Acid-insoluble lignin

ABL contents, expressed in ferulic acid equivalents, were of the same order of magnitude as Klason and acid-insoluble lignin contents. However, this agreement was fortuitous as the ABL determination provided only... [Pg.184]

Chemical and Spectroscopic Analyses. Acid insoluble lignin (Klason lignin) contents of wood species before and after extractions were determined using a modified procedure suitable for small samples (35). [Pg.52]

The acid-insoluble lignin contents of a variety of representative lignified materials are recorded in Table 2.2.2. These values reflect generally recognized trends... [Pg.36]

The acid-soluble lignin contents of wheat straw and bamboo have been reported as 2 and 1.5%, respectively (Schoning and Johansson 1965). In such cases, where an accurate value for total lignin content is required, acid-soluble lignin must be determined and the value applied as a correction to the acid-insoluble lignin content. [Pg.42]

Analysis of dietary fiber. Total dietary fiber including both water-soluble and water-insoluble components was analysed with an enzymic method as described by Asp et al. (18). The dietary fiber was characterized by gas-liquid chromatographic assay of monosaccharides after acid-hydrolysis and gravimetric determination of acid insoluble lignin. Uronic acids were assayed with a decarboxylation method. These analyses were performed as described by Theander and Aman (19). [Pg.95]
