Abstract:
1. A process for controlling ascorbate concentration of fresh produce treatment comprising: providing a fresh produce treatment comprised of water and ascorbate; measuring via a refractometer, a first ascorbate concentration, derived via a refractive index, in a first sample comprised of the fresh produce treatment; measuring via an electrical conductivity sensor, a second ascorbate concentration in at least one of: the first sample comprised of the fresh produce treatment and a second sample comprised of the fresh produce treatment; generating a measured ascorbate concentration based on the first measured ascorbate concentration and the second measured ascorbate concentration; comparing the measured ascorbate concentration with a control set point value to generate a difference value; and if the difference value is above a threshold, then feeding ascorbate into the fresh produce treatment.
