APPLICATION FOR PATENT

TITLE: Emulsions and Methods of Preparation Thereof INVENTORS: Ovadia Itamar EDERY and David GILAD

RELATED APPLICATIONS:

This application claims the benefit under 35 U.S.C. § 119(e) of provisional application US 62/292282 filed February 6, 2016 and entitled "IMPROVED FOOD PRODUCTS COMPRISING OIL-IN-WATER DROPLETS WITH NATURAL THICKENER AS AN EMULSIFYING AGENT"; which is fully incorporated herein by reference.

FIELD OF THE INVENTION

The invention is the field of emulsion technology.

BACKGROUND OF THE INVENTION

Solid oil based products, such as margarine, butter, lard and shortening are standard ingredients in commercial baking. Many solid oil based products are produced by hydrogenation of oils, which are liquid at room temperature. Hydrogenation raises the melting point causing the oil to remain in the solid phase at room temperature.

Hydrogenation results in creation of trans-fatty acids. Public perception of trans- fats as "unhealthy" has led to the development of trans-fat free products, which are solid or spreadable, as opposed to liquid. Processes such as interesterification, fractionation, and the addition of monoglycerides and/or diglycerides are typically used to make the non-liquid trans-fat free products.

However, public perception of these alternative products as "unhealthy" is growing.

SUMMARY OF THE INVENTION

One aspect of some embodiments of the invention relates to use of arrowroot powder as an emulsifier in emulsions, which do not contain a conventional surfactant, and/or emulsifier (such as lecithin or non-lecithin conventional emulsifiers). In some embodiments the arrowroot comprises Canna Indica (hereinafter "Canna").

Another aspect of some embodiments of the invention relates to use of arrowroot powder as a stabilizer in emulsions containing a conventional surfactant and/or emulsifier (such as lecithin), a plant derived oil, and water.

Alternatively or additionally, in some embodiments melting 410 has a duration of at least 10 minutes. In some exemplary embodiments of the invention, maintaining a temperature of at least 70 °C for at least 10 minutes during melting 410 melts all existing crystal structures completely.

These processes are set forth hereinbelow in Examples 13 and 14.

Exemplary crystal state manipulation considerations

Coconut oil has different crystalline structures. There are Alpha crystals, which are unstable and with time usually revert to Beta, and Beta Prime crystals. Beta prime crystals have the highest melting point compared to Alpha and Beta crystals.

Beta Prime crystals contribute to a shiny appearance and/or a smooth texture similar to chocolate, which is processed to achieve a Beta Prime crystal structure in the Cocoa butter.

The ability to control the crystallization of coconut fat contributes to an ability to manipulate texture and mouthfeel in margarine and when creating a whippable product based on coconut fat. Many additional products would benefit from the ability to manipulate the crystallization of coconut fat to achieve a desired crystal structure. For example, Margarine, spreads and chocolate based on coconut oil instead of cocoa butter.

In some exemplary embodiments of the invention, a predominantly beta prime fat is achieved by melting the fat to ensure the existing crystal network is destroyed and cooling to create beta crystals followed by reheating to melt alpha crystals and tempering to melt Alpha crystals and to force unstable crystals to Beta Prime structure.

The methods depicted in Fig. 3 and 4 as well as Examples 13 and 14 illustrate exemplary ways to achieve these goals.

Exemplary advantages

In some exemplary embodiments of the invention, use of an emulsion containing water reduces the caloric content of a food product (e.g. margarine or mayonnaise).

EXAMPLES

Reference is now made to the following examples, which together with the above descriptions, illustrate the invention in a non-limiting fashion.

The following materials and methods are used in performance of experiments described in examples hereinbelow:

Materials:

Lecithin: Soy lecithin and de-oiled sunflower lecithin were used interchangeably with similar results.

Soy lecithin was Organic soy lecithin (Oleoland, Ukraine; Origin, India) Sunflower lecithin was European Deoiled non GMO pure sunflower lecithin, (Ivivotal, Germany).

