Salted Peanut

Salted peanuts are cotyledons or Hypogea sp either singly or in pairs, which have been roasted in order to break down the cell structure and allow the peanut oil to spread throughout the nut.
Even after roasting, remnants of the cell structure are still persistent. Within the cell (arrows) small oil droplets and other organelles can be seen.
Low temperature SEM is an idea method of investigating cotyledons either as a botanical material or in their treated form as a foodstuff. Application of conventional techniques results in considerable extraction of a variety of components, not least of which is lipid.
