Deacidification of fats and oils
The invention relates to method for deacidification of fats and oils comprising: feeding stream (1) to a stripping section; condensing the volatile phase in a high temperature condensing zone, sending the condensed phase to distillation A; distillating the condensed phase, obtaining a volatile stream; passing the volatile stream along with the vapor phase from the condensation zone to a cold condensation zone obtaining a condensate and a stream (4); allowing stream (4) to continue to vacuum system and subjecting the cold condensate to distillation B; and producing a stream of fatty acids (5) and a stream of micronutrients (6).
PREPARATION OF STEARIC ACID
One or more techniques are disclosed for a process of preparing stearic acid from animal and/or plant sources may comprise: 1) deodorizing and distilling a fat; 2) concentrating fatty acids of the fat; and 3) hydrogenating the fatty acid to provide stearic acid. The process may include the use of co-products from plant and/or animal sources. The process may also include distilling the stearic acid to provide palmitic acid and/or fully hydrogenated fatty acid. Tallow fatty acid, vegetable fatty acid, stearic acid, and palmitic acid prepared from the process described are also disclosed.

Composition containing highly unsaturated fatty acid or alkyl ester thereof and a method for producing the same
PROBLEM To provide a composition comprising highly enriched PUFA or its alkyl esters while containing fatty acid esters of 3-MCPD at adequately low concentrations and to provide an efficient method for producing the composition. MEANS FOR SOLVING A composition that contains fatty acids or fatty acid alkyl esters as its major component, the composition containing highly unsaturated fatty acid or alkyl ester thereof, wherein the proportion of the highly unsaturated fatty acid in the constituent fatty acids of the composition is 50 area % or more and wherein the concentration of 3-MCPD as found upon analyzing the composition by American Oil Chemists' Society official method Cd 29b-13 assay A is less than 1.80 ppm.

Enrichment of triterpine esters
A new process for enriching triterpene esters comprising: providing a mixture comprising a non-distilled vegetable oil and/or a non-distilled vegetable fat, further comprising triterpene esters, performing a mild transesterification with a lower alcohol, removing lower alcohol esters by deodorization, physical refining, evaporation or distillation, and recovering the remaining fraction rich in triterpene esters. Triterpene esters enriched with the method as well as uses of the same are also provided. One advantage is that it is a more economically viable way of achieving higher concentration of triterpene esters. There is both the chance to fully keep the natural distribution of triterpene esters but in the other end also to replace the natural level of cinnamic and acetic acids-triterpene esters with a high level of long fatty acid triterpene-esters.

Removal of unwanted propanol components
The present invention relates to the use of short-path evaporation for reducing from deodorized triglyceride oils the content of propanol components selected from chloropropanols, chloropropanol fatty acid esters, epoxypropanols, epoxypropanol fatty acid esters, and combinations of two or more thereof. It further relates to the use of short-path evaporation wherein further the content of acyl glycerol components is reduced and these acyl glycerol components are selected from diacyl-glycerols, triglycerides with molecular weight in the range below 730 and mixtures of two or more thereof.

PREVENTION OF MCPDE FORMATION IN TRIACYLGLYCERIDE OILS
A method is provided for preventing or reducing the formation of monochloropropanediols (MCPDs) or monochloropropanediol esters (MCPDEs) in triacylglyceride oil, comprising the steps: (a) concentrating insoluble components in liquid triacylglyceride oil by (i) applying a 5 centrifugational force on the triacylglyceride oil whilst maintaining the triacylglyceride oil above its melting temperature; and/or (ii) allowing the insoluble components to settle by gravitational force whilst maintaining the triacylglyceride oil above its melting temperature; (b) separating the triacylglyceride oil from the insoluble components; (c) optionally applying additional refining steps and (d) applying heat treatment to the triacylglyceride oil. A purified 10 triacylglyceride oil obtainable by the method of the invention is also provided.
