Most Common Additives/ Gums / Hydrocolloids
Egg albumen foams/gels
- Foam ability and foam stability are one of the most important functionalities of egg albumen. However, the use of commercially available egg albumin for foaming poses a few disadvantages, such as limited pH and ionic strength variety for the adequate performance
- According to Kampf et al. (2003), prolonged increasing whipping time increases the number of small bubbles and decreases the number of larger bubbles without much effect on their sizes. The whipping time affects the consistency of the foam or its mechanical strength.
Methylcellulose in foam-mat drying, Methylcellulose origin and food uses
- Cellulose molecules can combine to form fibrous crystalline bundles that are highly insoluble and impermeable to water.
- MC’s heat-gelling ability makes it possible to eliminate pre-frying from the manufacturing process of battered foods.
- Temperature and pH do not significantly affect the water retention of powdered cellulose.
Gum Arabic in foam-mat drying
- Gum Arabic is also known as gum acacia. Gum Arabic also contains small amounts of protein, an important part of the structure. For example, a combination of Arabic gum and other gums, such as (tragacanth gum) at a specific ratio, can produce a thin emulsion with minimum viscosity of high quality, shelf and stability [3].
