Abstract
An edible fat blend comprising monounsaturated fatty acids which constitute 25% to 80% by weight of the fat blend; the monounsaturated fatty acids are derived from at least olive oil which constitutes at least 25% by weight of the fat blend. Also disclosed is an edible spread comprising the edible fat blend and a method of preparation of said spread.
Description
The present invention relates to an edible fat blend, and an edible spread comprising the fat blend, as well » as to a method for preparing the edible spread.
High blood cholesterol is known to be a contra-factor 5 for coronary heart disease. Blood cholesterol comprises two main fractions, namely, low density lipoprotein cholesterol and high density lipoprotein cholesterol. Low density lipoprotein cholesterol has been identified as the main fraction connected to coronary heart disease. Low density lipoprotein cholesterol tends to build up and line the arteries, thus leading to coronary heart disease. On the other hand, high density lipoprotein cholesterol tends to have a scavenging effect and prevents the build up of low density lipoprotein cholesterol on the arteries.
It has been known for some time that the intake of saturated fatty acids has little or no effect on high density lipoprotein cholesterol. However, saturated fatty acids lead to a rise in low density lipoprotein cholesterol. For this reason, spreads and other foodstuffs high in saturated fatty acids have been recommended against. In an effort to reduce coronary heart disease, spreads and other foodstuffs high in polyunsaturated fatty acids have been widely promoted for many years due to the fact that the intake of ' polyunsaturated fatty acids tends to reduce low density lipoprotein cholesterol in the blood.
However, it is has now been found that as well as reducing the level of low density lipoprotein cholesterol in the blood, polyunsaturated fatty acids have the adverse effect of also depressing the level of high density lipoprotein cholesterol in the blood.
Accordingly, the value of spreads and other foodstuffs containing polyunsaturated fatty acids for reducing coronary heart disease is now questionable.
There is therefore a need for an edible spread and an 10 edible fat blend which does not suffer from the disadvantages of those spreads and foodstuffs high in polyunsaturated fatty acids.
The present invention is directed towards providing such a spread and fat blend and the invention is also directed to a method for producing the spread.
According to the invention, there is provided an edible fat blend comprising a blend of fatty acids, the blend comprising monounsaturated fatty acids which constitute in the range of 25% to 80% by weight of the fat blend, the monounsaturated fatty acids being derived partly from olive oil, and partly from rapeseed oil, the olive oil constituting at least 25% by weight of the fat blend.
Preferably, the olive oil constitutes in the range of
% to 80% by weight of the fat blend, and advantageously, the olive oil constitutes in the range of 30% to 75% by weight of the fat blend. In preferred embodiments of the invention, the olive oil constitutes in the range of 30% to 70% by weight of the fat blend.
In some aspects of the invention, the monounsaturated fatty acids are partly derived from one or more of the following additional vegetable oils:
canola oil, a genetically engineered sunflower oil sold under the trade name TRISUN, peanut or ground nut oil, soya bean oil, and palm oil.
In one embodiment of the invention, the additional vegetable oil constitutes up to 50% by weight of the fat blend, and preferably, the additional vegetable oil constitutes in the range of 25% to 50% by weight of the fat blend.
Preferably, the rapeseed oil constitutes in the range of 10% to 50% by weight of the fat blend.
Advantageously, the rapeseed oil constitutes in the range of 25% to 40% by weight of the fat blend.
Preferably, the olive oil is refined and de-odourized, and preferably, additional vegetable oils are also refined and de-odourized.
In another embodiment of the invention, the fat blend comprises a relatively hard fat. This is particularly desirable where the fat blend is for subseguent use as an edible spread.
Preferably, the relatively hard fat constitutes in the range of 15% to 60% by weight of the fat blend, and advantageously, the relatively hard fat constitutes in the range of 20% to 40% by weight of the fat blend, and in certain cases, the relatively hard fat constitutes in the range of 23% to 37% by weight of the fat blend.
