Oat milk is one of the most nutritious plant milk options out there. It is very low in fat, but actually contains more calcium per serving than cow’s milk. It’s also a great source of Vitamin A and iron. One serving of oat milk can contain 36% of the daily recommended calcium intake, whereas whole milk only provides 28%. This is a great way to get some calcium in if you’re vegan or lactose intolerant.
In commercial oat milk, the production process starts with milling, followed by enzyming to break down the oat starches into smaller components. The bran is then separated from the oats, leaving behind the loose fibres. Then, if relevant other flavourings and ingredients are added, such as vitamins. The milk is then sterilised before being packaged.
Similar technology and equipment or plant is also applicable to rice milk, chia milk and quinoa milk.
