Definitions
- the present invention relates to a process for the preparation of a mixture of a structured fat phase and some water, and to the use of such in the manufacture of a spreadable edible emulsion comprising fat and a structuring agent, in particular to such mixtures comprising fat and a structuring agent as continuous phase and a dispersed phase.
- the dispersed phase may be an aqueous liquid (thus forming a water- in-oil emulsion).
- the present invention relates to the use of the mixture of the structured oil phase with some water so prepared as a semi-finished product which may be stored for some time and/or to be transported.
- Edible emulsions comprising oil and a structuring agent are well known.
- examples of such products that substantially consist of such edible dispersions are water-in-oil emulsions, such as for instance margarines and spreads.
- Such products typically have a fat phase comprising a liquid (at 20 °C) oil phase and a solid (at 20 °C) fat phase. This solid fat is often also designated as hardstock, and if processed correctly can provide structure to the oil and stabilization of the dispersion.
- EP 1 651338 and other patent publications describe the manufacture of micronised fat particles that can be used to structure a fat phase for dispersions.
- EP 1 651338 also describes how such structured fat phase can be used to make a spreadable edible dispersion comprising a dispersed aqueous phase.
- Such process usually comprises the steps of:
- micronised fat particles with said oil phase to form a structured oil phase
- EP 1 865786 discloses a process for manufacturing a spreadable emulsion in which the aqueous phase is added gradually to the structured oil phase. Gradually adding is defined as in two or more different portions at different times during the process (if conducted batchwise) or in two or more places in the process equipment in a continuous process. In the above process, it was found, the mixing in of the aqueous phase with the structured oil phase should occur not too long after formation of the structured oil phase. This is an issue to take into account, as the various steps are carried out batch- wise, and the micronised particles themselves are very bulky and difficult to handle, hence the earlier it is blended with the oil phase the more convenient.
- EP 2367439 discloses a process for the preparation of an edible fat continuous food product. The process involves preparing a fat mixture comprising a fat powder and liquid oil, followed by mixing with the aqueous phase followed by filling in tubs. The exemplified product, once finalized, is stored for one week before being analysed on quality and spreadability.
- WO 2010/069753 discloses a process for the preparation of a fat-continuous spread, the fat phase comprising a fat powder.
- GB 1252264 discloses a process for manufacturing a spread comprising 70-90% fat.
- step 9 processing such into a spreadable edible emulsion.
- the amount of aqueous phase which is added in step d. is from 3 to 15%, preferably from 5 to 12% by weight on the total slurry weight.
- the above describes a process for manufacturing products like e.g. spreads.
- the fat phase produced by step c. is preferably carried out such that a structured oil phase is obtained, such as e.g. known in the prior art cited.
- Such products can be finished products.
- the present invention can also be used to manufacture a semi-finished products, in that a structured oil phase is manufactured, which is sufficiently stable to be stored for some time or even to be transported.
- Storage can be advantageous when the line has to be closed down for failure, cleaning, or other reason.
- Being able to transport the structured oil phase can be advantageous e.g. when manufacturing the micronised fat powder occurs in one location, whereas the manufacturing into a final product (involving the mixing with substantial amounts of water and optionally other components occurs in a different location. Structured oil phases so far produced could not be stored or transported for considerable time for reasons stated, whereas the current invention does allow such.
- the present invention further relates to a process for the preparation of an edible mixture comprising at least 85% of fat and 1 to 15% of an aqueous phase, both weight % based on the total weight of the mixture, the fat comprising 3-25% of a micronised fat powder and 75-97% of a fat not in powdered form, both weight % on the total fat phase, the process comprising the steps of:
- the fat phase containing the oil and the micronised fat particles is preferably processes such that it is a structured oil phase. Such processing is known in the art.
- Micronised fat powder is herein to be understood as a particulate matter comprising at least 80% by weight of fat, which particulate matter is solid at 20 °C, which micronised fat powder is obtainable by a super critical melt micronisation process, as described in J. of Supercritical Fluids 43 (2007) 181 -190 and EP 1651338.
- Fat is herein to be understood as one or more lipids, at least 80% by weight composed of fatty acid triglycerides. Preferably said fat comprises at least 80% by weight of vegetable fat. Fat herein includes oil.
- Fat not in powdered form is herein to be understood as Fat, but other than in powdered form (including other than micronised fat powder).
- fat not in powdered form is fat liquid at 20 °C (i.e. commonly understood as an oil).
- the two processes as set out above are the same, except that the first process contains two additional steps, in that a second amount of a water phase is added, and the product is processed into an emulsion, preferably such as a spread.
- the second water phase in step f) may be of the same as the first (in step d) or of a different aqueous composition. Either of such has its own
- the micronised fat powder utilized herein has a composition such that it is solid at 20 °C. It is furthermore preferred that such micronised fat powder is manufactured by a process involving super critical melt micronisation process, and more preferably such as described in J. of
- the amount of micronised fat powder used in the processes according to the present invention such is not different from processes as known in the art that structure oil with micronised fat powder.
- the amount of the micronised fat powder on the total fat phase is preferably from 5 to 20%, and more preferably from 7 to 15% by weight on the fat phase.
- the slurry is a structured fat.
- Such storing in step e. is preferably from 18 hours to 3 days, and more preferably from 24 hours to 2 days.
- the temperature of the mixture containing a slurry of fat and micronised fat powder (e.g. a structured oil phase) and which now contains some water is preferably stored in the processes according to the present invention at a temperature below the melting point of that of the micronised fat particles. More preferably, such is at a temperature of from 0 to 20 °C, even more preferably from 4 to 10 °C.
- the dispersion that is stored is preferably kept in motion. Such can be carried out by conventional means, e.g. high speed impellers and/or anchor-stirrers.
- the fat not in powdered form is fat liquid at 20 °C.
- Such is commonly understood as to be an oil.
- Preferred fats herein are vegetable fat.
- the fat not in powdered form it is preferred that such is liquid at 20 °C, e.g. an oil.
- the fat not in powdered form is a vegetable fat, e.g. a vegetable oil.
- the fat preferably comprises (more preferably for at least 50% of the fat) sunflower oil, rape seed oil, corn oil, palm kernel oil, coconut oil.
- the water phase was acidified to pH of 4.8 using 20% citric acid solution.
- inES48 is an interesterified mixture of 65% dry fractionated palm oil stearin with an Iodine Value of 14 and 35% palm kernel oil.
- a micronised fat powder of inES48 was used that was obtained using a supercritical melt micronisation process, as described in J. of Supercritical Fluids 43 (2007) 181 -190 and EP1651338.

- the maximum temperature increase observed due to mixing was about 21 .5 degrees Celsius. Before being fed into the C-unit see below the temperature of the oil-slurry was about 20 degrees Celsius.
- the so-obtained slurry (fat phase) was transported to the fat run tank.
- the water phase was prepared by dissolving the sodium chloride in the water and adjusting the pH to about 4.8 using 20 wt. % citric acid solution. Before being fed into the C-unit, see below, the water-phase was cooled to about 1 2-1 3 degrees Celsius.
- the remainder of the fat slurry was divided into 3 portions. Demi water was added to two of the three portions of fat slurry and mixed in to form mixtures which contain 5% (158gr water in 2998gr fat/water mixture, example 3) and 10% demi water (401 gr water in 3612gr fat/water mixture, example 4).
