Why does bajra smell earthy after soaking?

Question

Wondering about the earthy smell of soaked bajra? Learn if this is a natural characteristic of the millet or a sign you should be concerned about.

Answer 1

Bajra smells earthy after soaking because soaking releases volatile organic compounds (VOCs) present in the grain, particularly geosmin, which is known for its earthy aroma. This is a natural characteristic of bajra.

Detailed Explanation:

Bajra, also known as pearl millet, is a grain that naturally contains various organic compounds. When bajra is soaked in water, these compounds, including geosmin and other VOCs, are released. Geosmin is produced by certain bacteria and fungi present in the soil where bajra is grown, and it adheres to the grain. Soaking facilitates the release of these compounds into the water, making the earthy smell more noticeable. The intensity of the smell can vary depending on the variety of bajra, the growing conditions, and the duration of soaking. This earthy smell is not an indication of spoilage but rather a characteristic aroma of the grain when hydrated.

Pro Tip:

To reduce the intensity of the earthy smell, rinse the bajra thoroughly under running water before and after soaking. This helps to remove some of the surface compounds contributing to the odor.
