A method for obtaining an olive oil in situ, which comprises the operation of packaging and preserving a dry olive preparation formed from an olive paste that is firstly frozen and then freeze-dried in a capsule, preferably a single-dose capsule; and the operation of reconstituting the olive paste by hydrating it inside the capsule to obtain an olive oil that will be extracted from the capsule by pressure. The capsule comprises a filtering membrane having micro-perforations suitable for retaining the preparation and the passage of traces of olive wastewater or water particles therethrough, which may contain an olive oil obtainable from rehydrating the olive paste inside the receptacle and a machine for cooperating with the capsule comprising an injection head of a liquid and a piston prepared for pressing the preparation and subjecting it to a pressure greater than 10 bar.

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, titania, 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.

Provided is means of powderizing a liquid component, wherein the powderizing agent contains an oil and/or fat composition, the oil and/or fat composition contains an oil and/or fat component which contains one or more types of XXX-type triglycerides having fatty acid residues X, each with x carbon atoms, at positions 1 to 3 of glycerin, x, the number of carbon atoms, is an integer selected from 10 to 22, and the XXX-type triglyceride is contained at 50% by mass or more relative to a content of the oil and/or fat component being 100% by mass; or the powderizing agent, wherein the oil and/or fat composition is a powder oil and/or fat composition having a loose bulk density of 0.05 to 0.6 g/cm.sup.3, the oil and/or fat component contains a β-type oil and/or fat, and a particle of the powder oil and/or fat composition has a plate shape.

Disclosed are a microcapsule fat powder of Ω3-enriched meat, egg and milk and its preparation method, and the powder includes a water-soluble wall material and an Ω3 oil core material embedded in the wall material. The water-soluble wall material is prepared by mixing dextrin, water-soluble syrup, whey powder or chitosan with starch paste, and the Ω3 oil core material is prepared by mixing linseed oil, deep sea fish oil or algae oil with a composite emulsifier which is stearic acyl lactylate. The microcapsule fat powder can be combined with intestinal and pancreatic lipases very easily to improve the digestion, absorption and utilization of Ω3 oils.
