$HF_1$(1H KOH soluble hemicellulose fraction), $HF_2$(2H KOH soluble hemicellulose fraction) $HF_3$(3H KOH soluble hemicellulose fraction) and $HF_4$(4H KOH soluble hemicellulose fraction) were fractionated from Fuji crude cell wall and purified using Sephacryl S-500 to determine the effects of these hemicellulosic fractions on the Ca- pectate gel formation. By increasing of KOH concentration, from 1 to 4N, hexose peas became higher in led, and molecula weights, especially pentose peaks in high molecular weight. Hemicellulose fractions using gel filtration were composed of $8{sim}10$ peaks which were $10^4{sim}143{ imes}10^4$ molecular weight. Higher values of hardness, adhesiveness and gumminess were found in low molecular weight than in high molecular weight, also in hexose and uronic acid contained than in hexose contained.
