Definitions
- the invention relates to food products comprising a novel composition of bacterial reticulated cellulose that functions, inter alia , as a food additive that imparts desirable qualities to food.
- the invention further relates to methods for using bacterial reticulated cellulose ("RC") in the preparation of consumables. More particularly, the present invention relates to the preparation of food products containing bacterial reticulated cellulose in lieu of or in addition to fat.
- RC bacterial reticulated cellulose
- celluloses including microfibrillated cellulose, microcrystalline cellulose, parenchymal cell cellulose and bacterial cellulose pellicles have also been used or proposed for use in replacing fat in reduced-fat foods (see, for example, U.S. Patent Nos.
- Cellulose comprises primary linear chains of beta- (1-4) D-glucopyranose units with an arrangement of secondary chains of beta- (1-4) D-glucose to form an aggregate molecule.
- the primary linear chains within this aggregate molecule can be arrayed in a very ordered manner, such as a parallel or an anti-parallel manner. Alternatively, the primary linear chains can be arrayed in other complex structures including random structures.
- the secondary structure chains of cellulose are known as "microfibrills" and often, also, form a tertiary structure in the aggregate molecule. Therefore, regions of varying crystalline cellulose structures can be dispersed between or among regions of amorphous cellulose. These different adjacent microfibrills form strong intermicrofibrillular associations and stabilize varying tertiary cellulose structures. Accordingly, cellulose structures such as bundles, sheets, and the like can form a tertiary structure of cellulose. This tertiary structure of cellulose is commonly known as a fibril or a fiber.
- Microfibrillated cellulose (“MFC”) is produced from a low solids liquid suspension of regular cellulose pulp.
- a slurry of pulp is heated to a temperature of, desirably, at least 80°C and passed through a commercially available APV Gaulin homogenizer that applies pressures of, preferably, between 5,000 to 8,000 pounds per square inch (psi) .
- psi pounds per square inch
- the suspension is subjected to a high velocity shearing action followed by a high velocity decelerating impact against a solid surface.
- the high velocity shearing action and decelerating impact are both caused by an instantaneous drop in pressure or "explosive decompression". This process is repeated until the slurry of pulp becomes a substantially stable suspension, converting the cellulose into microfibrillated cellulose without substantial chemical change to the cellulose starting material.
- Microcrystalline Cellulose is commercially available from the FMC Corporation under the tradename AVICELTM.
- Microreticulated microcrystalline cellulose (“MRMCC”) is produced by passage of a low solids suspension of MCC through a homogenizer (e.g., APV Rannie) at 12,000 to 13,500 psi.
- MRMCC is commercially available from the FMC Corporation under the tradename AVICELTM PH101.
- Parenchymal cell cellulose is prepared from parenchymal cell-containing products such as sugar beet pulp and citrus juice sacs.
- PCC has a tertiary structure resulting from intermeshed and relatively disordered layers of microfibrils of cellulose that displays ultra high surface area characteristics.
- Bacterial cellulose pellicle is produced via fermentation of Acetobacter under static conditions. Cellulose sub- elementary fibrils are extruded from a row of pores in the bacterial cell, forming a cellulose pellicle. Each microfibril is composed of an average of three sub-elementary fibrils which are arranged in a helix. Individual ribbons are composed of bundles of microfibrils that associate with one another by hydrogen bonding to form a tertiary structure. The width of the ribbon is less than that of conventional cellulose from plants. Bacterial cellulose pellicle is characterized by a disorganized layer of structure consisting of overlaid and intertwisted discrete cellulose fibrils. The fibrils are generally oriented with the long axis of the fibril in parallel but disorganized planes.
- RC bacterial reticulated cellulose
- a particularly advantageous feature of RC stems from the surprising discovery that, when properly processed or activated, RC provides a significantly enhanced functional contribution per unit weight relative to conventional cellulose bulking agents. When properly activated, only about one-fourth to one-half the quantity of RC, as compared to conventional cellulose ingredients is necessary to achieve functional properties in a wide range of food products. Thus, it is expected that food products may be prepared using RC that lack many of the negative organoleptic properties associated with foods prepared with higher amounts of conventional cellulosic ingredients.
- RC which is produced from the aerobic fermentation of Acetobacter under agitated conditions (U.S. Patent No. 5,079,162 and U.S. Patent No. 5,144,021, herein incorporated by reference) , is characterized by an extremely high surface area and a highly reticulated network structure as compared to other celluloses. RC is distinguished from cellulose from static bacterial cultures by having an ordered interconnected (reticulated) structure instead of the disordered overlapping structure characteristic of bacterial cellulose pellicle.
