Soymilk can't be drunk after one day. The results of the experiment show that freshly squeezed soybean milk placed at room temperature, half an hour after the colony number of 210cfu/ml, 2 hours after the 255cfu/ml, 4 hours after the growth rate accelerated to 6 hours after the spike to 2070cfu/ml.

Compared with the room temperature, the refrigerated freshly squeezed soybean milk nourished the number of colonies is obviously less. The number of colonies in the soymilk after 6 hours of refrigeration was the same as that in the soymilk left at room temperature for 1 hour.

Zhu Yi, an associate professor at the School of Food Science and Nutritional Engineering at China Agricultural University, pointed out that if freshly squeezed soymilk is left open at room temperature, bacteria in the air will enter the soymilk and grow as it slowly cools.

She suggests that if you make freshly squeezed soy milk in summer, it's best to drink it now. If you're afraid of scalding, you can quickly cool the soymilk in a quick-cooling container or keep it sealed in the refrigerator after it's cooled to prevent it from spoiling.
