Article in English: One major effect of rinsing is the removal of starch that clings to the outside of the rice grains. If left unrinsed, the starch can cause rice grains to stick together, creating clumps or a glutinous texture. When you're making steamed rice, rinse it first to remove the starch and make clump-free, fluffy rice. If you're making a creamy dish like risotto, or a sticky dish like rice pudding, however, you need the starch to achieve the right texture. Thorough rinsing will remove that starch and leave you with a watery dish.  Short-grain rice is the most likely to stick together, while long-grain rice like basmati tends to cook into dry, separated grains.  If you want to make risotto but the rice is dirty, rinse it, then add a couple spoonfuls of homemade rice flour to the recipe. This will return the starch to the dish. In the United States, most domestically grown rice has been washed before sale, and contains few contaminants. Rice grown in many other countries, however, may contain dirt, insects, pesticides, or small rocks. If you notice a powder on the surface of the grain, this may be talc or another substance added to improve appearance. This is edible, but your rice will cook better and taste better if you rinse it off. Contaminants may be more likely in bulk bags of rice. Enriched white rice has been thoroughly washed, then coated with a dust of vitamins and nutrients. Rinsing will remove a large portion of these beneficial ingredients.  This rice is typically low in dirt and other contaminants, but it does still contain surface starch. In the United States, some enriched rice labels include a warning not to rinse the rice for this reason. If U.S. enriched rice does not have this label, you can rinse it for one minute without major loss of nutrients. More than other crops, rice tends to pick up arsenic that naturally occurs in in water and soil. If rice is a major part of an infant's or pregnant woman's diet, this could affect the child's development. The US FDA recommends feeding babies and toddlers a...