- RC is also characterized by a cellulose II component not present in bacterial cellulose pellicles cultured under static conditions (for a comprehensive review of the properties of RC, see, U.S. Patents Nos. 5,079,162 and 5,144,021).
- RC has excellent functional properties for use as a food ingredient (i.e., thickening agent, stabilizer, fat substitute, or texture or appearance enhancer, etc.) has heretofore remained unreported.
- the advantages resulting from use of activated RC are surprising. Consequently, the use of RC in the preparation of products including, but not limited to, full- fat, reduced-fat and substantially fat-free food products, has not been previously described.
- U.S. Patent No. 5,441,753 ('753 patent) describes a composition that is a composite of cellulose and a surfactant. The cellulose is coated with surfactant to reduce the chalky taste of foods prepared with cellulose.
- the '753 patent does not describe the use of RC.
- thermostable edible composition having ultra-low water activity for use in making co-extruded food products such as filled cookies similar to those sold under the tradename OREOTM.
- the composition comprises, among other agents, ultra high surface area cellulose to provide flow control and thermostable properties.
- the ultra high surface area cellulose is obtained by processing celluloses such as MFC, MCC, PCC and bacterial cellulose pellicle under high shear.
- the patent does not describe the use of RC, nor does it describe the use of processed celluloses in foods other than thermostable fillings.
- the present invention relates to food products which comprise bacterial reticulated cellulose ("RC").
- the food products of the present invention generally comprise, in addition to spices, flavorings and other ingredients, RC which has been processed to impart a functionality to the food product that is typically associated with fat or other ingredients conventionally found in foods.
- the bacterial reticulated cellulose is generally added to the food product in an amount sufficient to provide positive functional and organoleptic properties.
- These functionalities include, but are not limited to, thickening, yield stress, heat stability, suspension properties, freeze-thaw stability, flow control, foam stabilization, coating and film formation, and the like.
- the present invention is based, in part, on the surprising discovery that RC is a superior ingredient for the preparation of foods in general, and particularly foods not having the levels of fat conventionally found in such foods.
- RC can be incorporated into food products at significantly lower concentrations than conventional cellulose ingredients.
- food products incorporating RC achieve comparable or superior organoleptic properties while simultaneously reducing the negative organoleptic properties typically associated with food products prepared with higher quantities of conventional cellulose bulking agents.
- compositions comprising RC in the preparation of the above described foods, including those not having the levels of fat conventionally found in such foods.
- the methods of preparing compositions comprising RC generally involve preparing a dispersion of bacterial reticulated cellulose, activating the bacterial reticulated cellulose, and incorporating the activated bacterial reticulated cellulose into a food product.
- the RC may be added in the dispersed, unactivated state with activation occurring at some point during the food preparation process.
- bacterial cellulose displays an inherently high surface area, but it can be significantly enhanced by high-energy processing. Accordingly, methods are provided for preparing a dispersion of RC, activating the desirable functional properties of the RC dispersion by high-energy mechanical processing (i.e., with the aid of a mixer or homogenizer, etc.) , and incorporating the activated bacterial reticulated cellulose compositions, dispersions, or mixtures thereof, into a food product.
- the presently described compositions comprising activated forms of RC may be spray-dried, or otherwise desiccated, prior to use as a food ingredient.

- Bacterial Reticulated Cellulose As used herein, "bacterial reticulated cellulose” or the abbreviation “RC” refers to cellulose obtained from agitated aerobic fermentation of Acetobacter as described in U.S. Patent No. 5,079, 162.
- Bacterial Cellulose Pellicle As used herein, "bacterial cellulose pellicle” refers to cellulose obtained from static aerobic fermentation of AcetoJbacter as described in Hestrin and Schramm, 1954, Biochem. J. 58: 345-352.
- Microcrystalline Cellulose As used herein, “microcrystalline cellulose” or the abbreviation “MCC” refers to cellulose having properties similar to the colloidal grades of cellulose sold by the FMC corporation under the tradename AVICELTM.
- the present invention relates to the use of bacterial reticulated cellulose ("RC") as an ingredient of food products in which one or more of the following functionalities are desirable: thickening, yield stress, heat stability, freeze-thaw stability, flow control, foam stabilization, and coating and film formation, and the like.
