Laboratory demonstrations of emulsion stability

In laboratory demonstrations, several emulsions based on sunflower and soybean oil were stabilised with different Borregaard biopolymers.

After preparing the emulsions, they were stored at 40°C for up to 3 months, and the average droplet sizes recorded regularly. Storage conditions were demanding. The emulsions were allowed to cream, and between each measurement, a relatively dense-packed cream layer formed.

Key takeaways:

• Droplet size distributions did not change under difficult storage conditions
• Good stability in systems with intimate droplet to droplet contact
