The invention relates to a process for removing unwanted propanol components from unused triglyceride oil, said unwanted propanol components being selected from free chloropropanols, chloropropanol fatty acid esters, free epoxypropanols, epoxypropanol fatty acid esters, and combinations thereof, and said process comprising: ● contacting a triglyceride oil that is contaminated with unwanted propanol components with a silicate adsorbent selected from the group consisting of magnesium silicate, calcium silicate, aluminum silicate and combinations of these silicates; and ● recovering a decontaminated triglyceride oil having a reduced concentration of the unwanted propanol components. The invention further provides a deodorized triglyceride oil selected from palm oil, a palm oil fraction or a combination thereof, said deodorized triglyceride oil being characterized by a 3-MCPD content that is equivalent to less than 300 µg/kg of non-esterified 3-MCPD. In addition, the invention concerns an infant food comprising from 0.3-80 wt.% of the latter deodorized triglyceride oil.
摘要:
A process for separating polyunsaturated fatty acids (PUFAs) such as docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) from less saturated long chain fatty acids (LCFAs) in a lipid composition, wherein said PUFAs and LCFAs are present as (i) triglycerides, or (ii) free fatty acids or monoalkyl esters, by exchange of at least a portion of LCFAs with short and/or medium chain fatty acids (MCFAs). The process can suitably be employed on marine derived oil, marine oil 2 derived oil products and other sources of PUFAs, including PUFA-rich singe cell oils (SCOs), and oils from genetically modified organisms with a modified lipid metabolism. The inventive process is based on novel use of lipases and distillation techniques, selectively chemically modifying species in the substrate material such that the desired species and chemically similar species become sufficiently dissimilar to be separable. Thus PUFA can be effectively enriched from material such as 30 herring oil with low PUFA content and high content of equal length monounsaturated fatty acids such as 20:1 and 22:1 fatty acids.
摘要:
The present invention relates to a dry fractionation method for a reactant produced by the enzymatic transesterification of vegetable or animal oil and fat with a fatty acid derivative, wherein the method is characterized in that oil and fat having a high melting point are removed through dry fractionation when triglycerides and fatty acid derivatives are included in the reactant. The dry fractionation method according to the present invention performs dry fractionation without requiring a pretreatment process of separating a fatty acid derivative, which is used as the raw material for a transesterification reactant, from said reactant. Therefore, the fatty acid derivatives that remain during the reaction increase the fractionation precision of oil and fat, and serve as a solvent that reduces the viscosity of the oil and fat, thereby significantly improving fractionation yield

The present invention discloses a method of producing triglycerides rich in XOX fat and/or XLX fat, which comprises the steps of heating and dissolving triglycerides (XOX fat and/or XLX fat) which comprise 20 to 60 mass %of a triglyceride having a saturated fatty acid residue on each of the first and third position and an oleoyl group and/or a linoleoyl group on the second position in total triglycerides in the presence of 1 to 30 mass % of a fatty acid lower alkyl ester; and then cooling the mixture to precipitate crystals and conducting solid-liquid separation. This method is a more efficient and industrially suitable fractionation and production method of fats and oils which are rich in a triglyceride (XOX fat and/or XLX fat) having a saturated fatty acid residue on each of the first and third position and an oleoyl group and/or a linoleoyl group on the second position.

摘要:
Disclosed is an intermolecular compound of (a) a disaturated medium chain fatty acid monosaturated long chain fatty acid triglyceride and (b) a 1,3-disaturated long chain fatty acid 2-monounsaturated long chain fatty acid triglyceride, the intermolecular compound having a longer interplanar spacing as measured by X ray diffraction of 65 Å or longer. Also disclosed is a food comprising the intermolecular compound. The intermolecular compound can be used as a part of an oil/fat constituting a food. By forming an intermolecular compound of an oil/fat containing a large amount of a symmetric triglyceride (e.g., cocoa butter) and an oil/fat containing a medium chain fatty acid, it can be avoided to present these oils/fats in the form of separate crystals from each other. A product comprising the intermolecular compound can retain a smooth texture and has a reduced blooming.

Provided are palm oil of superior chromaticity and flavor and a manufacturing method therefor with which palm oil can be obtained with good yield even if a chemical refining method of alkaline deacidification is performed. Also provided are a palm oil manufacturing method with which deodorized distillates wherein useful components have been highly concentrated can be obtained, said deodorized distillates and a manufacturing method therefor. Refined palm oil and deodorized distillates as by-product are manufactured with a manufacturing process flow comprising a process wherein the palm starting material is steamed within 24 hours of harvesting and then pressed to obtain crude palm oil, a subsequent refining process wherein the crude palm oil undergoes alkaline deacidification to obtain the alkaline deacidified palm oil, and a deodorizing process.
