Summary:
The optimum operating conditions for the recovery of saponins have been identified, within the dry debittering process of quinoa grains, by the application of a spouted bed, developed at the CIAA-CIPI.
The experimental trials were carried out with 3 ecotypes of Royal Quinoa: white, yellow and pink, at laboratory scale in a glass spouted bed reactor of 7,5 cm in diameter, which was fed with air by means of a compressor of 400 L/min provided with a filter to remove moisture and oil from the air. The effects of the following variables were evaluated: processing time, nozzle diameter, Real Quinoa ecotype and spouted bed height, in the quality of the solid waste collected (content of saponins) and in the quality of the quinoa grain (final content of saponins and loss of mass).