In preferred embodiments of the invention, the relatively hard fat may be selected from any one or more of the following relatively hard fats:
butter fat, a higher melting point butter fat fraction, and hardened vegetable oil.
Where the relatively hard fat is hardened soya bean oil, it is preferable that the soya bean oil should constitute in the range of 20% to 40% by weight of the fat blend, and where the relatively hard fat is butterfat, it is preferable that the butter fat should constitute in the range of 30% to 60% by weight of the fat blend.
In a preferred embodiment of the invention, the monounsaturated fatty acids constitute in the range of 30% to 75% by weight of the fat blend, and preferably, the monounsaturated fatty acids constitute in the range of 40% to 70% by weight of the fat blend.
Additionally, the fat blend con^>rises saturated fatty acids, and preferably, the saturated fatty acids constitute in the range of 5% to 50% by weight of the fat blend. Advantageously, the saturated fatty acids constitute in the range of 10% to 45% by weight of the fat blend, and, in general, the saturated fatty acids constitute in the range of 15% to 40% by weight of the fat blend.
Further, the fat blend comprises polyunsaturated fatty acids, the polyunsaturated fatty acids constituting in the range of 5% to 50% by weight of the fat blend, and, preferably, the polyunsaturated fatty acids constitute in the range of 7% to 30% by weight of the fat blend.
Additionally, the invention provides an edible spread comprising a fat phase and an aqueous phase, the fat phase comprising the fat blend according to the invention, and constituting in the range of 5% to 95% by weight of the spread, and preferably, the fat phase *
constitutes in the range of 15% to 85% by weight of the spread, and, advantageously, the fat phase constitutes - ** in the range of 20% to 80% by weight of the spread.
In some examples, the fat phase comprises an emulsifying agent, and preferably, the emulsifying agent is selected from any one or more of the following emulsifying agents:
lecithin, mono and diglycerides, and polyglycerol fatty acid ester.
In most examples of the invention, the' emulsifying agent constitutes not more than 5% by weight of the fat phase.
In most examples of the invention, the aqueous phase comprises water.
In some examples of the invention, the aqueous phase comprises a stabilising agent, and preferably, the stabilising agent is selected from any one or more of * the following stabilising agents:
* gelatine, carrageenin, maltodextrin, pectin, sodium alginate, and salts of alginic acid such as its sodium salt.
In most examples of the invention, the stabilising agent constitutes not more than 10% by weight of the aqueous phase.
In some examples of the invention, the aqueous phase comprises a protein additive, which is preferably selected from any one or more of the following additives:
skimmed milk, buttermilk, whey, reconstituted skimmed milk powder, reconstituted whey powder, milk proteins, vegetable proteins, and lactic cultures.
In most examples of the invention, the protein additive constitutes not more than 15% by weight of the aqueous phase.
Further, the invention provides a method for preparing an edible spread, the method comprising the step of forming a water-in-oil emulsion by dispersing an aqueous phase to a fat phase, wherein the fat phase comprises the fat blend according to the invention.
Preferably, the fat phase constitutes in the range of
% to 95% by weight of the water-in-oil emulsion, and «.
advantageously, the fat phase constitutes in the range of 15% to 85% by weight of the water-in-oil emulsion.
In most examples of the invention, the water-in-oil emulsion is maintained at a temperature in the range of 35°C to 55°C during mixing, and preferably, the waterin-oil emulsion is maintained at a temperature in the range of 40°C to 50°C during mixing. In a preferred example of the invention, the water-in-oil emulsion is maintained at a temperature of approximately 45 °C during mixing.
It is preferable that the water-in-oil emulsion is formed by shear agitation.
The advantages of the invention are many. A particularly important advantage of the invention is that intake of the edible fat and the spread should reduce the risk of coronary heart disease. This is achieved by virtue of the fact that the edible fat blend and edible spread contain monounsaturated fatty acids, and it has been found that the intake of monounsaturated fatty acids lowers low density lipoprotein cholesterol in the blood with virtually no effect on high density lipoprotein cholesterol, accordingly reducing the risk of coronary heart disease. A further advantage of the fat blend and spread according to the invention is that both provide a balance between fat intake and nutrition.
