Hydroxytyrosol, as an ingredient with anti-inflammatory, antibacterial and anti-cancer functions, is widely used in medicine, cosmetics, daily chemicals and other fields. As an important pharmaceutical and chemical raw material, hydroxytyrosol can be prepared by a variety of methods, including biological, chemical or physical methods.
Hydroxytyrosol can be extracted from olive oil residue and esterified by enzyme or acid. Hydroxytyrosol can also be prepared by reducing 3, 4-dihydroxyphenylacetic acid as a raw material. Tyrosol or phenylethanol as raw materials can be converted to hydroxytyrosol by biocatalytic or chemical treatment, but this method is limited by raw materials and reactions and is currently only used in laboratories. In addition, in order to obtain hydroxytyrosol, catechol and glyoxylic acid as raw materials, through the synthesis of hydroxytyrosol.
There are many ways to prepare hydroxytyrosol, but in the face of mass production, the production process must meet the requirements of environmental protection, economy and safety, so as to achieve long-term production and development.
