“…This can be explained by the hydrolysis process that would reduce the amount of complex carbohydrates present in the sample. Arabinose and xylose concentrations are consistent with hemicellulose concentrations reported previously (20,23). Arabinoxylan is the main hemicellulose in CF.…”

“…The high variation is due to the fact that some samples arrived directly after wet milling, while other samples were dried before they were shipped. Organic matter concentrations were very uniform, ranging from 98.8% to 99.8%, consistent with values reported previously (20)(21)(22)(23)(24). Ingredients with low ash concentrations are particularly useful for the manufacture of pet foods.…”

“…Beet pulp, which is used in many high-quality dog foods, usually has high ash concentrations that can limit its use as a fiber source for dogs. Crude protein concentration of CF ranged from 10.4% to 15.9%, consistent with literature values (20)(21)(22)(23)(24). Hydrolyzed corn fiber had the highest average CP concentrations (14.4%).…”

“…Glucose contents were lower for CF after hydrolysis, as expected. However, on the basis of the average glucose concentration in NCF (282.9 mg/g of DM), it may be inferred that there is starch remaining in NCF because glucose in CF comes mainly from two components, starch and cellulose, and the content of the latter in CF has been reported to be in the range of 10-16% (20,23,25).…”

The objective was to examine the chemical composition, in vitro fermentation characteristics, and in vivo digestibility responses of fiber-rich corn coproducts resulting from corn wet milling. Native corn fibers, native corn fibers with fines, hydrolyzed corn fibers, and hydrolyzed extracted corn fibers were analyzed chemically and their capacity to produce short-chain fatty acids determined. Ash content was low (<1.2%), crude protein content varied little, but fat and fiber concentrations varied widely. Most fiber was in the insoluble form, with glucose being predominant followed by xylose. Total short-chain fatty acid production ranged from 211.6 to 699.52 µmol/g of dry matter, whereas branched-chain fatty acid production was low. Four corn fibers (native and processed) were included in a canine diet matrix at the 7% inclusion level. Nutrient digestibility, food intake, and fecal characteristics were not affected by corn fiber inclusion in canine diets, suggesting that they should be considered as potential dietary fiber sources in dog foods.

“…Corn fibre is an abundant and inexpensive by-product of the corn wet milling process, which contributes to about 10% of the grain dry matter [14]. It is utilized mainly as low-value animal feed, however, as the market of animal feed is limited, the increase of the corn processing may result in market problems for the excess [15].…”

Corn fibre, a co-product of corn wet milling, can be a suitable raw material of a biorefinery producing biofuels and valueadded chemicals. The simulated process is able to produce bioethanol, biomethane and xylitol synergistically, while it also covers its own heat demand. The proposed plant consists of the following process steps: fractionation, enzymatic hydrolysis and ethanol fermentation, distillation and dehydration, anaerobic digestion, biogas upgrading, aerobic waste water treatment, combined heat and power production, xylitol fermentation and recovery. Various scenarios of the biorefinery were investigated and the process configurations were compared in terms of energy efficiency, or mass flows of the products. Incineration of the sludge and production of district heat are found to be effective methods to increase the energy efficiency, on which aerobic sludge yield has a great effect. The solid-liquid separations, which are carried out in filterpress, have a curial role in terms of energy efficiency. Combustion of the solid part of cellulose hydrolysis residue is favourable compared with the anaerobic digestion, except if the dry matter content of the filterpressed solid was set to 30% instead of 40%. The amounts of the produced xylitol and biomethane are variable, which ensures the ability of market adaptation for the biorefinery.

BACKGROUND The high cost of pure arabinose has resulted in a growing demand to develop new cost‐effective methods of arabinose production from lignocellulosic and pectin‐rich materials. Corn fibre is an inexpensive by‐product of the corn wet‐milling process, and is a promising raw material for producing arabinose and other value‐added products. In this study fast dilute sulphuric acid hydrolysis of corn fibre was investigated for selective arabinose solubilization. Acid concentration and reaction time of hydrolysis of destarched ground corn fibre and raw corn fibre were 0.25–5 w/w% at 5–15 min and 0.25–1.25 w/w% at 25–75 min, respectively. Results were evaluated statistically and model equations were developed to predict the yields of sugars. RESULTS In the case of raw corn fibre the most favourable conditions were 1.1 w/w% sulphuric acid concentration and 51 min reaction time at 90°C, where a total arabinose yield of 75.9% was achieved with satisfactory selectivity. In the case of destarched ground corn fibre at a sulphuric acid concentration of 4.6 w/w%, a reaction time of 5 min and a temperature of 90°C, a total arabinose yield of 80.5% could be achieved with satisfactory selectivity, according to the model equations. CONCLUSION Arabinose‐rich liquid fractions were produced by mild sulphuric acid treatments of corn fibre. Based on the models developed the mono‐ and oligosaccharide contents of the hydrolysates can be controlled under the conditions investigated. © 2014 Society of Chemical Industry
