Zingiberi corallinum oil's functions

The characteristics of zingiberi corallinum oil

Zingiberi corallinum oil is extracted with supercritical CO2 to obtain Zingiberi corallinum oil, The differences in antioxidant mechanism between coral ginger oil, BHT and VE on fish oil were discussed from the chemical composition. The results showed that the antioxidant effect of coral ginger oil was better than that of BHT and VE, and it was a good natural antioxidant. When the addition amount of coral ginger oil was 0.03%, it had a good protective effect on fish oil; GC-MS method identified coral ginger oil. There are 44 components: 13 monoterpenoids, accounting for 25.12%; 16 oxygenated monoterpenoids, accounting for 26.43%; 9 sesquiterpenoids, accounting for 8.82%; oxygenated sesquiterpenes, benzene series Derivatives and 6 others, accounting for 39.63%.

Zingiberi corallinum oil is a good antioxidant

Fats and oils are essential substances for human health. Various oils and fats not only bring deliciousness, energy and nutrition to human beings, but also provide certain preventive medical care effects. Concentrated fish oil is a high value-added oil rich in highly unsaturated fatty acids EPA and DHA.

It has good biological activity. It has been widely developed as medicine and health food, and added as a food additive to various foods including infant food. In addition to DHA and EPA biologically active ingredients, concentrated fish oil also contains natural pro-oxidant ingredients, such as heme, iron ions, etc.

During the storage or heating process of fish oil, under the action of oxygen in the air, light and enzymes, under the catalysis of pro-oxidants, unsaturated fatty acids are easily oxidized into hydroperoxides, and then decomposed into aldehydes, ketones and lower fatty acids, making the crude oil The quality decline has affected the reputation and health care effect of high-purity fish oil to a certain extent.

In addition to the unpleasant taste of oil products after oxidation, the generated organic peroxide free radicals and other small molecules will have adverse effects on human health. Adding antioxidants is an effective method to delay the oxidation of oils. Traditional antioxidants mainly include tocopherol (VE), artificial antioxidants dibutylhydroxytoluene (BHT) and butylated hydroxyanisole (BHA), etc., but synthetic antioxidants such as The safety issues of BHA and BHT are increasingly suspected, and their use has been gradually restricted.

VE is less toxic and is considered to be a relatively safe antioxidant, but its antioxidant properties are not as good as BHA and BHT, and to a certain extent, it also limits Antioxidants are a hot research topic at present, especially in high value-added pharmaceutical products and food, more tend to add natural extracts with both antioxidant and other effective biological activities. With increasing attention, it has become an inevitable trend to develop natural antioxidants from spices and Chinese herbal medicines.
