Description

These oxygen absorbers in powdered milk are small packets containing a blend of safe, non-toxic materials designed to remove oxygen from sealed packaging. By reducing oxygen levels, these absorbers help preserve the freshness, flavor, and nutritional value of powdered milk while extending its shelf life. They work by chemically reacting with oxygen to create a stable environment, preventing spoilage caused by oxidation or microbial growth. Oxygen absorbers are widely used in the food industry to maintain product quality and are safe for direct use in food packaging.

Performance

Oxygen absorbers used in powdered milk packaging have varying oxygen absorption capacities based on the size of the absorber. For example, it is estimated that air comprises roughly 20% oxygen, and a void space of 100ml would contain around 20ml of oxygen. The absorbers are manufactured in different sizes, such as 50cc, 100cc, 300cc, or larger, with increasing capacities to match the volume of oxygen within a sealed container. For powdered milk, typical recommendations suggest 50–100cc oxygen absorbers for smaller packages and up to 1000cc for larger containers. These oxygen absorbers in powdered milk effectively reduce oxygen levels, prolonging the shelf life and maintaining the quality of powdered milk.

Safety

These absorbers are safe for preserving powdered milk, because they effectively remove oxygen from the packaging, preventing oxidation and spoilage without introducing harmful chemicals. Designed with food-grade materials, these oxygen absorbers in powdered milk create an ideal environment that extends the shelf life of powdered milk while maintaining its nutritional value and safety for consumption.

FAQ

Q1: Does milk powder need to be completely vacuum packed when it is stored?

No. You only need to use a well-sealed package. This oxygen absorber will actively remove the oxygen in the package. Even if it is not vacuum packed, it can produce a similar protective effect.

Q2: Will it affect the nutritional content of milk powder?

No. Its function is to reduce the impact of oxygen on milk powder and avoid nutrient loss. At the same time, it does not change the composition or quality of the milk powder itself.

Q3: If there is still a small amount of air in the package, will the oxygen absorber still work?

Yes. It is specially designed to absorb trace oxygen. Even if there is a small amount of air in the package, it can effectively remove the oxygen in it and keep the milk powder in the best storage condition.

Q4: Can these oxygen absorbers in powdered milk be reused?

No. This product cannot recover its function after absorbing oxygen. It is usually used once added to the packaging.
