Friends who like to drink soy milk can pay attention to it. To make soybean milk at home is to soak soybeans first and then make soybean milk. However, in the early street stalls selling soybean milk or whole grain soybean milk, raw beans were rarely used to make soybean milk directly. The raw material for making soybean milk is cooked beans or cooked whole grains. The nutritional value of soybean milk made in this way is higher than that made from raw beans?

There are generally two ways to make soybean milk with cooked beans. Cook or bake the beans directly, and most merchants will bake the soybeans. This is because in the baking process, soybeans are heated to produce a chemical reaction, resulting in fragrance, less loss of nutrients, and extremely short processing time, which is more popular among merchants. Therefore, we will smell the thick fragrance of soybean milk in front of the booth where soybean milk or whole grain soybean milk is processed on site. However, when cooked soybeans are heated for the second time, they will lose more nutrients, and protein and fat in soybeans will also denature, so the taste of soybean milk is poor, which affects the commercial value of soybean milk.

Because baked beans are used to make soybean milk, they have a stronger flavor. Does this mean that this is the best way to make soybean milk? The answer is no, when we make soybean milk at home, the soymilk machine usually uses the function of heating. If cooked beans are used to make soybean milk, "secondary heating" will also reduce the content of nutrients.

The simplest way to make soybean milk, the most comprehensive way to preserve nutrition, is actually very simple. Soak soybeans in advance, put them in the freezer of the refrigerator, freeze them for one night, and take them out the next morning to make soybean milk. Frozen soybean can reduce the beany smell of soybean milk and improve the digestibility of protein in soybean milk. Kill two birds with one stone, why not?
