Interactions in food - Bridging interaction
3 important questions on Interactions in food - Bridging interaction
When does bridging flocculation occur?
When the polysaccharide/polymer concentration is not high enough to cover the entire surface of the particle.
What happens with bridging flocculation?
There are not enough polymers present to cover the entire surface of the particles. The polymer may link to 2 or more particles, forming a 'bridge' between the particles. A cluster of particles can be formed --> bridging flocculation
What happens to the flocculates formed after bridging flocculation?
They sediment (if they are heavier) or cream (if they are lighter).
