EY - - @ Process for the manufacture of an evaporated milk substitute
The present invention relates to a process for the manufacture of an evaporated milk substitute which can be used as a dairy coffee whitener, that is to say based on whole milk, in which the milk is partially substituted with whey and/or lactose and the lactic fat may be partially replaced with vegetable fat.
The use of whey is known in the manufacture of reconstituted dairy products. The advantage of using whey as a partial substitute for milk is essentially linked to its low price. However, the use of whey even as a partial replacement for milk is a delicate : operation. It is indeed difficult to offer the product heat stability and a good shelf life with whey proteins. Another problem which is difficult to solve is to preserve the organoleptic qualities of the fresh milk in such a product, that is to say attenuate and if possible avoid the presence of a cooked flavour oo . normally associated with the concentration . by
B evaporation. .
Patent Application EP-A-0,627,169 relates to a process "for packaging milk which ‘makes it possible to partially ol achieve these set objectives. In the context of this patent application, the product to be packaged may be in the form of a whole milk, partially skimmed milk,
Sa .~ 30 skimmed milk or whey. The process comprises one stage.
However, this method does not only have advantages. In particular, the packaging process does not make it BE - : possible to avoid sedimentation after packaging, in = particular when the product is sterilized. Furthermore, "
N ‘ 35 the cooked flavour is evident. oo
Patent Application EP-A-0,832,565 relates to a milk
Co substitute containing an appreciable quantity of whey proteins in which the storage properties are 40 satisfactory. The process of preparation is based on a
: ® | - 2 - sequential dissolution of the whey proteins, and then of milk with no evaporation stage as it is a recombination. It 1s not possible in this case to preserve the organoleptic qualities close to those 5 which characterize fresh milk.
The invention therefore relates to a process for the preparation of an evaporated milk substitute whose organoleptic qualities are similar to those of fresh milk, in which a liquid whey product is mixed with fresh whole milk and then the mixture is pasteurized, it is concentrated by evaporation, heated and then the concentrate is thermally treated, the thermally treated concentrate 1s homogenized, it is cooled, it is packaged and the packaged product is sterilized.
According to a variant of the process, applicable in particular to fresh whole milk, an additional : | homogenization of the concentrate is carried out before heating it and treating it thermally.
The product obtained contains a substantial portion of whey as a replacement for the milk in the composition of the milk substitute. This substitution allows a ©. 25 substantial reduction in the cost of the raw materials cL used. It also has the advantage that the substitute raw material is of a lactic origin. The whey can be partially substituted and preferably up to an amount of
TE approximately half with lactose. In the text which oo 30 follows, in the context of the present patent . application, the term "whey product” will comprise the concepts of whey and whey supplemented with lactose, it - a being possible for the whey to in fact be demineralized : to a greater or lesser degree.
Although the whey is present in large proportions in the milk substitute, and thus the whey proteins, the heat stability of the product is not reduced as a oo result, which is unexpected. "Thus, at high
§ ‘® : C3. h temperatures, the milk substitute substantially reacts like normal milk packaged by conventional processes from the point of view of the «color, taste and consistency.
Moreover, the milk substitute has no or few calcium ions capable of precipitating to form an undesirable . deposit. Indeed, the free calcium ions are either buffered with the sequestering agent which is at least partially dissociated, or are alternatively bound in the casein micelles. In order to promote the low presence of calcium ions in the milk substitute, it is in addition appropriate to use deionized or demineralized water in its composition.
The sequestering agent or stabilizing salt is preferably a phosphate or citrate, for example mono-, -di- or trisodium phosphate or mono-, di- or trisodium citrate or mixtures thereof. 20 .
To prepare the milk substitute, the following quantities by weight of raw materials are preferably used: about 10 to 12% of fresh whole milk solids, about } 5 to 9% of whey powder, about 7 to 10% of lactic or vegetable fat which may be any vegetable fat and is preferably selected from palm oil, coconut oil, maize oo | oo oil or a combination of the latter. Furthermore, there - is required preferably about 0.1 to 0.3% of lecithin, i. } about 0.02 to 0.03% of carrageenan, about 0.10 to 0.15% a 30 of sequestering agent for the dissolution and about 0 - to 0.15% of sequestering agent for the sterilization, and about 68 to 80% of deionized water or preferably demineralized water.
