摘要:
The present invention has the objective to provide a stable gas-in-oil-in-water emulsion. Such emulsions can be used as food products, for example as a mayonnaise or salad dressing. This objective has been achieved by a gas-in-oil-in-water emulsion, which is prepared by combining a mixture of sucrose fatty acid ester in water, with an aerated oil containing sucrose fatty acid ester. The aerated oil is dispersed in the aqueous phase, to a product containing oil droplets containing gas bubbles in a continuous aqueous phase. A gas-in-oil-in-water emulsion has been developed which is stable against oil exudation, phase separation and phase inversion for at least two months.
摘要:
A method of production of a fat mix with a decreased fat content, consisting in cream separation from milk, fat content normalisation, pasteurisation, preparation of a cream mixture with milk powder and/or other protein carriers, pasteurisation of the mixture, refrigeration, homogenisation, addition of starters, souring, introduction of the other condensing and flavour additives, thermisation, smoothing homogenisation, hot packing is characterised by the fact that pasteurised, normalised cream, supplemented or not with an addition of recombined cream, is completed with milk protein carriers and the entire mixture is submitted to thermal processing in 85-135°C for 10-180 seconds, degassed, cooled down to 30-55°C, supplemented with transglutaminase in solution or solid form, in a quantity of 0.1- 20.0 U/g of the protein, then the entire product is kept in this temperature for 15-70 minutes, followed by thermal processing in 70-92°C for 30-180 seconds, cooled down to approximately 72°C, homogenised and treated in a standard way by an addition - or not - of taste and flavour components, submission to thermisation, formation, packing and refrigeration. Transglutaminase is added separately to the thermally processed cream and to the thermally processed solution of milk protein carriers or to the thermally processed solution of milk protein carriers. Milk protein carriers can be: skimmed milk powder, whey powder, milk, condensed by evaporation or by means of membrane systems (UF, RO, microfiltration), concentrate/isolate of milk proteins, concentrate/isolate of whey proteins or their mixture. Recombined cream is added in a form of prepared mixture of skimmed milk and vegetable oils and/or animal fats and/or modified fats.
摘要:
The invention relates to a process for the manufacture of an edible low-fat water-in-oil emulsion comprising an aqueous phase and at most 45 wt. % of a fat phase, wherein said fat phase comprises liquid oil and structuring fat, comprising the steps of: a. providing an aqueous phase comprising a gelling system; b. providing fat powder comprising structuring fat; c. forming the edible low-fat water-in-oil emulsion by mixing said aqueous phase, said fat powder and liquid oil; ⋅ wherein the aqueous phase comprising a gelling system at step c has a viscosity of at most 100 mPas at 5 degrees Celsius, ⋅ and wherein the liquid oil may be mixed at any of steps a, b or c, or when mixed in parts in any combination at steps a, b and c The invention further relates to an edible low-fat water-in-oil emulsion comprising ⋅ at most 45 wt. % of a fat phase, and ⋅ at most 25 wt. % saturated fatty acids, based on the total weight of the fat phase, and ⋅ a dispersed aqueous phase comprising a gelling system, wherein said aqueous phase has a viscosity of at most 100 mPas at 5 degrees Celsius, and wherein the dispersed aqueous phase is characterized by an D3,3 of at most 20 micrometer and an e^sigma of at most 2.0, more preferably of at most 1.9 and most preferably of at most 1.6.
