The UGR patents a process to obtain a protein as a natural colorant

26.09.2006
We only have to read the labels of many commercial products to find colorants among their components.

They are natural or synthetic additives authorised by food security regulations and used to colour food and drinks in an artificial way. A research team of the Universities of Granada, Jaén and Almería have devised a process to obtain a natural colorant from the micro-algae Porphyridium cruentum.

High performance

Many marine algae are rich in proteins with fluorescent properties. They contain a kind of molecules –chromophores– which pick up and emit light. In the case of the species Porphyridium cruentum, the protein known as ficoerithrin confers the micro-algae a reddish colour. Scientists Bermejo Ruperto, of the Universidad de Jaén, José Mª Álvarez Pez, of the UGR [http://www.ugr.es], and Francisco G. Acién Fernández, Emilio Molina Grima and Mª José Ibáñez González, of the Universidad de Almería, have designed a process to obtain the B-ficoeritrina protein from this microalgae, which is characterized by its “high performance”, about 66%. According to José Mª Álvarez, researcher responsible of the group ‘Photochemistry and Photobiology’ of the Universidad de Granada, this value is “twice as much as the highest published up to now obtained with chromatographic method”. They have separated and purified amounts of this on an almost industrial preparatory scale.

An example of the relevance of this finding is the fact that the results of the research work have been included in an article of a special issue of the prestigious Journal of Chromatography.

Protein structure

Colorants are basically used in food and agriculture, pharmaceutical and cosmetic industry to improve the aspect of the products and make them more attractive to consumers. B-ficoerithrin is “very fluorescent” and its colour “looks like strawberries milkshake’s”; therefore, according to the researcher, it could take the place of other colorants.

However, the use of a compound as a colorant must be authorized by the regulations currently in force. In this sense, scientists are dealing with the study of the spectroscopic features of B-ficoerithrin. This way they will obtain information about the possible structural changes of the protein when it is subjected to extreme conditions during the production process of foodstuffs or pharmaceutical o cosmetic formulations.

On the other hand, the researchers are going to set in motion a R&D&I project with the spin-off of Almería Bioalgal Marine, S.L., a technological innovation company that works on the treatment and commercialization of microalgae aimed at the sector of aquiculture and the preparation of functional food. In addition, among the commercialized products there are pigments produced from microalgae. Biolgal Marine is part of the business projects supported by the Department for Innovation, Science and Company through the Program Campus, managed by Invercaria.

Im Focus: Interfacial Superconductivity: Magnetic and superconducting order revealed simultaneously

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Im Focus: Studying fundamental particles in materials

Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales

Studying properties of fundamental particles in condensed matter systems is a promising approach to quantum field theory. Quasiparticles offer the opportunity...

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...

Im Focus: How to inflate a hardened concrete shell with a weight of 80 t

At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).

Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...

Im Focus: Bacterial Pac Man molecule snaps at sugar

Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.

The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...
