Storage Bean sprouts should be stored at 32°F (0°C) with a relative humidity of ninety-five to a hundred percent and with no mist. The typical shelf is five to ten days. High humidity is important to avoid dehydration and dried-out bean sprouts. High temperatures lead to a rotting and slimy appearance.

Bean sprouts produce a low level of ethylene. Bean sprouts are not sensitive to chilling injury and should be stored as cold as possible without freezing.
