3-3. Pasting properties The pasting properties of samples were studied by means of RVA(Table 2) The RVA parameters of all samples were significantly different(p 0.05). The pasting temperature of JFSS was higher than those of CS and PS(81.58, 77.60 and 69.43 oc, respectively) Because of high amylose content, JFSS had lower swelling proper ties, and therefore exhibited higher pasting temperature than CS and PS. PS had the highest peak viscosity of 831.05 RVU, followed by JFSS and CS. A lower breakdown for JFSS than CS and PS(39.67, 66.25 and 695.30 RVU, respectively) suggests that JFSS was more resistant to heat and mechanical shear and hence less prone to loss viscosity upon holding and shearing. Mukprasit and Sajjaanantakul(2004) also reported that the breakdown viscosity of JFSS was lower than that of commercial starch(Novation 2300 and Purity 4) The final viscosity indicated the re-association of the amylose molecules during the cooling period after gelatinization and formation of a gel network. JFSS had higher final viscosity than CS and PS(364.13, 228.88 and 335.30 RVU, respectively). The amylose content of JFSS PS CS, which related to final viscosity. Setback is defined as the degree of re-association between the starch mole- cules involving amylose(Charles, 2004). The highest setback was recorded for PS and the setback of JFSS was higher than that of CS.
