If the soybean milk has not deteriorated and remains fresh, it can be reheated without producing harmful substances and causing harm to the human body. However, it is generally recommended to drink fresh soybean milk, which is not suitable for secondary heating, mainly because soybean milk loses more nutrients during secondary heating, among which calcium and protein lose the most, which will affect the taste.
The misunderstanding of drinking soybean milk
Anecdotal saying: Soymilk must be hot, and drinking cold soy milk will cause diarrhea.
Soymilk is made from soybeans. From the nutritional analysis, soybean contains some anti-nutritional factors, such as trypsin inhibitor, lipoxygenase and phytohemagglutinin. Drinking raw or uncooked soybean milk may cause gastrointestinal symptoms such as nausea, vomiting, abdominal pain, bloating and diarrhea, but these anti-nutritional factors can be eliminated by heating. Therefore, raw soybean milk must be boiled, so that these harmful substances can be completely destroyed before drinking. Therefore, it is not that cold soybean milk can't be drunk, but that raw soybean milk can't be drunk. Boiled soybean milk can be safely drunk when it is cold.
People's Network-Health Myth: Soymilk can be drunk cold. Don't believe those rumors.
