Tunisia: Olive Oil Yields Patents for Local Biochemistry Researcher
A Tunisian biochemistry researcher whose laboratory specializes in the characteristics of different varieties of Tunisian olive oil, has managed to register two patents respectively on the anti-oxidant qualities of one variety of olive oil that grows in the country’s north western regions and on sterility therapy in certain animal species.
Dr Mokhtar Zarrouk who heads a research laboratory in which some 20 researchers are working, has been involved in identifying the therapeutic qualities of olive oil for many years. Dr Zarrouk’s laboratory is located on the premises of the Bordj Cedria technological park, which specializes in biotechnologies, as well as renewable energies.
In 2007 the scientific journal Biophysique, Biochimie et Biotechnologie published the results of his research, earning him the admiration of the scientific community.
Researchers from the University of Tsukuba, in Japan, which has strong ties with the Bordj Cedria technological park, have helped Dr Zarrouk patent his valuable research.
With patents respectively registered in Japan, under the patent cooperation treaty (PCT), and in France, the Tunisian scientist has received interesting offers for the industrial exploitation by the pharmaceutical industry of his findings on the anti oxidant and anti -carcinogenic properties of some varieties of Tunisian olive oil.His second discovery of an olive oil based, active principle likely to eradicate sterilty in certain female species, also yields interesting prospects.

Feeding ruminants with olive by-products enhances animal performance and product quality
By Antonio Marín Ruiz,
A study from the CSIC, Spain and the University of Wales, U.K determines that consuming products rich in oil increase the content of mono-unsaturated fatty acids and lower the content of saturated fatty acid in milk and meat of goats and sheep.
Olive leaves provide half of the energy and amino acid requirements of sheep and goats at maintenance level and, if adequately supplemented, can be used as part of the forage in diets for production.
Olive by-products traditionally represent an important group of feed resources for ruminants in the Mediterranean areas.
However, these materials are still under-exploited. Spanish and British Scientists have analyzed the inclusion of by-products from olive trees and olive oil extraction in the diets offered to goats and sheep and were evaluated with respect to their composition, digestion, degradation, ruminal fermentation, and their impact on animal performance and on product quality, with particular attention to their fatty acid profile.

Spain: Adulterated olive oil warning in La Roija
The Guardia Civil in La Rioja has warned about the possible sale of adulterated olive oil in the area.
550 litres of oil has been found in large container labelled ‘Astispumante 1510’ and it comes after the theft of 1,750 litres of oil was reported in the area on December 18.
The oil was found in the town of Rincón de Soto and samples have been sent to Madrid for toxicology study.
Astispumante 1510 is used as a food additive but in incorrect amounts it can lead to diarrhoea.

Compound from olive-skin pomace protects against colon-cancer
Researchers from the University of Granada and the University of Barcelona have shown that treatment with maslinic acid, a triterpenoid compound isolated from olive-skin pomace, results in a significant inhibition of cell proliferation and causes apoptotic death in colon-cancer cells.
Maslinic acid is a novel natural compound and it is able to induce apoptosis or programmed death in human HT29 colon-cancer cells via the intrinsic mitochondrial pathway. Scientifics suggest this could be a useful new therapeutic strategy for the treatment of colon carcinoma.
This study is the first to investigate the precise molecular mechanisms of the anti-tumoral and pro-apoptotic effects of maslinic acid against colon-cancer. Chemopreventive agents of a natural origin, often a part of our daily diet, may provide a cheap, effective way of controlling such diseases as cancer of the colon.

Phenols in Quality Olive Oil Suppress Breast Cancer Gene
Good quality extra-virgin olive oil contains health-relevant chemicals, ‘phytochemicals’, that can trigger cancer cell death.
New research published in the open access journal BMC Cancer sheds more light on the suspected association between olive oil-rich Mediterranean diets and reductions in breast cancer risk.
Javier Menendez from the Catalan Institute of Oncology and Antonio Segura-Carretero from the University of Granada in Spain led a team of researchers who set out to investigate which parts of olive oil were most active against cancer.
Menendez said, “Our findings reveal for the first time that all the major complex phenols present in extra-virgin olive oil drastically suppress overexpression of the cancer gene HER2 in human breast cancer cells”.
