The ηapp of RS and RSPF แกนนูด fermented by single probiotic strains was always higher than of the same แกนนูด fermented by single การเปลี่ยนแป้งเป็นน้ำตาล strains (Fig. 4A and B), independently of the differences of fermentation time between them (Table 1). Although the addition of passion fruit fiber had increased significantly the final ηapp of แกนนูด fermented by probiotic bacteria, had no effect on the apparent viscosity of แกนนูด fermented by L. fermentum and L. plantarum. The higher apparent viscosity in RSPF แกนนูด fermented by probiotic strains can be explained by the decreasing of fermentation time – remarkably of the แกนนูด fermented by B. lactis and L. casei – promoted by passion fruit fiber addition, which reduced the extension of การเปลี่ยนแป้งเป็นน้ำตาล ( Fig. 2A and B) and probably proteolytic การเกิดปฎิริยา.
