✦ Synopsis
Taste testings and saponin estimation by a simple afiosimetric method showed that quinoa containing 0.1 1 % saponins or less (corresponding to foam heights of 1.0 cm or less) can be considered sweet. A variation of the standard afiosimetric method is described which reduces total analysis time fiom 73 to 7 min. Used with the proper precautions, this rapid method, in which quinoa producing foam heights of 1.3 cm or less is considered sweet, is suitable for selecting promising low-saponin varieties in field trials and for monitoring the eficacy of abrasive dehulling (polishing) as a debittering process.
