The Aristometro in conjunction with theAristoleo® Test Kit is a
laboratory in a vial providing a fast and inexpensive method to analyze olive oil phenolic content.
The most health promoting olive oils can then be discovered, verified by NMR or LC-MS/MS,
demonstrated and marketed to health-conscious consumers who are seeking high phenolic olive oils for
their enhanced health qualities. Aristometro is an instrument developed during the ARISTOIL project
and measure the combined amounts of oleocanthal and oleacein, the two most prolific phenolic
compounds found in most olive oils.
Consumers faced with a number of health claims, taste profiles and almost daily news of fraudulent olive oils on the shelf are eager to verify for themselves exactly what is in the bottle.
Aristometro is a key tool for in store demonstrations and taste events and trade shows. The olive growers themselves need a way to measure every batch of olive oil at the olive mill so they can better understand their farming methods and begin to address issues that will help them raise the phenolic content and quality, e.g. time of harvest and amount of watering.
Olive mills seeking to increase the value of their olive oil need a fast method to accurately measure the phenolic content at the point of production and separate and store the high phenolic olive oils. The wholesalers and traders require a handheld method to measure the quality of olive oil on the spot before they purchase.
The Aristometro and the Aristoleo® Kit (AA) are 2 innovative handheld tools combined to accurately measure specific health promoting phenolic compounds in extra virgin olive oil (EVOO).
Aristometro and the Aristoleo® Kit can be used in the mill at the moment of production,
the warehouse and during in-store demonstrations to prove the phenolic content of EVOO.
- Phenolic compounds in olive oil continue to astound scientists with their health benefits. “The scientists found that acute polyphenol-rich EVOO effects in healthy participants led to marked improvement in insulin sensitivity and glucose metabolism, at the same time supporting miRNA and gene expression in inflammation and immune responses. On the contrary, these biochemical and molecular effects of EVOO were largely absent in patients affected by metabolic syndrome or participants who consumed low-polyphenol EVOO suggestive of a putative role for the phenolic component.” http://www.oliveoiltimes.com/olive-oil-health-news/health-benefits-high-phenolic-olive-oils-decoded-gene-expressions/52578
- Since the EU 432/2012 health claim labelling regulation came into effect consumers’ awareness in relation to the health benefits of high phenolic olive oil have increased. Health Claim allowed on the label: “Olive oil polyphenols contribute to the protection of blood lipids from oxidative stress.” Minimum requirement: “The claim may be used only for olive oil which contains at least 5 mg of hydroxytyrosol and its derivatives per 20g of olive oil. In order to bear the claim information shall be given to the consumer that the beneficial effect is obtained with a daily intake of 20 g of olive oil.”
- Up until recently we lacked the tools to accurately measure specific phenolic compounds in olive oil. Polyphenols degrade depending on their concentration at time of bottling. Light, oxygen, temperature and time take their toll and they must be monitored in order forconsumers to receive the minimum required healthy dose of polyphenol rich olive oil. AA can be useful devices to monitor the quality all along the supply chain.
- While olive oil consumption remains low in China and India, the most affluent householdsare becoming more receptive to the health properties of olive oils compared to other typesof oils, alongside being more often exposed to foreign cuisines using olive oil. http://blog.euromonitor.com/2015/08/whats-new-in-oils-and-fats-in-2015-olive-oil-vs-other-oils-a-case-of-quality-against-quantity.html
- The premium positioning of olive oil has helped producers from the EU cushion the blowfrom lower production levels, thanks to their high unit prices. However, they remain toodependent on their domestic markets and would benefit from targeting more aggressively the rising demand in emerging markets fuelled by interest in cuisines from Mediterranean countries and their health properties.
- Consumer studies have established the main reason people buy olive oil is for health. Most people would be willing to pay a higher price for additional health benefits. Many if not most consumers have been cheated at some point due to improper labelling, poor storageconditions, substandard olive oil.
Aristometro is an important development for 3 reasons:
- EASE OF USE. Aristometro requires the user to compare the colour liquid to a colour chart to arrive at a value for concentration of the phenolic compounds contained in the olive oil sample. Approximately 10% of the male population in the EU have some degree of colour-blindness. Another large percentage have a decreased ability to make a judgement based on their insecurity or lack of experience. The Aristometro is specifically calibrated to detect the shade of green and provide the result electronically. The results are analyzed and delivered in real time. The accuracy is 95%+ as compared to the NMR. Long term we foresee the Aristometro being verified and officially certified for its accuracy and become a standard analytical device in olive oil laboratories
- RAPID& ACCURATE RESULTS. The Aristometro analysis is only 25 minutes.
- TRACEABILITY, ACCOUNTABILITY& PROOF. The Aristometro and Aristoleo® kit can be used to test the quality of samples tested, photographed and used as a visual demonstration of high phenolic olive oil.
