Introduction
However, if glutinous rice is soaked at room temperature for two days—especially in the high temperatures of summer—it easily promotes the growth of molds, bacteria, and other microorganisms. If you notice the rice has become sticky, developed white or green mold spots, or emits a sour or alcoholic odor, it has spoiled. Consuming it may cause gastrointestinal discomfort such as abdominal pain and diarrhea, and in such cases, the rice should be discarded immediately.
Generally, glutinous rice that has been soaked for two days can be consumed if it has been properly refrigerated and shows no signs of spoilage. However, if soaked at room temperature or showing any abnormalities, it should be discarded. If in doubt, carefully check its condition before consumption. The detailed analysis is as follows:
If glutinous rice is promptly placed in the refrigerator during soaking, with the temperature maintained between 0–4°C, and the soaking water is changed at least once, bacterial growth can be effectively inhibited. In such cases, after two days of soaking, the rice grains remain plump, odorless, and non-sticky. After rinsing thoroughly, they are safe to cook and consume, with minimal impact on both nutritional value and texture.
However, if the glutinous rice has been soaked at room temperature—especially in hot summer conditions—it becomes highly susceptible to mold and bacterial contamination. If the rice appears sticky, develops white or green mold spots, or emits a sour or alcoholic smell, it has already spoiled. Consuming it may lead to gastrointestinal discomfort such as abdominal pain and diarrhea, and it should be discarded immediately.
When soaking glutinous rice, refrigeration is recommended, and the water should be changed at least once during the process. Ensure the rice is fully and thoroughly cooked before eating. If the soaked rice tastes sour—even without visible mold—it is still advisable to discard it.
