  1. a Other saccharide contents were calculated from the differences between total carbohydrates and total amounts of fructose, glucose, sucrose, neokestose, kestose, nystose, and fructofuranosyl nystose
  2. b g/100 g fresh weight was calculated as a percentage of total mass of each carbohydrate in relation to total mass of peeled fresh red onions
