In order to overcome problems that earlier apparatus, systems and methods have experienced, an apparatus (10, 100) for treating a flowable food product (26 85), in particular being a substance selected from liquid comestibles, sauces, and liquid marinates, is proposed, said apparatus (10, 100) comprising:- a container (14, 114) constructed from a first material selected from the group consisting of polytetrafluoroethylene (PTFE), plastic, and PTFE and plastic, in particular further comprising stainless steel- an injection chamber (18, 118) arranged within the container (14, 114), and including an inlet (20, 220) and an outlet (22, 222) in fluid communication with the injection chamber (18, 118) and- at least one nozzle (42, 142) constructed from a second material selected from the group consisting of PTFE, plastic, and PTFE and plastic, the at least one nozzle (42, 142) including-- a first end in fluid communication with a source of cryogen (28), in particular being a substance selected from the group consisting of liquid nitrogen (LIN), gaseous nitrogen (N2), liquid carbon dioxide (CO2), and gaseous carbon dioxide (CO2), and-- a second end in fluid communication with the injection chamber (18, 118) for providing the cryogen (28) to the injection chamber (18, 118).A related system (12 71) and a related method for treating a flowable food product (26 85) are also proposed.