Coconut oil: RBD (refined, bleached, and deodorized) Coconut oil from Do-It (Netherlands) prepared from Phillipine oil. Fat is not hydrogenated or interesterified, Similar results were achieved with virgin coconut oil (data not shown).

Maranta Arundinacea starch (Banana Rhizome extract): (Bergwerf, India) commonly known as East Indian arrowroot.

Canna Indica starch: (Amarlane foods; Israel) Starch was produced using standard starch extraction process. Canna indica roots were washed, cleaned, washed again, drained, pulped, sieved dryed and packed. No additives were introduced.

Curcuma Angustifolia starch: (Sheily indo proteins, India) Also commonly known as East Indian arrowroot.

Equipment:

Blender: Vitamix - VMFS019 (Vitamix Corporation; Cleveland OH; USA) EGL1 crystallizer- EGLI, Butchwill, Switzerland. Adamas (Heat Exchanger )-Butter extruder machine, (Agropois, Ukraine)

Glycol based cooling system- Generic chiller ( EGLI, Butchwill, Switzerland). Ammonia based cooling system-G n nc chiller ( EGLI, Butchwill, Switzerland). Ice water based cooling system- Generic water based chiller (Agropois, Ukraine).

EXAMPLE 1:

Maranta Arundinacea as

an Emulsion Stabilizer

In order to examine the possibility of using Maranta Arundinacea as an emulsion stabilizer, the following recipe was used:

RBD Coconut oil 66%

Water 32%

lecithin 0.2%

Maranta Arundinacea starch 1.8%

All ingredients were brought to 30 degrees centigrade. The lecithin was dissolved in the liquid coconut oil to make an oil phase and the starch was dissolved in water to make a water phase. The water phase was placed in the blender at speed setting 8. The oil phase was added gradually until a homogeneous mixture was achieved. The emulsion texture was similar to heavy cream and was stable for 15 minutes. This time was sufficient for refrigeration to crystallize the coconut oil to create a margarine like product. Crystallization (as detailed in Fig. 3 and accompanying descriptive text as well as examples 13 and 14 hereinbelow) produced a margarine like product with no discernible separation of oil and water. Use of starch permitted use of less lecithin than similar processes without starch as well as thickening texture and prolonging the coalescence of oil droplets.

EXAMPLE 2:

Low amounts of Maranta Arundinacea

are Ineffective for Emulsion Stabilization

In order to examine the possibility of using significantly less Maranta

Arundinacea as an emulsion stabilizer, the following recipe was used:

RBD Coconut oil 67%

Water 32.6%

lecithin 0.2%

Maranta Arundinacea starch 0.2% The process was as described above in Example 1. The resultant mixture was thin and liquid with oil and water phases clearly visible. This example illustrates that 0.2% Maranta Arundinacea starch is insufficient for emulsion stabilization.

EXAMPLE 3:

Higher amounts of Maranta Arundinacea

Thicken the Emulsion

In order to examine the possibility of using significantly more Maranta

Arundinacea as an emulsion stabilizer, the following recipe was used:

RBD Coconut oil 66%

Water 31%

lecithin 0.5%

Maranta Arundinacea starch 2.5%

The process was as described above in Example 1 except that the blender speed was 4. The resultant mixture had a mayonnaise like texture with no discernible separation of oil and water phases during 15 minutes. This time was sufficient for refrigeration to crystallize the coconut oil. Crystallization (as detailed in Fig. 3 and accompanying descriptive text as well as examples 13 and 14 hereinbelow) produced a margarine like product with no discernible separation of oil and water. This example suggests that 2.5% starch thickens the emulsion considerably.

EXAMPLE 4:

Higher amounts of Lecithin

Reduce Emulsiuon Stability

In order to examine the possibility of Maranta Arundinacea as an emulsion stabilizer in the presence of high amounts of lecithin, the following recipe was used:

RBD Coconut oil 66%

Water 30%

lecithin 2.5%

Maranta Arundinacea starch 1.5%

The process was as described above in Example 3. The resultant mixture had a mayonnaise like texture initially, but quickly separated into oil and water phases. There was not sufficient time for refrigeration to crystallize the coconut oil. This example shows excess lecithin, widely regarded as an emulsifying agent, prevents the arrowroot from properly stabilizing the emulsion. Examples 1-4 illustrate that 1.8% to 2.5% starch in the presence of 0.2 to 0.5% Lecithin can stabilize an emulsion based on 66% oil and water for sufficient time to make a margarine like product.

