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.
Claims11
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;
- 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 conveyed to the treatment station at a temperature below about 10° C.;
- and
- during the treatment step, an ohmic treatment assembly subjects said mixture to a potential difference of at least about 500 Volt with a frequency from about 18 KHz to about 26 KHz in an amount of time below 30 seconds so that said first ingredient, which, at the beginning of the treatment step, has a temperature below about 10° C., is pasteurized and/or sterilized.

- during the first conveying step, said first ingredient is conveyed to the treatment station at a temperature below about 10° C.;
- and
- during the treatment step, an ohmic treatment assembly subjects said mixture to a potential difference from about 500 Volt to about 5700 Volt with a frequency of up to about 26 KHz in an amount of time below 30 seconds so that said first ingredient, which, at the beginning of the treatment step, has a temperature below about 10° C., is pasteurized and/or sterilized.