- RC bacterial reticulated cellulose
- the present invention is also directed to the use of RC in reduced-fat or substantially fat-free food products.
- the presently described food products incorporate RC to impart desired functionality to the food product.
- RC can surprisingly replace some of the organoleptic characteristics of fat in many food pro ⁇ well as other functionalities typically associated with rches or other common food ingredients.
- RC Bacterial reticulated cellulose
- RC Bacterial reticulated cellulose
- U.S. Patents Nos. 5,079,162 and 5,144,021 Bacterial reticulated cellulose
- RC Bacterial reticulated cellulose
- the term "extremely high surface area RC” shall generally refer to RC having a mean surface area at least about 2-fold higher than “ultra high surface area” cellulose compositions as described in the '753 patent, preferably at least about fifty-fold higher mean surface area, and specifically at least about 100-fold higher up to about 1,000-fold higher mean surface area when activated by similar processes.
- RC generally has about a 200-fold greater surface area than microcrystalline cellulose ("MCC”) .
- MMCC microcrystalline cellulose
- RC further comprises a smaller fiber diameter than plant- derived celluloses (0.1 ⁇ m to 0.2 ⁇ m as compared to 25-30 ⁇ m) , and has a highly reticulated network conformation.
- RC has a cellulose II component not present in statically cultured bacterial cellulose pellicles (U.S. Patent No. 5,079,162) .
- the physical properties of RC make it ideally suited for use in a wide variety of food products. RC is particularly suitable as a tool in fat-reduced formulations due to its positive contributions to texture, mouthfeel and other organoleptic properties.
- RC is insoluble, and consequently stable under the conditions (i.e., pH, salt concentrations, temperatures, etc.) used to prepare a variety of foodstuffs.
- RC is thixotropic, making it ideally suited for use in food spreads, where it exhibits less resistance to shear during spreading followed by rebuilding of the desired structure when shear is removed.
- Aqueous dispersions of RC have higher viscosities than dispersions of other celluloses (at similar concentrations) , including celluloses that have been processed to have increased surface area (U.S. Patent No. 5,366,750).
- RC also exhibits significantly higher yield stress across a broad range of concentrations than other types of celluloses, which contributes to the superior stability of food products prepared with RC.
- RC also exhibits pseudoplasticity, making it ideally suited for liquid foods such as salad dressings where suspension of particulates and ease of pouring are important considerations.
- RC significantly contributes to its thickening efficiency in a variety of food applications. Quite surprisingly, it has been discovered that significantly less RC is required to achieve the desired qualities in food products as compared to products prepared with conventional cellulose ingredients. This is especially true in utilities which take advantage of RC's fat mimetic functionality. Consequently, food products, including, but not limited to, reduced-fat and substantially fat-free food products prepared with RC are contemplated to exhibit comparable fat-like functional and organoleptic properties as compared with foods prepared with conventional cellulose ingredients. Additionally, given that less RC is required, reduced-fat and substantially fat-free foods prepared with RC will generally display a corresponding reduction in the astringent and/or chalky tastes commonly associated with foods containing other types of celluloses.
- RC can be used as a fat substitute, replacement or extender, thickening agent, yield stress enhancer, stabilizer, film-former or binding agent in foods, including but not limited to, low moisture food products (including nut pastes such as peanut butter, confectionery spreads such as cookie fillings, chocolate and other compound confectionery coatings, confectionery fillings such as nougat, caramel, truffle, fudge, etc., confectionery and bakery icings and glazes, creme fillings, snack spreads and fillings, and the like) ; dairy products, milk based products or substitutes therefore (including cream substitutes, RC-stabilized forms of steamed milk or substitutes therefore, frozen snacks such as ice cream, frozen yogurt, soft-serve or hard-packed frozen desserts, ice milk, butter, margarine, sour cream, yogurt, and the like) ; salad dressings; and cream or
- RC is generally incorporated into such foods in an amount sufficient to impart positive functional and organoleptic properties substantially similar to those observed for conventional food products having a higher fat content.
- RC may be used in amounts sufficient to impart the food product with the positive textural and sensory characteristics (e.g., body, smoothness, creaminess, appearance, etc.) that are typically associated with higher- fat foods.
- the lower amount of RC required to effect the desired functional qualities will avoid, or at least significantly decrease, the negative organoleptic properties typically associated with foods containing conventional cellulose-based food additives.