EXAMPLE 5:

Canna Indica as

an Emulsion Stabilizer

In order to examine the possibility of using Canna Indica as an emulsion stabilizer, the following recipe was used:

RBD Coconut oil 66.8%

Water 32%

lecithin 0.2%

Canna Indica starch 1.0% All ingredients were brought to 30 degrees centigrade. The lecithin was dissolved in the liquid coconut oil to make an oil phase and the starch was dissolved in water to make a water phase. The water phase was placed in the blender at speed setting 4. The oil phase was added gradually until a homogeneous mixture was achieved. The emulsion texture was similar to heavy cream and was stable for up to 48 hours or more at up to 82° C. Crystallization (as detailed in Fig. 3 and accompanying descriptive text as well as examples 13 and 14 hereinbelow) produced a margarine like product with no discernible separation of oil and water. Use of 1.0% Canna starch properly stabilized the emulsion as effectively as or more effectively than mono and diglycerides commonly used to for the same function. This example, together with Example 1, suggests that Canna Indica starch is a more effective stabilizer than Maranta Arundinacea starch.

EXAMPLE 6:

Increasing Lecithin Amount Does Not Reduce

Effectiveness of Canna Indica as an Emulsion Stabilizer

In order to examine the possibility of using higher amounts of lecithin with Canna Indica, the following recipe was used:

RBD Coconut oil 66.8%

Water 32%

lecithin 1.0%

Canna Indica starch 1.0%

The process was as described above in Example 5. As in Example 5, the emulsion texture was similar to heavy cream and was stable for up to 48 hours or more at up to 82° C. Crystallization (as detailed in Fig. 3 and accompanying descriptive text as well as examples 13 and 14 hereinbelow) produced a margarine like product with no discernible separation of oil and water. This example, together with Example 4, suggests that Canna Indica starch is a more effective stabilizer in the presence of high amounts of lecithin than Maranta Arundinacea starch.

EXAMPLE 7:

Increasing Oil to Water Ratio Does Not Reduce

Effectiveness of Canna Indica as an Emulsion Stabilizer

In order to examine the possibility of using Canna Indica for oil in water emulsions, the following recipe was used:

RBD Coconut oil 82%

Water 16.5%

lecithin 0.5%

Canna Indica starch 1.0%

The process was as described above in Example 5. As in Example 5, the emulsion texture was similar to heavy cream and was stable for up to 48 hours at up to 82° C. Crystallization produced a margarine like product with no discernible separation of oil and water. This example, together with Example 4, suggests that Canna Indica starch is a more effective stabilizer in the presence of high amounts of lecithin than Maranta Arundinacea starch.

EXAMPLE 8:

Canna Indica as an Emulsifier

In order to examine the possibility of using Canna Indica without a conventional emulsifier, the following recipe was used:

RBD Coconut oil 67%

Water 32%

lecithin NONE

Canna Indica starch 1.0%

The process was as described above in Example 5 except that no lecithin was added to the oil. The emulsion texture was mayonnaise like and was stable indefinitely. This example demonstrates the possibility of making a reduced fat mayonnaise like or spread product using starch as an emulsifier instead of lecithin. These results suggest that similar results can be achieved in any process where there is no rapid heating of the product.

EXAMPLE 9:

Low Amounts of Canna Indica as an Emulsifier In order to examine the possibility of reducing the amount of Canna Indica, the following recipe was used:

RBD Coconut oil 66.5%

Water 33%

lecithin NONE

Canna Indica starch 0.5%

The process was as described above in Example 8 except that ingredient were brought to 40 degrees centigrade. The emulsion texture was similar to heavy cream and was stable indefinitely. This example demonstrates the possibility of making a reduced fat cream like product using canna starch as an emulsifier instead of lecithin or other non- lecithin conventional emulsifying agents.

