Egg substitutes

language culture Maturity 5-7 Next article →

Egg substitutes are food products designed to replace real eggs in cooking and baking. These products serve many different purposes for various types of cooks. Some people must avoid eggs because they have an egg allergy. Others choose to follow a vegan or vegetarian diet that omits eggs. Some consumers use substitutes due to concerns about animal welfare or the environmental burden of egg farming. There are also safety concerns regarding Salmonella contamination in raw eggs. Because some industry labels remain confusing or misleading, many people choose substitutes to ensure they are eating what they intend to eat.

Commercial egg substitutes use various scientific and biological processes to mimic eggs. For example, THE EVERY Company uses a fermentation process to produce bioidentical egg whites. This means the product is designed to be identical to the real thing at a molecular level. Another company, JUST, Inc., creates egg-free products like cookie dough and mayonnaise substitutes. They achieve this by using protein extracted from the yellow pea. Other companies use micro-algae and micro-organisms, such as baker's yeast or brewer's yeast, to create egg white substitutes. There are also specific liquid products like The Vegg, which acts as a vegan liquid egg yolk. This product is made from nutritional yeast flakes, sodium alginate, kala namak, and beta-carotene.

It is important to distinguish between different types of egg-related products. Many commercial substitutes are entirely devoid of animal products, making them vegan and cholesterol-free. However, some products are not true substitutes. For instance, Egg Beaters is a substitute for whole or fresh eggs from a shell, but it is not a complete egg substitute because it consists mainly of egg whites. Other commercial options include Egg Replacer, which is a specific mixture of ingredients. This mixture contains potato starch, tapioca flour, leavening agents like calcium lactate and cream of tartar, cellulose gum, and modified cellulose.

Home cooks can also create their own substitutes using common pantry items. The choice of ingredient depends on which specific function of the egg must be replicated. If a cook needs to replicate the whipped structural loft and moisture of egg whites, they can use aquafaba. Aquafaba is the liquid and solutes left over after cooking chickpeas or from a commercial can of chickpeas. For recipes that require a meaty structure and texture, such as quiches or custards, tofu is a common choice. If a cook wants to make a fluffier dish like an omelette, they should use silken tofu instead.

In sweet baked goods and desserts, fruit purées are often used to replace the moisture and binding properties of an egg. To replace one large whisked egg, a cook can use a specific amount of banana, canned pumpkin, canned squash, applesauce, or puréed prunes. These fruits provide the necessary structure, though they will add their own flavor to the recipe. Ground seeds can also serve as binding agents or thickeners. Using ground chia seeds is effective, but cooks should use white chia seeds if they want to maintain the original color of the recipe. Dark chia seeds can darken the final product.

Other ingredients can provide both texture and nutrition. Chickpea flour combined with water or another liquid is equivalent to one egg. This method provides the texture and color of eggs while adding protein, folate, iron, calcium, and various vitamins and minerals. However, there is a practical drawback to using chickpea flour. It can taste quite bad before it is cooked. If a cook is making an unbaked batter that will be eaten raw, they should choose flax or chia seeds instead. These seeds provide the necessary binding without altering the taste of the recipe.

Egg substitutes connect various fields of science, nutrition, and culinary art. They involve biotechnology through fermentation and micro-algae use. They also involve food science to balance moisture, binding, and structural loft. By using these different tools, cooks can navigate dietary restrictions and safety concerns. Whether using complex bioidentical proteins or simple fruit purées, these substitutes allow for a wide range of culinary possibilities. They ensure that many different types of people can participate in the shared experience of cooking and eating.
