Definitions

  • This invention is in the field of processing and packaging soy protein products, such as soybean meal, soy flours and soy protein concentrates for human consumption.
  • U.S. Patent 4,153,738 discloses the formation of toasted soy protein flakes, obtained from steam conditioned/flaked cracked soybeans which have been deoiled (defatted) normally with the aid of an organic solvent, i.e., hexane, by texturizing said flakes in an Anderson expeller or in a similar later model screw press model employing the combination of steam/temperature and pressure, fragmenting the texturized protein, hydrating the fragments (moisture content 12 to 25%), and rolling same into a flaked shape at a temperature that will impart sufficient toasting to the flakes.
  • an organic solvent i.e., hexane
  • British Patent 588,354 discloses compression of unspecified food products.
  • a number of patents are directed to texturizing soy protein by heat and pressure, U.S. 4,057,656 (Rock); U.S. 4,103,034 (Ronai); and U.S.
  • U.S. 3,843,816 (Towba) and U.S. 3,886,298 (Hayes) disclose texturizing protein by heating and compressing followed by expansion.
  • an approach was found to creating a fabricated sponge-like material made from defatted soy protein particulates, namely, defatted soy flours and soy protein concentrates which are capable of being compressed in molded cavities to form dense unitary structures having sufficient integrity to withstand easy fragmentation during shipping and commercial handling, yet capable of ready rehydration.
  • the generation of sponge-like character is accomplished through a texturizing process. This texturizing process provides cellular structure similar to natural cellular structures.
  • soy flour 50% protein
  • soy protein concentrate 65 to 72% protein
  • soy flours and protein concentrates had to first be texturized by extruding these products in a moistened state, accomplished by admixing water to the dry material. Only after such texturization and adjusting the water content to about 10 to 20% was it possible to compress the material, applying compression pressures of 1,500 to 3,000 lbs. per square inch in a manner that resulted in a high density product which would greatly expand on rehydration.
  • This invention encompasses compressed texturized soy protein products having a protein content greater than 45%, a moisture content of about 5 to 15%, a bulk density of about 30 to 40 lbs. per cubic feet, and an expansion capacity upon rehydration of about 50 to 150%.
  • the invention also includes a method for making such compressed texturized soy protein products which includes the steps of texturizing dry powdered soy flour or protein concentrate into structured porous particles by admixing moisture and then extruding the moistened soy protein mass under elevated temperature and pressure, and finally drying same to a moisture content of about 12 to 18%; then compressing the textured particles into a cake.
  • the resulting compressed cake expands 50 to 150% of its original volume upon rehydration.
  • failure to texturize the soy protein product to compression results in a hard product which is slow to rehydrate and difficult to break into small parts
  • Texturizing soy flour or protein concentrate prior to compression results in a product which readily expands on rehydration to provide a desired texture and consistency.
  • the invention provides an edible soy protein ingredient for human consumption, such as a soy protein extender in meats, poultry and fish. It has also some usefulness in animal feeds and pet foods.
  • FIG. 1 illustrates the method for compressing texturized soy protein and packaging the compressed cake.
  • the invention encompasses compressed texturized soy protein products having a protein content greater than 45%, preferably 50 to 72%; a moisture content of about 5 to 15%, and a bulk density of about 30 to 40 lbs. per cubic feet, preferably about 35 lbs. per cubic feet.
  • the compressed texturized soy protein of the invention are characterized as being easy to handle, store and ship. They are resistant to fragmentation or flaking and rehydrate rapidly.
  • Soy flour suitable for the use in this invention is the screened, graded product obtained from defatted flakes (after the removal of the oil by expelling or extraction) derived from selected, sound, clean, dehulled soybeans, except that full-fat soy flour is not subjected to expelling or extraction and contains all of the oil originally present in the soybean; said flour is ground finely enough to pass through a 100-mesh or smaller screen and is usually available in various sizes to meet specific requirements.
  • the protein content of soy flours as a generic class is 40 to 60% (N x 6.25), as defined by the National Soy Processors Association (NSPA). According to the tentative Common and Usual Name Regulation
