At present meat substitute food products are prepared, generally, from the combination of animal protein and vegetable protein. The acceptance of these products by consumers is directly related to the organoleptic qualities such as texture, taste, sensation in the mouth and appearance.
The term texture describes a wide range of physical properties of a food product. A food product of acceptable texture is usually synonymous with the quality of the product. The texture has been defined as “the attribute of a substance resulting from a combination of physical properties and which is perceived by touch, the sense of taste, sight and hearing.” The International Organization for Standardization defines the term texture as “all the theological and structural attributes (geometry and surface) of a food product that are perceived through mechanical receptors, touch and, where appropriate, through visual and auditory receptors.
The texture has received an accelerated importance in the preparation and manufacture of imitation products, meat analogues or substitutes, where very serious efforts are made to duplicate the properties of the original food substance. The use of non-traditional raw materials, synthetic flavors, fillers and stretchers all tend to alter certain textural characteristics of the finished product. Frequently, the imitation of textural properties is of much greater difficult in the replication of taste, odors, and colors. Many manipulation processes, including extrusion and texturization, have been developed to simulate properties of natural texture to give greater market acceptance of products similar to meat. It has to be taken into account that the texture-related attributes involves the appearance, the touch and the feel in the mouth, and even the interaction between the products similar to meat with the mouth, as a proper sense of mastication by the consumer, is directly related to the acceptance or not of the meat substitute product.
The microstructure of a meat substitute determines whether the substitute has a similar quality to the meat as to texture, moisture, flavor to the palate and tenderness.
At macroscopic level, some natural meat has muscle fibers that are visually perceptible; they have a cylindrical shape and are parallel. La microstructure of these fibers contains microfibrils with a diameter in the range of microns and they are also cylindrical and parallel.
The substitutes for meat products obtained by the current processes are different from natural beef in several important qualities. These products are different from meat because they lack the fiber and microfibrilar structures of meat. Their similarity with meat is only superficial and they have not been widely accepted by the public.
Examples of the current solutions to provide imitation products, meat substitutes or analogues with similar texture to an original meat product are described in the following patent documents.
Albert Spiel, in the U.S. Pat. No. 4,057,656 describes a method for preparing quick cooking foods that are tasty chewable chunks, soft, light in color and of a meat-type texture, when hydrated. The method consists of pressing the vegetable protein material containing 30% or more of protein, 5% to 10% moisture content and a nitrogen solubility index of 30 to 70 at a temperature sufficient to convert the moisture into steam. The result is that the protein material is partially or substantially soft.
Edward M. McCabe, in the Mexican patent MX-165467, describes a method for processing whole soyas to produce discrete chunks or pieces of an irregular shape of texturised proteinic material that are free of odors and flavors and have an appearance and meat-type texture. The method consists of acidifying whole soyas, grinding them in an aqueous medium to provide an aqueous suspension or a mass of soybean particles, which is passed through a pressurized steam at high temperature under the conditions that make the texturised soy protein in the form of discrete pieces or chunks. The texturised pieces are dried and rehydrated for use in a wide variety of food product. Some additives may be incorporated such as appetizers, colorings, fat, condiments and other proteinic materials, in the pieces of texturised soy protein.
Albert Monferrer Ballester, in the publication of Spanish patent application ES-2,102,974 describes a procedure for obtaining food products similar to meat or fish. The procedure is based on a mass formed by a mixture of meat or fish with ingredients and food additives such as water, salt, starch, flour, proteins, stabilizers and others, where the internal jellification is originated by combining in the mass product prepared with a soluble salt of alginic acid, a soluble calcium salt and a pH modifier.
