Abstract
A method for preparing a substantially pasteurized and/or sterilized food product; the method, which can be used to produce pasta sauces or soups, comprises: a cooking step, during which a base of the food product is obtained by thermally treating a first component at a temperature exceeding 30° C.; a mixing step, during which said base and a second, substantially solid component are mixed together so as to obtain a mixture; and an ohmic treatment step, during which said mixture is subjected to an ohmic treatment so as to obtain the substantially pasteurized and/or sterilized food product.
Claims20
A method of preparing a substantially pasteurized and/or sterilized food product;
- the method comprises:
- a cooking step, during which a base of the food product is obtained by thermally treating a first component at a temperature of at least about 30° C.;
- a mixing step, during which said base and a second component are mixed together so as to obtain a mixture;
- a treatment step, during which said mixture is subjected to an ohmic treatment so as to obtain the substantially pasteurized and/or sterilized food product;
- said second component comprises a first, substantially solid ingredient;
- and
- a first conveying step, during which said mixture is fed to a treatment station, where said mixture is subjected to an ohmic treatment;
- during the first conveying step, said first ingredient is at a temperature below about 10° C.
A plant for preparing a substantially pasteurized and/or sterilized food product;
- the plant comprises a cooking assembly, which is configured to prepare a base of the food product by thermally treating a first component at a temperature above about 30° C.;
- a feeding assembly for bringing said base and a second component to a mixing station;
- a mixing assembly, which is arranged in the area of the mixing station and is configured to combine said base and a second component so as to obtain a mixture;
- a first conveying assembly to bring said mixture from the mixing station to a treatment station;
- an ohmic treatment assembly, which is arranged in the area of the treatment station and is configured to subject said mixture to an ohmic treatment so as to obtain the substantially pasteurized and/or sterilized food product;
- and a second conveying assembly for conveying the substantially pasteurized and/or sterilized food product from the treatment station, to an output station;
- the second component comprising at least one first, substantially solid ingredient;
- wherein the feeding assembly comprises a first feeding device for conveying said base from the cooking assembly to the mixing station and a second feeding device for conveying the second component from a storing device to the mixing station;
- wherein the storing device is configured to keep the second component at a temperature below about −10° C.
A method for the preparation of a substantially pasteurized and/or sterilized food product;
- the method comprises:
- a treatment step, during which a component, comprising a substantially solid ingredient, is subjected to an ohmic treatment so as to obtain the substantially pasteurized and/or sterilized food product;
- at the beginning of the treatment step, said component has a temperature below about 10° C.
