This guide will delve into these other ingredients and explain why each is added.

Common oat milk additives on a table

1️⃣ Stabilisers

Stabilisers are used to maintain the integrity of oat milk by preventing ingredient separation.

By thickening the liquid, stabiliser can also improve mouthfeel and ensure a smooth, homogeneous texture.

2️⃣ Acidity Regulators

Ingredients You Might See:

  • Potassium Carbonate
  • Dipotassium Phosphate

Acidity regulators are used to control the pH level of oat milk, thus extending its shelf life and preventing spoilage.

They are also useful in preventing curdling when oat milk is mixed with acidic substances like coffee.

3️⃣ Emulsifiers

Ingredients You Might See:

  • Soy Lecithin
  • Sunflower Lecithin

Emulsifiers facilitate the blending of oil and water in oat milk, preventing oil separation and ensuring a consistent, well-integrated mixture.

Are all additives bad?

While a short and simple ingredient list is often preferred, it's important to note that not all additives are inherently negative.

Many additives serve valid functions like enhancing taste, texture, and shelf life and ensuring food safety. 

However, like any ingredient, their safety depends on factors such as the type and amount used, as well as individual sensitivities.
