Olives Packed With Polyphenols: Polyphenol content is high in Morocco Gold

Polyphenols Present In Morocco Gold Extra Virgin Olive Oil.

This is the first of a series of articles that describe the polyphenol content of our extra virgin olive oil following on from the analysis of our 2020/21 new harvest and what they can do to improve our health.

The high polyphenol content of Morocco Gold extra virgin olive oil is dependent on three factors. First is the variety of the olive, secondly the climate and terroir of the growing region and thirdly the actual time in the growing season that the crop is harvested.

Morocco Gold is pressed from the Picholine Marocaine, the only type of olive to go into Morocco Gold extra virgin olive oil. Oil from this variety is renowned for its high polyphenol count, oxidative stability and longevity.

Thirdly, our olives are picked when the fruit is young and green. As the olives age on the tree, the colour of the olive changes to red and then black, the size of the olive increases thus producing more oil, but the polyphenol level decreases. There is a great deal of expertise within the farming community where we source our oil to ensure that the harvest is collected at the optimum time to maximise the polyphenol level in Morocco Gold extra virgin olive oil.

Extraction Process For Extra Virgin Olive Oil

“The release of phenols and the formation of volatiles are two basic components of virgin olive oil quality that directly relate to the mechanical extraction process itself. In this ambit, control of endogenous enzymes of olive fruit during processing is the most critical point in the mechanical extraction process of olive oil. In fact, the secoiridoid concentration in the virgin olive oil is largely due to the activation of the glycosidases of olive fruit that activate the formation of aglycon, while the oxidoreductases such as polyphenoloxidase (PPO) and peroxidase (POD) can catalyze their oxidation during the oil mechanical extraction process and subsequently trigger the autoxidation mechanism”.

So what does all this mean? The types of polyphenol present in extra virgin olive oil is influenced by the extraction / pressing process. To be extra virgin olive oil, the extraction needs to be done solely by mechanical means and at low temperatures. This has a direct effect on the resulting polyphenol content. There also must be no mixing or blending with other oils and no chemical additives. This is how the natural goodness and health enriching qualities of the extra virgin olive oil is preserved.

Polyphenol content in Morocco Gold Extra Virgin Olive Oil

This confirms the ongoing high quality of this rare, delicious tasting extra virgin olive oil from this wonderful new source, together with its health enhancing qualities from its high polyphenol count.

Polyphenol : 3,4 DHPEA-EDA

3,4-DHPEA-EDA is a polyphenol in the family of Tyrosols. It is synonymous with 3,4-DHPEA-Elenolic acid Di-Aldehyde and Oleuropein-aglycone di-aldehyde. It’s chemical formula is: C17H20O6

What This Polyphenol Does : It’s Role In Health Benefits

Diets in which fat is significantly provided by extra virgin olive oil have been associated with a low incidence of cardiovascular diseases. In this study the anti-inflammatory effect of 3,4-DHPEA-EDA on the endothelium was examined.

This study was based on the production of the proinflammatory chemokine CCL2, following in vitro stimulation of primary human endothelial cells. Pre-treatment of cells with 3,4-DHPEA-EDA resulted in a dose dependent inhibition of CCL2 secretion.

The effect of 3,4-DHPEA-EDA on CCL2 expression was observed at the transcriptional level. Functional data have shown that 3,4-DHPEA-EDA diminished monocyte adhesion to HUVECs. These results point on the use of 3,4- DHPEA-EDA as a novel drug aimed to prevent or reduce inflammation of endothelium.

The Endothelium, Blood Vessels and Endothelial Cells

Endothelial Cells
Endothelial Cells

Almost all tissues depend on a blood supply, and the blood supply depends on endothelial cells, which form the linings of the blood vessels. Endothelial cells have a remarkable capacity to adjust their number and arrangement to suit local requirements. They create an adaptable life-support system, extending by cell migration into almost every region of the body.

Endothelial cells form the barrier between vessels and tissues. They control the flow of substances and fluid into and out of a tissue. An impaired function can lead to serious health issues throughout the body. Endothelial cells line blood vessels and lymphatic vessels, they are found exclusively in vascularized tissue.

Endothelial cells are nearly ubiquitous throughout the body. If it were not for endothelial cells extending and remodelling of the network of blood vessels, tissue growth and repair would be impossible.
