“…Similar data were reported by Salvador et al (2000) with the cellulose fraction of the cassava CWM having 82% glucose. Xylose and galactose contents of the remaining CWM in the control (without enzymatic treatment) were 3 and 8%, respectively.…”

“…Xylose and galactose contents of the remaining CWM in the control (without enzymatic treatment) were 3 and 8%, respectively. These levels were much lower than the 27% xylose and 38% galactose reported by Salvador et al (2000). This could be due to enzymatic activity of the LAB in the cassava cake during incubation, which probably partially hydrolysed the soluble cell wall components.…”

“…This is also consistent with the relationship between the fiber components and the growth promotion of bifidobacteria (Tables 3 & 4). A recent study demonstrated that among the root crops, sweetpotato cell wall material had the highest amount of the pectin fraction 18 . These data indicate that the sweetpotato fiber is available as physiologically functional material.…”

The potential chemopreventive properties of the dietary fiber prepared from sweetpotato (Ipomoea batatas L.) roots were examined to promote the demand of this residue from the starch industry. Dietary fiber was prepared by treating starch granules-removed residue with α-amylase. The dietary fibers at 1% concentration enhanced the growth of Bifidobacterium adolescentis and Bifidobacterium breve in vitro among 5 species of Bifidobacterium, which exist in the human intestinal tract. Analysis of the components of these fibers suggested that their pectin and hemicellulose were concerned with a promotion effect on the growth of bifidobacteria. Water-and oil-holding capacity of the fibers in the varieties with orange-colored flesh was relatively superior to ones from the varieties with yellow-or purple-colored flesh. Furthermore, the dietary fibers adsorbed about 90% of the mutagen, Trp-P-1. Commercial sweetpotato fiber, a byproduct of citric acid production from the residue from the starch industry, had slight effect on the growth of bifidobacteria and was lower in adsorption capacity of Trp-P-1 than the fibers prepared from sweetpotato roots. These results indicate that the residue from the sweetpotato root starch industry is available as a dietary fiber with physiological functions.

“…A high starch constituent within a waste reflects an efficiency level of starch extraction process from a tapioca factory. The cassava pulp was dried below the starting gelatinization temperature of cassava starch to preserve the physical characteristics of the starch granules [11], hemicelluloses [12] and lignin [13]. Fibers content 20.1% of cassava pulp which is reported in this study was lower than previous reported by Kosugi [8], Rattanachomsri [7], Sriroth [4], Thongchul [14] which were 29%, 23.0%, 27.75% and 35.9%, respectively.…”

“…and middle lamella cell wall component of cassava pulp, was presumably comparable to fresh cassava tuber pectin 10.38% [16]. Cassava had the lowest pectin fraction (17.8%) as well as galacturonic acid content (17%) within its cell wall materials (CWM) at only 7.3% [13] among tuber crops but the highest cellulose fraction (48.2%). Pectin fraction had a slightly higher than hemicelluloses fraction and both highly influence towards both slurry viscosity and turbidity.…”

Cassava pulp, a low cost solid byproduct of cassava starch industry, has been proposed as a high potential ethanolic fermentation substrate due to its high residual starch level, low ash content and small particle size of the lignocellulosic fibers. As the economic feasibility depends on complete degradation of the polysaccharides to fermentable glucose, the comparative hydrolytic potential of cassava pulp by six commercial enzymes were studied. Raw cassava pulp (12% w/v, particle size <320 µm) hydrolyzed by both commercial pectinolytic (1) and amylolytic (2) enzymes cocktail, yielded 70.06% DE. Hydrothermal treatment of cassava pulp enhanced its susceptibility to enzymatic cleavageas compared to non-hydrothermal treatment raw cassava pulp. Hydrothermal pretreatment has shown that a glucoamylase (3) was the most effective enzyme for hydrolysis process of cassava pulp at temperature 65 °C or 95 °C for 10 min and yielded approximately 86.22% and 90.18% DE, respectively. Enzymatic pretreatment increased cassava pulp vulnerability to cellulase attacks. The optimum conditions for enzymatic pretreatment of 30% (w/v) cassava pulp by a potent cellulolytic/ hemicellulolytic enzyme (4) was achieves at 50 °C for 3, meanwhile for liquefaction and saccharification by a thermo-stable α-amylase (5) was achieved at 95 °C for 1 and a glucoamylase (3) at 50 °C for 24 hours, respectively, yielded a reducing sugar level up to 94,1% DE. The high yield of glucose indicates the potential use of enzymatic-hydrothermally treated cassava pulp as a cheap substrate for ethanol production.
