I. Introduction

Vitamin E (VE) is the general name for tocopherols, also known as vitamin E. It is a golden or light yellow oil with a mild special smell. Usually, vitamin E is easily oxidized and appears dark red when exposed to air when exposed to light. Vitamin E is one of the essential vitamins for the human body. It is widely present in the germ of green plant seeds, especially in soybeans. Natural vitamin E is usually extracted from the fatty acid distillate during soybean oil refining. At present, natural vitamin E extracts are divided into two categories: mixed tocopherol (low type) and tocopherol (high alpha type). It appears as a brown-red or transparent light yellow oily liquid with a mild, special smell and taste. Vitamin E has a high boiling point (200°C) and is very stable to heat. It has no heat of its own and does not participate in human metabolism.

 2. Storage method

Before understanding the correct storage method of vitamin E powder, we need to understand the basic characteristics of vitamin E powder. Vitamin E is relatively sensitive to light, heat and oxygen, and is prone to oxidation reactions under light or high temperatures, resulting in reduced activity or even complete failure. Therefore, the environment where vitamin E powder is stored should avoid direct sunlight, maintain low temperature and humidity, and try to avoid frequently opening closed containers.

Specifically, the main methods for storing natural vitamin E powder are as follows:

1. Avoid light: When considering how to store vitamin E, it is important to realize that light is a key factor in accelerating its degradation, especially ultraviolet radiation. Therefore, in order to ensure the stability of vitamin E, measures should be taken to keep it in a dark place. Specifically, using opaque or dark-colored containers for storage is an effective method, which can significantly block light, especially UV rays. Another option is to wrap the outside of the container where vitamin E is stored with a layer of light-shielding paper to further prevent any potential sunlight, thus keeping its ingredients intact. This careful storage strategy helps extend the shelf life of vitamin E and maintain its potency.

2. Low temperature: Natural vitamin E powder is very sensitive to temperature changes, so please make sure it is not placed in an overheated environment. The best practice is to choose a cool, dry place with good air circulation to store, while maintaining the temperature between 15°C and 25°C. In summer, special attention should be paid to avoid direct sunlight and high temperature baking, as these may reduce its quality.

3. Sealing: Oxygen in the air can cause vitamin E powder to oxidize. Therefore, vitamin E powder should be stored in a sealed container to reduce its chance of contact with air. You can choose containers with good sealing properties, such as glass bottles with rubber stoppers or aluminum-plastic composite film bags.

 3. Summary

From the above introduction, we can see that storing natural vitamin E powder is not difficult. As long as you follow the principles of avoiding light, low temperature, sealing, opening less, adding anti-caking agents, and paying attention to the expiration date, you can effectively store it. its activity and exert its due effect.

In different environments such as household and industrial production, we all need to develop appropriate storage strategies according to specific conditions to ensure that vitamin E powder can still maintain its excellent antioxidant capacity when needed, bringing long-lasting benefits to health care and skin care. benefit.
