Characterization by Viscosity
[0178] In some exemplary embodiments of the invention there is provided a crude tahini composition with a viscosity cP SC4-21 at 5 RPM of 2000, 1700, 1500 or intermediate or lower values or less. Alternatively or additionally, in some embodiments there is provided a crude tahini composition having a viscosity cP SC4-21 at 11 RPM of less than 1796, less than 1700, less than 1633, less than 1400, less than 1000 or intermediate or lower values.
[0179] In some exemplary embodiments of the invention there is provided a whole grain crude tahini composition having a viscosity cP SC4-21 at 11 RPM of 1400 or less, 1300 or less or intermediate or lower values.
[0180] Viscosity data for conventional tahini as well as tahini according to exemplary embodiments of the invention is presented hereinabove in Table 1 and Table 2.
[0181] Adding 100 g of water to 100 g of microfluidized tahini will produce a much lower viscosity than similar dilution of tahini which was not microfluidized. One possible explanation for this observation is that the lower viscosity of the microfluidized crude tahini contributes to a lower viscosity of the emulsion. As a result, in some embodiments the microfluidized tahini is characterized by a lower starchiness as perceived by human tasting panels relative conventional crude tahini. This lower viscosity of the water:tahini emulsion persists for only a few seconds to a few minutes after mixing.
Exemplary Rheology Considerations
[0182] Rheology panels indicate that many people perceive micro fluidized tahini paste sweeter than comparable tahini paste which was not subject to micro fluidization.
[0183] Microfluidized crude tahini exhibits different properties than standard tahini during emulsion preparation. This is apparent when mixing 50 g crude tahini with 30 g water. Standard tahini becomes viscous almost immediately upon mixing. Microfluidized tahini remains thin for 5 to 6 seconds after mixing and then increases in viscosity. A tasting panel of 10 people indicated microfluidized crude tahini does not become viscous in the mouth when mixed with saliva as regular Tahini does. Alternatively or additionally, microlfluidize crude tahini is sweeter than the crude tahini before microfluidization.
[0184] In some exemplary embodiments of the invention there is provided a crude tahini composition which is perceived in organoleptic testing as not becoming sticky in the mouth even after mixing with saliva.
Exemplary Microfluidization Equipment
[0185] Microfluidization equipment suitable for use in the context of various exemplary embodiments of the invention is available from MICROFLUIDICS INTERNATIONAL CORPORATION (Westwood Mass., USA).

[0187] B.E.E. International Inc. (Easton, Mass., USA) also makes microfluidization equipment suitable for use in the context of various exemplary embodiments of the invention, such as the “Micro DeBEE” model.
[0188] Microfluidization is a high-shear fluid process, which provides uniform size reduction. In general, an increase in the amount of pressure applied by microfluidizing equipment contributes to a reduction in average particle size.
Exemplary Microfluidization Protocol
[0189] A microfluidization machine as described above is rinsed with propanol then flushed with sunflower oil at 20,000 PSI. An additional wash with cold-pressed sesame oil at 20,000 PSI is conducted. Crude Tahini (or another sample) is mixed by rolling the container and 2X 200CC samples are taken in cups. Each sample is mixed with a blender until it appears homogenized to produce an initial homogenate.
[0190] A sample of the initial homogenate is loaded into the microfluidizer. A homogenization channel with a 400-micron inlet and 200-micron outlet is fitted and three passages are performed at 25000 PSI. For purposes of this specification and the accompanying claims, the term “homogenization channel” indicates a straight channel.
[0191] The processed material is cooled in a heat diffuser submerged in cold water
[0192] Exit temperature is 50° C. +5 degrees.
[0193] A homogenization channel with a 200-micron inlet and 87-micron outlet is fitted and three additional passages are performed at 25000 PSI.

Processing of Whole Grain Tahini Using Additional Exemplary Microfluidization Protocols
[0199] Whole grain sesame seeds were soaked in water for 3 hours then roasted and ground into tahini using a ball mill. A stone mill or conche or Maclntyre could be substituted. This preserves the natural ratio of hulls:seeds of 7% to 19% on a dry matter basis. In contrast, tahini indicated as “with hulls” in Table 1 and Table 2 (above) is labeled as “whole grain” by the manufacturer but may not contain the natural ratio of hulls: seeds. The resulting whole grain tahini was processed in a MICROFLUIDICS M-110-P homogenizer as described in the preceding section with the changes presented in Table 5A and analyzed for PSD and viscosity using protocols presented hereinbelow.

