If the deoxidizer changes color/consistency, stops suppressing odors or protecting the product from spoilage, it will lose its effectiveness - these are the main characteristics.
Appearance changes: Deoxidizers will change color (such as turning black, yellow, or uneven) or consistency (if initially dry, they will compact, open, or become wet).
Odorless: Stop suppressing unpleasant odors (fish, fish, mold) in the packaging - this means it no longer binds to these substances.
Product deterioration: Products protected by deoxidizers deteriorate before their shelf life (turning black, showing mold, changing taste) - deoxidizers cannot function properly.
Weight change (some types): Iron based deoxidizers may increase weight when reacting with oxygen - if there is no or little change in weight, the efficiency is low.
Oxygen test: Use an oxygen indicator - if it shows the presence of oxygen in the packaging, the deoxidizer will fail.
Packaging information: Check the shelf life and storage conditions of the deoxidizer - if they are damaged, efficiency may decrease.
