In soil, most of the zinc stays bound to the solid particles. When high levels of zinc are present in soils, such as at a hazardous waste site, the metal can seep into the groundwater. Industries also can release dust containing higher levels of zinc into the air we breathe.
Add sorghum to a large pot of water. Use one cup of whole grain sorghum to three cups of water. Bring to a boil, reduce to a simmer and let cook for approximately 40-55 minutes or until the sorghum is tender. Drain any remaining liquid and serve.
Oven Toasting. Oven toasting is another easy method for toasting grain. Barley, for example, can be lightly toasted in the oven before it is added to soups and other dishes. To toast barley, simply spread the barley grains evenly on a baking sheet and toast for about 10 minutes in a 350ÂºF oven.
