Provided herein are spread compositions having reduced levels of saturated and trans fatty acids as compared to the traditional spread compositions. The compositions provided herein comprise a seeding agent, a cellulose fiber, water, and a base oil. Also provided are methods of preparing such compositions and uses thereof.
Recent trends in the field of spread products have been directed to the development of reduced trans fat and reduced saturated fat products which also possess the desired functional properties, including the texture and spreadability. While reduced trans fat and reduced saturated fat spreads are desirable, it has been observed that spreads having less than about 40% fat suffer from severe emulsion instability after prolonged storage at refrigerator temperature. Pools of oil and moisture are observed in such products and it is believed that the fat of the products recrystallize upon storage causing the emulsion instability problem.
To address this problem, in part, substantial work has been carried out with bulking agents such as powdered and microcrystalline cellulose in the spread products. However, reducing the trans fats and saturated fats adversely affect the organoleptic properties of the products and create undesirable mouthcoating or drying sensation.
There is a continuing need for spread compositions having reduced levels of saturated fats and trans fats, and acceptable mouthfeel and physical properties for handling and food preparation.
In certain embodiments, provided herein are spread compositions with reduced levels of both trans fatty acids and saturated fatty acids, wherein the compositions comprise a seeding agent, a cellulose fiber, a base oil and an aqueous phase.
In certain embodiments, the spread compositions provided herein comprise about 40-65% aqueous phase, 1-25% seeding agent, 1-15% cellulose fiber, and 10-40% base oil based on the total weight of the composition. In certain embodiments, the spread compositions provided herein comprise about 40-60% water, 3-19% seeding agent, 3-10% cellulose fiber, and 15-19% base oil based on the total weight of the composition.
The seeding agent used herein is a blend of a diacylglyceride (DAG), a monoacylglyceride (MAG), and a triacylglyceride (TAG). In certain embodiments, the seeding agent comprises about 15-55% DAG, 4-15% MAG and 30-80% TAG based on the total weight of the seeding agent.
In certain embodiments, the base oil used herein comprises triglycerides, fatty acids and fatty acid derivatives of natural or synthetic origin, including, but not limited to high oleic canola, soybean, palm, corn, sunflower, coconut oil, rapeseed, peanut, safflower, high oleic safflower oil, olive, cottonseed, or a mixture thereof.
In another embodiment, provided herein is a method for preparing the spread compositions described herein. In certain embodiments, the method comprises mixing the base oil and seeding agent to obtain an oil mixture, adding cellulose to the oil mixture to obtain an oil-cellulose mixture, adding water to the oil-cellulose mixture followed by shearing and cooling to provide the spread composition. The order of adding the ingredients can be changed as required by a particular process. In certain embodiments, cooling is carried out with agitation.
In certain embodiments, the spread compositions so produced have lower levels of saturated fats than the margarine compositions known in the art. In certain embodiment, the compositions provided herein are used in bakery products, e.g., cookies, cakes, pie crusts, breads, icings and other products in place of conventional margarine spreads.
It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive.
Provided herein are spread compositions comprising a seeding agent, a cellulose fiber, water, and a base oil. Further provided are methods of making the compositions and uses of the compositions. The methods and compositions are described in detail in the sections below.

The cellulose fiber used in the examples is CREAFIBE QC 40.
The desired amounts of all oil phase ingredients, except cellulose, were weighed and mixed in a beaker. The desired amounts of aqueous phase ingredients were weighed and mixed in a separate beaker. Both the oil and aqueous phases were heated up to about 60° C.-70° C. The desired amount of cellulosic fibrous material was added to the fully melted oil phase ingredients being held at 60° C.-70° C. The mixture was stirred via a magnetic stirrer for about 2-4 minutes. The aqueous phase was added to the oil phase and stirred for another 2-4 minutes. The mixture containing oil and aqueous phases was poured into a stainless steel beaker and sheared at 4600-5100 rpm for 1-2 minutes.
