VacMaster Vacuum Sealers Buying Guide and Frequently Asked Questions
What is vacuum packaging?
The process of removing air around a food product and then sealing the product in an impermeable package.
Why vacuum package?
To extend the shelf life of any fresh perishable product by three to five times its normal refrigerated life.
How is shelf life extended under vacuum?
Removing the air that surrounds food inhibits growth of bacteria, mold, and
yeast because these and other spoilage microorganisms need oxygen to grow. Once
most air is removed and the pouch is sealed, oxygen levels continue to drop
while carbon dioxide levels increase. The low oxygen, high carbon dioxide
environment significantly reduces the growth of normal spoilage organisms,
allowing longer shelf life.
Yes. Some organisms are resistant to high carbon dioxide levels. Their growth is slowed at lower temperatures.
Who should vacuum package?
Anyone who buys, sells, transports, or stores perishable food products.
What are some special advantages of Vacuum Packaging?
WARNING – If vacuum packaged food is not: top quality; fresh; prepared in a sanitary manner; at proper pH levels; and, stored at an appropriate temperature, it may not reach optimum shelf life and could be harmful to a person’s health if consumed. Vacuum packaging is not a substitute for canning. Perishable foods must be refrigerated.
Typical Shelf Lives of Vacuum Packaged Products
Some typical shelf lives of vacuum packaged refrigerated products, as compared to normal refrigeration, are:
(Typical Shrink Loss: ½ to 1 ½% without vacuum packaging.) *(32º - 35º)
Vacuuming products will not automatically insure against spoilage. Good, clean packaging practices must be employed. Remember, a bad or contaminated product does not improve with vacuum packaging. The general rule is, if you put a fresh, good product in the pouch, you’ll get good fresh product our! Therefore, it is particularly important to:
Clean and sanitize surfaces that may come in contact with food products
Wash your hands
Wash personal gear, work spaces and utensils
Vacuum packaging equipment also needs careful attention. It is recommended that it be cleaned and sanitized at the end of each day.
Handling of Filled and Sealed Bags
VacMaster pouches are made of the finest virgin materials in a thickness suitable for handling, shipping and storing with only minimal care. Damage to packaged products may be avoided by adhering to these simple principles:
Avoid contact with carton staples or material handling devices that have sharp edges.
Use cartons that will not crush when stacked.
Wear gloves when handling packages. Rings and fingernails may cause scars that will eventually result in tears or pinholes.
Assure product being vacuum packaged is free of any sharp edges or points that may puncture the pouch.
Treat the pouch gently to avoid any breakage.
If breakage occurs, re-package immediately.
