What is ISO 23942 about?
ISO 23942 specifies a method for the quantitative determination of hydroxytyrosol and tyrosol content in extra virgin olive oils using reverse-phase high-performance liquid chromatography (RP-HPLC) with spectrophotometric detection. The method is also applicable to all other olive oils of a different commercial category.
Who is ISO 23942 for?
ISO 23942 on the determination of hydroxytyrosol and tyrosol content in extra virgin olive oils using RP-HPLC is beneficial for
- Microbiologist
- Biotechnologists
- Food technologists
Why should you use ISO 23942?
Biophenolic compounds of a secoiridoid nature and type of extra virgin olive oil (Olea europaea L.), are derived from oleuropein and ligstroside and are correlated to different beneficial health effects for human beings other than particular sensorial characteristics. The biophenolic compounds contain, in an esterified form, two aromatic alcohols, namely hydroxytyrosol and tyrosol. The method given in ISO 23942 is based on an extraction of the biophenolic fraction with a methanol/water solution and a subsequent hydrolysis reaction to produce free tyrosol and hydroxytyrosol.
ISO 23942 provides information on reverse-phase high-performance liquid chromatography (RP-HPLC) with spectrophotometric detection which helps users to determine and extract hydroxytyrosol and tyrosol content from olive oils which have several beneficial uses for human health.
