The present invention relates to a method and an apparatus for treating foods (L; LL), such as pieces of meat, poultry, fish or cheese, by injecting an injectate, such as a brine, into a food (L; LL) as an injection item, wherein, for injecting the injectate, the injection item (L; LL) is supplied by means of a first transport device (110) to an
injection device (150) which can be reversibly lowered onto the injection item (L; LL) to be treated and, after injecting the injectate, is transported away from the
injection device (150) by means of the first transport device (110), and wherein a
weight difference is calculated from a
weight value of the injection item (L; LL) to be treated detected before supplying to the first transport device (110) and a
weight value of the treated injection item (L; LL) detected after leaving the first transport device (110). The apparatus according to the invention comprises: a first transport device (110), by means of which, for injecting the injectate, the injection item (L; LL) to be treated can be supplied to and transported away from an
injection device (150) which can be reversibly lowered onto the injection item (L; LL); a second transport device (200) for supplying the injection item (L; LL) to be treated to the first transport device (110); a third transport device (300) for transporting the treated injection item (L; LL) away from the first transport device (110); and a
control unit (180) for controlling the first, second and third transport device (110, 200, 300); wherein, in order to calculate a
weight difference, the second and third transport device (200, 300) comprise weighing apparatuses (251) for weighing the injection item (L; LL) to be treated before it is supplied to the first transport device (110) and for weighing the treated injection item (L; LL) after it has left the first transport device (110).
