What is Oat Milk?

Oat milk is a popular, vegan-friendly milk replacement for dairy products. It is manufactured with water by soaking and mixing stainless steel or rolled oats and then tightening via a chopping chamber to remove the milk.

Moreover, it includes beta-glucan, a soluble fibre that might be beneficial for cardiac health. Oat milk may be found in most food shops or online because of its rising popularity.

For instance, the method of Oatley is five-step: They first milk an oat/water combination and add enzymes to break the starch. Then the loose oat coats (also called oat bran) are removed from the mix, and the fibre remains (also known as beta-glucans). Before pasteurizing and packaging the whole blend, they will be able to add vitamins and minerals such as calcium and vitamin D. The three are nutritionally equal, although oat milk is greater in carbohydrates. It should also be noted that oat milk is caloric rather than sweetened almond and coconut milk.

What is Soy Milk?

Soy milk is a cultural and commercial commodity that predates all other substitute milk, including oat milk.

Since the beginning of the twentieth century, soy milk has travelled from Asia to European and American supermarket shops.

In the early 1990s, when Rickard Oster invented oat milk, the first example of an oat-crop beverage. Oster studied lactose intolerance and sustainable food systems at Lund University in Lund, Sweden, when he created the drink.

However, certain doubts arise from the prominent health benefits of soy. Over the years 2017–2019, sales of oat milk in the United States were up tenfold, with a three times rise in worldwide sales claimed by one major producer, Oatley.

Soy milk is a plant-based drink produced by heating soybeans in water, then grinding and pushing to remove the insoluble fibres.
