A NOTE ON HEMICELLULOSE GUMS FROM BEET PULP EXTRACTED WITH ALKALINE HYDROGEN PEROXIDE

摘要

Studies at SPRI on potential added-value products have focused on gums obtained from bagasse (Godshall, et al, 2002) and on beet pulp. Beet pulp is the major by-product of the beet sugar industry, and much work has been done to elucidate its properties and composition. Although its main use today is in animal feed, a small market exists for edible beet fiber. Thibault has been in the forefront of characterizing beet pulp for added value (Thibault and Bonnin, 2000)and has been especially interested in its ferulic acid content (Micard, et al., 1997; Colquhoun, et al., 1994; Ralet, etal, 1994; Micard, etal, 1994, Berlin, etal., 1988). Sun and Hughes (1998) conducted fractional alkaline extraction of sugar beet pulp. Studies by Godshall on sugarcane bagasse, using the alkaline hydrogen peroxide procedure of Doner to extract hemicellulose (Doner, et al., 1998.), showed a yield of about 6.5% from bagasse of a highly purified arabinoxylan (Godshall, et al., 2002). The same procedure was used to extract hemicellulose from industrial sugar beet pulp.
