Contacting Food In Liquid Or Solid State With Exteriorly Produced Gas Patents (Class 426/312)
  • Patent number: 5895676
    Abstract: A process for producing a roux-like binding agent for foodstuffs. Fine particles of farinaceous material are transported into an enclosed particle coating zone where a molten, high-melting point fat is sprayed, in the form of fine droplets, onto the particles to coat them. At the same time, the coated particles are cooled to a temperature below the melting point of the fat using chilled gas. The coated particles are flowable and disperse readily in hot water.

  • Patent number: 5871795
    Abstract: A pH increasing gas is placed under an operating pressure and in contact with the surface of a meat product to be treated. Keeping the pressurized pH increasing gas in contact with the meat product for an operating period increases the pH of the meat product at its surface. The increased pH reduces bacterial activity and helps maintain the quality of the meat product during storage. The method may also include placing a pH lowering gas at a neutralizing pressure in contact with the surface of the meat product and holding the pH lowering gas in contact with the meat product at the neutralizing pressure for a neutralizing period sufficient to bring the pH of the meat product back to a normal level. The method may further include the step of removing the treatment gas and any reaction materials either after releasing the pH increasing gas or after treating with the pH lowering gas if that step is employed.

  • Patent number: 5855941
    Abstract: Materials, for example, plant-based food products, are subjected to heat and pressure in a processing enclosure, wherein the pressure is greater than the pressure of the atmosphere. The heated, pressurized materials are then subjected to a pressure-reduction phase during which the pressure in the processing enclosure is reduced at a rate greater than 500 millibars per second and by an amplitude greater than 1 bar. The rapid pressure-reduction phase of the invention contributes to the production of processed materials having a slightly spongy structure that is due to the presence of micro-cavities that promote the recapture of subsequent moisture.

  • Patent number: 5283072
    Abstract: A blended yolk composition is disclosed comprised of a fat, an emulsifier and an aqueous component, at least one of the fat and the aqueous component containing a chicken-type flavoring. The yolk composition can be used in baking or combined with egg white, a modified egg white or a simulated egg white to produce a simulated blended whole poultry egg composition.Alternatively the yolk composition may utilize a modified yolk, such as decholesterolized yolk. Also disclosed are methods of preparing the compositions.

  • Patent number: 5281428
    Abstract: A method and apparatus for killing microorganisms on the surface of raw meat. The microorganisms are killed by exposing the meat to controlled applications of a biocidal treatment gas in a vacuum/pressure regulated environment. The meat is first exposed to a vacuum, the surface then flushed with an air-free treatment gas, then full treated with the air-free treatment gas, and then reexposed to a vacuum. The method and apparatus successfully kills microorganisms on the surface and pores of raw meat without causing significant deleterious changes to the meat.

  • Patent number: 5277922
    Abstract: A method for preserving fruits characterized by juice sacs and rag. The fruits are placed in a holding tank and submerged in a liquid having a freezing point higher than that of the fruits. The liquid may either be maintained just above its freezing point or frozen such that the temperature of the liquid is maintained above the freezing point of the fruits.

  • Patent number: 5271949
    Abstract: The present invention relates to a process for preparing a flavour concentrate, involving the steps of:(a) mildly oxidising triglyceride fat, and(b) hydrolysing the triglyceride fat to a degree of hydrolysis exceeding 10%.It was found that flavour concentrates of improved quality are obtained if prior to or simultaneously with the hydrolysis of triglyceride fat, said fat is mildly oxidised.

  • Patent number: 5250317
    Abstract: Black tea leaves are oxidized to provide treated leaves from which aqueous tea extracts which have minimal turbidity, particularly when cooled, may be obtained. The oxidation reaction is performed on black tea leaves which contain moisture only in an amount such that the oxidation reaction occurs at localized sites on and within the tea leaf structure.

  • Patent number: 5227184
    Abstract: A method for sanitizing food products that utilizes ozone containing bubbles. The food product is immersed in a liquid bath that has a plurality of ozone containing bubbles streaming therethrough. Enough ozone containing bubbles are provided such that a continuous stream of bubbles are always present within the liquid bath. The ozone containing bubbles are typically an ozone air mixture and can be introduced into the liquid bath directly as a bubble gas stream or can be mixed with the liquid of the liquid bath prior to their introduction into the bath itself. When the food product is immersed in the bath containing the ozone containing bubbles, the ozone in the bubbles contacts the surfaces of the food product and has a sanitizing effect thereon.

  • Patent number: 5208058
    Abstract: Disclosed is a novel method of treating nuts with a compressed carbon dioxide gas so as to make them oxidation-resistant. For carrying out the method, a device is used, which can contain a compressed carbon dioxide gas and which is equipped with (i) (a) door(s) or (a) gate(s) to put nuts into and take them out of itself, (ii) (a) heater(s) to heat nuts in itself, (iii) (a) chiller(s) to chill nuts in itself, and (iv) (a) valve(s) to introduce a carbon dioxide gas into itself and release the gas out of itself. Nuts as treated by the novel method with the illustrated device are to be satisfactorily oxidation-resistant when they are stored.

  • Patent number: 5147672
    Abstract: A process for the removal of sterols and/or lipid components (e.g., cholesterol and fats) from lipid containing food (e.g., meat) using sub or supercritical fluids (e.g., CO.sub.2) involves initial processing of the food to produce an intermediate moisture product in which substantially all of the "free water" but not all of the "bound water" is removed. Different moisture removal techniques may be used. Where freeze drying of food flakes is adopted the moisture level is preferable reduced to 30-55% w/w. The intermediate moisture product is treated with supercritical CO.sub.2 to remove the lipids therefrom. Optionally the cholesterol can be separated from the fat component by use of an adsorbent to selectively remove the cholesterol from the supercritical CO.sub.2. The product can be reconstituted with water and fat to provide a reconstituted meat product suitable for hamburgers.
