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: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
