The bubbles that sometimes form when rinsing sprouts are likely due to the release of carbon dioxide gas. Sprouts are living plants and, as they grow, they produce carbon dioxide as a byproduct of respiration. When the sprouts are rinsed, the agitation of the water can cause the carbon dioxide to be released from the sprouts and form bubbles on the surface.
The formation of bubbles during the rinsing of sprouts is not harmful and does not indicate any issue with the quality or safety of the sprouts. It is a normal process that can occur during the growth of sprouts.
In addition to the release of carbon dioxide, rinsing sprouts can also help to remove any dirt, debris, or bacteria that may be present on the surface of the sprouts. This is an important step in ensuring that the sprouts are clean and safe to eat.
It’s important to handle and store sprouts properly to reduce the risk of food borne illness. This includes washing the sprouts thoroughly before eating, keeping them refrigerated, and consuming them within a reasonable amount of time after they have been harvested or purchased.
