What are oxygen absorbers?

If you ever brought a beef jerky or mexico pancakes, you must be wondering what is the sachets inside the package is. This small white packet most likely to be Oxygen Absorber, which is the best efficient tools to keep food in a safe phase. Oxidization is always the problem within food packaging industry, and mildew is the absolute posion to most food, people are trying so hard to solve anti-mildew many years, and since oxygen absorber was invented about 40 years ago, this problem has been long forgetten.

Oxygen is the third most abundant element in the universe, and it is essential to all enciroment inside our earth atmosphere. Since oxygen is alomost everywhere not only in living organic life but also non-organic earth elements, it is the source of human life, however, it also can reduce the longevity of food, pharmaceutical, metal, and many human inventions, that are shown on the chemistry periodic table.

One solutions to prevent oxidization from food, pharmaceutical, metals are using oxygen absorbers. Oxygen absorber was invented as acidity formulas, it changed to alkline at 1989 by Mr.GX Ying, who is the founder of our company Tianhua Tech. Now, Oxygen Absorber are compressed by iron powder, which has a chemistry reaction with H2O, CO, and many different materials to produce heat and kills oxygen. Oxygen absorber do not release harmful gases or toxic elements, thus pass FDA,SGS,and all pharmaceutical\drug\food commisions tests.

Tianhua(Both Oxyfree® and Medshield®) distributes a production line that making oxygen absorbers called (Oxyfree® and Medshield®). which are the cure for many food and pharma products. They will elliminate almost 3 times their weight of oxygen, which will reduce the breed of mildew microbe. That is normally the job of additives, gas flushing and vacuum packaging. In additional, Oxyfree® and Medshield® can protect products from mold or discoloration.

Oxyfree® are safe and will be effective for:

1. Western cake product

2. Chinese cake product

3. rice, grain, pasta, seeds, pet food, nuts.

4. Dried fruit&vegetables (Gas swapping techniques)

5. Spices, seasonings

6. Coffee, Tea, Cocoa

7. Processed&Dried meat

8. Art preservations&metal products

Medshield® are safe and will be effective for:

1. Solid dose medications

2. Liquid dose medications&liquid infusion bags&three chamber bags

3. Vitamin medications&anti-biotics medications

4. anti-humor medications&kidney cancer medications

5. pharmaceutical machines including photics gentel care

6. Parenteral nutritions&Any oil Nutritions

Typical applications：

Food preservation

As food prices continue to climb, many people are searching for ways to make their money go further, and bulk purchasing has become a popular solution. Whether preparing for the colder months or simply aiming to cut everyday expenses, storing food in advance has turned into a common practice.

A crucial factor in keeping food fresh over long periods is removing oxygen from its packaging. Oxygen absorbers offer an ideal answer to this challenge — when placed inside sealed bags, jars, or containers, they quickly capture any residual oxygen present.

During storage, it’s essential to maintain flavor, shelf life, and nutritional value. Whether your goal is long-term preservation or added protection during shipping and retail, oxygen absorbers effectively stop bacteria, mold, and fungi from spreading. They are safe, non-toxic, and approved for direct contact with food, making them a trusted option for secure food storage.

Pharmaceutical preservation

With increasing attention on the safety and stability of medicines, proper storage has become a critical concern for pharmaceutical companies and healthcare providers. Extending the shelf life of drugs and ensuring their effectiveness requires strict control over storage conditions.

One of the most important factors is the elimination of oxygen inside the packaging. Oxygen absorbers provide a reliable solution, as they can be easily placed into sealed pouches, bottles, or containers to remove residual oxygen.

By protecting pharmaceuticals from oxygen exposure, these absorbers help preserve the chemical stability, potency, and intended therapeutic effects of medicines. They also reduce the risk of oxidation, microbial contamination, and degradation. Non-toxic and safe to use in direct contact with packaging, oxygen absorbers are an essential tool for ensuring that pharmaceutical products remain safe and effective throughout storage, shipping, and distribution.
