除氧剂系无毒材料制成的复合物,只与空气中的氧起反应。在密封容器中将它和物品放在一起,即可实现除氧封存,从而有效地防止物品霉变、虫蛀、腐蚀及氧化变质。如用于加工食品封存时,还可保持制作时的风味和色泽。这种应用除氧剂进行包装封存的新技术,由于使用简便、安全、易于商品化,并配有氧指示剂,随时可观察贮存是否有效,故在国外已颇为流行。除氧剂封存新技术的中药材保质试验结果表明:采用除氧剂及聚酯/聚乙烯复合薄 Oxygen scavengers are compounds made of non-toxic materials that react only with oxygen in the air. By placing it in the sealed container with the article, deoxygenation can be achieved, thereby effectively preventing moldy, insects, corrosion, and oxidative deterioration of the article. When used for processing foods, they can also maintain the flavor and color of the product. This kind of new technology using oxygen scavenger for packaging and storage is quite popular in foreign countries because it is easy to use, safe, easy to commercialize, and equipped with an oxygen indicator, so it can be observed whether the storage is effective at any time. The results of the durability testing of Chinese herbal medicines with new oxygen scavenger storage technology show that the use of oxygen scavenger and polyester/polyethylene composite thin
