A process to coagulate wasted eggs which includes an acidification step of the liquid egg, followed by a coagulation step using a heat exchanger, such as a scraped surface heat exchanger, and optionally a drying step. The obtained coagulated egg product has useful properties and can be used as animal food. The process allows the disposal of wasted eggs generated in the poultry and related industries and the production of a valuable by-product with high protein and fat content.

An egg-based liquid mixture includes egg white and egg yolk. The total cholesterol content is reduced by at least 50% with respect to the total cholesterol content of a natural egg and the caloric content is reduced by at least 40% with respect to the caloric content of a natural egg.

A raw meat protein product is prepared by a process comprising directing a raw meat protein along a mixture conduit, placing steam in contact with the raw meat protein to raise the temperature of the raw meat protein to a pathogen neutralizing temperature, and maintaining that temperature in the raw meat protein for a treatment period of time. The process then includes applying a vacuum to the heated raw meat protein to vaporize water that has condensed from the steam and then separating the raw meat protein from the vaporized water and any remaining steam.

An article includes a mixture release component defining a mixture release volume and also includes a heated mixture located within the mixture release volume. The heated mixture includes undenatured meat protein and water condensed from steam. A mixture release opening is included at an outlet end of the mixture release volume and this mixture release opening defines a passage from the mixture release volume to a vacuum chamber volume defined by a vacuum chamber. A vacuum is applied to the vacuum chamber volume. The steam from which the water has condensed comprises steam that has been placed in direct contact with a stream of undenatured meat protein in a direct steam injector having a mixture outlet operatively connected to the mixture release component.

The invention relates to a liquid egg white, with novel organoleptic and texture and/or rheological characteristics. It also relates to the methods to produce it and to compositions and food products comprising it.

Soft cooked egg products having a runny yolk are prepared by removing the eggs from their shells; cooking so that the egg white has a temperature of no more than about 175° F. and the egg yolk has a temperature of no more than about 150° F.; cooling the egg to an internal temperature of 75° F. or less; sealing the egg in a package; and pasteurizing. Alternatively the shell-less eggs are packaged sealed in a package and cooked so that the egg white has a temperature of no more than about 175° F. and the egg yolk has an internal temperature of no more than about 150° F. The processes are carried out under processing conditions such that the pasteurized, cooked, packaged eggs have runny yolks. Products made by this process are also described.

A nutritional or dietary egg supplement or food product is provided that may be eaten by children or adults. The food product is made solely of whole hen's eggs or egg whites that have been heat treated to selectively denature allergenic proteins s compared to a natural hen's egg.

A heating medium injector includes an injector structure defining a heating medium flow path and a product flow path. The heating medium flow path extends to a contact location, while the product flow path also extends to the contact location. The contact location comprises a location at which the heating medium flow path and product flow path merge within the injector. In a region along the product flow path, the product flow path is defined between a first flow surface and a second flow surface. The first flow surface comprises a surface of a boundary wall separating the heating medium flow path from the product flow path and the second flow surface comprises a surface of an opposing second boundary wall. The second flow surface is in substantial thermal communication with a second flow surface cooling structure.

A system includes a vacuum chamber, a vacuum source, and a mixture flow path adapted to be connected to receive the output of a direct steam injector. The vacuum source is operatively connected to a vacuum port of the vacuum chamber, while a product outlet port from the vacuum chamber is adapted to be connected to an arrangement for removing treated product from the vacuum chamber. The mixture flow path includes a flow path segment outside of the vacuum chamber volume and a flow path segment within the vacuum chamber volume. At least some of a surface defining the flow path segment within the vacuum chamber is in substantial thermal communication with one or more cooling structures.

A heating medium injector includes an injector structure defining a heating medium flow path and a product flow path. The heating medium flow path extends to a contact location, while the product flow path also extends to the contact location. The contact location comprises a location at which the heating medium flow path and product flow path merge within the injector. In a region along the product flow path, the product flow path is defined between a first flow surface and a second flow surface. The first flow surface comprises a surface of a boundary wall separating the heating medium flow path from the product flow path and the second flow surface comprises a surface of an opposing second boundary wall. The second flow surface is in substantial thermal communication with a second flow surface cooling structure.
