 Abstract Effects of pH and some chemical agents (1) on the solubilization of insoluble pectin bound to suspended particles, (2) on the viscosity decrease of native soluble pectin, (3) on the flocculation of suspended particles and (4) on the over-all clarification of apple juice have been studied Optimum pH ranges were: (1), 3.2_??_4.0; (2), 3.6_??_4.1; (3), lower than 3.0; (4), 3.2_??_3.8. Gelatin had no effect on (1) and (2) but stimulated (3) and (4). NaCl had no detectable effect on (2) and (3) but slightly stimulated (1) and (4). $CaCl_{2}$ strongly inhibited (1), (2) and (3). $SnCl_{4}$ stimulated (3) but strongly inhibited (1), (2) and (4). EDTA (ethylenediamineteraacetic acid) accelerated (1) and (4), and had no detectable effect on (2) and (3).
