It is sometimes convenient to categorize packages by layer or function: primary, secondary, etc. 1  Primary packaging is the material that first envelops the product and holds it. 2  Secondary packaging is outside the primary packaging, and may be used to prevent pilferage or to group primary packages together.
Does Corn Need To Be Refrigerated? Corn does not typically need to be refrigerated in order for it to be safe to eat. You will want to be aware of the fact that the longer you keep your corn in the refrigerator, the more flavor and vitamins you will lose, so it will not have quite as much nutritional value or taste to it.
Tami,You should refrigerate leftover boil peanuts just as you would cooked peas or beans. There is so much moisture in boiled peanuts that they will spoil and may harbor bacteria if left out at room temperature more than a couple of hours. Boiled peanuts taste great cold, and the refrigerator will keep them fresh for several days (again like leftover peas or beans). For longer term storage you can freeze boiled peanuts. Just put them in a plastic bag, and place them in the freezer. Frozen boiled peanuts will stay good for many months.
