Blends lignin-containing

Hydroxy propyl lignin (HPL) Two different HPL preparations were used in this study (12). Blends containing PE and EVA utilized an HPL from organosolv (methanol) lignin from red oak and blends containing PVA and PMMA utilized an HPL from kraft lignin (Indulin-AT from Westvaco Corporation, Charleston, SC).

The case of contradictory findings for the analysis of dietary fiber are due to differences among analytical methods employed. The AO AC total dietary fiber method measures all compounds not digested by amylase and protease and insoluble in 80% aqueous ethanol. While cellulose, pectin, hemicelluloses, gums and lignin do meet these criteria, extrusion-modified starches and proteins could also be measured as fiber. Sites formerly accessible to digestion by enzymes may be involved in new bonds or physically-hindered. Many materials used to add dietary fiber to foods contain far less than 100% fiber. Artz and co-workers (1990) found no difference in X-ray diffraction patterns of corn fiber-corn starch blends after extrusion, which was expected since very little crystalline cellulose was present. The com bran isolate used as a fiber source actually contained only 16.6% cellulose. Amorphous hemicelluloses comprised the remainder of the dietary fiber fraction. 

Modified NR latex can be also blended with lignin to produce a paperboard barrier coating in order to replace unrecyclable wax coating materials. The blends containing lignin showed a reduction of water vapour permeability in coated paper when compared with coatings without lignin. ... 

UV irradiation of IPP blends containing different concentrations of epoxidized lignin (LER) [49] led to snperficial properties modification in respect with the irradiated virgin IPP (changes depending on LER content in the mixtures) and to a prononnced photooxidation indnced by the LER presence in the stndied blends, which could act like a chromophore. 

Poly(vinyl acetate)/lignin and poly(e-caprolactone)/lignin blends were prepared by casting chloroform solutions of PVAc (Mw 140 kDa) and PCL (Mw 80 kDa) mixtures containing 9-30% by weight of lignin (Table 2).
