from sugar production (the sugar beet leaves) to get a food-grade protein product.

The current practice is to separate RuBisCo by heating and/or acidic precipitation techniques. Our technique uses milder conditions which retains the native characteristics and functionalities of the protein.
