Rice Safety Inspection

Rice is often polished with mineral oil to look shiny or treated with Urea to increase shelf life and prevent pest infestation. 1. The "Rub" and Shine Check: Rub a handful of rice grains vigorously between your palms. If they leave a greasy, translucent residue on your hands that doesn't wash off with plain water, they have been polished with mineral oil. Pure rice should be dry and leave a slightly white starchy powder. 2. The Water Float Test: Drop a spoonful of rice into a glass of water. Pure rice grains are dense and will sink. Adulterants like "plastic rice" (rare but possible) or heavily treated hollow grains will float or stay suspended. 3. The Smell Test (Urea): Take a deep sniff of the rice bag. Pure rice has a mild, earthy, or floral aroma. If you detect a faint "ammonia" or sharp chemical smell, it has likely been treated with Urea. 4. The Burning Test: Burn a few grains of rice. Pure rice should turn into black charcoal and smell like burnt starch. If it melts, produces a plastic-like smell, or leaves behind a hard, glassy residue, it contains industrial fillers or synthetic components.
