The Basque Institute for Agricultural Research and Development —Neiker–Tecnalia— is investigating of the use of the oil for fuel and the storage capacity of the oleaginous cakes. The technological centre is also studying different processes for improving rape and sunflower crops, the two oleaginous species that best adapt to agroclimatic conditions in the Basque Country. The project, known as Plusoleo, is funded by the Basque Government through the + Euskadi 2009 programme.
The average production of rape is 3,500 kilos per hectare and around 1,160 litres of oil can be obtained. The farmer can use the oil for own-consumption as fuel, with the consequent cost savings, or for sell it at a price of between 67 and 84 cents of a euro. The option of extracting the oil and selling it seems to be more profitable than selling the seeds. Moreover, from the 3,500 kilos produced per hectare some 2,300 kilos of oilseedcake can be obtained after pressing, which the farmer can sell or use it as animal fodder.
Applications in animal feedNutritional composition and nutritive value are two fundamental values for evaluating any food for inclusion in the diet of farm animals. The cake obtained from mechanical procedures (which are those available to farmers) has a larger content of fatty material than that obtained by industrial procedures with additional chemicals. Moreover, they provide better information on the traceability of the protein destined for animal feed. The cake obtained on the farm by simple cold pressing of the seeds has between 11 and 33 % of fatty material per kilo; the industrial cake provides only between 2 and 3 %.
At the Neiker-Tecnalia laboratories various samples of rape-cake from the Basque Country were analysed. These samples obtained between 16 and 22 % of fatty material per kilo and between 25 and 27 % of protein per kilo of cake, values which are of great nutritional interest.
Rape-cake and sunflower-cake are, moreover, rich in linoleic and linolenic acids, essential fatty acids and precursors of the Omega 6 and Omega 3 fatty acid families. Sheep fed with this material show a profile of fatty acids with enhanced nutritional qualities.
Moreover, the technological centre is also working on the Laresne project, financed by the Spanish National Institute of Agricultural Research and Technology (INIA) in collaboration with the Faculty of Pharmacy at the University of the Basque Country. Also feeding sheep with this cake fodder is studied as well as its effect on zootechnical parameters and milk quality.

The building blocks of matter in our universe were formed in the first 10 microseconds of its existence, according to the currently accepted scientific picture. After the Big Bang about 13.7 billion years ago, matter consisted mainly of quarks and gluons, two types of elementary particles whose interactions are governed by quantum chromodynamics (QCD), the theory of strong interaction. In the early universe, these particles moved (nearly) freely in a quark-gluon plasma.

Then, in a phase transition, they combined and formed hadrons, among them the building blocks of atomic nuclei, protons and neutrons. In the current issue of...
Thin-film solar cells made of crystalline silicon are inexpensive and achieve efficiencies of a good 14 percent. However, they could do even better if their shiny surfaces reflected less light. A team led by Prof. Christiane Becker from the Helmholtz-Zentrum Berlin (HZB) has now patented a sophisticated new solution to this problem.
"It is not enough simply to bring more light into the cell," says Christiane Becker. Such surface structures can even ultimately reduce the efficiency by...
A study in the journal Bulletin of Marine Science describes a new, blood-red species of octocoral found in Panama. The species in the genus Thesea was discovered in the threatened low-light reef environment on Hannibal Bank, 60 kilometers off mainland Pacific Panama, by researchers at the Smithsonian Tropical Research Institute in Panama (STRI) and the Centro de Investigación en Ciencias del Mar y Limnología (CIMAR) at the University of Costa Rica.
Scientists established the new species, Thesea dalioi, by comparing its physical traits, such as branch thickness and the bright red colony color, with the...
