Function comparison of SanDry® and General Commercial Oxygen Absorber | ||
---|---|---|
High-efficient deoxidization of SanDry® | General commercial deoxidizers | |
Raw Material | The cost of first-grade reduced iron powder is 1.5 timeshigher than that of cast powder. Iron rich and lowimpurity content contribute a stable quality ofSanDry®. Using a patented technique, the oxygenabsorption capacity per iron powder can be controlledwithin 290-295 ml which is the highest value in theory.(1) | The low-cost cast powder with its high level ofimpurity and a low content of iron make itunstable in quality. Depending on varioustechnique applied by manufacturers, theabsorption capacity per gram iron powder maybe controlled within a range of 100-200ml. |
Packing Time | The packing time can be controlled within a period of 0-12 hours with an exactness of 15 min/1 unit byapplying a patented manufacturing process. Thecurrent packing time is fixed at 2 hours. | The reasons why general commercialdeoxidizers fail to increase the packing time are: 1. Higher level of impurity contents 2. The chemical reaction time of the deoxidization can not be controlled because lacking of water-carrying material. The low oxygen absorption efficiency and uncontrollable freshness quality tend to affect the Q.C. requirements set forth by manufacturers. |
Package Material | A four-layered poly film The first layer: front side -- PET(polished) Back side—using food-printing ink The second and fourth layers: PE The third layer: high class candy paper( food category, neutral in chemical property, and no content of fluorscein) |
First layer: using cheaper PET or OPP The second and fourth layers: using PE The third layer: using cheap paper material as substitute (generally acid or basic in its chemical property and mostly contains fluorscein) |
Safety and Applicability | Non-toxic, no smell, a slightly moistened grain-shapedmaterial, causing no food contamination, a combinationof special patented ingredients, oxygen absorptionreaction is independent of the original moisture of thefood thus preserve the fresh flavor of the food. | Powdered deoxidizer, possible food contamination from leaking, some deoxidizers depends on the food moisture during oxygen absorption reaction thus affects the water activity and its original flavor of food. |
Certification | 1. National patent right approved by China Patent Bureau. ZL01130160.0 2. Certified by China National Accreditation Committee of Laboratory. 3. Deoxidization examination report issued by Taiwan Industry Technology Institute 4. Material safety examination report issued by Taiwan Food Industrial Research and Development Institute. 5. The product packing and content, non-metallic materials and non-toxic examination performed by SGS, an international certificate organization, all are complying with the regulations of Department of Health of Taiwan, FDA U.S. Food and Drug Administration, and EEC European Economic Community. |
General commercial deoxidizers are not certificated by any organization. Some products labeled as FDA certificated are actually not been approved by FDA. According to FDA, they have never issued approval to any deoxidizer. |
