A Novel Pectin Material: Extraction, Characterization and Gelling Properties
AbstractA novel pectin was acid extracted from chickpea husk (CHP). CHP presented a 67% (w/w) of galacturonic acid, an intrinsic viscosity of 374 mL/g and a viscosimetric molecular weight of 110 kDa. Fourier transform infrared spectroscopy spectrum of CHP indicated a degree of esterification of about 10%. The CHP-calcium system formed ionic gels with a storage (G’) modulus of 40 Pa and gel set time (G’ > G’’) of 3 min at 1% (w/v), and a G’ of 131 Pa and gel set time of 1 min at 2% (w/v). The G’ of CHP gels was not greatly affected by temperature. The results attained suggest that chickpea husk can be a potential source of a gelling pectin material.
