hydroxytyrosol skin-King of antioxidants
Hydroxytyrosol polyphenols is a natural polyphenol compound with strong antioxidant activity. It is mainly found in the fruits and branches of olives. Its molecular formula is C8H10O3. The molecular structure of hydroxytyrosol not only has a phenolic hydroxyl group like other phenolic substances but also has an alcoholic hydroxyl group on the ethanol chain with a benzene ring. Studies have shown that the antioxidant activity of hydroxytyrosol is closely related to its structure.
Hydroxytyrosol is the superstar of antioxidants As one of the strongest antioxidants in nature, hydroxytyrosol can remove free radicals that cause skin aging, protect cell membranes and mitochondrial membranes from oxidative damage, and reduce skin photoaging. Experiments by FocusHerb have proved that hydroxytyrosol can naturally enhance the body's natural sun protection mechanism and reduce skin damage and dryness caused by ultraviolet rays.
The human body is constantly exposed to free radicals from the living environment: strong ultraviolet radiation, industrial pollution, active or passive smoking hazards, radiation pollution, automobile exhaust pollution, etc. For example, when we breathe, we inhale contaminated free radicals, and our bodies will be attacked by free radicals. Free radicals can cause various diseases, such as cancer, leukemia, diabetes, liver disease, skin disease, etc. In addition, free radicals are also one of the culprits that accelerate the skin aging process. Of course, free radicals not only originate from the living environment but may also be produced in the metabolism after eating. Therefore, we must take measures to resist the damage of free radicals to the body. An antioxidant is the most important substance that resists free radicals. Olive fruit powder is rich in polyphenols and natural antioxidants, which can resist free radicals and effectively eliminate free radicals.
The natural miracle of olives in the Longnan Desert of Gansu,The production of polyphenols and hydroxytyrosol depends on the growth environment of the olive tree and the way it is extracted from olives. As we all know, olive trees are a bit like grapes, and the best fruits have to withstand harsh environments.
Olive trees are planted in a hot climate (the highest temperature in summer can reach 53°C). It is difficult for plant roots to grow on hard soil. Coupled with dryness and lack of water, the growth of olive trees usually faces great pressure (survival instinct). This survival instinct promotes the production of more polyphenols (self-protection through more antioxidants) in the interior, roots, and teeth of the olive tree. Therefore, in the olive trees grown in such an environment, a higher content of hydroxytyrosol, oleuropein, maslinic acid, oleanolic acid, flavonoids, and other polyphenols are extracted.
Comparison of hydroxytyrosol content and tyrosol content of different samples
According to the international test method recognized by the Folin Ciocalteu laboratory, the content of hydroxytyrosol in the traditional extra-virgin olive oil is 7mg/Kg. The content of tyrosol in extra-virgin olive oil is 30 times this ratio, which is 233mg/Kg
The total polyphenol content in extra-virgin olive oil is as high as 1250mg/kg (generally the total polyphenol ratio is 253mg/kg), which is nearly 5 times the general total polyphenol content.
For example, maslinic acid, oleanolic acid, hydroxytyrosol, oleuropein, the content standard of hydroxytyrosol is 20% HT, and the addition amount is 12.5%.
What is hydroxytyrosol good for?
Hydroxytyrosol is considered one of the most powerful antioxidants and has many health benefits. The pure ORAC value of hydroxytyrosol is 40 μmolTE/mg. The oxidation of low-density lipoproteins (LDLs) is a lipid peroxidation chain reaction, which is initiated by free radicals. It has been shown that hydroxytyrosol can inhibit LDL oxidation and is effective due to its ability to scavenge peroxy free radicals (Arouma et al., 1998; Turner et al., 2005). Hydroxytyrosol can reduce the oxidized cholesterol (LDL-C) carried by low-density lipoproteins, and is a key step to reduce the development of cardiovascular diseases such as atherosclerosis (Gonzalez-Santiago et al., 2010; Vázquez-Velasco et al., 2011).
Do olives contain hydroxytyrosol?
#FocusHerb has been working hard for many years to break through the mass production method of extracting hydroxytyrosol from the olive fruit, adopting the product crystallization process, the powder content can reach 40%, the advantages of the product are low ash, good fluidity, fully water-soluble, widely used, suitable for ordinary food and beverages, cosmetics, health care products. Olive fruit powder (hydroxytyrosol) can be used as a common food additive in China.100% pure natural;100% no solvent residue;100% water-soluble;USDA/EU organic certification; Halal & Kosher certification;
