The present invention relates to method for deacidification of fats and oils comprising the following steps: step (i) feeding an oily feed stream (1) to a vacuum steam stripping section, stripping off a volatile phase; step (ii) feeding the stripped off volatile phase to a high temperature condensing zone, condensing the volatile phase from volatile phase and sending the condensed phase to distillation A and a vapour phase is sent to cold condensation zone; step (iii) subjecting the condensed phase to a vacuum distillation operation in distillation A obtaining a volatile stream rich in micronutrients and fatty acids ; step (iv) allowing the volatile stream along with the vapour phase from the high temperature condensation zone to pass to a cold condensation zone obtaining a condensate and a stream (4); step (v) allowing stream (4) to continue to vacuum system and subjecting the cold condensate from the cold condensation zone to distillation B; and step (vi) subjecting the cold condensate to distillation B producing a stream of fatty acids (5) and a stream of micronutrients (6), and a stream of volatiles (4), said volatiles are sent to vacuum system together stream (4) from cold condensation zone. |
