“…The extraction method, the NMR spectrum and the physical properties identified the precipitate as lignin. In the process of extraction heat was applied up to 85°C at pH 1.1 ensuring the extracted lignin would be free of phytic acid (Brauns and Brauns, 1960).…”

A centnfugation method was developed to determine water holding capacity (WHC) of lignin, cellulose, pectin, whole locust bean gum (LBGW) and insoluble locust bean gum (LBGI) and was compared with the AACC method using cellulose, lignin and LBGI. WHC was found to be highest for LBGW>pectin>LBGI>lignin>cellulose. Solubility and chemical configuration rather than particle size, were the main determinants of WHC. The AACC method tended to overestimate WHC for cellulose, LBGI and lignin.

“…Studies analyzing the components of various lignins have implicated the presence of phenolic compounds like ferulic, vanillic, syringic, and p-hydroxy benzoic acid (Brauns and Brauns, 1960;Hartley, 1978). These or similar compounds may contribute to the antioxidant properties of lignin.…”

Since certain dietary antioxidants are generally thought to protect retinol from oxidation during digestion, lignin was tested for its antioxidant properties. Inclusion of l-lo% lignin in the rat diet resulted in an increased (SO-loo%) deposition of retinol as compared to cellulose-fed controls. Data indicate that lignin exhibits antioxidant properties in the presence of oil and probably in the presence of other fat-soluble substances (e.g. vitamins A and E). Animal experiments substantiate this hypothesis. Results suggest both the biochemical and chemical nature as well as the nutritional ramifications of these observations deserve further investigation.
