Quick Answer
Oxygen absorbers can be used with most foods in Mylar bags, but it's essential to follow specific guidelines and precautions to ensure food safety and effectiveness. They are not suitable for all foods, particularly those rich in moisture or fat.
Choosing the Right Oxygen Absorbers
When selecting oxygen absorbers for Mylar bags, it’s crucial to consider the type and quantity of food being stored. For example, for dry goods like rice, beans, or pasta, a general rule of thumb is to use 1-2% oxygen absorbers by weight, which translates to 1-2 grams of oxygen absorbers for every 100 grams of food. For high-moisture foods like meats or cheeses, it’s best to use a higher concentration of oxygen absorbers, around 5-10% by weight.
Precautions and Considerations
Before sealing Mylar bags with oxygen absorbers, make sure to follow proper food preparation and packaging techniques to prevent cross-contamination and spoilage. This includes cleaning and drying the food, selecting the right Mylar bag size, and properly sealing the bag with a heat sealer or tape. Additionally, it’s essential to store the Mylar bags in a cool, dry place, away from direct sunlight and moisture. Failure to follow these guidelines can lead to ineffective oxygen absorption, spoilage, or even foodborne illness.
