Tyrosol : A Key Polyphenol In Morocco Gold Extra Virgin Olive Oil
Tyrosol is a phenylethanoid, a derivative of phenethyl alcohol. It is a natural phenolic antioxidant present in a variety of natural sources. The principal source for human diet is in high quality extra virgin olive oil like Morocco Gold. As an antioxidant, tyrosol can protect cells against injury due to oxidation.
Along with hydroxytyrosol, tyrosol is one of the most abundant polyphenols in extra virgin olive oil, where they occur as such, or in the form of esters of elenolic acid. There is an increasing level of research into these polyphenols and their properties to determine which is the most significant contributor towards the range of health benefits associated with high quality extra virgin olive oil.
Tyrosol is a colourless solid at room temperature, melting at 91–92°C and slightly soluble in water. Hydroxytyrosol on the other hand appears as a clear colourless liquid at room temperature. It is now believed that this affects the rate of ‘uptake’ when ingested with hydoxytyrosol acting more quickly in the gut, however tyrosol accumululating intercellularly over time to provide longer term protection due to its higher concentration and good bioavailability.
Health Benefits Of Tyrosol
Its beneficial properties for human health are strongly related to the ability of the molecule to scavenge free radicals and reactive oxygen/nitrogen species as well as to activate endogenous antioxidant systems in the body. Free radical scavenging properties have been convincingly confirmed in studies on rats with alloxan-induced diabetes mellitus.
