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.
Cool and store in a sealed container at room temperature. It should keep for up to two months. Alternatively, add granulated or brown sugar to a recipe that calls for corn syrup, cup for cup, then increase the amount of liquids used in the recipe by 1/4 of the amount of sugar added. Honey is one of the best substitutions for corn syrup because it is also hygroscopic.
