However, product purification can be challenging due to the abundance of host cell proteins (HCPs) in raw plant extracts and which have to be removed. Here we report different heat treatment methods, e. g. based on leaf blanching. This can facilitate subsequent downstream processing, and thus has the potential to reduce production costs.de570journal article
