Put it in a light-shielding container, fill it with nitrogen, seal it, and store it in a cool place.
β-carotene avoids oxidation during application. Because β-carotene has many double-built structures, it is easily isomerized under the action of heat, ions and light, and is easily oxidized when exposed to oxygen. In addition to oxygen, light, heat and other factors, antioxidants, metal ions, pH, etc., also have an impact on the stability of β-carotene. Therefore, when β-carotene is used, it should be isolated from oxygen, light, high temperature, etc., and embedding technology should be used to solve this problem.
In addition, the oxidative degradation process of β-carotene is often associated with the decolorization process. The oxidative degradation includes photodegradation and thermal degradation, and the degradation process is often accompanied by isomerization between the cis and trans forms. In response to this problem, substances with stronger antioxidant properties can be added during use to protect β-carotene.
