Product Name: OSA-Hydroxytyrosol
Synonyms: Octenyl succinic anhydride-Hydroxytyrosol,
IUPAC Name: (E)-3-((3,4-dihydroxyphenethoxy)carbonyl)undec-4-enoic acid,
Description: Hydroxytyrosol (HT) is a polyphenol mainly present in extra virgin olive oil (EVOO) that has a potent antioxidant activity. Moreover, HT provides other beneficial benefits that may be of importance for human health, namely anti-inflammatory and anticancer effects, enhancement of endothelial and vascular function, anti-steatotic properties, and improvement of endoplasmic reticulum stress, autophagy and mitochondrial function. Interestingly, HT is the only polyphenol recognized by the European Food Safety Authority as a protector of low density lipoproteins (LDL) from oxidative damage, considering the finding that HT reduces the expression of adhesion molecules in endothelial cells, preventing the oxidation of LDL. Starches modified with octenyl succinic anhydride (OSA) have been used in a range of industrial applications, particularly as a food additive, for more than half a century. Interest in these products has grown in recent years as a result of new methods and applications becoming available. Due to a combination of OSA’s hydrophobic and steric contribution and starch’s peculiar highly branched macromolecular structure, these starch derivatives display useful stabilizing, encapsulating, interfacial, thermal, nutritional and rheological properties.
