| titleOfInvention | Distalliative process of extracting and purifying phytosterols and phytostanols from tall oil pitch |
| abstract | A process for isolating and purifying phytosterols and phytostanols from tall oil pitch is disclosed which comprises the following steps: (a) feeding the pitch into a first distillation column; (b) distilling the pitch to remove excess rosin acids and fatty acids to form a distilled pitch; (c) saponifying the distilled pitch with an aqueous solution of one or more alkali metal bases to form a saponified pitch; (d) neutralizing the saponified pitch with an amount of acid sufficient to achieve an ending pH of between 5.8 and 6.3 thereby forming a neutralized pitch; (e) allowing the neutralized pitch to phase separate for a period of at least 12 hours or until the water content of the pitch, on phase separation, is less than 15%, thereby forming a settled pitch and a water phase; (f) removing substantially all of the remaining water from the settled pitch to form a modified pitch; (g) distilling the modified pitch in a second distillation column to remove lights ends from the modified pitch and to produce a bottom fraction comprising free phytosterols and/or phytostanols; (h) distilling only the bottom fraction in a third distillation column to produce a light phase distillate comprising free phytosterols and/or phytostanols; (i) dissolving only the light phase distillate in a solvent comprising at least one alcohol to produce a solution of phytosterols and/or phytostanols; (j) cooling the solution to form a slurry with phytosterols and/or phytostanols crystallized therein; and (k) washing, filtering and drying the slurry to isolate the crystallized phytosterols and/or phytostanols from the filtrate. |