[0250] In some exemplary embodiments of the invention, the resultant solution of rice bran extract in water is used instead of water in the spray drying protocols above. In some exemplary embodiments of the invention, the resultant solution of rice bran extract in water is microfluidized with mixing with tahini or without mixing with tahini before drying.
[0251] In some exemplary embodiments of the innovation, the result solution of rice bran extract in water is microfluidized.
[0252] In some exemplary embodiments of the invention, the mixture of tahini and water (with or without rice bran extract) is cooled to aid in formation and/or stabilization of an emulsion.
Exemplary Rice Bbran Extract
[0253] In some embodiments, rice bran extract (RBE) is added to prepared tahini or other finely ground oily seed suspensions containing water prior to spray drying. One example of rice bran extract suitable for use in various exemplary embodiments of the invention is Nu-RICE/Nu-BAKE from RIBUS INC. (St. Louis; Mo., USA).
Exemplary Oily Seed Types
[0254] Microfluidization to produce homogenates and/or spray drying of the homogenates are expected to be applicable to a variety of oily seeds including, but not limited to, white sesame, red sesame, black sesame, nigella, peanuts, pistachios, almonds, Brazil nuts, macadamia nuts, hazelnuts, pecans, cashews, olives (with pits removed), sunflower seeds, corn kernels, wheat kernels, and soybeans.
[0255] According to various exemplary embodiments of the invention, these seeds are ground using only their natural oil and/or with their natural oil plus oil from another source and/or using only oil from another source (i.e. after their natural oil is extracted).
Exemplary use Scenarios
[0256] Spray-dried powder produced from homogenates of sesame seeds and/or other oily seeds is expected to find utility as a substitute for powdered milk and/or powdered eggs in a wide variety of commercial food products including, but not limited to, chocolate, cookies, candy, bread, ground meat and pasta.
[0257] Chocolate tablets and chocolate commonly include spray-dried milk powder as an ingredient. Any substitute for spray-dried milk powder should have a similar PSD (i.e. 90% <30 μm). Further decreases in particle size contribute to increased smoothness of the resultant chocolate. The PSD of spray-dried tahini suggests it is an acceptable substitute for milk powder in the preparation of chocolate (See Table 3 above). In some embodiments of the invention, chocolate is manufactured using spray-dried tahini as a substitute for powdered milk.
[0258] Alternatively or additionally, in some embodiments, spray-dried tahini is mixed with sugar(s) and/or flavorings (e.g. vanilla, cacao, nuts) to produce halva.
[0259] Alternatively or additionally, in some embodiments spray-dried tahini serves as a substitute for powdered milk in chocolate spread. Alternatively or additionally, in some embodiments, spray-dried tahini is added to nut butters (e.g. peanut butter, almond butter, chestnut paste).
[0260] Alternatively or additionally, according to various exemplary embodiments of the invention spray-dried tahini powder serves as an ingredient in prepared sport nutrition, cake frosting and/or powdered soup mix and/or seasoning mixes and/or powdered salad dressings and/or prepared salads and/or Hummus by adding Hummus powder and lemon, salt and spices and/or mayonnaise and/or mayonnaise substitutes.
Comparison to Previously Available Alternatives While there are spray dried products derived from nuts and oily seeds in the marketplace, these previously available alternatives contain only about 50% nuts/seeds. The remainder of the product is bulking agent(s) such as maltodextrin.
[0261] In sharp contrast maltodextrin and/or other bulking agents are not required in powdered products derived from nuts and oily seeds according to exemplary embodiments of the invention.
Exemplary Health Considerations
[0262] Microfluidization 110 (
Microfluidization of Crude Tahini Influences Emulsion Stability in Prepared Tahini
[0263]
[0264] Briefly 6.5 grams of microfluidized crude tahini and 6.5 grams of control crude tahini were each mixed with 4.5 grams of water to produce prepared tahini.
[0265] The two prepared tahinis were each placed in a 90° C. water bath for 4 minutes.
[0266] Samples were taken with a metal spatula, placed side by side and photographed.
[0267]
Exemplary Reduced Fat Crude Tahini
[0268] In some exemplary embodiments of the invention, the change in PSD caused by microfluidization and/or the resultant reduction in viscosity contribute to an ability to remove oil from the crude tahini to produce a reduced fat crude tahini. According to various exemplary embodiments of the invention the reduced fat crude tahini has 10%, 20%, 30% or 35% or intermediate or greater percentages less fat/oil than the crude tahini from which it is prepared. In some embodiments the reduced fat crude tahini remains liquid and can be used just like conventional (full fat/oil) crude tahini. In some exemplary embodiments of the invention, the reduced fat/oil crude tahini has sufficiently low viscosity to be amenable to use in a squeeze bottle.
[0269] This is in contrast to conventional crude tahini where oil removal contributes to a dramatic increase in viscosity which makes the reduced fat product virtually unusable.
[0270] Exemplary fat reduction methods include, but are not limited to: [0271] (A) Pressing of roasted sesame seeds to remove the desired amount of oil followed by conventional grinding (ball mill and/or millstones/Macintyre/Reifiner Conche) followed by microfluidization according to an exemplary embodiment of the invention. [0272] (B) Removal of the desired amount of oil from microfluidized crude tahini according to an exemplary embodiment of the invention by centrifugation and/or microfiltration.
[0273] The same strategy can be employed to prepare reduced fat/oil versions of other oily seed pastes (e.g. peanut butter or almond butter).
[0274] In some exemplary embodiments of the invention there is provided a method including: (a) microfluidizing crude tahini to produce microfluidized crude tahini; and (b) removing oil from the microfluidized crude tahini. In some embodiments, removing oil includes centrifuging the microfluidized crude tahini. Alternatively or additionally, in some embodiments the removing oil removes at least 10% of the oil.
[0275] In some exemplary embodiments of the invention there is provided a reduced fat/oil microfluidized crude tahini composition having a viscosity cP SC4-21 at 11 RPM of 2296 or less. Alternatively or additionally, in some exemplary embodiments of the invention there is provided a reduced fat microfluidized crude tahini composition having a viscosity cP SC4-21 at 5 RPM of 2756 or less.
