Effects of high hydrostatic pressure (HHP) on bioaccessibility, as well as antioxidant activity, mineral and starch contents in Granny Smith apple

► High hydrostatic pressures promote changes in the matrix of plant cell walls. ► Antioxidant, starch and minerals were released from cell walls of the matrix plant. ► High hydrostatic pressures increase the bioaccessibility of the nutrients. ► High hydrostatic pressures treatment promotes the increase of digestible starch. ► Pressurised apple consumption may provide health benefit and prevent diseases.
