Sucrose esters are sensitive for high acidity. You can work with the following indicative schedule:
- pH ≥ 4: Sucrose esters can be used without problems
- pH 3 - 4: If possible, adjust the processing: prepare the emulsion prior to adding the acid ingredients. In that way the sucrose esters are partly dissolved in the oil (droplets) and less sensitive for acid.
- pH ≤ 3: Sucrose esters will slowly degrade to their components, sugar and fatty acids, and lose their emulsifying capacity.
