Definitions

  • This patent relates to high and intermediate protein textured extruded products from food-grade biomaterials with brans and plant fibers as dispersed phase fillers for application as food substitutes in food service-prepared, processed or manufactured foods in the forms of extenders, fillers, and analogs.
  • the physical characteristics of the extrudates with brans and plant fibers as dispersed phase fillers define the various food applications of the extruded products in cooked or processed meat, vegetable, fruit, fish and fishery recipes and products.
  • the changes in physical structures of the extrudates with the addition of brans and plant fibers influence variations in length, diameter, radial expansion, porosity parameters, bulk density, hydration yield, and fiber characteristics of the extruded food-grade biomaterials.
  • extrudate is the resulting processed product of extrusion processing that is essentially based on the conversion of carbohydrates and protein biomaterials to well-defined structured textured materials.
  • the extruder hardware can convey, compress, melt, and plasticize biomaterials (van Zuilichem, 1992;
  • extrudate oscicki, 2011
  • extruder barrel a textured product of defined expansion and density.
  • the structure forming components of an extrudate are carbohydrates and proteins. These two ingredients represent the major bulk of components in an extrudate recipe.
  • the common protein ingredients for extrusion may include soy, wheat, and other high- protein legume-based proteins.
  • carbohydrates used in extrusion processing are starches and flours from cereals, tubers, and roots. Elevated temperatures and shear with limited water melt starches during extrusion (Wang, 1993; Qu and Wang, 1994; Hoover, 2001) while further increase in moisture content may effect gelatinization of starch during extrusion (Lawton et al., 1972; Chiang and Johnson, 1977; Mercier, 1980; Guy and Home, 1988; Wang et al., 1991; Mitchell and Areas, 1992; Parker and Ring, 2001). Carbohydrate conversion is also affected by the presence of other components, such as proteins.
  • starch- protein complexes help define the textural quality of the resulting extrudates that would be developed in any viscoelastic melt (Madeka and Kokini, 1992; Mitchell and Areas, 1992; Li and Lee, 1996;).
  • the carbohydrate matrix may form a discontinuous phase interacting with the more continuous fibrous phase of the proteins (Tolstoguzov, 1993; Tolstoguzov et al., 1985).
  • extrusion processing allows the development of biphasic matrices in the melt.
  • the carbohydrate matrix may consist of mixture of gelatinized starch and mostly melted starch components that may have been mechanically and thermally degraded in the extruder (Donovan, 1979; Wang et al., 1991).
  • extrudate swell variably (Padmanabhan and Bhattacharya, 1989; Chang, 1992; Housiadas and Tsamopoulos, 2000).
  • the die swell phenomenon has been reported to manifest the following: superheated water is released from exiting melt (Harper, 1981), loss of moisture increases the viscosity of the melt (Chang, 1992; Delia Valle et al., 1997), and there is the instantaneous expansion of melt as it exits the die followed by setting into a glassy state during of the cooling direct expanded products (Park, 1976; Guy, 2001).
  • Expanded extrudate can be considered a form of cellular solid forming honeycombed structures (Moscicki, 2011). These structural formations have a plurality of openings and passages of desired sizes or shapes (Bagley, 1974) with cell walls defining the boundaries of each pore.
  • Honeycombed structures of extrudates comprise of interconnected pores. Porosity, which is a significant criterion for hydration capacity (Zhang and Hoseney, 1998) and textural characteristics of extrudates, indicates the volume fraction of void spaces or air spaces inside a cellular solid material like the expanded extrudate (Lukkassen and Meidell, 2008). Void cell structures of an expanded extrudate seem to be directly related to the number of bubbles nucleated in a melt (Lue et al., 1990). The bubble nucleation phenomenon in plant polymer extrusion includes the formation of small, thermodynamically unstable gaseous embryos within the viscoelastic melt.
  • nucleus This gaseous embryo reaches critical size and grows spontaneously into a stable and permanent bubble called nucleus (Cisneros, 1999). Nucleation sites in expanding viscoelastic melt may be seeded by insoluble materials that do not transform during extrusion (Hooseney et al., 1992; Cisneros and Kokini, 2002a,b; Kokini and Moraru, 2003) like the dispersed phase fillers.
  • extruded textured food biomaterials are traditionally derived from plant-based sources of carbohydrates and proteins.
  • the traditional use of extrudate as an ingredient in processed meat is 3-tiered: extender, filler, and analog.
  • High protein-based extruded materials can either function as a meat extender or a meat analog since it would have the fibrosity, appearance, and mouthfeel of meat products.
  • extender When used to extend expensive meat materials, it is added in combination with the meat ingredients to lower down the cost of a prepared and processed meat formulation (Harper, 1981; Heinz and Hautzinger, 2007).
  • extrudates are used as an analog, all meat materials are substituted with plant-based extrudates.
  • extrudates When used as extender or analog, extrudates should closely resemble real meat in physical form and mouth feel (Sheard, et al., 1984; Rareunrom et al., 2008). When extrudates are less protein-rich and consist more of carbohydrates, these extrudates can be used as fillers (Heinz and Hautzinger, 2007). The function of extrudates as fillers does not necessitate the presence of meat-like characteristics since the extrudates are eventually used in highly homogenized food systems like meat emulsions or doughs. As bulking agents, extrudates can be at the same rank as starches and flours in food systems to provide volume (Heinz and Hautzinger, 2007). However, textured fillers have the additional benefit of providing more stable rheology than the bulking powders.
  • Dispersed phase filler An ingredient of the extrusion formulation that is often considered as minor ingredient is the dispersed phase filler. These are materials which relatively hard to solubilize in water. Dispersed fillers may constitute aggregates of proteins that are denatured and deformed or some fibrous material added to extrusion formulae such as cellulose or bran (Guy, 2001). These fillers are cited to be firm, and stable ingredients that are not necessarily reduced in its size during extrusion (Lawton et al., 1985). Filler ingredients can affect the expansion of extrudate by influencing the die swell.
  • the die swell and the elastic recoil of the elastic melt as it exits the orifice of the die is attributed to the innate elasticity of the major biomaterials of the melt (Moraru and Kokini, 2003).
  • the elastic energy of the melt is released as it leaves the die and causes the expansion towards the direction of flow of the melt (Guy, 2001).
  • the presence of dispersed phase fillers may help deform the elasticity of melt.
  • This invention details the contribution of dispersed phase fillers including brans and plant fibers that are used in formulations intended for extrusion.
  • the extrudate specific physical criteria in this invention used for the evaluation of dispersed phase filler contribution in extruded products are length, diameter, radial expansion, bulk density, hydration yield, porosity, and fiber characteristics. These parameters will be used to explain the significant function of dispersed phase materials in texturized extruded food grade biomaterials.
