Current egg replacements on the market are derived from various ingredients such as soy, flaxseed, potato starch, tapioca flour, chia seeds, and chickpeas. While some of these alternatives can mimic certain functionalities of eggs—like binding, moisture retention, or adding bulk—they often fall short in other crucial aspects. Eggs are known to fulfill over 20 essential roles in baking, including foaming, ingredient binding, and thickening, making it challenging for any substitute to replicate all these functions effectively.
“Beyond their nutritional value, egg ingredients contribute significant functional properties to baked goods,” stated Bill Gilbert, principal food technologist at Cargill, in an interview with Food Business News. “It’s impossible to replace eggs with any single ingredient while still achieving comparable nutrition and functionality.” Despite this challenge, some innovative companies are eager to explore solutions. For instance, Hampton Creek is set to launch its long-anticipated Just Scramble, an eggless liquid replacement, next year.
Another interesting alternative comes from Fiberstar Inc., which offers a citrus fiber egg replacement product. This option, rich in pectin, can be utilized to enhance eggs rather than completely substitute them. Additionally, these egg replacements are pasteurized and typically have a longer shelf life than conventional eggs. However, they are currently more costly. That said, it is reasonable to assume that vegans and those who choose to avoid animal-based foods are willing to pay the premium. Moreover, utilizing egg substitutes can provide manufacturers with a buffer against future disruptions in supply caused by events like avian influenza outbreaks.
Interestingly, research indicates that the absorption rate of calcium citrate may also be influenced by the presence of these egg replacements in baked goods, further showcasing the complex interactions in food formulations. Consumers and manufacturers alike are beginning to recognize the potential benefits of these alternatives, particularly as they relate to health and sustainability. As the market evolves, the demand for effective egg substitutes that can maintain the absorption rate of calcium citrate and other nutritional attributes will likely grow.
