Effect of postharvest treatments on Amaranthus betacyanin degradation evaluated by visible/near-infrared spectroscopy.

A visible/near-infrared spectrophotometric method was developed for prediction of betacyanin and moisture content in Amaranthus samples. This method aimed to enhance future commercial Amaranthus pigment production. The method was suitable for fast and accurate prediction of betacyanin and moisture content of Amaranhus samples. The effect of different postharvest treatments on Amaranthus betacyanin degradation was successfully investigated. Freeze-drying and -18 deg C storage could effectively restrict pigment degradation. Natural air-drying and solar drying resulted in most pigment degradation. Although degrading more pigment, fast-drying in an air oven (70 to 80 deg C) within a short time resulted in high pigment retention, and it was also easy, fast and low-cost treatment.
