Abstract:
Substantially pure stearidonic acid is isolated from a mixture of polyunsaturated fatty acids by fractionating at 25% to 35% by weight solution of fatty acids by high-performance reverse-phase liquid chromatography using a mobile phase of 75% to 95% by weight methanol and 25% to 5% by weight water. The isolated stearidonic acid is used to prepare pharmaceutical compositions which are administered to treat cardiovascular and thrombo-embolic diseases associated with platelet aggregation.
Abstract:
A mixture of fatty acids, including derivatives thereof, containing polyunsaturated fatty acids, including derivatives thereof, are reacted with urea in solution. The reaction medium is pumped through at least one scraped-surface heat exchanger for cooling the reaction medium for forming a dispersion of a solid inclusion complex and a liquid phase. The liquid phase which contains a fraction enriched with polyunsaturated fatty acids, including derivatives thereof, then is separated from the inclusion complex.

Abstract:
A crumb-flavored milk composition is prepared by incorporating free fatty acids selected from the group consisting of oleic acid, linoleic acid and .alpha.-linolenic acid, or by incorporating a lysolecithin lysate or a milk treated with a modified lipase which preferentially releases unsaturated long-chain fatty acids.
Abstract:
A native lipase from Mucor javanicus is modified by bonding it to a pectin. The pectin-modified lipase releases fatty acids of identical chain length from a lipidic substrate in a lower saturated-to-unsaturated fatty acid ratio than the native, unmodified, lipase.
Abstract:
Food compositions are prepared by incorporating in a food a diester or triester of fatty acids and an aliphatic C.sub.4-5 diol or triol having secondary alcohol functions. Fried foods may be prepared by frying the food in the presence of the diester or triester.
Abstract:
Fat substitutes are prepared without a molecular distillation step by enzymatically or chemically interesterifying a fully hydrogenated vegetable oil rich in stearic acid (FHLCT) with a medium chain fatty acid triglyceride rich in caproic, caprylic and capric fatty acids (MCT) under conditions such that the amount of tristearin in the interesterified mixture is lower than 5% by weight. The interesterified mixture is bleached and deodorized, and may be used as a substitute for butterfat or vegetable butter, e.g., cocoa butter.
Abstract:
Food compositions having an added .gamma.-linolenic acid component are provided for human and animal nutrition. The supplemented foods contain an oil extracted from pips of Ribes genus fruits containing at least 4% by weight of .gamma.-linolenic acid. The oil is substantially free from waxes, odorous compounds, colorings and free fatty acids.
Abstract:
The oil of pips of fruits of the Ribes genus is an abundant, cheap source of .gamma.-linolenic acid.It is extracted using solvents from dried and ground residues from the production of juices, preserves and jellies or brandies, liqueurs and schnapps of fruits, such as blackcurrant, redcurrant or gooseberry. According to a preferred embodiment, the residues are treated with ethanol before being extracted with hexane in order to free the oil from most of the free fatty acids, waxes, colorings and odorous compounds.The refined oil is a valuable ingredient in cosmetic, dermatological, dietetic and pharmaceutical compositions.
Abstract:
Improved process for the interesterification of a phospholipid with a triacyl glycerol is obtained by using an enzyme system containing immobilized lipase and immobilized phospholipase. The phospholipids obtained have better heat stabilized properties and better emulsifying properties than regular lecithin and may be used in emulsion systems or in coatings for instantized powders.
