US 12,305,144 B2 · Oil processing systems and methods for manufacturing a refined vegetable oil

Abstract

A process for manufacturing a refined vegetable oil having a reduced content of 3-monochloropropane-1.2-diol fatty acid (3-MCPD) esters characterized in that it comprises the following steps: treating a deodorized vegetable oil with a base in a continuous pipe reactor, and contacting the base treated oil with an adsorbent and/or an acid. The thus obtained oil is low in 3-MCPD and has a low degree of interesterification and a low dialkylketones (DAK) content. It further relates to the use a continuous pipe reactor for treating a deodorized vegetable oil with a base wherein 3-MCPD ester content is reduced in the oil.

Dependent claims

A process for manufacturing a refined vegetable oil, the process comprising:

A) treating a deodorized vegetable oil with a base in a continuous pipe reactor to obtain a base treated oil, wherein the deodorized vegetable oil comprises 2.5 ppm or more of 3-monochloropropane-1,2-diol fatty acid (3-MCPD) ester, and wherein the continuous pipe reactor is arranged to provide a retention time having a standard deviation of 40% or less of a mean residence time within the continuous pipe reactor, and
B) contacting the base treated oil with an adsorbent, an acid, or a combination thereof, wherein the refined vegetable oil comprises below 2.5 ppm of the 3-MCPD ester.
