Abstract This work explores the use of ultrasound (US) as a means intensifying impregnation apple cubes with vitamin B 12 (cyanocobalamin). The effect different US power densities (90 and 200 WL −1 ) treatment times (5, 10, 15 min) was evaluated, on load, stability, physicochemical microstructural properties fruit matrix. enhanced producing high cyanocobalamin content products (0.12–0.19 mg vitamin/g db.). Vitamin losses in sonication medium due to application were not significant. Impregnated samples exhibited higher moisture lower soluble solids respect untreated fruit. Changes chromatic coordinates well correlated uptake. Only at highest intensities (200 , marked softening observed, which agreed changes observed tissues. Results permit US-assisted be considered promising technology preparation fortified cubes.
