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: Scientists channel graphene to understand filtration and ion transport into cells

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.

To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...

Im Focus: Towards data storage at the single molecule level

The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.

Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
