摘要:
A fruit product containing a readily oxidizable polyunsaturated fatty acid, such as omega-3 fatty acids, may be prepared by cooking a fruit base composition to obtain a cooked fruit base composition, cooling the cooked fruit base composition, admixing the fruit base composition with an oil which contains at least one readily oxidizable polyunsaturated fatty acid. Additionally, an acidic antioxidant for preventing oxidation of the at least one polyunsaturated fatty acid; and at least one polyol for providing mobility for the acidic antioxidant is admixed with the cooked fruit base composition to obtain an at least substantially homogeneous mixture, which may be formed into pieces.

A liquid encapsulant component which contains an active, sensitive encapsulant, such as a live microorganism or an enzyme dissolved or dispersed in a liquid plasticizer is admixed with a plasticizable matrix material. The matrix material is plasticizable by the liquid plasticizer and the encapsulation of the active encapsulant is accomplished at a low temperature and under low shear conditions. The active component is encapsulated and/or embedded in the plasticizable matrix component or material in a continuous process to produce discrete, solid particles. The liquid content of the liquid encapsulant component provides substantially all or completely all of the liquid plasticizer needed to plasticize the matrix component to obtain a formable, extrudable, cuttable, mixture or dough. Removal of liquid plasticizer prior to extrusion is not needed to adjust the viscosity of the mixture for formability. Release of an active component from the matrix may be delayed or controlled over time so that the active component is delivered when and where it is needed to perform its intended function. Controlled release, discrete, solid particles which contain an encapsulated and/or embedded component such as a heat sensitive or readily oxidizable pharmaceutically, biologically, or nutritionally active component are continuously produced without substantial destruction of the matrix material or encapsulant.

The present invention relates to a filled, elongate half product which can be expanded (i.e., puffed) when subjected to microwaves. The half product comprises an elongate outer casing formed from a dough containing a cereal material, water, and, optionally, starch, microwave absorptive materials (e.g., sugar or salts), and emulsifiers. Within the outer casing is a filling formed from an edible oil and flavoring. The half product of the present invention is prepared by mixing the ingredients which form the dough, cooking the dough at an elevated temperature and pressure to gelatinize the starch, venting the cooked dough to reduce its moisture content and temperature, cooling the cooked dough, coextruding the cooked dough and filling material to form a filled half product, and cutting the resulting extrudate cross-sectionally. In one preferred version of the present invention, a longitudinal slice is cut through the casing as it is extruded but prior to cross-sectional cutting to permit the half product to curl open as it puffs during microwaving. The mixing, cooking, venting, and cooling steps are conducted in a co-rotating twin screw extruder.
摘要:
An extruder operating to continuously mix, at least partially bake and extrude a preselected formulation of ingredients to provide an at least partially baked output product which, upon final baking, exhibits a cookie-like crumb structure with structural integrity. The extruder includes an added water inlet port downstream from a feed port means. A screw-type element is rotatably arranged in the extruder to vigorously mix and convey at least certain ingredients of the preselected formulation, including flour and oil, input through the feed port means, wherein the total water content, by weight, of the ingredients is less than a preselected amount. A temperature control means operates to heat treat the ingredients upstream from the added water inlet port during the vigorous mixing and conveyance by the screw-type element. A source of water is coupled to the added water inlet port to add a preselected amount of water to the ingredients to increase the water content and modify the consistency of the ingredients after heat treatment and vigorous mixing and conveying. The screw-type element downstream from the added water inlet port is arranged for a gentle mixing and conveyance of the ingredients and added water. In addition, a microwave device is coupled to the downstream end of the extruder to leaven, brown and final bake the output product.
摘要:
Inhibition of expansion of a cereal product, such as a ready-to-eat cereal, by a particulate insoluble component such as fiber and/or calcium is avoided by pelletizing the particulate insoluble component. A binder component, such as gelatinized starch, is used to bind particles of the particulate insoluble component into a coherent mass which is formed into non-expanded pellets for fortification of the cereal product. The expanded cereal products, such as extruded puffed RTE cereals which contain the pellets, exhibit a crisp, uniform texture and cell structure, improved, prolonged bowl life, a non-gritty mouthfeel, and a smooth, uniform surface appearance even though they are fortified with high amounts of the solid or particulate insoluble nutritional components.

A stabilized emulsion is mixed with plasticizable matrix material to produce shelf stable, controlled release, discrete, solid particles or pellets which contain an encapsulated and/or embedded component, such as a readily oxidizable component, such as omega-3 fatty acids. An oil encapsulant component which contains an active, sensitive encapsulant, dissolved and/or dispersed in an oil is admixed with an aqueous component and a film-forming component, such as a protein, to form an emulsion. The emulsion is admixed with a matrix material for obtaining a formable mixture or dough. An acidic antioxidant for prevention of oxidation of the active, sensitive encapsulant, and a plasticizer which solubilizes the acidic antioxidant are included in the matrix material which encapsulates film-coated oil droplets containing the readily oxidizable component. The plasticizer, such as glycerol, provides mobility for the acidic antioxidant within the matrix material of the pellets for reaction with any ambient oxygen and malodorous amines.
摘要:
Encapsulated polyunsaturated fatty acids which can be incorporated into a baked good dough or batter without smearing or dissolution of the encapsulated product contains film-coated oil droplets encapsulated by a matrix material, a liquid plasticizer which plasticizes the matrix material, and an acidic antioxidant dispersed throughout the plasticized matrix material which helps to prevent oxidation of the polyunsaturated fatty acids; and the production of a fishy taint or malodors and mal-flavors. The matrix material includes a starch component which helps to avoid a rubbery consistency and texture and promotes extrudability, and a protein component, which hardens the encapsulated product and prevents substantial smearing and dissolution during dough or batter mixing and baking. The matrix material protein content is from about 25% to about 77.5% by weight of the matrix material. The protein content of the encapsulated product is from about 15% to about 65% by weight, of the encapsulated product.
摘要:
A stabilized emulsion is employed to produce shelf stable, controlled release, discrete, solid particles or pellets which contain an encapsulated and/or embedded component, such as a readily oxidizable component, such as omega-3 fatty acids. An oil encapsulant component which contains an active, sensitive encapsulant, dissolved and/or dispersed in an oil is admixed with an aqueous component and a film-forming component to form an emulsion. An antioxidant for prevention of oxidation of the active, sensitive encapsulant, and a film-softening component or plasticizer for the film-forming component may be included in the emulsion. The emulsion is stabilized by subjecting it to homogenization. The pellets are produced by first reducing the water content of the stabilized emulsion so that the film-forming component forms a film around the oil droplets and encapsulates the encapsulant. In embodiments of the invention, the water content of the homogenized emulsion may be reduced by spray-drying to produce a powder. In other embodiments of the invention, after homogenization, the water content of the emulsion may be reduced by admixing the emulsion with at least one matrix material to thereby encapsulate the film-coated oil droplets within the matrix material. After the water content of the emulsion is reduced, a protective coating is applied on the film-coated oil droplets to obtain pellets.
