"Depending on the plant, vegetative organ, and age of species, different amounts of boron complexing sugars (BCs) have been found [14, 22]. Most of the intake of fructoborate esters (> 90%) comes from apples, grapes, onions, and wheat. High levels of BCs (fructose and sorbitol) were measured in apple juice (4.12–6.76 and 0.11–0.51 g/100 mL, respectively) [14]."
