The effect of food matrix (water-, milk-, or soymilk-fruit juice beverages) and processing [high-intensity pulsed electric fields (HIPEF); high-pressure processing (HPP); and thermal treatment (TT)] on the in vitro bioaccessibility of vitamin C and phenolic compounds, as well as on the hydrophilic antioxidant activity (HAA) of fruit juice-based beverages was analysed. HIPEF and HPP improved or did not change the bioaccessibility of vitamin C and certain phenolic compounds in comparison with untreated beverages. In contrast, TT diminished the bioaccessibility of most of these compounds. The greatest vitamin C bioaccessibility was obtained in soymilk-fruit juice beverages (SB), whereas water-fruit juice beverages (WB) favoured the bioaccessibility of phenolic compounds and HAA. Milk-fruit juice beverages (MB) reduced the bioaccessibility of these hydrophilic constituents. Results showed that both food matrix and processing modulated the bioaccessibility of vitamin C and phenolic compounds of fruit juice-based beverages. Furthermore, HPP and HIPEF allow obtaining beverages with improved nutritional and functional quality.
