A food product treatment system, comprising: an injectade reservoir; a filter (20, 35); a first positive displacement pump configured to force injectade from the injectade reservoir through the filter (20, 35); a spray nozzle head, comprising multiple inlet channels and multiple sets (360, 365, 370) of nozzles, wherein the multiple inlet channels direct injectade to the multiple sets (360, 365, 370) of nozzles, and wherein the spray nozzle head is configured to receive the injectade from the first positive displacement pump, act as a manifold, deliver a consistent and predictable amount of injectade, and inject the injectade into a food product without having the spray nozzle head contact the food product; and a valve (45, 60, 120) that is configured to selectively open and close to regulate when and how much of the injectade that passes through the filter (20, 35) is forced out of the multiple sets (360, 365, 370) of nozzles, wherein the system further comprises: (a) a computer processor that is configured to control an amount of the injectade that is forced out of the multiple sets (360, 365, 370) of nozzles; and (b) a first and a second pressure sensor (42, 44, 46), wherein the first pressure sensor is configured to measure a pressure of the injectade prior to passing the valve and wherein the second pressure sensor is configured to measure a pressure of the injectade after passing the valve and before being forced from the multiple sets (360, 365, 370) of nozzles. an injectade reservoir; a filter (20, 35); a first positive displacement pump configured to force injectade from the injectade reservoir through the filter (20, 35); a spray nozzle head, comprising multiple inlet channels and multiple sets (360, 365, 370) of nozzles, wherein the multiple inlet channels direct injectade to the multiple sets (360, 365, 370) of nozzles, and wherein the spray nozzle head is configured to receive the injectade from the first positive displacement pump, act as a manifold, deliver a consistent and predictable amount of injectade, and inject the injectade into a food product without having the spray nozzle head contact the food product; and a valve (45, 60, 120) that is configured to selectively open and close to regulate when and how much of the injectade that passes through the filter (20, 35) is forced out of the multiple sets (360, 365, 370) of nozzles, wherein the system further comprises: (a) a computer processor that is configured to control an amount of the injectade that is forced out of the multiple sets (360, 365, 370) of nozzles; and (b) a first and a second pressure sensor (42, 44, 46), wherein the first pressure sensor is configured to measure a pressure of the injectade prior to passing the valve and wherein the second pressure sensor is configured to measure a pressure of the injectade after passing the valve and before being forced from the multiple sets (360, 365, 370) of nozzles.
