We all agree that coffee is one of the most important beverages to be enjoyed in everyday life. However, there are some people who experience an issue with the taste of coffee when consumed in soy milk.

If you’ve ever wondered why your soy lattes have curdled in your coffee, we have the answer for you.

What is soy milk?

Soy milk is one of the most popular non-dairy milk alternatives on the market, and for good reason: it’s delicious, versatile and a great way to save money.

But that doesn’t mean soy milk is as natural as the label on the carton might suggest. Soy milk is made from soybeans—the same beans that are used to make tofu, soy sauce and the nut butter known as edamame.

Soy milk has many flavors and is used in many food recipes. It is also used in certain beauty products and cooking. Soy milk is not the same as regular milk and is not lactose-free.

Reasons why soy milk curdles

This article is about reasons why the soy milk curdles. As you know, soy milk has become a popular beverage recently, and it can be found in your local grocery store.

So, what is curdling? Curdling is the process of separating the fat and water in the soy milk, and it is often done by heating the milk to a certain temperature. When the milk reaches this temperature, the fat and water separate, and the fat becomes butter-like in appearance.

It’s a nutritional and tasty drink, especially for vegetarians. You don’t need to add sugar to soy milk because it already has a sweet taste, and you can also add fruits and flavors to it.

So, here it is;

  • As you may know, soy milk is the byproduct of pressing soybeans. At various stages of processing, the beans go through a series of steps that depend on the type of bean being processed.

During the first step, the beans are blended and heated. At this stage, the beans begin to form a protein-rich cream-like substance.

  • Soy milk curdle when it gets hot. Why? Because soy milk has protein molecules in it, and proteins don’t like to be hot.
  • It’s a milk that is made from soybeans, but the milk is not allowed to curdle in the same way cows milk does, because the soybeans have been processed differently by having their proteins broken down into smaller pieces by boiling.
  • The first is the presence of milk enzymes called lipolytic and proteolytic enzymes in the milk, which are present in raw milk, cow’s milk, and plain soy milk, but not to the same extent in the processed varieties.

How to stop soy milk curdling?

Soy milk is a great source of protein, but if you’re not careful, it can curdle, or separate into a solid mass, when it is heated. What causes this process?

It all has to do with the way soy proteins are linked together, and how they form curd. When you make a soy milk, you use either a soy milk concentrate or a soy milk with added calcium.

milk that is not heated properly will separate because the proteins in the milk do not form a strong enough bond to hold everything together.

The solution is to heat the soy milk slowly, and stir constantly to prevent the curd from forming. 

Is it fine to drink curdled soy milk in coffee?

Soy milk is more commonly known as soymilk, and it is a fairly popular milk substitute, especially in the Asian community.

Soy milk contains calcium and protein, which is why it’s used in many recipes as a substitute for cow’s milk.

However, it’s made by fermenting soybeans into a ripened liquid, and that’s why it has a slightly different taste than milk.

Some people complain that the taste is too strong, but soy milk is relatively high in protein and calcium, so it can be used in various kinds of food and drinks.
