What is the correct water absorption time for rice?

When rice is soaked in water, it is generally said to be soaked in water for 30 minutes to 1 hour in summer and 1 to 2 hours in winter.

The water absorption of rice is greatly affected by the water temperature, and when soaked in water (30°C or below), it absorbs 20-30% of the weight of the rice.
Also, the higher the water temperature, the faster the time to reach the saturated state.

According to the table above, at a normal water temperature of 10 to 20°C, it will be saturated after about 2 hours of immersion.
In addition, immersion is required for at least 30 minutes, as water absorption of approximately 50% of the saturated state occurs in 30 minutes.

It is generally considered good to soak for about one hour in summer and about two hours in winter.
* If the soaking time is too long (more than 15 hours), it may become unpalatable.
In addition, it is better to avoid long-term immersion in water as bacteria may spring up.
