Techniques are described herein for improving the taste and characteristics of ground meat and foods using such, by incorporation of the composite and/or the noted composition.

Abstract: Articles produced from hydrophobic polymers (e.g., polyethylene) are surface-coated with thin films of starch in order to render the surfaces hydrophilic. The thin coatings form on the surfaces of plastic objects when the objects are placed in contact with hot, aqueous solutions of starch. These starch coatings are adherent to the hydrophobic plastic surfaces under both wet and dry conditions, and they permit the surfaces to be uniformly wet with water. The coatings may be rendered even more adherent when wet by graft polymerizing the starch with a synthetic monomer. Resultant products have the potential for improved biocompatibility, improved compatibility with hydrophilic reagents, reduced build-up of electrostatic charge, reduced blocking, reduced friction, improved absorption of water-based dyes, and improved adhesion properties. The starch coatings are non-toxic, inexpensive and biodegradable.

The thin coatings form on the surfaces of plastic objects when the objects are placed in contact with hot, aqueous solutions of starch. These starch coatings are extremely adherent to the hydrophobic plastic surfaces under both wet and dry conditions, and they permit the surfaces to be uniformly wet with water. Resultant products have improved biocompatibility, improved compatibility with hydrophilic reagents, reduced build-up of electrostatic charge, reduced blocking, reduced friction, improved absorption of water-based dyes, and improved adhesion properties.

Abstract: Polysaccharide-based shells are provided having use for forming water-dispersible microcapsular delivery systems for both hydrophilic and lipophilic drugs, pharmaceuticals, cosmetics and other active agents. These shells are prepared by intimately blending a solubilized polysaccharide with a lipophilic material to produce spherical droplets of the lipophilic material coated with the polysaccharide, diluting the emulsion with a solvent, and isolating the polysaccharide shells from the diluted emulsion.

Abstract: Lubricating additives for drilling fluids are prepared from semi-solid highly viscous and/or high molecular weight lubricants, such as polyalkylenes (e.g., polybutene), by steam jet cooking a mixture of starch, water, and the lubricant in order to uniformly suspend micrometer-sized lubricant droplets in an aqueous starch matrix. These additives avoid the need for toxic emulsifiers, surfactants, or short-chain hydrocarbon solvents for dispersing the lubricants. They impart lubricity to drilling fluids (muds) and also inhibit fluid loss in geological formations by enhancing the filtration control properties of the fluid.

Abstract: A stable and non-separable composition comprised of starch and a water-immiscible material can be prepared in the absence of external emulsifying or dispersing agents by thoroughly solubilizing an aqueous dispersion of the starch at elevated temperatures and incorporating the water-immiscible material into the non-retrograded starch under conditions of high turbulence. The resulting dispersions form soft gels that can be easily converted to pourable fluids by the application of heat. Upon drying, these dispersions yield solid compositions that are easily redispersed in water to form smooth, stable dispersions. These compositions are useful as thickening agents, suspending agents, waterproof coating materials, adhesives, fat substitutes, and seed coatings. They are receptive to the addition of a variety of other water-immiscible materials, such as volatile and essential oils, food flavorants, medicinals, waxes, agricultural chemicals, and the like.

Abstract: A stable and non-separable composition comprised of starch and oil can be prepared in the absence of external emulsifying or dispersing agents by thoroughly solubilizing an aqueous dispersion of the starch at elevated temperatures and incorporating the oil into the non-retrograded starch under conditions of high turbulence. The resulting dispersions form soft gels that can be easily converted to pourable fluids by the application of heat. Upon drying, these dispersions yield solid compositions that are easily redispersed in water to form smooth, stable dispersions that are nongreasy, yet slippery to the touch. These compositions are useful as thickening agents, suspending agents, fat substitutes, and seed coatings. They are receptive to the addition of a variety of water-immiscible materials, such as volatile and essential oils, food flavorants, medicinals, agricultural chemicals, and the like.

Abstract: Moisture-shrinkable films can be extrusion blown from flour-poly(methyl acrylate) graft copolymers. The films shrink when exposed at room temperature to relative humidities approaching 100%. The films have potential application in shrink-wrapping irregularly shaped articles without application of heat. Easy removal of the films by water washing is another feature suitable for this use. This invention allows the use of unmodified cereal flour in lieu of gelatinized starch as the substrate for graft polymerization. This substitution greatly simplifies the preparation and isolation of the graft copolymers and reduces the expense of the process by lowering raw material costs.

Abstract: Aqueous ambient temperature pastes and gels of starch and poly(ethylene-co-acrylic acid) are disclosed containing starch in an amount from about 2.5% to about 10%, by weight, of the paste or gel, and poly(ethylene-co-acrylic acid) in an amount from about 0.5% to about 20%, by weight, of the starch, the poly(ethylene-co-acrylic acid) content being sufficient to provide aqueous ambient temperature pastes having higher viscosities than the same ambient temperature pastes without poly(ethylene-co-acrylic acid) and to provide aqueous ambient temperature gels having different gel strengths from the same ambient temperature gels without poly(ethylene-co-acrylic acid). These pastes and gels are prepared by a method in which a starch and poly(ethylene-co-acrylic acid) mixture in an aqueous medium is cooked, preferably by steam-jet cooking, and the resulting starch-poly(ethylene-co-acrylic acid) solution/dispersion is cooled to ambient temperature with water retained in the solution/dispersion.
