Crystallinity index of pectin
WebFurthermore, we noticed that the crystallinity index varied significantly from 75.8 for flax (−) to 80.3% for flax (+), with p-value = 1.98 × 10 −2. ... The degradation of the middle lamella, mostly made of pectin, explains the loss of elasticity properties due to retting. The middle lamella degradation decreased the internal cohesion ... WebThe crystallinity index of samples was calculated using the height ratios between the intensities of the crystalline peak (I002-Iamorph) and total intensity (I002) [17,18]. The samples were scanned by a Bruker D8 Advance X-ray diffractometer (under a voltage of 40 kV and a current of 50 mA) (Bruker, Karlsruhe, Germany) in the range of 5° to 50°.
