Zinc is a metal that is normally found in small amounts in nature. It is used in many commercial industries and can be released into the environment during mining and smelting (metal processing) activities. People living near smelters or industries using zinc could be exposed to higher levels of zinc by drinking water, breathing air and touching soil that contains the metal.
Step 3: Blanch the green beans. 1  Bring a large pot of water to boiling. Allow 1 gallon of water per pound of green beans. 2  Fill a large bowl with ice water. 3  Working in batches, carefully lower the green beans into the boiling water.  Boil small beans for 2 minutes, medium beans for 3 minutes, and large beans for 4 minutes.
Leave whole. Water blanch 11/2 minutes for small pods; 2 minutes for large pods. (NOTE: If the peas have started to develop, follow the directions for green beans. If the peas are already developed, shell and follow the directions for green peas.) Cool, drain and package, leaving 1/2-inch headspace. Seal and freeze.
