Price and classification of antioxidants

What does antioxidant mean? Antioxidant refers to the ability to resist the destruction and corrosion of active oxygen substances, which generally exists in terrestrial plants. Marine plants hardly need oxygen, so they have no antioxidant genes. For example, corals at the bottom of the sea will turn into stones when they leave the ocean, because they cannot resist the oxidation of land. People study the antioxidant effect of terrestrial plants and develop antioxidants. So how are antioxidants classified?

First, the price of antioxidants.

The price of antioxidants is divided according to classification. If it is an antioxidant used in industry and chemical industry, the price is generally not expensive, and it may be only tens of dollars per catty. But if it is an antioxidant suitable for human body, the price is more expensive. The general price is above 100 yuan. Antioxidants used in human body mainly refer to some natural oral capsules that scavenge free radicals, such as grape seeds.

Second, the classification of antioxidants

1, the food antioxidant should be

Antioxidants can be classified according to their sources, including synthetic antioxidants and natural antioxidants. Synthetic antioxidants generally refer to tea polyphenols and phytic acid, which are generally used as food additives or industrial rubber. Antioxidants can also be classified according to solubility, which is different from oil solubility and water solubility, and can also be classified according to compatibility. There are three types. Common oil-soluble antioxidants are BHA and BHT. Water-soluble antioxidants generally refer to antioxidants that can contain ascorbic acid and tea polyphenols. Compatible antioxidants are ascorbic acid and palmitate. The last category can be divided into: free radical absorber, oxygen scavenger, metal ion chelating agent, peroxide decomposer, ultraviolet absorber, enzyme antioxidant and singlet oxygen quencher.

2. Natural antioxidants

There are also many natural antioxidants. For example, tea is a natural antioxidant. Tea contains caffeine and tea polyphenols, which effectively eliminates free radicals. There are also some fruits that are natural antioxidants, such as apples and strawberries, which all contain strong antioxidants.

The above is the price and classification of antioxidants. Antioxidants can prevent metal oxidation and corrosion. Antioxidants are generally used in industrial and chemical industries, mainly for making rubber products. Antioxidants can effectively prevent the oxidation of substances and are widely used. I believe many people know that most living things depend on oxygen, which can not only sustain life but also produce free radicals to destroy living things, so the existence of oxidants is very important.