The invention will be more clearly understood from the 5 following description of some preferred examples thereof, which are given solely for the purposes of illustrating the invention and are not in any way intended to limit the scope of the invention.
In each example, an edible spread according to the invention is prepared using a method according to the invention. A water-in-oil emulsion is prepared from an aqueous phase and a fat phase. In each example, the fat phase is an edible fat blend also according to the invention which comprises monounsaturated fatty acids.
The monounsaturated fatty acids are derived from olive oil and rapeseed oil. In all the examples, some of the monounsaturated fatty acids is also derived from hardened soya bean oil. The olive oil and rapeseed oil used in the examples is refined and de-odourized. The monounsaturated fatty acids content of the olive oil is 70% by weight, the polyunsaturated fatty acids content of the olive oil is 16% by weight and the saturated fatty acids content of the olive oil is 14% by weight. The rapeseed oil used in the Examples has a monounsaturated fatty acids content of 63% by weight, a polyunsaturated fatty acids content of 30% by weight, and a saturated fatty acids content of 6% by weight.
In all cases, the fatty acids content of the olive oil and rapeseed oil given above is the content after refining and de-odourizing.
The hardened soya bean oil used in the examples is refined and de-odourized and has a slip point of 41°C. Although needless to say, the slip point may lie in the range of 36°C to 42°C.
In the examples, the fat phase and aqueous phase are prepared simultaneously, although needless to say, this is not necessary.
Example 1
In this example, the fat blend is prepared from the following ingredients in the percentages by weight of the total fat blend set out below:
olive oil rapeseed oil — 34.2% 32.9% hardened soya bean oil - 31.5% mono and diglycerides - 1.2% beta carotene 0.007%
The fats, namely, olive oil, rapeseed oil and hardened soya bean oil are heated to approximately 45°C and blended together. The beta carotene which acts as a colouring agent is blended with the fats. The mono and diglycerides which act as emulsifying agents are then blended with the blended fats. The fat blend which forms the fat phase for the spread is maintained at a temperature of approximately 45°C during blending.
The aqueous phase is prepared from the following ingredients in the percentages by weight of the total aqueous phase set out below:
water - 94% salt - 2.5% sodium alginate - 1.6% whey powder - 0.8% potassium sorbate - 0.16% lactic acid - 0.05% approximately.
The water at a temperature of approximately 75 °C and the salt are thoroughly mixed, and the whey powder which contains protein and acts as a protein additive is blended in with the water and salt mix. The potassium sorbate, which acts as a preservative, is also blended with the water and salt mix. The pH of the aqueous phase is adjusted to 6 to 6.4 by the addition of the lactic acid. The sodium alginate which acts as a stabilising agent is also blended with the water and salt mix. The temperature of the aqueous phase is adjusted to approximately 45°C.
The edible spread is prepared by preparing a water-inoil emulsion. The aqueous phase at a temperature of approximately 45 °C is dispersed in the fat phase which is also at approximately 45°C in the proportion of sixty parts by weight of the aqueous phase to forty parts by weight of fat phase. The water-in-oil emulsion is formed by subjecting the dispersion of aqueous phase and fat phase to shear agitation for a period of fifteen minutes while the temperature is maintained at 45°C.
The water-in-oil emulsion is then pasteurized at a temperature of 80°C for ten seconds in a scraped surface pasteurizer, and is chilled and crystallized in a scraped surface heat exchanger. The spread is then ready for use and is suitable for packing in a tub.
On analysis, it has been found that the spread prepared according to this example has acceptable physical and organoleptic properties.
The fat blend constitutes 40% by weight of the total weight of the spread of this example. Of the fatty acids of the fat blend, approximately 16% by weight are saturated, and 84% by weight are unsaturated. Monounsaturated fatty acids constitute 63% by weight of the fat blend, while polyunsaturated fatty acids constitute 21% by weight of the fat blend.