The advantage of this process is that it makes it © possible to guarantee the finished product a temperature stability comparable to that of milk in spite of the substantial presence of whey proteins.
B ® Ca
Before starting to dissolve the whey powder, it is necessary to prepare the aqueous dissolution medium. It : comprises, by weight, about 68 to 80% of water, about 0.01 to 0.03% of carrageenan and about 0.1 to 0.15% of "5 sequeestering agent. The sequestering agent and the carrageenan may be incorporated into the water at a temperature of 30 to 65°C, preferably at about 60 to 65°C in a first vessel in two ways: by recirculation of the water through a powder dispenser supplying the sequestering agent and the carrageenan, or. alternatively, by separate predissolution of the carrageenan and the sequestering agent in a small quantity of water before mixing them with all the water with moderate stirring in order to form the aqueous dissolution medium.
Two methods may be envisaged for incorporating the whey 7
Co powder into the aqueous solution present in the first vessel at 30 to 65°C, preferably at about 60 to 65°C.
The solution is recirculated through a powder dispenser
R with the whey. powder, or alternatively the powder is : ‘added directly to the solution and dissolved with vigorous stirring.
After the dissolution of the whey in the aqueous medium, it is necessary to allow the whey solution thus . obtained to stand for 10 min to 4 h, preferably for 10 to 45 min at a temperature of about 40 to 65°C. This or _— standing time is necessary to allow the rehydration of oo 30 the whey proteins. oo Once the rehydration of the proteins has occurred, the oo whey solution can be mixed with, the fresh whole or .
Lo ~ partially skimmed milk. Starting with fresh milk, the = cooked flavour generally associated with concentration . by evaporation is avoided. oo
Before proceeding to the remainder of the operations, the lactic solution. should be preheated, preferably to about” 60°C in order to be able to incorporate therein the fats, in particular the butter oil and/or the vegetable oils, in the presence of lecithin. The oils as well as the lecithin are mixed and preheated to about 60 to about 65°C. The fatty phase is then integrated into the lactic solution and mixed, preferably with the aid of a static mixer or of a colloid mill. To ensure equilibration of the solution, = _ it is ‘allowed to stand. The standing period is preferably about 25 to 35 min if the operation is carried out in a vessel or 15 to 20 min if the milk is mixed on-line.
Following these operations, pasteurization of the : 15 solution, which can take two forms, is carried out. An indirect pasteurization for about 1 to 60 s, at about 80 to 85°C, may be carried out for example by means of a tubular or plate exchanger.
After the pasteurization, the solution is concentrated :
I by evaporation in a falling film and multiple-effect evaporator to a dry matter content of about 28% by weight. The concentrate is cooled in the evaporator to about 35-40°C. : ‘The concentrate is then preheated to about 75°C, it is - oo then thermally treated at about 80 to 85°C, by indirect treatment, for example by means of a tubular or plate exchanger for 1 to 30 s or by direct treatment for i. 30 about 3 to 5 s at about 120 to 130°C by direct injection of steam. This heat treatment may be preferably followed by a flash decompression at about oo oo 70 to 80°C.
E © 35 In the case where the whey product is dissolved : directly in the whole milk, the thermally treated concentrate is preferably subjected to a two-stage oo ~ homogenization which may be carried out at a . ~ temperature of about 70 to 75°C. The first stage is at p ® Ce a pressure of about 190 to 210 bar, the second is at about 30 to 50 bar.
According to a variant which is preferably applicable to the case where fresh whole milk in which the whey is directly dissolved is used as starting material, an additional homogenization of the concentrate is carried out prior to or after the preheating, and before the heat treatment.
The temperature of the thermally treated concentrate is advantageously reduced to about 4 to 8°C. A sample is : removed so as to carry out the sterilization tests from which the quantities of water and of stabilizing salt : (sequestering agent) to be added to the solution are determined. The stabilizing salt, in an amount of 0 to about 0.15% by weight is dissolved in the water and incorporated into the lactic solution in order to ensure standardization of the said solution.
