Making plant-based better

Date: 07.12.2020Source: NIZO


NIZO has published a webcast on fermentation of plant-based dairy alternatives. Renske Janssen, Project Manager Protein Technology, pointes out that plant-based ingredients, namely plant protein, cannot replace animal protein directly. Therefore, plant-based ingredients must be altered in order to develop the desired properties in the finished product. Fermentation is a natural way to achieve this.

First, the right lactic acid bacteria strains must be identified by screening and selection. Suitable strains then can be adapted to the new substrate by fermention for a 1,000 generations.Plant protein is precipidated at the isoelectric point using the adapted bacteria strains. Right selection of strains can also help reduce off-lavours or create the desired glavour and texture.

In the webcast, Janssen demonstrates all this using a plant-based cream cheese alternative as example. Lactic bacteria strains add dairy functionalities to the plant based substrate, based on a selection according to their EPS productioon and proteolytic characteristis.