Accordingly, the monounsaturated fatty acids constitute approximately 25% by weight of the spread, the polyunsaturated fatty acids constitute approximately 8% by weight of the spread, and saturated fatty acids constitute approximately 6% by weight of the spread.
Example 2
In this example, the fat blend is prepared from the following ingredients in the percentages by weight of the total fat blend set out below:
olive oil - 33.3% rapeseed oil - 33.3% hardened soya bean oil - 33.0% lecithin - 0.33% beta carotene 0.002%
The fats, namely, olive oil, rapeseed oil and hardened soya bean oil are heated to approximately 45°C and blended together. The beta carotene which acts as a colouring agent, and the lecithin which acts as an emulsifying agent are blended with the blended fats. The fat blend which forms the fat phase for the spread is maintained at a temperature of approximately 45°C during blending.
The aqueous phase is prepared from the following
Ingredients in the percentages by weight of the total aqueous phase set out below:
water - 91% salt - 9%
The water is heated to approximately 75°C and the salt is thoroughly mixed with the water to form the aqueous phase. The temperature of the aqueous phase is adjusted to 45°C.
The edible spread is prepared by preparing a water-inoil emulsion. The aqueous phase at a temperature of approximately 45 °C is dispersed in the fat phase which is also at approximately 45 °C in the proportion of twenty parts by weight of aqueous phase to eighty parts by weight of fat phase. The water-in-oil emulsion is formed by subjecting the dispersion of aqueous phase and fat phase to shear agitation for a period of ten minutes while the temperature is maintained at 45°C.
The water-in-oil emulsion is then pasteurized at a temperature of 80 °C for ten seconds in a scraped surface pasteurizer, and is chilled and crystallized in a scraped surface heat exchanger. The spread is then ready for use and is suitable for packing in a tub.
On analysis, it has been found that the spread prepared according to this example has acceptable physical and organoleptic properties.
The fat blend constitutes 80% by weight of the total weight of the spread of this example. Of the fatty acids of the fat blend, approximately 15% by weight are saturated and 85% by weight are unsaturated.
Monounsaturated fatty acids constitute 68% by weight of the fat blend, while polyunsaturated fatty acids constitute 17% by weight of the fat blend.
Accordingly, monounsaturated fatty acids constitute 10 approximately 54% by weight of the spread, polyunsaturated fatty acids constitute approximately 14% by weight of the spread, and saturated fatty acids constitute approximately 12% by weight of the spread.
Example 3
In this example, the fat blend is prepared from the following ingredients in the percentages by weight of the total fat blend set out below:
olive oil - 34% rapeseed oil - 32.1% hardened soya bean oil - 32.5% mono and diglycerides - 1.4% beta carotene — 0.002%
The fats, namely, olive oil, rapeseed oil and hardened soya bean oil are heated to approximately 45°C and blended together. The beta carotene which acts as a colouring agent and the mono and diglycerides which act as an emulsifying agent are blended with the fats. The fat blend which forms the fat phase for the spread is maintained at a temperature of approximately 45°C.
The aqueous phase is prepared from the following ingredients in the percentages by weight of the total aqueous phase set out below:
water - 95.0% salt 2.33% whey powder 1.67% sodium alginate 0.83% potassium sorbate 0.17% lactic acid 0.05% approximately
The water at approximately 75°C and salt are thoroughly mixed together. The whey powder which contains protein is blended with the water and salt mix. The potassium sorbate which acts as a preservative is also blended with the water and salt mix. The sodium alginate which acts as a stabilising agent is then blended with the mixture. The pH of the aqueous phase is adjusted to
6.2 by the addition of lactic acid. The temperature of the aqueous phase is adjusted to approximately 45°C.