Finally, the containers intended for sale are filled with the milk substitute thus obtained, ensuring that an empty space is left above the level of the liquid so oo as to make it possible to stir the content of the container before use. The sterilization is preferably carried out for about 12 to 15 min at about 115 to . 122°C after having preheated the product to about 95 to : 30 The examples below illustrate the invention. In these : examples, the percentages and parts are by weight, - : unless otherwise indicated.
Example 1 : - | ~ ‘The carrageenan and 50% of disodium hydrogen phosphate, as sequestering agent, are dissolved in a first vessel : containing deionized water at 65°C by recirculating the water through a powder dispenser containing the two
- abovementioned ingredients. A sweet whey powder from ~ cheesemaking is dissolved in the same manner by recirculation of the same water supplemented with carrageenan and sequestering agent by the same powder dispenser containing, this time, the whey powder, so as to obtain a solution containing 0.02% of carrageenan, 0.1% of disodium hydrogen phosphate and 20% of solids.
To allow the rehydration of the whey proteins, it is important to allow the solution thus obtained to stand for about thirty minutes at 60°C.
The whey solution is mixed with fresh whole milk at 20°C in a second vessel with stirring in order to ensure good mixing. The proportions are 10.5% of fresh skimmed milk solids per 7% of sweet whey powder in the water.
The next step consists in incorporating the lecithin and the palm oil into the lactic solution. For that, - 20 the solution is heated at 65°C. Separately, the - lecithin is mixed with the palm oil and the mixture is heated to 65°C. The quantity of mixture used corresponds to the quantity of lactic fat which was removed in replacing a portion of whole milk with sweet whey. The fatty phase, representing 7.5% including 0.2% . of lecithin, is mixed with the lactic solution on-line "with the aid of a static mixer. ~~An indirect pasteurization is then carried out at 85°C _ 30 for 30 ss before subjecting the lactic solution to evaporation in a falling £ilm and triple-effect evaporator to a dry matter content of 28%, the oo temperature of the concentrate at the outlet of the evaporator being 35-40°C. The concentrate is then subjected to preheating at 75°C, to a direct heat treatment at 105°C for 5 s by injection of steam, oo + followed by a flash decompression and to a two-stage homogenization, in the the first at 70°C at a pressure
® of 200 bar, and then in the second at 30 bar at the same temperature.
To test the sterilization, the lactic solution is cooled to 6°C. On the basis of the sterilization test, ~ the solution is standardized to 25% dry matter content with demineralized water containing, in dissolved form, the necessary quantity of sequestering agent. To ensure good dispersion of the sequestering agent, the solution should be well mixed before passing to the next stage.
Tins are then filled with the lactic solution : continuously and in a standard manner, leaving an empty space between the liquid and the tin cover. After the : 15 filling phase, the product is preheated to 95°C and then it is sterilized in its packaging at 118°C for 12 min. The tinned milk substitute thus obtained is ready for sale.
Example 2
This example relates to a milk substitute prepared from : whole milk. Disodium hydrogen phosphate is dissolved in oo . the milk, standardized to 7.5% fat by addition of cream and lecithin, and then carrageenan is added thereto
Deo until complete dissolution is obtained. Sweet whey powder is then mixed in and the mixture is maintained stirring for 10 h so as to obtain complete hydration of . the whey proteins. :
All the stages of the process are similar to those of - Example 1, apart from the fact that directly after the evaporation, that is to say before the preheating and ‘the heat treatment, the concentrate is subjected to a : 35 first homogenization (in addition to that carried out after the heat treatment in Example. 1) at 200 bar, and ~ then 30 bar and that the heat treatment which follows : : takes place at 135°C for 5 s. CT.
= Example 3
The procedure is carried out as in Example 2, apart from the fact that the homogenization takes place
Dbetween the preheating and the heat treatment, and that the heat treatment is carried out at 105°C for 5 s.
