Ginger oleoresin is characterized by pungency that is attributed to gingerol. It is very frequently adulterated with capsicum and grains of paradise, both of which are added to give increased pungency. Turmeric is also usually added to restore the colour. Ginger Oleoresin is obtained by the solvent extraction of ground-dried rhizomes of Zingiber officinale Roscoe. The product has the characteristic refreshing aroma of ginger. When evaluated in dilution, it has a pungent,biting sensation. It is a free-flowing, homogeneous, dark brown liquid.
