Oxygen absorbers for dehydrated food do not harm the fruits and vegetables and don't lead to toxication. A major benefit is that it eliminates the use of vacuum packaging and nitrogen flushing, as our OxySorb removes 99.9% oxygen from the product and keeps them fresh for a longer period. They are not reusable, however, can be partially used. It is important to store the rest of the content of the sachet in an air-tight container for future usage.
