Chemical analyses were recently carried out on green olive oil produced in 2019, which demonstrate that the comprehensive use of zeolite in olive cultivation can yield an exceptional olive oil of the highest quality. <\/p>\n\n\n\n

This olive oil meets all the requirements to bear a \u2018health claim\u2019 following the necessary standardisation and certification procedures under current legislation.<\/strong><\/p>\n\n\n\n

The analyses were carried out by the chemical analysis laboratory of Synchroni Analytiki, in Trilofo, Thessaloniki. The laboratory is accredited to ISO 17025 by the Hellenic Accreditation Council (ESYD),\u00a0and participates in scientific research activities as well as interlaboratory proficiency testing schemes.<\/p>\n\n\n\n

The olive trees are of the Koroneiki variety and are located in the wider Gargalianoi area, in the prefecture of Messinia.<\/p>\n\n\n\n

During production, only certified organic fertiliser has been used, along with the incorporation of 8 kg of zeolite for 3 consecutive years. In total, 24 kg of zeolite, with a particle size of 2.5 to 5 millimetres, has been used per tree.<\/p>\n\n\n\n

What is the \u2018health claim\u2019 for olive oil?<\/h2>\n\n\n\n

According to European Regulation 432\/2012 (L 136\/25.05.2012), olive oil may bear a \u201cHealth Claim\u201d if it has a high content of biophenols or polyphenols. The concentration of polyphenols in one kilogram of olive oil must be at least 250 mg. In this case, from December 2012 onwards, the following health claim may be printed on olive oil packaging:<\/p>\n\n\n\n

\n

\u2018The polyphenols in olive oil help protect blood lipids from oxidative stress as part of a varied and balanced diet\u2019. \u00a0<\/p>\n<\/blockquote>\n\n\n\n

It has been demonstrated that daily consumption of 20g of olive oil bearing a health claim provides at least 5 mg of hydrotyrosol and its derivatives, which help protect blood lipids from oxidative stress.<\/p>\n\n\n\n

Specifically, the complex of oleasine, oleocanthal and derivatives contained in the above concentration has protective properties for human health, has a positive effect on the prevention of heart attacks, helps to combat inflammation, whilst recent research has shown that it offers protection against Alzheimer\u2019s disease.<\/p>\n\n\n\n

Ideally, an olive oil with a \u2018Health Claim\u2019 is recommended for consumption as a dietary supplement.<\/p>\n\n\n\n

Ultra Premium olive oil category<\/h2>\n\n\n\n

Ultra Premium (UP) is a category of olive oil that designates the highest-quality olive oil in the world. The UP standard was created by Veronica Foods as a solution to the growing need to distinguish high-quality extra virgin olive oil.<\/p>\n\n\n\n

We note that, according to the chemical analysis, this particular olive oil, based on the values tested, could also be categorised on this scale.<\/p>\n\n\n\n

Explanation of test results<\/h3>\n\n\n\n

Acidity<\/h4>\n\n\n\n

This is the most fundamental criterion for assessing the quality of olive oil and is what determines its commercial value.\u00a0 It is expressed in grams of free oleic acid per 100 grams of fat. Therefore, when a label states an acidity of 0.5% (or 5 grams, according to the producer), this means that 100 grams of olive oil contain 0.5 grams of free fatty acids.<\/p>\n\n\n\n

K270<\/h4>\n\n\n\n

This is an indicator of an advanced stage of oxidation (rancidity) or refining. Given that refined olive oils have a high K270 value, this parameter provides information on any possible adulteration of the olive oil. Furthermore, both old olive oils and blends of old olive oils exhibit a high index.<\/p>\n\n\n\n

K232<\/h4>\n\n\n\n

This is an indicator of the initial or intermediate stage of oxidation. A high value indicates a slow or outdated production method, as well as the storage of the olive oil in question for a long period of time.<\/p>\n\n\n\n

\u0394\u039a<\/h4>\n\n\n\n

It is defined as a mathematical formula for calculating ultraviolet absorption coefficients. To be precise, the measurement of olive oil\u2019s absorption in the ultraviolet spectrum is used to assess its quality, its authenticity (checking for adulteration of olive oil with refined olive oils or seed oils) and to determine its oxidative deterioration.<\/p>\n\n\n\n

Peroxides<\/h4>\n\n\n\n

These are chemical compounds formed mainly by the reaction of oxygen with olive oil. A high peroxide value indicates oxidative deterioration and therefore a short shelf life for the olive oil<\/p>\n\n\n\n