Paul Hargarten, in the publication of the Mexican patent application MX PA04006552 describes a process for preparing a vegetable based meat analogue. Said meat analogue can be used in a variety of vegetarian foods such as fried ground beef sandwiches and stuffed meats, the procedure involves mixing methylcellulose in a mixture of water and ice to form a cream, then blending in a modified gluten a vegetable protein product that has a high solubility in water and is capable of forming a gel under a mild heat treatment, an oil to obtain an emulsion base, and a modified food starch and flavoring ingredients to form a base of a seasoned emulsion; the base of the seasoned emulsion can be stuffed in wrappings, and then be cooked; the meat imitation based on the cooked emulsion has a high resemblance to processed meat products, with improved handling properties; the addition of the meat analogue emulsion based in vegetarian food helps improve the texture, feel in the mouth and juiciness.
Matthew K. McMindes, Mitchell A. Kaestner and Michael W. Finfrock, in the publication of U.S. patent application US-2006/0035003 describe a food product based on soy protein formed by a soy protein material selected from soy protein flour, soy protein concentrate, isolate from soy protein and mixtures thereof; a humectant formed by a colorant and at least one of any of the following substances: a flavor agent, a triglyceride, an acid or acid salt of food grade, a base or base salt of food grade, and an emulsion of food grade, and water. Chunks of meat can be added to the food product based on soy protein.
Matthew K. McMindes and Eduardo Godinez, in the publication of the U.S. patent application US-2006/0035005 describe a product of restructured meat that comprises a fibrous material that contains soy protein and fiber of cotyledon soy, wherein the latter contains an amount of 1% to 8% in weight in a base free of humidity; chunks of meat and water. The preparation process consists of hydrating a fibrous material that contains soy protein and cotyledon soy fiber, adding chunks of meat with a temperature below 10° C., and mixing the fibrous material and the meat chunks to produce a product of homogeneous and texturised meat that has a moisture content of at least 50%.

Subsequently, the mixture of hydrated and colored vegetable protein is mixed with at least one meat product. The meat product may be, for example, meat chunks or minced beef, pork, turkey or chicken, giblets in chunks or chopped beef, pork, turkey or chicken, mechanically deboned meat, such as beef, pork, turkey or chicken, and mixtures thereof. The meat products together with preservatives, salt and sodium nitrite are added in a dose during mixing. This mixture is made in two stages, the first mixing stage, step 20, is performed during a period within the range of 15 to 45 minutes in a mixer with paddles with an open lid, where the paddles rotating clockwise within the range of 10 min-1 to 20 min-1, and counterclockwise each turn within the range of 2 to 10 minutes; then, a second mixing stage is started, in step 30, in a period within the range of 10 to 20 minutes and at a pressure within a range from −100 kPa to −50 kPa in the mixer with the lid closed, but with the paddles turning clockwise within the range of 20 min-1 to 40 min-1, and counterclockwise each turn within the range of 2 to 10 minutes. This two-stage mixing and dosage of the ingredients allows extracting the major amount of protein from the meat products used.
Once the hydrated and colored, vegetable protein has been mixed with the meat products, it is mixed with texturised units in order to obtain a prepared paste. This mixture is blended in three stages: the first stage of mixing, step 40, consists of mixing, during a period within the range of 5 to 20 minutes, the mixture of meat products and hydrated and colored vegetable protein with said texturised units in a mixer with the lid closed, and whose paddles rotate clockwise within the range of 10 min-1 to 20 min-1, and counterclockwise each turn within the range of 2 to 10 minutes; then proceeds to perform a second mixing stage, step 50, consisting of mixing for a period within the range of 3 to 10 minutes in the mixer with the paddles rotating clockwise within the range of 20 min-1 to 40 min-1, and counterclockwise each turn within the range of 2 to 10 minutes; then proceeds to a third mixing step, step 60, consisting of mixing under vacuum for a period from 10 to 20 and at a pressure within a range from −100 kPa to −50 kPa in the mixer, but with the paddles rotating clockwise within the range of 20 min-1 to 40 min-1, and counterclockwise each turn within the range of 2 to 10 minutes. Alternatively, during step 40, flavoring units are added in a dosed manner, which can be, for example, units with a flavor of meat, pork, turkey or chicken, and combinations thereof.
