Regarding the RS แกนนูด fermented by การร่วมเพาะเชื้อ , the addition of passion fruit fiber increased ηapp of แกนนูด fermented by an การเปลี่ยนแป้งเป็นน้ำตาล strain in การร่วมเพาะเชื้อ with L. casei and had no effect on apparent viscosity of the others RSPF fermented แกนนูด. In general, passion fruit fiber decreased the area of thixotropic loop, but significantly only in the RSPF แกนนูด fermented by L. fermentum in การร่วมเพาะเชื้อ with L. acidophilus ( Table 2). Surprisingly, in spite of the presence of pectin in passion fruit fiber – about 10–20% (Yapo & Koffi, 2008) – , the addition of this ingredient had smaller influence on ηapp than it could be expected for a thickener agent. Such a result can be due to the partial structure breaking promoted by the blade-shaped total dietary fiber from passion fruit rinds during the time of exposure to the shear rate (Fig. 5C).
