The invention relates to a process for recovering fatty acids, resin acids and sterols from tall oil pitch, said process comprising a) saponifying the tall oil pitch with an alkali to hydrolyse esters included in the pitch to free alcohols and organic acids in salt form, b) acidulating the saponified pitch with a mineral acid to convert the organic acids in salt form into free organic acids and to form an organic phase and an aqueous phase, c) separating the aqueous phase from the organic phase, d) evaporation fractionating the organic phase to obtain a distillate rich in sterols, fatty acids and resin acids, e) evaporation fractionating the distillate to obtain a bottom fraction rich in sterols, and a distillate rich in fatty acids and resin acids, and f) subjecting the sterols in the sterol-rich bottom fraction to crystallisation purification. The invention also relates to an alternative process including steps a) to c) followed by d1) treating the organic phase with an alkali to destroy excess mineral acid used for acidulating the saponified pitch, e1) evaporation fractionating the alkali-treated organic phase to obtain a distillate rich in fatty acids and resin acids and a bottom fraction rich in sterols, f1) evaporation fractionating the bottom fraction to obtain a distillate rich in sterols, and g1) subjecting the sterols in the sterol-rich distillate to crystallisation purification.
摘要:
A process of obtaining sterols suitable for human consumption from a crude wood pulping source containing sterol esters is disclosed. The sterols are obtained at high yield and purity. In particular, a process of obtaining sterols at high yield and purity from tall oil pitch (TOP) is disclosed. The sterols obtained can be esterified to sterol esters for use in dietary supplements and as additives for food and beverage products.
摘要:
The invention relates to the field of vegetable oil refining technologies, more particularly, to the technology of wax removal from vegetable oils by freezing out or winterization, and can be used for the improvement of the existing and the development of new technologies. Separated used filtering product regeneration step is added to the method of wax removal from vegetable oils the working cycle of which comprises winterization of the vegetable oil with the addition of auxiliary filtering powders, low temperature exposure of the oil and separation of the used filtering powder with the wax containing residue from the refined vegetable oil. To this end the used filtering powder is mixed with the additionally introduced fatty product to a paste condition, said paste is heated with stirring to the melting point of all the waxed and the resultant mixture is separated by centrifugation to obtain regenerated dry filtering powder and a wax containing fatty product. The regenerated filtering powder can be multiply recycled as the auxiliary filtering powder in the subsequent working cycles comprising winterization of the new vegetable oil portions wherein each working cycle is followed by regeneration of the used filtering powder.
