摘要:
It is intended to provide a dry fractionation method for fat whereby the performance for fractionating a fat into a high-melting fraction, a medium-melting fraction and a low-melting fraction can be improved to thereby preventing, in particular, the medium-melting fraction from worsening of the melting properties in the mouth and a decrease in the melting point with the passage of time and, in its turn, improving the melting properties in the mouth of a chocolate product which is produced by using the thus obtained hard butter for chocolates, etc. A method of fractionating a fat wherein a fraction (in particular, a medium-melting fraction) obtained by dry fractionation is efficiently separated from a high-melting fraction and a low-melting fraction mixed therewith. More specifically, a dry fractionation method which comprises heating a crystal fraction containing a large amount of 1,3-disaturated-2-unsaturated triglycerides to thereby melt the 1,3-disaturated-2-unsturated triglyceride components followed by solid/liquid separation of tri-saturated triglycerides as a crystal fraction, thereby achieving a favorable performance of fractionating 1,3-disaturated-2-unsaturated triglycerides and saturated triglycerides.

A method for producing edible quality refined fish oil comprising the steps of extracting press liquor from a cooked fish, wherein the press liquor consists primarily of fish oil and water inherent in the cooked fish. The fish oil is from the group of fish consisting of menhaden, other similar fish, and mixtures thereof. Enzymes present in the press liquor are deactivated by injecting an acidic solution into said press liquor. After the fish oil is removed from the press liquor, the fish oil is cold filtered to produce an olein fraction and a stearine fraction. The stearine fraction is separated from the olein fraction and fatty acids that remain in the olein fraction are removed. Then bleaching the fish oil by mixing amorphous silica and diatomaceous earth with the fish oil, under vacuum conditions, and deodorizing the fish oil under vacuum conditions with steam injection. Finally, preparing the fish oil for storage by mixing a chelating agent and antioxidants with fish oil. Also disclosed is a refined fish oil that is free of unsavory taste or smell, have an anisidine number of less than 6, and retain more than 98% of the omega-3 long chain fatty acids present in the natural unrefined fish oil.
摘要:
A Trans free hard structural fat suitable for the manufacture of low SAFA (Saturated Fatty Acid) poly/mono unsaturated margarine and spreads and fat blends for margarine/spreads. The structural fat is made from selectively fractionated non-hydrogenated high melting palm oil fraction which is interesterified with dry fractionated non hydrogenated palm kernel fraction with high yield ratios that can be economically and commercially used as structural fat for the aforesaid manufacture.

摘要:
Die vorliegende Erfindung betrifft ein Verfahren und eine Vorrichtung zur Trennung oder Reinigung von gelösten, geschmolzenen oder flüssigen Verbindungen oder Verbindungsgemischen mittels fraktionierter Schmelzkristallisation, bei welchem Verfahren eine zu reinigende Verbindung oder ein zu trennendes Verbindungsgemisch in einen Behälter (13) eingebracht und in Kontakt mit Wärmetauscherflächen (15) gebracht wird, die Wärmetauscherflächen (15) auf der einen Seite mittels eines Wärmetransfermediums von einer Temperatur, welche vorzugsweise höher ist als jene, bei welcher die gewünschte Verbindung kristallisiert, auf eine Endtemperatur, bei welcher die gewünschte Verbindung wenigstens teilweise kristallisiert, abgekühlt werden, sodass sich eine aus Kristallen bestehende Kristallschicht der gewünschten Verbindung auf der anderen Seite der Wärmetauscherflächen bildet, dann der nicht-kristallisierte Teil der Verbindung oder des Verbindungsgemisches abgelassen wird und die Kristallschicht geschmolzen und die Schmelze in wenigstens einer Fraktion gesammelt und gegebenfalls, falls der gewünschte Reinheitsgrad noch nicht erreicht ist, einem neuen Reinigungszyklus unterworfen wird. Zum Schwitzen der Kristallschicht wird wenigstens zeitweise ein Gasstrom eines gasförmigen Wärmetransfermediums über die Kristallschicht geleitet wird, wobei der Gasstrom vorgängig auf eine Temperatur erwärmt wird, welche höher als die Schmelztemperatur der Kristallschicht ist.
摘要:
A frying fat is provided that is suitable for frying food products that are to be consumed cold, which frying fat
∗ is substantially free of trans unsaturated fatty acid residues ∗ includes 0-6% S3 triglycerides wherein S indicates saturated fatty acid residues ∗ includes at least 20% S 2 O triglycerides wherein O indicates oleic acid residue ∗ has a N 25 - N 35 value of at least 25 The substantial absence of trans unsaturated fatty acid residues is nutritionally attractive. The frying fat can also be used in combination with conventional frying fat provided that the frying fat constitutes at least 50% of the mixture. The frying fat can be produced by means of a process involving interesterification followed by fractionation to obtain an olein and optionally blending 80-100% of the olein with 0-20% liquid oil.
摘要:
A process for producing a fat blend, usable as hardstock in margarine and W/O spreads, comprising interesterifying a fat mixture comprising 30-55 % liquid vegetable oil and 45-70 % of a fat having at least 80 % saturated fatty acids of a chain length of 16 C-atoms or more, and fractionating the interesterified product to obtain an olein fraction having a solid fat content of N10 = 54-85, N20 = 32-70, N30 = 4-30, N35 = ∫18. A fat blend obtainable by this process, a margarine fat containing such fatblends and a fatproduct, in particular a margarine or W/O spread containing this margarine fat, or this fatblend.
摘要:
An unsaturated or low saturated frying oil which imparts the beefy or tallow flavor to foods that is characteristic of animal fats is disclosed. This oil is made by a process of esterifying glycerine with the unsaturated fraction of animal fat and then deodorizing or refining the resultant triglyceride. The unsaturated fraction of the animal fat contains minor fatty acids which produce this flavor on heating. Usually less than 5 mg of cholesterol/100 g is in the oil.
摘要:
A method for refining and fractionation of palm oil is disclosed. In this method, palm oil or palm fractionated oil which has been treated by physical refining is treated with an adsorbent, followed by subjecting it to dry fractionation. An apparatus for refining and fractionation of palm oil comprising means for treating palm oil or palm fractionated oil with an adsorbent and dry fractionation means connected thereto is also disclosed.
