Antioxidants, plastics could be made from byproducts of wheat milling — ScienceDaily – News

It’s usually used as livestock feed, but wheat bran’s value in human nutrition and medicine may soon reach its full potential with a new sustainable processing method developed by Swedish researchers.

As a commodity, the least valuable part of the wheat grain is the bran — the outer coating of the kernel, which is typically sold as animal feed. Now researchers at KTH Royal Institute of Technology in Stockholm have developed a process to extract valuable biomolecules from this offal which could be used as antioxidants, prebiotics and even food packaging material.

The extraction process uses only hot, high pressure water and carbohydrate-active enzymes to harvest wheat bran’s hemicelluloses and oligosaccharides. This process allows these polysaccharides to retain their antioxidant properties — which are stripped away through ordinary alkaline extraction techniques.

Andrea Ruthes, postdoctoral researcher, and Francisco Vilaplana, associate professor in Glycoscience at KTH Royal Institute of Technology are the scientists behind this discovery, which was reported in the recent issue of the journal Green Chemistry.

“In bran and other cereal tissues, the hemicelluloses are difficult to extract because they’re tighly interconnected and recalcitrant,” Vilaplana says. One way to do it is with alkaline, but that also destroys the part of the molecule that gives it its antioxidant functions.

“We use a cascade approach where we first extract the hemicelluloses in polymer form and then we use the enzymes to selectively tackle the un-extractable residue. In this way we maximize total yields of valuable biomolecules from the bran,” he says.

Vilaplana says his research group is studying possible applications for these biopolymers, including active food packaging films and thickeners that provide a natural, non-additive way to prevent oxidation. In medicine, they could also be used to encapsulate oxygen-sensitive active compounds and to reduce the inflammation caused by reactive oxygen species (ROS) in biomedical applications.

The hemicelluloses and oligosaccharides are also well-known to have prebiotic properties as dietary fibres, which are important for improved nutrition and human health.

“Our process could contribute over the long term to use of cereal hemicelluloses with antioxidant activities in many ways, such as non-fossil based packaging, preserving sensitive foods or drugs from oxidation, dietary fibre supplements and texturizing gels in food and cosmetic products.

Benefits & Features

Coal Bowl Scraper Benefits

Dependable Coal Management and Hauling

Dual Engines

Dual Engines allow Coal Bowl Scrapers to achieve maximum payloads and deliver fast cycle times.

All-Wheel-Drive

All-Wheel-Drive allows the machine to work effectively in poor underfoot conditions and climb piles of slippery, loose coal.

Large Capacity Coal Bowls

Coal Bowls are longer and higher than standard scraper bowls, which allows you to haul 50 cubic yards (38 cubic meters) with a 637G.

Compaction Capability

Coal bowl scrapers are effective in compacting coal, which reduces the risk of spontaneous combustion of coal in the stockpile by eliminating the air spaces.


Coal Stockpile Management

Coal Bowl Scrapers are the ideal stockpile management tool.

Maintaining the Coal Stockpile

Coal Bowl Scrapers are effective in compacting coal, which reduces the possibility of spontaneous combustion in the coal stockpile. This allows your company to meet plant safety regulations and eliminates the need for additional compaction equipment.

Reclaiming Coal from the Stockpile

When incoming coal shipments cannot satisfy your coal burn requirements, you need a way to reclaim the coal off the stockpile. Coal Bowl Scrapers can move coal from the stockpile to the inlet supply of the plant.

Building the Coal Stockpile

Coal Bowl Scrapers allow you to create your coal stockpile by self-loading coal in the receiving area, hauling it to the stockpile area, and dumping coal in thin lifts.

Heavy Construction News – Research team discovers new ore-forming process in ancient marine sedimentary basin — ScienceDaily

Heavy Construction Photos

At a first glance, the Witwatersrand basin, the largest known gold resource on our planet, is not automatically related to ocean research. However, in its 3 billion years old geological history, the Witwatersrand basin in South Africa has been covered by seawater, but experienced also episodes of drying out, flooding and erosion by rivers and the repeated coverage by seawater. In 1852, the English prospector J.H. Davis discovered the first gold in the Witwatersrand, leading to the South African gold rush and the discovery of much more gold deposits within the basin. Although the Witwatersrand has been subject for decades of research, the genesis of gold and uranium ore is still unclear.

A group of scientists from Canada and the GEOMAR Helmholtz Centre of Ocean Research Kiel, successfully unravelled some mechanisms of the ore-forming process using complex analytical techniques. The results were recently published in the scientific journal Precambrian Research.

In this study, the scientists analysed samples from the Witwatersrand ore deposits with high-resolution scanning- and transmission-electron microscopes, and the processed their data using novel 2D and 3D software. “We were able to find out that fossil oil, that has been formed by organic matter derived from the first living organisms on Earth, mobilized uranium in the basin. Uraninite nanoparticles flocculated in the oil and formed uranium ore,” explains Dr. Sebastian Fuchs from the GEOMAR, the first author of the study. “Hot hydrothermal fluids, similar to those fluids that we find today in modern seafloor Black Smoker systems, transported dissolved gold and formed oil-in-water emulsions at the site of the deposits. The oil droplets in the hydrothermal fluids initiated the efficient chemical precipitation of native gold and the formation of very complex-structured gold and uranium ore.”

Using high-resolution imaging techniques, the researchers were able to visualize a to date unknown ore-forming process, in which migrating oil plays the dominant role in the distribution and concentration of metals. “With our method we have been able to show remnants of fossil oil entrapped in gold for the very first time” says Dr. Sebastian Fuchs.

“We are surprised to see such an intimate spatial relationship between the oil products and the metals,” reports Dr. Fuchs. “We hope that our study gives new impulses to industry and science to explore new mineral deposits. Perhaps it is possible at some day to extract gold and other metals from mined crude oil.”

With the methods used, it is now possible to study not only ore particles on the ocean floor in the range of millimetre to nanometre, but also the smallest fossils and living organisms, such as micro-organisms. “We are curious about what else we might discover on the ocean floor in the future,” Fuchs concludes.
