Choosing the Right Oxygen Absorber: Applications and Key Considerations
At NINGBO INNO PHARMCHEM CO.,LTD., we understand that selecting the correct oxygen absorber is critical for achieving optimal product preservation. These small packets are far more than just desiccants; they are active components that significantly contribute to maintaining product integrity. This guide will help you navigate the choices and understand the applications of oxygen absorbers.
The primary function of an oxygen absorber is to scavenge oxygen from sealed packaging. This is achieved through a chemical reaction, typically involving iron powder. When exposed to the internal atmosphere of a sealed package, the iron powder reacts with oxygen, converting it into iron oxide. This process drastically lowers the oxygen levels within the package, creating an environment that inhibits the growth of aerobic bacteria and mold, and prevents oxidation reactions that degrade food quality, flavor, and appearance. This is why they are an essential part of food preservation technology.
When considering buying oxygen absorbers for snacks, dried fruits, or nuts, it's important to match the absorber's capacity (measured in cc) to the volume of the package. A common recommendation is to use an absorber that can absorb at least twice the volume of oxygen present in the package. For instance, a 100cc oxygen absorber is suitable for a package of around 3-4 liters, assuming it contains approximately 21% oxygen.
The benefits of food grade oxygen absorbers are particularly important in the food industry. They help maintain the original color, aroma, and taste of food products, which are often compromised by oxidation. This leads to a better consumer experience and extends the perceived freshness of the product, directly supporting shelf-life extension techniques. Furthermore, by preventing the growth of mold and bacteria, they contribute significantly to overall food safety.
Beyond food, oxygen absorbers find critical applications in other sectors. In the pharmaceutical industry, they protect sensitive drugs and vitamins from oxidation, ensuring their potency and stability throughout their shelf life. They are also used in the packaging of textiles to prevent mildew and in the preservation of optical instruments. The goal is always to extend food shelf life with oxygen absorbers and protect other sensitive items.
While iron-based absorbers are prevalent, it’s worth noting the existence of non-iron based absorbers. These are used in specific scenarios, such as when products pass through metal detectors and any iron content could trigger a false positive. However, for most food applications, the efficiency and cost-effectiveness of iron-type oxygen absorbers make them the preferred choice.
At NINGBO INNO PHARMCHEM CO.,LTD., we provide a range of oxygen absorbers to meet diverse needs. Understanding your product and packaging volume is key to making the best selection. By utilizing the right oxygen absorber, you can ensure superior product quality and longevity.
