Abstract (en)

[origin: WO9845390A1] The invention provides a wax composition which can be used in comestibles. The wax composition is obtained from sugar cane and comrpises wax esters, aldehydes, tri-glycerides, alcohols, free fatty acids, sterols and polar lipids. A process for preparing a wax composition from crude sugar cane wax, the process comprising the steps of: (i) heating a solution of the crude wax with a lower alcohol as sovlent at the boiling point of the solvent; (ii) allowing phase separation of the solution from (i) and decanting the upper phase while hot; (iii) allowing the separated phase from (ii) to cool and separating crystallised wax from the solvent; (iv) repeating steps (i) to (iii) using the wax from (iii) until all pitch has been removed fromthe wax; (v) heating the wax to between 90 and 140 DEG C and oxidising molten wax with oxidising material; and (vi) continuing the heating under and inert gas on completion of the oxidation step until intermediate peroxide products are removed.
