What are oxygen absorbers and why are they used in long-term storage?
Oxygen Absorbers are used to remove oxygen from within a sealed environment, creating a nitrogen environment for long-term food storage. They protect dry foods from insect damage and help preserve product quality. They are used when dry foods are packaged in sealed containers. When used with proper packaging and sealing, the oxygen in the packaging is greatly reduced. Our absorbers bring the oxygen level down reliably to 01% or less.
What are the benefits of using them?
Extends shelf life
Prevents growth of aerobic pathogens and spoilage organisms, including molds
Eliminates the need for additives such as BHA, BHT, sulfur dioxide, sorbates, benzoates, etc.
Is oxygen really bad?
Oxygen, it's something that we cannot live without. Without oxygen, we wouldn't be able to breath, function and basically live. It is a necessity that all life must have, but there are in our lives that we can do without oxygen. Oxygen is known to cause food spoilage through oxidation or it supports other organisms that ruin our food by being one of its basic necessities of life too.
Oxidation is why iron rusts, newspaper yellows, and silver tarnishes. It also causes many nasty changes to food products that change flavor, texture, appearance and nutritional value.
How long does it take for the oxygen absorbers to work?
Oxygen Absorbers become warm to the touch when they are working. They take about 4 hours to achieve their rated maximum absorption.