- RC is typically used in sufficiently small quantities to avoid imparting an astringent or chalky flavor, lumpy texture, non-rounded mouthfeel, etc. to the food product.
- reduced-fat or substantially fat-free food products prepared with RC may have comparable or improved taste, appearance, texture, mouthfeel and stability vis-a-vis feduced-fat and fat-free foods prepared with conventional cellulose ingredients.
- This feature allows for the additional use of RC as texturizer, or a fat-substitute or fat-extender in food products where conventional cellulose food additives have failed to adequately replace some of the necessary functionalities of fat.
- the amount of RC incorporated into a food product will depend in part on the amount of fat or other ingredients in the food product, and on the particular properties of the food product, including, by way of example and not limitation, moisture content, desired texture, desired viscosity, desired stability, desired yield stress, flow properties, etc. Generally, applicants have found that less RC (as compared to conventional cellulose ingredients) is necessary to achieve comparable or superior properties. Generally, RC can be used in amounts about 5% to 90% less than, typically about 30% to about 70% less than, and more typically about 40% to about 60% less than the amount of conventional cellulose ingredients typically used for a particular food product with satisfactory results. Preferably, the quantity of RC used will be about one-fourth to one-half that of the quantity of conventional cellulose ingredients. One of ordinary skill will also appreciate that the fact that less RC is required to provide equal or better functionality in a given food product improves both the logistic and economic aspects of the food production process.
- a composition comprising RC in terms of the amount of RC used to prepare the food product, generally about 0.01% to about 5% (w/w) of a composition comprising RC may be incorporated into a food product with favorable results. About 0.05% to about 3% (w/w) is preferred, while about 0.1% to 1% (w/w) is most preferred. Levels suitable for particular applications will be apparent to those having skill in the art, especially in light of the detailed disclosure herein.
- RC will generally be used at about 0.1 to about 1.0 (% w/w), and preferably about 0.1 to about 0.5 (% w/w);

- RC will generally be used at about 0.05 to about 1.0 (% w/w), and preferably about 0.08 to about .8 (% w/w).
- substantially fat-free a food product where substantially all of the total fat typically added during preparation of a food has been replaced with a fat substitute comprising RC.
- some of the ingredients may contain fat, usually in amounts that do not appreciably contribute to the total fat content of the food.
- Food products that are substantially fat-free may contain such ingredients. Any or all of the fat conventionally found in full fat products may be replaced.
- One skilled in the art should recognize the levels which are desired to be replaced.
- reduced-fat is meant a food where some of the total fat typically added to a food during preparation thereof has been replaced with RC. Any or all of the fat conventionally found in full fat products may be replaced. One skilled in the art should recognize the levels which are desired to be replaced.
- RC may be used to prepare reduced-fat and substantially fat-free food products, it can also be used as a texturizer, stabilizer, viscosity or stress yield enhancer, etc. in foods where the conventional amount of fat is found in the product or only a small part of the fat content of the food will be replaced with RC.
- RC is to be used as an ingredient in a food product, it will generally be added as a composition comprising RC that has been treated to activate the desired functionalities.
- RC will typically be activated by mixing (using a mechanical mixer, high shear mixer, blender, or the like) an aqueous dispersion of RC.
- the RC suspension is activated by additional high energy processing or mixing.
- high energy processing or mixing include, but are not limited to, homogenization (particularly high-pressure, extrusion, or extensional homogenization (U.S. Application Ser. No. 08/479,103, filed June 7, 1995, herein incorporated by reference), sonication, and the like.
- the RC After activation, the RC is generally ready for incorporation into a food product. Alternatively, the activated RC may be stabilized for subsequent use.

- EXAMPLE PHYSICAL PROPERTIES OF RETICULATED CELLULOSE
- the following examples demonstrate the physical properties of reticulated cellulose that make it particularly suited for use in the preparation of conventional food products, reduced-fat and substantially fat-free food products.
- RC typically, in order to achieve maximal functionality, RC must be activated by high-energy processing.
- the RC compositions used in the examples described below generally comprised a spray-dried blend of RC, CMC, and sucrose at a ratio of about 6:1:3 (w/w), and the RC was activated by high shear mixing, or one or more passes through the APV Gaulin homogenizer operated at a pressure between about 2,000 and about 10,000 psi, or by passage through an extensional homogenizer at a pressure between about 500 and about 2,500 psi.
