SWC indicates how much the fiber matrix swells when water is absorbed. PFA and PFSP had SWC values of 37.00 and 5.00 mL/g sample, respectively, the difference between them was statistically significant (pb0.05). These results obtained for PFA were higher than those obtained for other fruit fibers,including those from passion fruit pulp, peel and seeds (7.2 mL/g) A high SWC is related to the amount SDF, especially pectin. It is known that the structural characteristics and chemical composition of the fiber play an important role in the kinetics of water uptake.
