Abstract:
1. A system for controlling ascorbate concentration in a fresh produce treatment comprising: the fresh produce treatment comprised of water, and ascorbate ions; a prism sensor to measure refractive index in the fresh produce treatment; a circuit to measure electrical conductivity of the fresh produce treatment; a calcium ion-specific electrode; and a controller comprising a processor, a converter, and a non-transitory readable medium having instructions therein, wherein the converter: (1) reads a concentration output from the prism sensor, (2) reads an output from an electrical conductivity circuit, and reads an output from a calcium specific electrode, and wherein the controller transmits ascorbate feed commands to a feed pump in response to a determined concentration difference value between a determined ascorbate concentration percentage and a target concentration percentage.
