Why do consumers ask for bakery products that are free from egg?
Health- and sustainability-conscious consumers are driving the “free-from” trend by asking for egg-free alternatives. Numerous recent public health concerns, such as avian influenza and fipronil contamination, have also increased the importance of egg replacement. Moreover, egg is a costly ingredient with considerable supply and price fluctuations. Being able to partially substitute eggs helps to buffer raw material shortages while guaranteeing a constant quality of baked goods.
What is the challenge?
Replacing eggs can be very challenging, as they are an essential, multi-functional component in many fine bakery products. Egg has a major impact on fine baked goods, from the processability of the batter to the determination of quality parameters such as volume, texture, taste and shelf-life.
Is there a solution for 100% egg replacement without quality deficits?
Yes, there is an innovative solution for replacing up to 100% egg in cake and other fine bakery products: α-cyclodextrin. This naturally occurring oligosaccharide is made from starch and can be obtained from WACKER under the trade CAVAMAX® W6. In combination with water and protein (either plant or dairy based), α-cyclodextrin represents a solution for up to 100% egg replacement in ready-to-use powder mixes or final baked goods that still fulfill the quality and sensory expectations of consumers.
Advantages of using α-cyclodextrin:
- α-Cyclodextrin allows manufacturers to replace egg without compromising on product quality and can simply be added to powder premixes for easy handling.
- In comparison to egg, which can be difficult to handle, α-cyclodextrin allows producers to employ a leaner HACCP management.
- Because it has no major influence on batter pH or viscosity, α-cyclodextrin can be used on existing equipment and production lines.
- Replacing egg by α-cyclodextrin can reduce costs by up to 40% and additionally provides a buffer for seasonal egg-price deviations.
α-Cyclodextrin improves batter aeration and the stability of fat droplets and gas cells. The synergy of α-cyclodextrin with proteins stabilizes the texture and retains the moistness of the final baked good. The graphic on the left summarizes the functionality of α-cyclodextrin (CAVAMAX® W6) in bakery products.
How to replace eggs
The combination of α-cyclodextrin, protein (dairy or plant-based) and water can be used to replace some or all of the egg in a formulation. This works for liquid egg as well as for powdered egg. In which products can α-cyclodextrin replace egg? The proven solution has already been tested in:
- Pound cake
- Sponge cake
- Layer cake
- Yeast leavened applications
- Further applications are possible

Analysis of texture and taste verifies excellent quality with α-cyclodextrin
Eliminating egg in a cake typically results in reduced volume and elasticity. α-Cyclodextrin compensates for the loss in elasticity, as shown in the graph below. The sensory parameters of cake made with α-cyclodextrin are likewise very similar to those of the egg-containing control. Variations in color can easily be adjusted by adding beta-carotene.