  • soy protein concentrate suitable for use in this invention is the product prepared from high quality, sound, clean, dehulled soybeans by removing most of the oil and water soluble non-protein constituents and shall contain not less than 65% protein (N x 6.25) on a moisture-free basis.
  • soy protein is described in Soybeans: Chemistry and Technology, Vol. I Proteins ed. by Allan K. Smith and Sidney J. Circle, The AVI Publishing Company, Inc., 1972.
  • Texturizing is preferably accomplished by mixing 15 to 50%, preferably about 30% water with the soy flour or soy protein concentrate to provide a moistened mass, and extruding same to form a extruded texturized porous composition having ample void cellular spaces capable of soaking up liquid upon rehydration.
  • This texturized composition is then preferably broken into smaller structured particles by cutting the extrudate as it emerges from the extruder and milling the cut segments through a sizing screen.
  • the moisture content of the structured particles is adjusted from 12 to 18%, preferably about 14 to 16%.
  • the structured particles are then compressed with conventional equipment at 1,500 to 3,000 lbs. per square inch.
  • FIG. 1 illustrates the method by which the texturized soy particles are compressed and packaged.
  • a rigid container (1) is placed in a depression (2) of a forming platform (3).
  • a metal insert (4) which conform to the inner walls of the container (1) is inserted into the depression.
  • the metal insert is then filled with texturized soy protein (5).
  • the texturized protein is compressed with a compression piston (6).
  • the metal insert is removed and the rigid container containing the compressed texturized soy protein cake is removed from the forming platform and sealed.
  • the texturized compressed soy protein can be advantageously compressed and packaged in boxes.
  • the package may contain 0.1 to 50 lbs. size blocks or other shapes specified by the user.
  • a Fitzmill equipped with a sizing screen having five-sixteenth inch times five-sixteenth inch holes.
  • the sized pieces were irregularly shaped, having dimensions of about one-fourth inch times three-eighth inch times one-sixteenth inch, a bulk density of about 12 lbs. per cubic feet, and a moisture content of about 24%. This material was then dried to a moisture content of about 16%, and the bulk density was about 13.5 lbs. per cubic feet. About 45 g of the material was placed into the mold cavity of a Dension Press and compressed for about three seconds at about 2,150 lbs. per square inch.
  • the resultant cake After removing from the mold, the resultant cake retained its pressed form, and did not become crumbly and break apart.
  • the density of the cake was 0.63 g/cc (39.31 lbs. per cubic feet).
  • the cake's rate of water absorption was as rapid as that of the material which was not pressed. As the cake hydrated, it expanded very quickly until its volume was about equal to the volume of an equal weight of uncompressed, hydrated material.
  • Example 2 A composition according to Example 1, except that soy flour, having a protein content of 53%, was used as the starting material. After texturizing, the product was dried to a moisture content to about 16% prior to its compression under conditions described in Example 1. The cake thus obtained retained its pressed form and showed density and rehydration characteristics similar to those observed for the cake made with soy protein concentrate.

Abstract

Produits de protéines de soja texturées comprimées ayant une teneur en protéines supérieure à 45 %, une teneur en humidité comprise entre 5 et 15 % environ, une masse volumique non tassée de 30 à 40 livres par pied cubique environ et une capacité d'expansion de 50 à 150 % environ en volume lors de la réhydratation. L'invention permet d'obtenir un produit alimentaire de rehydratation et d'expansion rapide de densité élevée qui résiste à la fragmentation dans des conditions normales de commercialisation et de transport et offre des avantages économiques lorsqu'il est stocké et transporté sur des produits existants sur le marché. L'invention concerne également un procédé de production d'un tel produit de protéine de soja texturées et comprimées, qui consiste d'abord à texturer les ingrédients de protéine de soja conventionnelle ayant une matrice cellulaire fibreuse, telles que des farines de soja et des concentrés de protéines de soja, puis à ajuster la teneur en humidité des particules structurées de ces ingrédients de protéines de soja jusqu'à un pourcentage compris entre 10% et 20 % environ, et finalement à comprimer ces particules pour obtenir un gâteau pouvant se dilater lors d'une réhydratation de 50 à 150 % de son volume d'origine.
