Izakhiwo zokuphulukisa ze-cornel ziyaziwa isikhathi eside futhi zisetshenziselwa imithi yendabuko ngezindlela ezihlukahlukene. Umuthi we-cornelian awukwazi ukuphulukisa nje kuphela, kodwa futhi uyiphunga, uma kuwubuhle obuqhumayo noma i-compote enomsoco ocebile. Ukwakhiwa kwamakhemikhali kanye ne-caloric value cornel I-cornel izithelo ziqukethe amavithamini (C, PP, A) ushukela (sucrose, glucose, fructose), i-pectin, i-carotenoids, i-tanins, i-tannins, i-pigment coloring (anthocyanins), i-acids (i-citric, i-malic, i-tartaric, amber), i-phenolcarboxylic acid (gallic, glyoxalic, salicylic), ama-macronutrients (i-potassium, i-calcium, i-magnesium, i-sodium, i-phosphorus), i-microelements (i-iron, i-zinc, i-manganese, i-iodine), amafutha abalulekile, ama-phytoncides, ama-catechins.
