Disclosed are methods for killing or reducing the incidence of pathogenic bacteria, comprising contacting the bacteria with a PURAC CL 21/80 solution (1-2.5% by weight) comprising lactic acid in an amount ranging from about 0.43% to 1.23% by weight and citric acid in an amount ranging from about 0.29% to about 0.88% by weight. In some aspects, the pathogenic bacteria can be present on a meat product.

The present invention relates to an improved meat tenderizing and cooking device for domestic use for the item to be thoroughly cooked from inside and outside. The invention has a fluid reservoir that will be transmitted to inner-parts of the food to be cooked through needles once pressed.

A needle cleaning system that backflushes an inner passage of needles (40) successively with a cleaning solution, such as caustic soda, pressurized air and a washing liquid. The needle cleaning machine has an airtight container (17) closed at the top by a support base (15) with holes (16) where a group of needles (40) are inserted in a position in which an upper portion of the needles, where an inlet opening is located, is outside the airtight container and a lower portion of the needles, where outlet ports are located, is inside the airtight container (17). The container (17) is connected to ducts (19, 21, 23, 25, 27) provided with valves (20, 24, 26, 28) by which the cleaning solution driven by a pump (29), the pressurized air (23) and the washing liquid (25) are supplied to the containers (17).

An automatic injection control device injects fluid at a rate directly related to the displacement rate of the device body from a held positioning member. The device has a syringe end, a gripping end, a syringe barrel coupled to the body and a refillable reservoir and at least one directional valve at the syringe end of the body. The directional valves permitting refilling of the refillable reservoir without removing the syringe barrel. Also, a transmission system is coupled to the body, as well as the positioning member, a syringe plunging member, and a gearing mechanism linking the positioning member to the syringe plunging member. The device is designed so that when the positioning member is held in a fixed extended position and the body is pulled by the gripping end, the transmission system provides a one-way motion of the syringe plunging member to precisely inject fluid from the device.

Systems and methods for providing food intervention, pumping up, and tenderization are discussed. While such systems can include any suitable component, in some cases, they include a needleless spray nozzle head that injects injectate into food without requiring the head to contact the food. In some cases, the head comprises an elongated needleless spray bar that defines multiple internal fluid channels that extend from a first end to a second end of the spray bar. In some cases, the head comprises a manifold system with a first manifold portion at the first end and a second manifold portion at the second end of the spray bar. In some cases, the first manifold portion directs the injectate towards the second end, and the second manifold portion directs the injectate towards the first end of the elongated needleless spray bar. Other implementations are described.
