The UGR and the sugar refinery Azucarera Ebro produce two polysaccharides of interest for ...

... the food industry by using sugar beet molasses

The doctoral thesis Producción de xantano y gelano a partir de coproductos de la industria azucarera (Xanthonomas and gelling polymer production from sugar industry coproducts), carried out by Rafael Páez Valle, under the supervision of professors Emilia Quesada Arroquia and Ana del Moral García, from the University of Granada, reveals the scientific viability of the use of beet molasses as a substratum to produce Xanthonomas and gelling polymers.

In the course of these scientific works, experiments have been carried out with products derived from the sugar industry: syrup, molasses and dried beet pulp. The best results have been obtained with molasses. Such coproducts are used as food for bacterium able to excrete Xanthonomas and gelling polymers. They both are polysaccharides applicable to different fields. They are large molecules which are part of different structures in animals, plants, algae and micro-organisms. Thus, starch is very used in the alimentary industry.

The aim is to look for alternatives to traditional cultivation methods to grow bacteria synthesizing their polysaccharides. It would lower the costs creating a method from a product derived from the sugar industry. In addition, Azucarera Ebro S.L. produces alcohol, an expensive solvent necessary to purify Xanthonomas and gelling polymers.

Pastry and bread-making

In the United States and in Europe, these two microbial polysaccharides are authorized in the alimentary industry. Xanthonomas (E-415) is the most common and it is much consolidated in the current market. Only in North America, more than 1600 patents on Xanthonomas applications and production have been registered. Due to its stabilizing and thickening action, it is also used in the cosmetic and drug industries and in oil extraction.

Gelling polymers have plenty applications in the alimentary industry, like water-based gels complementation gel, confectionery, compotes and jams, cake and pudding fillings, pre-cooked meals and dairy products. The new doctor is going to continue his career in the business sector, where he will carry go on working on the process designed in the laboratory, carrying out new experiments in the company’s pilot plant.

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Im Focus: Cold molecules on collision course

Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.

How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...

Im Focus: Shrinking the proton again!

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.

It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
