Abstract: An orally administrable immunostimulant product comprises a microencapsulated cytokine and an enteric protection polymer to protect the cytokine, the cytokine is a fish, mollusc or crustacean cytokine, preferably a recombinant cytokine such as tumor necrosis factor ? (TNF?) over-expressed in a host microorganism.

Abstract: Hydroxytyrosol extracted from olives and/or from the solid residues of olives after the extraction of olive oil, by acid hydrolysis and purification on resin columns eluted with water contains hydroxytyrosol and tyrosol, is free from sugars, has a residual content of Benzo[a]pyrene that is less than 2 microg/Kg (weight BaP/weight of extract as dry matter), containing a weight ratio of hydroxytyrosol to hydroxymethylfurfural of between 45:1 and 10000:1, and the content of hydroxytyrosol in the extract is at least 0.5% (w/w) with purity of at least 40% (by HPLC 280 nm).

Abstract: Hydroxytyrosol is extracted from olives and/or from the solid residues of olives after the extraction of olive oil, by carrying out acid hydrolysis at a temperature within the range of 110° C. to 140° C. and at a pH within the range of 1.0 to 6.0, and by purifying the obtained solution on a column containing acid activated anion exchange resins, and a column containing an adsorbent non-ionic resin; both columns being eluted with water to recover the hydroxytyrosol.
