Results indicates that ash allowed differential diffusion of gases. Sufficient O2 diffused into the inner portion of the ash pile allowing normal respiration of stored fruits while CO2 and C2H4 were temporarily trapped before gradually diffusing outward. Ripening of fruits in moist ash on the other hand was comparable from that of the control inspite of light C2H4 accumulation due to the evaporative cooling effect of water in the ash. Good physical attributes were observed in tomatoes stored in dry moist ash than the control. TSS (total soluble solids (Brix)), T.A. (tetratable acid (%)) and pH of tomatoes stored in dry ash were comparable to that of the control. lower than those in dry ash and control. H2O absorbed by the fruits from moist ash contributed by dilution to the significant decrease in TSS and TA of all moist ash treated fruits
