Abstract

A continuous process for refining oils or fats of vegetable or animal origin, for human consumption, comprises coagulating the proteins and mucilaginous substances contained therein with acids (e.g. HCl, H2SO4, H3PO4, acetic acid or citric acid), neutralizing the free fatty acids with an aqueous alkali hydroxide or carbonate solution in the presence of th coagulated proteins and mucilaginous substances, removing water from the mixture by reduced pressure treatment, and treating the mixture with a solution of a salt (e.g. NaCl, KCl, Na2SO4, K2SO4) until the soaps formed by the neutralization are converted into flowable oil-repellent hydrophilic flakes, and then separating the oil from the flakes and coagulated matter by centrifugation. The resulting oil is free from soap and can be immediately bleached and deodorized without first being washed. In examples, the process is used to refine soybean oil, rape oil and peanut oil.
