On packages of enriched rice sold in supermarkets, the rice preparation directions state that the rice should not be washed before cooking. Explain.

The rice must not be washed due to the following reason:

Explanation:

The washing of rice is important for removing the dirt and contamination so that the food prepared through rice remains contamination free. But the washing process prior to the process of cooking removes the significant amount of vitamin B1 or thiamine. This vitamin allows the body to use carbohydrate as a source of energy and it is also necessary for the glucose metabolism.

Thus the food enriched with the rice preparation direction suggests that the rice must not be washed before cooking as it will loose the essential vitamin while washing.

the plates spread at mid-ocean ridges (they are divergent plate boundaries) which allows magma to rise through the weakness between the plates. the magma then emerges as lava from the boundary and cools, creating a new crust.