The edible spread is prepared by preparing a water-inoil emulsion. The aqueous phase at a temperature of
45°C is dispersed in the fat phase which is also at approximately 45° in the proportion of sixty parts by weight of aqueous phase to forty parts by weight of fat phase. The water-in-oil emulsion is formed by subjecting the dispersion of aqueous phase and fat phase to shear agitation for a period of fifteen minutes, while the temperature is maintained at 45°C.
In this example, a suitable flavouring agent is added to the water-in-oil emulsion during agitation. Such flavouring additives will be well known to those skilled in the art.
The water-in-oil emulsion is then pasteurized at a temperature of 80°C for ten seconds in a scraped surface pasteurizer, and is chilled and crystallised in a scraped surface heat exchanger. The spread is then ready for use and is suitable for packing in a tub.
On analysis, it has been found that the spread prepared according to this example has acceptable physical and organoleptic properties.
The fat blend constitutes 40% by weight of the total 20 weight of the spread of this example. Of the fatty acids of the fat blend, approximately 15% are saturated and 85% are unsaturated. Monounsaturated fatty acids constitute 67% by weight of the fat blend, while polyunsaturated fatty acids constitute 18% by weight of the fat blend. Accordingly, monounsaturated fatty acids constitute approximately 27% by weight of the spread, polyunsaturated fatty acids constitute approximately 7% by weight of the fat spread, and saturated fatty acids constitute approximately 6% by weight of the spread.
The solid fat profile of the spreads of Examples 1 to 3 is in the range of:
N5 is in the range of 30 to 40
N10 is in the range of 25 to 35 N15 is in the range of 15 to 25 N20 is in the range of 12 to 18 N25 is in the range of 6 to 10 N30 is in the range of 3 to 7 N35 is in the range of 0 to 4 N40 is in the range of 0 to 2.
Accordingly, all the spreads prepared according to the examples are suitable for packing in tubs, for example, tubs of plastics material.
Should it be desired to produce the spreads suitable for foil or paper wrapping, the fat profile of the spreads would be in the range of:
N5 is in the range of 50 to 60 N10 is in the range of 35 to 45 N15 is in the range of 20 to 30
N20 is in the range of 15 i to 25 N25 is in the range of 6 to 10 N30 is in the range of 3 to 7 N35 is in the range of 0 to 4 N40 is in the range of 0 to 2.
By increasing the proportions of the relatively hard fats in the fat phase of the examples, the above fat profile would be obtained. This will be well known to those skilled in the art.
The advantages of the spreads produced according to
Examples 1 to 3 are many. In particular, the spreads contain monounsaturated fatty acids, which constitute a relatively high proportion of the total unsaturated fatty acids. As can be seen in all examples, the monounsaturated fatty acids constitutes between 50% and almost 70% by weight of the fatty acids, and between 13% and 54% by weight of the spread. It is believed that by virtue of this, intake of the spreads should lead to a significant lowering of low density lipoprotein in cholesterol in the blood, while at the same time having relatively no effect on high density lipoprotein cholesterol in the blood. Furthermore, the spreads are relatively high in protein. Furthermore, the addition of protein additives such as whey powder and the addition of sodium caseinate to the aqueous phase further enhances the protein content of the spreads, and in turn their nutritional value.
While in all the examples, the fat blend has been used in the preparation of an edible spread, it will be readily apparent to those skilled in the art that the fat blend could be used for preparing other foodstuffs, for example, mayonnaise, salad dressing and the like.
Of course, it will be appreciated that the fat blend may be used in any other foodstuffs.
Needless to say, while it is preferable, it is not essential that the fat phase and aqueous phase should be at the same temperature prior to mixing. In fact, once the fat phase is maintained at a temperature in the range of 35°C to 55°C, it is believed that this should be sufficient.
While in the examples, fat blends comprising specific proportions of fats which comprise monounsaturated fatty acids have been described, the relative proportions of fats comprising monounsaturated fatty acids may vary considerably.
Needless to say, other suitable agitating means, t pasteurizing means and chilling means may be used as desired.
