How to make soybean milk at home

Soak soybeans in water for about 3-8 hours, and the soaked soybeans are ellipsoidal, then grind the soybeans or crush them with a pulverizer, and then separate the soybean dregs with gauze to obtain raw soybean milk. Boil raw soybean milk with water for 5 to 10 minutes, and serve. Raw soybean milk must be boiled completely to destroy soybean soap alkali which can cause allergy. Soybean residue is a by-product of squeezing soybean milk and can also be eaten.

There is also a high-speed grinding method, which does not need filtration, because there is no need to filter residues, so that soybean fibers can be retained.

Do you want to soak beans first when you beat soybean milk?

Since the emergence of soymilk machine without soaking beans in the market, people have been wondering one thing: Do you need to soak beans in advance to make good soymilk? Is the quality of soybean milk made with and without beans the same? Which would be better?

1. First of all, it sounds convenient not to soak beans, but it actually takes longer. It only takes a minute or two to soak beans the night before, and after soaking, you can quickly make soybean milk; If you don't soak beans, the procedure after the soymilk machine is started will be extended a lot, and it will take some time to heat up to promote the water absorption and softening of beans, which is actually more time-consuming. Therefore, whether from the perspective of low-carbon environmental protection or from the perspective of saving time by drinking soy milk in the morning, soaking beans is obviously more beneficial.

2. Secondly, soaking beans can improve the pulp yield. Compared with no soaking, after soaking beans 12 hours, the yield of soybean milk can be increased by 10%, while the yield of bean dregs is decreased. Within 12 hour, the longer the soaking time, the higher the pulp yield. In other words, soaking beans is beneficial to tissue fragmentation, which can make soybean milk more delicate and release nutrients better. In terms of taste, soy milk made from soaked beans is naturally better.

Maybe everyone doesn't mind if you have more soy milk and less soy milk. However, compared with non-soaked beans, the content of anti-nutritional factors in soybean milk will also be significantly different. It seems that people in China traditionally soak beans overnight before grinding soybean milk, which is quite scientific and beneficial for the body to make full use of the nutrients in soybean milk.

So, how should beans be soaked, how long should they be soaked, and at what temperature?

Soaking at room temperature of 20-25℃ 12 hour can make soybeans fully absorb water, but prolonging the soaking time will not get better results.

2. However, when the temperature is high in summer, soaking 12 hours at room temperature may lead to the problem of bacterial growth, which will make the flavor of soybean milk worse.

So it is recommended to soak the beans in the refrigerator. Soak beans in the refrigerator at 4℃ 12 hours, which is equivalent to soaking beans at room temperature for 8 hours. If 18 hour operation is too troublesome, you can soak the beans in the refrigerator for 24 hours, which can get the best effect and is very convenient to operate.
