3 min read

With the global plant-based milk market projected to grow significantly, more people are asking: what is vegan milk made of?. At its core, vegan milk is an emulsion created by blending a plant-based source with water, then filtering the solids, providing a dairy-free alternative for a variety of uses.

Quick Summary

An in-depth look at the diverse ingredients that form vegan milk, including base components like nuts, grains, and legumes, plus thickeners, stabilizers, and fortifications. Find out how the source plant influences texture and nutritional content.

Key Points

Core Ingredients: Vegan milk is primarily made from blended nuts (almonds, cashews), grains (oats, rice), or legumes (soybeans, peas) mixed with water.
Commercial Additives: Store-bought versions often contain stabilizers like gums, added oils for texture, and sweeteners for flavor.
Nutritional Fortification: Many plant-based milks are fortified with added vitamins and minerals, including calcium, vitamin D, and B12, to improve their nutritional profile.
Protein Content Varies: Soy and pea milks are known for their high protein content, while nut and rice milks are generally much lower.
Allergen Awareness: Individuals with allergies should always check labels, as cross-contamination can occur during processing, and plant-based milks contain different common allergens like nuts and soy.
Environmental Impact: Production methods for vegan milk, particularly those using soy and pea, generally have a smaller environmental footprint compared to dairy milk.

Core Ingredients: How Vegan Milk is Made

At its simplest, vegan milk is created by combining a plant-based source with water and then straining the solids. However, the process differs slightly depending on the base ingredient, and commercial milks often include additional components to enhance flavor, texture, and nutritional value.

Nuts and Seeds

Nut and seed milks are created by soaking raw ingredients, blending them with water, and straining the liquid to remove the pulp.

Almonds: A popular, low-calorie choice, almond milk is made from almonds and water, often with added sweeteners and fortifications. It is naturally high in Vitamin E but low in protein.
Cashews: Yields a creamy, rich milk without the need for straining. Cashew milk is a good source of magnesium and potassium.
Hemp Seeds: Hemp milk is rich in omega-3 fatty acids and complete proteins. Its flavor is often described as earthy.
Sesame Seeds: Homemade sesame milk can be a good source of minerals.

Grains

Grain-based milks offer different textures and are popular for their neutral flavors.

Oats: Oat milk has surged in popularity due to its creamy texture and suitability for coffee. It is made from soaked oats and water. To prevent sliminess, it's recommended to use hot water when blending.
Rice: One of the earliest plant-based milks, rice milk is often naturally sweet and low in allergens. It is typically made from rice syrup, rice flour, and water in industrial processes.

Legumes

Legumes provide a high-protein base for milk alternatives, with a nutritional profile often closer to dairy milk.

Soybeans: One of the oldest and most widespread vegan milks, soy milk is made from soybeans and water. It boasts a high protein content and is often fortified to mimic dairy's nutritional value.
Peas: Pea milk is a newer innovation derived from yellow peas. It is praised for its high protein content and low environmental impact.

Other Sources

Coconuts: The flesh of coconuts is grated, mixed with water, and pressed to extract the milk. Coconut milk varies greatly in thickness and is a staple in many cuisines.

Common Additives and Fortifications

Commercial vegan milks often include more than just the base ingredient and water. These additives serve various purposes, from improving texture to boosting nutrition.

Stabilizers and Emulsifiers: Ingredients like guar gum, gellan gum, and carrageenan are added to prevent separation and create a smooth, creamy mouthfeel.
Sweeteners and Flavorings: To balance flavors, manufacturers may add sweeteners like cane sugar, maple syrup, or dates, as well as natural flavorings like vanilla.
Oils: Some brands add vegetable oils, such as sunflower or canola oil, to enhance creaminess and improve consistency.
Fortifications: Vitamins and minerals, particularly calcium, vitamin D, and vitamin B12, are commonly added to fortify plant-based milks and match the nutritional profile of dairy.

Conclusion: The Diverse World of Vegan Milk

Vegan milk is not a single product but a diverse category of plant-based beverages, each with unique ingredients, flavors, and applications. From the high-protein content of soy and pea milk to the low-calorie nature of almond milk and the creamy richness of coconut milk, consumers can find a dairy-free alternative that fits their dietary needs and taste preferences. While homemade versions offer purity, commercial options provide convenience and nutritional fortifications. Ultimately, understanding what goes into each type of vegan milk empowers consumers to make informed choices that align with their health and environmental goals.
