Aquafaba is the viscous, starchy liquid that is leftover after cooking or canning legumes, most commonly chickpeas (garbanzo beans). The name “aquafaba” is derived from Latin, with “aqua” meaning water and “faba” meaning bean. It is an increasingly popular ingredient in vegan and vegetarian cooking due to its remarkable ability to mimic the functional properties of egg whites. Specifically, when aquafaba is whipped, it can create stable foams and emulsions, much like beaten egg whites, making it a valuable substitute for eggs in various recipes.

The key properties of aquafaba that make it an excellent egg replacement in cooking and baking include its emulsification capabilities, foam formation, and the ability to gel when heated. These properties allow it to be used in a wide range of dishes, from meringues and mayonnaise to cakes and ice creams, providing a versatile and plant-based and healthier alternative to eggs.

Aquafaba has gained popularity in the vegan and vegetarian communities for its versatility, as well as its potential to reduce food waste by making use of an ingredient that is often discarded. It has also shown promise in reducing the environmental impact of food production, as it allows for the creation of egg-like textures and structures without relying on animal agriculture.

What is Aquafaba made up of?

Aquafaba is primarily composed of water, soluble plant proteins, starches, and small amounts of minerals. The specific composition can vary depending on the source of the aquafaba, as it is typically derived from cooking or canning legumes such as chickpeas (garbanzo beans). Here’s a breakdown of the key components:

Water: The majority of aquafaba’s composition is water, typically around 90% or more. This high water content provides the liquid base for aquafaba.

Soluble Proteins: Aquafaba contains soluble proteins, such as globulins and albumins. These proteins are the essential components that give aquafaba its unique properties, allowing it to mimic the functional properties of egg whites when whipped.

Starches: Starches, which are complex carbohydrates, are also present in aquafaba. These starches contribute to the thickening and gelation properties of aquafaba when it is heated, making it suitable for certain culinary applications.

Minerals: Aquafaba contains small amounts of minerals, including potassium, calcium, and magnesium, which can influence its taste and behaviour in recipes.

It’s important to note that the specific composition of aquafaba can vary depending on factors such as the type of legume used (chickpeas, black beans, etc.), the cooking method, and whether the liquid comes from canned or cooked legumes. Despite these variations, the soluble proteins in aquafaba are the primary contributors to its ability to create foams and emulsions, making it a valuable egg white substitute in vegan and vegetarian cooking.

Aquafaba can be easily obtained at home by using the liquid that results from cooking or canning legumes, such as chickpeas, or by using the liquid from a can of beans. Here’s how you can find and make aquafaba:

Canned Beans: The most convenient way to obtain aquafaba is by purchasing canned beans, particularly chickpeas (garbanzo beans). When you open a can of beans, you’ll find the liquid inside, which is the aquafaba. Make sure to choose canned beans with no added salt or seasonings if you want a neutral-tasting aquafaba.

Cooked Legumes: If you prefer to use cooked legumes, you can simply cook your own chickpeas, black beans, lentils, or other legumes at home. The liquid remaining from cooking these legumes is your homemade aquafaba.

As for pricing, the cost of aquafaba can vary depending on where you live and where you purchase it. Here are some general guidelines:

  1. Canned Beans: Canned beans are readily available in most grocery stores, and the price can vary based on the brand, location, and the type of beans. A can of beans typically costs a few dollars, and you get both the beans and the aquafaba.
  2. Cooked Legumes: If you cook your own legumes, the cost will depend on the price of the dried legumes and the energy used for cooking. Dried legumes are generally affordable and can be bought in bulk for even more savings.

It’s worth noting that aquafaba is a by-product of using legumes, and its cost is relatively low. As a result, it’s an economical and sustainable option for creating vegan and vegetarian dishes, and it can help reduce food waste by making use of an ingredient that is often discarded. Making aquafaba at home by cooking your own legumes is usually the most cost-effective option.
