Quince

ByОлена Коновалова
QUINCE
     The fruits of the quince (Cydonia oblonga) possess a high concentration of ascorbic acid (21.0% of the Daily Value [DV] per 100 g) and choline (vitamin B4) (17.0%). The mineral profile is characterized by a significant concentration of multiple elements: boron (249.0% DV per 100 g), rubidium (55.0%), vanadium (50.0%), chromium (39.0%), cobalt (33.0%), strontium (21.4%), silicon (18.0%), iron (17.0%), copper (16.0%), and iodine (10.0%).
     The nutritional matrix includes a substantial mono- and disaccharide fraction (15.2% DV), within which glucose serves as the primary sugar (21.4% DV). Furthermore, the fruit contains galactose (74.3% DV) and is rich in dietary fiber (18.0%). Quince fruits contain starch (2.0 g per 100 g) and minor quantities of sucrose (0.64 g).
     The total purine base content per 100 g constitutes 5.0% of the daily allowance.
     It should be noted that quince fruits exhibit a capacity for the bioaccumulation of the toxic trace element strontium, containing 21.4% of its maximum daily allowance per 100 g.
