While mold on food, except for specific cheeses, is a clear indicator of spoilage—often appearing green or bluish-green, like on bread—green grains in brown rice aren’t a sign of fungus.
Before you throw away your rice, know this: Brands like Mahatma and Carolina explain on their FAQ pages that these green grains are simply immature rice kernels, offering the same nutritional benefits as fully matured ones. The green hue comes from chlorophyll, the same pigment responsible for the color of unripe bananas, unripe tomatoes, and most green plants.
According to PCC Community Markets in Seattle, these green grains are likely harvested from the lower parts of the rice stalk, which mature more slowly. Their presence is actually a good sign, indicating that the rice hasn’t been overly processed to achieve a uniform color.
If green grains aren’t a sign of spoiled brown rice, what should you look for? The usual indicators of spoilage apply: unpleasant smells, a slimy texture, bugs, or visible mold. To avoid mold, which thrives in moisture, store your rice in an airtight container in a dry place.
When it comes to the debate between brown rice and white rice, brown rice is generally healthier, though both have their unique strengths.
