Abstract
Extraction and refining of vegetable cuticular waxes from aqueous dispersion using temperature and pH adjustment. This is a method for extracting and refining wax from plant material.In summary, the method comprises the steps of (a) providing plant material comprising cuticular wax, (b) dissociating the cuticular wax from the plant material by subjecting said plant material to a dry mechanical treatment and suspending the dry mechanically treated material, or a fraction thereof, in an aqueous solution comprising protease and / or pectinase enzymes, thereby obtaining a sample comprising plant-derived cuticular wax and plant material with wax removed in an aqueous suspension, (c) solubilizing the plant-derived cuticular wax by increasing the temperature of the sample, (d) separating the suspension into a solid fraction and a liquid fraction comprising melted plant-derived cuticular wax, (e) adjusting the pH and temperature of the liquid fraction to pH 5.5 or lower and 50 °C or lower, respectively, (f) separating the mixture into a waxy fraction and an aqueous fraction, (g) recovering the plant-derived cuticular wax from the waxy fraction.