EXAMPLE 10:

Canna Indica as an Emulsifier in an Oil in Water Emulsion

In order to examine the possibility of reducing the amount of oil in the emulsion, the following recipe was used:

RBD Coconut oil 30%

Water 68%

lecithin NONE

Canna Indica starch 2%

The process was as described above in Example 8. The emulsion texture was similar to heavy cream and was stable indefinitely. This example demonstrates the possibility of using Canna starch for an oil in water emulsion as well, making a cream like product with only 30% fat using starch as an emulsifier instead of lecithin or any other conventional emulsifying agent.

EXAMPLE 11:

Influence of Arrowroot Type and

Amount on Properties of Emulsion Including Lecithin

Different amounts and types of Arrowroot Starch were tested to determine the amount of starch needed to stabilize a water in oil emulsion using 0.15% - 2.85% of oil weight of lecithin as the surfactant (emulsifier) and using Arrowroot Starch as the stabilizer to prevent the coalescence of oil droplets. Results were as follows:

Maranta stabilized the emulsion for up to 15 minutes.

Canna Starch was found to be effective when the water to oil ratio was between 15%-33% of the oil weight for much longer. Tests showed that varying the amount of Canna Starch in the range of 0.23% - 2.9% of water weight changed emulsion properties dramatically. 1.4% Canna starch gave a solid emulsion similar to butter or margarine, while lower or higher percentages gave softer emulsions.

EXAMPLE 12:

Influence of Canna Starch

Amount on Properties of Emulsion without Lecithin

Different amounts of Canna Starch were tested to determine the amount of starch needed to stabilize an emulsion without lecithin. Emulsions were stable indefinitely at all tested concentrations.

Results were as follows:

Results of this example, together with those of example 11, suggest that water/oil emulsions with a wide range of textures can be prepared using canna starch as the sole emulsifier.

EXAMPLE 13:

Motion Crystallization of Coconut Oil Based Emulsions

In order to create a beta prime coconut oil crystal structure in an emulsion, the following protocol was performed.

An emulsion was prepared as in Example 1.

The emulsion was placed in an EGLI crystallizer. The oil in the emulsion was melted by heating to 70 °C for ten minutes.

The outer shaft of the crystallizer was cooled to -9°C while scraping the crystallized oil from the inside shaft. This process is believed to create beta crystals.

The inner shaft of the crystallizer was heated above the melting temperature of alpha crystals in order to achieve a beta prime stable fat. The process is complete when the emulsion exiting the crystallizer reaches 21.5 °C to 23 °C.

Heat created by friction of the pinworker of the crystallizer melts remaining alpha crystals and prevents formation of new beta crystals.

The emulsion was then tempered at 22 °C to 28 °C for 12 hours to promote formation of beta prime crystals as the dominant crystal structure.

Three tests were performed with varying conditions:

In the first test, a beta prime stable product was achieved. In the second test, the fat did not crystallize properly because of insufficient cooling. Too many unstable crystals were present due to the high temperature of the product output from the crystallizer. In the third test the fat was over-cooled to a point where melting of remaining alpha crystals was hard to achieve causing the beta crystals to dominate. This resulted in a product output with a low temperature which is below melting point of alpha crystals.

These three tests suggest that if the four stages of:

Melting fat to destroy crystal network;

Cooling to create beta crystals;

Reheating to melt alpha in order to create beta prime crystals; and

Tempering are performed correctly while output temperature is between 21.5 °C to 23°C, a product with predominately beta prime crystals will result. Settings of equipment can be manipulated to keep the output temperature in the desired range.

EXAMPLE 14:

Stationary Tempering to Control Crystallization of

Coconut Oil and/or Coconut Oil Based Emulsions

In order to increase the amount of beta prime coconut oil crystals in oil and/or an emulsion based on coconut oil, the following protocol was performed.

An emulsion as described in Example 13 was prepared.

A temperature controlled box with a first temperature sensor for the tempering apparatus and a second temperature sensor for the emulsion temperature was prepared using a thermoelectric plate as a temperature regulator.

