“…The concentration of total sugars was measured using the phenol-H 2 SO 4 method (OD 490 nm) using glucose as the standard sugar (Dubois et al, 1956). These procedures were performed according to the method reported previously (Shiiba et al, 1992;Shiiba et al, 1993). Chemical Industries Ltd., Tokyo) were used as the standard (Katapodis et al, 2003).…”

“…For example, to control high blood pressure or decrease the LDH cholesterol concentration in serum (Kodama et al, 1996;Lopez et al, 1999), hemicellulose prepared from cereals such as rice or wheat bran and was applied as a functional food. Shiiba et al developed an efficient method of preparing hemicellulose oligosaccharides from wheat bran using a high-temperature treatment followed by an enzymatic reaction using cell-wall lytic enzymes, including cellulase and beta-xylanase (Shiiba et al, 1992;Shiiba et al, 1993). Additionally, it was reported that their hydrolysed oligosaccharides possessed a bifidobacterium or lactobacilli activation factor (Morishita et al, 1993).…”

Bamboo hemicellulose hydrolysate (BHH) was extracted from bamboo by high temperature and enzymatic treatment. The ratio of total sugars in BHH was 75.7% on a dry matter basis (sugar components: 46.4% glucose, 12.7% arabinose, 40.9% xylose). These were mainly comprised of low molecular weight oligosaccharides containing ferulic acid. BHH exhibited strong anti-oxidative activities. In high fat (HF) diet-fed mice, 5% BHH supplementation significantly ameliorated increases in plasma cholesterol levels compared to the control mice fed HF diet alone. Also, while the fecal pH of control mice increased, that of test mice (5% BHH supplementation) did not increase to similar levels. Greater amounts of propionic acid were detected in the feces of HF diet-fed mice fed HF supplemented with BHH than one fed HF diet alone.

Obesity is a global epidemic associated with a higher risk of cardiovascular disease and metabolic disorders, such as type 2 diabetes. Previous studies demonstrated that chronic feeding of steamed wheat bran (WB) decreases obesity. To clarify the underlying mechanism and the responsible component for the anti-obesity effects of steamed WB, we investigated the effects of dietary steamed WB and arabinoxylan on postprandial energy metabolism and blood variables. Overnight-fasted male C57BL/6J mice were fed an isocaloric diet with or without steamed WB (30%). Energy metabolism was evaluated using an indirect calorimeter, and plasma glucose, insulin, and glucose-dependent insulinotropic polypeptide (GIP) levels were measured for 120 min after feeding. We similarly investigated the effect of arabinoxylan, a major component of steamed WB. Mice fed the WB diet had higher postprandial fat oxidation and a lower blood GIP response compared with mice fed the control diet. Mice fed the arabinoxylan diet exhibited a dose-dependent postprandial blood GIP response; increasing the arabinoxylan content in the diet led to a lower postprandial blood GIP response. The arabinoxylan-fed mice also had higher fat oxidation and energy expenditure compared with the control mice. In conclusion, the findings of the present study revealed that dietary steamed WB increases fat oxidation in mice. Increased fat oxidation may have a significant role in the anti-obesity effects of steamed WB. The postprandial effects of steamed WB are due to arabinoxylan, a major component of WB. The reduction of the postprandial blood GIP response may be responsible for the increase in postprandial fat utilization after feeding on a diet containing steamed WB and arabinoxylan.

“…Cereals, such as wheat bran and corn bran, are the main suppliers of dietary fiber. Their structures have been studied in detail (Brillouet et al, 1982;Shibuya, 1984;Kamisaka et al, 1990; Shiba et al, 1992), and it is known that the corn bran cell wall mainly consists of arabinoxylan and that one part of it is esterified with ferulic acid and glucuronic acid (Kato, 1992). Fermented products of dietary fiber by intestinal bacteria, especielly short-chain fatty acids, are absorbed and used as a source of energy or physiologically active substances (Chen et al, 1984;Aoe et al, 1988;Ikegami et al, 1995).…”

Enzymatic activities in cecal contents were studied on rats fed on high cholesterol diets with ferulic acid arabinoxylan ester (FAX) and arabinoxylan (AX); both were processed from refined corn bran (RCB) and were compared with those of cellulose(CE)-and RCB-fed rats. The enzymatic activities in the ceca changed according to the diets. Xylanase activity, arabinofuranosidase activity and ferulic acid esterase activity appeared in the cecum of the FAX-and AX-fed rats, but these activities were not observed in the cecum of CE-and RCB-fed rats. FAX and AX showed a tendency to decrease serum cholesterol levels. At first, xylanase and arabinofuranosidase were supposed to attack the FAX and AX main chain and side chain, and thus high molecular weight FAX and AX became lower molecular weight fragments. At that time, ferulic acid esterase was presumed to attack and FAX was degraded lower. These enzymes might act synergistically.
