摘要:
A method for preserving cooking oil comprises contacting the oil with oil- permeable cementitious material in the form of either stand-alone blocks, pellets, granules, or balls and which has been hydraulically hardened from a paste comprising (a) > 50 wt% of (i) white OPC clinker, (ii) white OPC or (iii) a mixture of white OPC clinker and white OPC, and (b) optionally further ingredients selected from silica, titama, lime, calcium sulphate, hydrated alumina, natural feldspars, diatomaceous earth, Na and Ca forms of natural and synthetic zeolites, clays, pillared clays, activated clays/earths, silicate minerals selected from calcium silicate, magnesium silicate, aluminium silicate, agalmatolite, amphiboles, attapulgite, granite porphyry, kaolinite, porphyry, rhyolite, talc and wollastonite, wherein the porosity of the cementious material is 30-55%. The treatment of the cooking oil takes place in a location separate from the frying chamber.
摘要:
An oil comprising (i) at least 30 wt.% of one or more polyunsaturated fatty acids having at least 4 double bonds; (ii) at least one first antioxidant; and (iii) less than about 1000 ppm lecithin. The oil may comprise less than about 750 ppm of a second antioxidant chosen from an ascorbic acid derivative.
摘要:
A fat-containing processed food composition is described that is suitable for human consumption, and that contains exogenously added microparticles of phenolic antioxidants dispersed but not dissolved in an antioxidant-protective edible oil/fat portion of the food composition. The oxidative stability of the phenolic antioxidants in the fat or oil portion of the food composition is substantially greater than when dissolved in an equal portion of water at pH 7.
摘要:
The present invention refers to a method for the preservation of olive oil which consists of freezing and/or vacuum-packing the paste obtained from ground olives. Additionally, the invention also comprises the olive paste obtained through the preservation method and the procedure for obtaining the olive oil and the olive oil obtained through this method.
摘要:
A method for modifying ethylenic unsaturation in a triglyceride. One or more unsaturated fatty acyl moieties present in the triglyceride are substituted with a lactone or ketone moiety via a electron donor mediated reaction. The resulting reaction products are useful, for example, as formulations for lubricants, hydraulic fluids, dielectric fluids, and intermediates for polymer synthesis.
摘要:
Compositions and methods to reduce the oxidation of an oxidizable material are disclosed herein. A composition comprising a phospholipid-stabilized oxidizable material is disclosed. The composition comprises an oxidizable material, a phospholipid, and an optional protein. The phospholipid reduces the oxidation of the oxidizable material in the absence of water.
摘要:
The present invention includes a solid fat composition that includes an oil having saturated fat and a microbial oil having a long chain polyunsaturated fatty acid and an emulsifier. In particular, the solid fat composition can have high levels of long chain polyunsaturated fatty acid and low amounts of emulsifiers. In preferred embodiments, the polyunsaturated oil is an unwinterized microbial oil. The invention also relates to methods for making such compositions and food, nutritional, and pharmaceutical products comprising said compositions. The present invention also includes a microbial oil product prepared by extracting an oil-containing fraction comprising at least one LC-PUFA from a microbial biomass, and treating the fraction by a process of vacuum evaporation, wherein the oil product has not been subject to one or more of a solvent winterization step, a caustic refining process, a chill filtration process, or a bleaching process.