The mixture was poured into frozen CUISINART® ICE 21 Ice Cream Maker frozen bowl and churned for 5-15 minutes. Sample were scooped out of bowl and placed in glass jars and allowed to stay at ambient temperature for 24 hours prior to evaluation of any oiling/watering out and spreadability.
1In Example 1, the oil phase also contained distilled mono and diglycerides (0.29%), soybean lecithin (0.20%), vitamin A palmitate (0.0028%), beta-carotene (0.0020%). The aqueous phase contained sodium benzoate (0.100%) and lactic acid (0.05%).
2In Example 2, the oil phase also contained distilled mono and diglycerides (0.29%), soybean lecithin (0.50%), vitamin A palmitate (0.0028%), beta-carotene (0.0020%). The aqueous phase contained sodium benzoate (0.100%) and lactic acid (0.05%).
3 In Examples 35 and 36, the aqueous phase additionally contained sodium benzoate (0.10%) and lactic acid (0.05%).
The seeding agent used in the compositions of Examples 1-37 described in Table 1 was prepared using the following general procedure. The starting raw material used in this particular example was palm oil. Other oils, including, but not limited to palm stearine, behenic FFA, soybean oil, canola oil, hear oil and FFA blends can be used in a similar reaction.
A 3-neck glass reaction vessel was charged with the starting raw material. The oil was heated to a temperature of 140° C. About 4% by weight glycerin was added and heating was continued till the temperature reached 165° C. The reaction mixture was continuously sparged with nitrogen and agitated at approximately 450-600 rpm throughout the reaction, neutralization and post-treatment process.
About 0.2% by weight CaOH powder was added at 165° C. and reaction continued for 90 minutes within a temperature range of 165° C.-175° C. The mixture was cooled to 125° C.-130° C. and about 0.375% by weight of 85% conc. phosphoric acid was added to neutralize. Mixing was continued for 10 minutes. About 0.5% by weight each of trisyl and filter aid were added; mixing was continued for 10 minutes. The product was recovered by filtration, and filtered material was then deodorized for 4 hours at 226°-232° C. and 0.114-0.870 mbar.
A spread composition similar to the composition of Example 35 was prepared using a blend of commercial TAGs, DAGs and MAGs instead of the seeding agent described in Example 37. The blend of commercial esters was prepared with: 52% Fully hydrogenated palm, 42% TRANCENDIM® and 6% BFPO 65 Palm. The spread composition was prepared using the general procedure as described above for Examples 1-37, and allowed to sit for 24 hours before evaluation.
A comparison of the compositions of Example 35 and 39 indicated that the composition of Example 39 was softer in comparison to compositions made with the seeding agent (Example 35) and had a texture that tended to spread yet lump. The composition with the seeding agent (Example 35) had a smoother creamier texture and appearance.
The following compositions were prepared in a pilot plant on a 10 pound scale using a procedure described for Example 1-35. The oil blend contained 69% palm oil, 17% palm stearin, 13% soybean oil, and 1% Estric™ (available from Bunge).
The samples which were 10 lbs mini cubes were placed into the 70° F. and 85° F. temperature control rooms in order to examine the shelf life. In both compositions no signs of oiling out were observed in the 70° F. environment after 3 months while slight oiling out was observed within the first month in the 85° F. environment. Samples were also submitted for microbial analysis. Both of the samples demonstrated microbial stability over the course of three months.
Croissants, chocolate chip cookies, and sugar cookies were prepared using the pilot plant samples and compared with those prepared using Bunge™ NH 500 Baker's margarine. The fat and saturated fat content of the baked goods are shown in Table 2 below.
The following compositions were prepared on a 5 pound scale using a procedure described for Example 1-35. The oil blend contained 69% palm oil, 17% palm stearin, 13% soybean oil, and 1% Estric™ (available from Bunge).
Cakes, brownies, croissants, and garlic toast were prepared using these samples, and compared with those prepared using Bunge™ NH 500 Baker's margarine. The fat and saturated fat content of the food products are shown in Table 3 below.
