Vacuum Packaging - Why Its Used

You have heard about vacuum packaging all your life and every time you shop at you local grocery store you encounter it. What is the reason behind it and is it necessary, or is it just a gimmick? Also, what types of products does it benefit the most?

Does Vacuum Packaging Suck?

Dried Fruit

The basic principles behind vacuum packaging are quite simple. Heated plastic is encased around a product, or substance and before it has cooled and solidified, the air is sucked out of the package or container. The result, is that when the package cools, it is form fit around what it contains and most, if not all of the air in the package has been sucked out.

Gases Out - Product In

The air that you breath is actually a combination of several different gases, with oxygen being the most prevalent. Each type of gas has the potential to react with a variety of substances, with oxygen possible being the most reactive. For instance, an item that is made from steel will rust if it is expose to the air. By vacuum packaging a steel product, it is prevented from rusting while it is on a store shelf.

So many Products - So Much Packaging

The same goes for food products. Dried fruit for instance, will be effected by the oxygen and nitrogen that is in the atmosphere. By vacuum packaging dried fruit, its freshness and shelf life is extended greatly. On an on the list goes of products that benefit by being protected from the air that surround us and vacuum packaging is the most common method of protecting these products.

Food safety is another thing that vacuum packaging provides for consumers. When you pick up a package of hot dogs and can see that the vacuum seal is intact and viable, you can rest assured it is safe for your family. Should the vacuum packed hot dogs be bloated with gas, you then can plainly see that there is an obvious problem.

How to Interpret Packaging Dates on Food

Dates on food are written in many different ways and can be hard for the average consumer to make sense of. Interestingly, only a few of those dates tell you about the safety of consuming food past the stamped on date.

All processed factory-packaged foods are dated. Unfortunately, most of the time the date is in a code that is of no help to the consumer. These dates are used by the manufacturer and grocery store manager in a product recall and is required of all items packaged in the same place, on the same date.

The federal government requires product dating only on poultry, infant formula and some baby foods. Depending on your state regulations, some perishable foods have to have an "open date" that consumers can understand when choosing a product to be sure its fresh. For many other foods, dates are put on products voluntarily by manufacturers to ensure consumers get a "fresh" product.

If you know what those dates mean, you can know whether or not you want to purchase an item and also how long you have to use it. Here are some of the common terms and what they mean:

Packed on - This means the date the food was placed in package. If you are looking at fruit, this date will not tell when the fruit was picked, only the day it was placed in the package. So, this only helpful if you know how long that food stays fresh.

Sell by - This is the last date on which a store should sell a product to you. Another term for this is "pull date." You can usually find a "sell by" date on bread and bread products, dairy products, cold cuts and fresh fruit juices. Bakery products are commonly sold a day or so after their sell by date but for a lower price. Most foods that have gone past their "sell by" dates you can still use safely.

Milk - can be used for about a week after the "sell by" date.

Raw fish, meat and poultry - If you are not going to use by the "sell by" date you can freeze it.

Fruit juices, coffee, tea, nuts, dried fruit and fresh cranberries - If you are not going to use by the "sell by" date you can freeze them. I make it a practice of keeping my coffee, tea and nuts in the freezer to ensure optimum freshness.

Best if used by (Use by) - By this date, you should use the product if you want maximum taste. You may still consume the product after this date, it just might not have as much flavor.

Expiration date (Exp) - Expiration dates usually appear on yeast and baby formula and sometimes on milk. After the expiration date, most foods should not be used. Apparently, eggs are the exception. Eggs that are federally graded must have expiration dates not later than 30 days from the time they are put in the carton. Stores can't sells the eggs after this date, but you can use the eggs safely for the next month or so assuming you refrigerate your eggs properly.

High acid canned foods (ex. tomatoes) should be used within !8 months of purchase. You risk the chance of them exploding when you open them if you keep them too long.

Low acid canned foods - Fish, meat, most vegetable and fruits will keep in the pantry for two to five years.