The oil in the emulsion was melted by heating to 70 °C for ten minutes.

The box temperature was set below 24 °C and the coconut oil in the emulsion was allowed to crystallize, forming beta crystals.

The box temperature was raised above 22 °C, but not above 25 °C, to melt alpha crystals and encourage formation of beta prime crystals.

Remaining alpha crystals were melted by tempering for 12 hours.

Four tests were performed with varying conditions and the results were as follows:

The first test produced a product where beta prime crystals appeared to dominate. In the second test Beta crystals dominated. In order to create beta prime stable product, higher temperature was required at the third stage or alpha won't melt, thus causing the fat to revert to its natural beta crystal structure.

In the third test Beta crystals dominated. In order to create beta prime stable product, higher temperature was required at the third stage or alpha won't melt, thus causing the fat to revert to its natural beta crystal structure. In the fourth test, the fat was melted. During stage 3 fat was heated to a temperature where alpha and beta crystals melted. This prevented controlled melting of alpha crystals, a necessary step to create a beta prime stable fat.

The first, second, third and fourth tests were repeated with RBD coconut oil and similar results were achieved.

EXAMPLE 15:

Curcuma Angustifolia

as an Emulsion Stabilizer

In order to examine the possibility of using Maranta Arundinacea as an emulsion stabilizer, the following recipe was used:

RBD Coconut oil* 66%

Water 32%

lecithin 0.2%

Curcuma angustifolia starch 1.8%

All ingredients were brought to 30 °C and the emulsion was prepared as in Example 1 except that the starch was Curcuma Angustifolia. The speed setting on the blender was 8 and the emulsification temperature was 30 °C. The resultant emulsion had the texture of heavy cream and was stable for about 15 minutes. Curcuma angustifolia starch stabilized the emulsion for sufficient time to complete the production process of a product such a margarine. Once the crystallization takes place it solidifies the product and stabilizes the emulsion. Alternatively or additionally, the starch enriches the emulsion texture allowing the use of less lecithin.

EXAMPLE 16:

Lower Amounts of Curcuma Angustifolia

as an Emulsion Stabilizer

In order to examine the possibility of using lower amounts of Maranta

Arundinacea as an emulsion stabilizer, the following recipe was used:

RBD Coconut oil* 67%

Water 32.6%

lecithin 0.2%

Curcuma angustifolia starch 0.2%

All ingredients were brought to 30 °C and the emulsion was prepared as in

Example 15. The resultant emulsion was thin and liquid and unstable. This test indicates that 0.2% of Maranta Arundinacea starch was an ineffective emulsion stabilizer. EXAMPLE 17:

Higher Amounts of Curcuma Angustifolia

as an Emulsion Stabilizer

In order to examine the possibility of using higher amounts of Maranta Arundinacea an emulsion stabilizer, the following recipe was used:

RBD Coconut oil* 66%

Water 31%

lecithin 0.5%

Curcuma angustifolia starch 2.5%

All ingredients were brought to 30 °C and the emulsion was prepared as in Example 15 except that the speed setting on the blender was 4. The resultant emulsion had a mayonnaise like consistency and was stable for 15 minutes. As in Example 15, Curcuma angustifolia starch stabilized the emulsion for sufficient time to complete the production process of a product such a margarine. Once the crystallization takes place it solidifies the product and stabilizes the emulsion.

EXAMPLE 18:

Curcuma Angustifolia

as an Emulsion Stabilizer with High Amounts of Lecithin In order to examine the possibility of using higher amounts of lecithin, the following recipe was used:

RBD Coconut oil 66%

Water 30%

lecithin 2.5%

Curcuma angustifolia starch 1.5%

All ingredients were brought to 30 °C and the emulsion was prepared as in Example 15 except that the speed setting on the blender was 4. The resultant emulsion had a mayonnaise like consistency but was not stable for any significant amount of time. Surprisingly, increasing the amount of lecithin contributed to a decrease in the stabilizing effect of the Curcuma angustifolia starch.
