How is Oat Milk Made

How is Oat Milk Made?

Before you can drink oat milk, you must understand how it is made. Here is a step-by-step guide to making oat milk at home:

Soak the oats: To soak the oats, add 2 cups of water to a bowl with 1 cup of rolled oats. Give the oats to soak for at least two hours—or even the entire night. The oats become softer and are simpler to combine as a result.

Blend the oats: Drain the soaked oats, then add 4 cups of water to a blender. At this point, you can also incorporate any extra ingredients, including flavors or sweeteners. The mixture should be smooth after 1-2 minutes of high-speed blending.

Strain the mixture: Place a cheesecloth or fine-mesh strainer over a big basin or pitcher to drain the mixture. Pour the oat mixture over the strainer gradually while pressing it through with a spoon or spatula. The remaining sediments in the strainer should be discarded.

Chill and serve: Transfer the oat milk to a jar or bottle, then put it in the fridge to chill before serving. Shake vigorously before using. In addition to being consumed on its own, oat milk can be used as a milk substitute in baking, coffee, and tea.

Note: By blending in more or less water, you can change the consistency of your oat milk. Instead of rolled oats, you can use steel-cut oats, though it can take longer for them to soak and blend. Before soaking the oats, it’s a good idea to rinse them to get rid of any dirt or debris.

Here you will learn about the ingredients in oat milk, heat processing, and the addition of carrageenan to it. You will also learn about how to store it. After you know all these facts, you can make a delicious beverage.

Ingredients in Oat Milk

Oat milk is a great plant-based drink, but you should check the ingredients before buying it. Look for milk alternatives fortified with protein, fat, and other essential nutrients. They should also be low in artificial colors and flavors. Choose unsweetened varieties to cut the sugar.

Be aware that some oat milk contains added sugar. Look for the “added sugar” row on the nutrition label. This is a sign that oat milk is processed in a way that isn’t healthy for you. Some brands also add an extra step during the production process that keeps the oats from gelling. This creates less “slim” milk.

Other oat kinds of milk contain oils. This help mimics the fat content in cow’s milk. Some brands, like Oatly, add canola oil to their blend. While canola oil has gotten a bad rap recently, it contains heart-healthy fats.

Process of Heat Processing

The process of heat processing oat milk involves drying the oat pulp, separating it, and heating it to 60degC. It is then mixed with a homogenizer, which breaks down the fat droplets into uniform droplets, providing a creamy mouthfeel. It is then bottled or packed into cartons.

Oats are a grain that grows on a plant. Its leaves and stalks are removed before they are milled to create flour. Hot water, usually around 60degC/140degF, is poured over the flour to extract all its nutrients. The result is a dense liquid containing high fiber, protein, and dietary fiber levels.

Oats can be cooked separately or mixed with other grains. They can be used in breakfast cereals, batters, extruded products, and beverages. They are low in calories, have high fiber content, and have more calcium than cow’s milk.

Carrageenan in Oat Milk

The chemical compound carrageenan has been linked to cancer and other diseases. Studies have shown it can trigger an immune response and aggravate gut inflammation. It has been implicated in several GI disorders, including ulcerative colitis. Some researchers believe it can also cause intestinal ulcers and cancer. However, the evidence is mixed, and more research is needed to determine its risk to human health.

Oat milk can be consumed cold or steamed. Using steamed oat milk when combined with coffee and similar beverages is advisable. When consumed cold, the milk will become thick and change color. In addition, the shelf life of oat milk is four to seven days.

Oat milk is a great alternative for those who have dietary restrictions and do not want to consume cow’s milk. Oat milk has many health benefits, including heart health and cholesterol. People with intolerances and allergies can also benefit from oat milk.

Storage of Oat Milk

When it comes to oat milk, it’s important to know the proper way to store it. Oat milk may develop mold or slime if left unattended for too long. The milk may also change color or smell bad. If you notice these changes, you should immediately discard the milk.

Oat milk is made from strained oats blended with water. Depending on the manufacturer, it can contain oil to make it smooth and a sweetener to enhance its flavor. Different companies make slightly different versions of oat milk, and the difference in the ingredients will affect the shelf life. Some brands recommend using the milk within four days, while others say you can keep it for up to 10 days.

When storing oat milk, you should keep it in a cool, dry place. The ambient room temperature will affect its shelf life, so keep the container refrigerated. A glass jar is ideal for storing the product.
