The Importance of Product Traceability
The Importance of Traceability.
Of prime importance to consumers is the knowledge that what is on the label is what is in the bottle. The Olive Oil industry is no different to any other industry, and this is especially true at the present time, when margins are under constant pressure – the potential for fraud exists. Olive oil fraud comes in two main varieties, 1) miss-labelling/miss-selling and 2) adulteration.
Miss-labelling & Miss-selling
One of the constant worries facing consumers is that what they are buying is olive oil. Is your olive pomace oil olive pomace oil or is it blend, is it extra virgin olive oil or lampante, or an olive pomace blend. How can you be sure? There are a few simple steps, first ask yourself is the price too good to be true, if it is then there is a strong probability that the reason for this is that it is not the product that they say it is. Second, are you working with a reputable supplier, whilst even the largest firms have been duped, larger firms conduct regular quality audits and buy from reputable sources. Three, ask for a full technical analysis and product specification. Ask your supplier to provide all the factories certification and accreditation and finally spot check the product for yourself. If you work with a company such as Campden BRI you can get your oil analysed for a relatively modest fee.
A 2010 report by the University of California’s Davis Olive Centre, found that 69% of imported olive oil samples and 10% of California olive oil samples labelled as extra virgin failed to meet the IOOC and United States Department of Agriculture (USDA) standards for extra virgin olive oil. Teams from the Australian Oils Research Laboratory in Wagga Wagga, New South Wales and the University of California at Davis Olive Centre analyzed 14 imported brands and five California brands of extra virgin olive oils from three different regions of California.
The two laboratories evaluated the oils based on standards and testing methods established by the IOOC and USDA and as well as several newer standards and testing methods adopted in Germany and Australia. The tests found that in the majority of cases samples of imported olive oil labelled as “extra virgin” and sold at retail locations in California did not meet the criteria for extra virgin olive oil set out by the IOOC and the USDA. Sensory tests showed that these failed samples had defective flavours such as rancid, fusty, and musty. These negative sensory results were supported by chemical data in 86% of the cases.
The report was critical of the standards put in place by the IOOC and USDA and concluded that the IOOC/USDA standards would be more effective in assessing and enforcing olive oil quality by including another test referred to as the German/Australian DAGs standards which were recently adopted in Germany. Oil often fails to meet quality standards for a number of reasons three of which are oxidation by exposure to elevated temperatures, light, and/or aging, adulteration with cheaper refined olive oil and poor quality oil made from damaged and overripe olives, processing flaws, and/or improper oil storage. Taking all this onboard it is important to use oils with full accreditation and traceability from olive grove to table.
Adulteration
Is your olive pomace oil olive pomace oil or is it blend, is extra virgin olive oil or an olive pomace blend. Adulteration is simply the blending of the product you are buying with a cheaper alternative to lower the cost of production. This is quite a sophisticated process and the masters of this process create oils that are very difficult for the average consumer to detect. In 1997 and 1998 the European Union was forced to conclude that olive oil was the most adulterated agricultural product in the European Union.
This prompted the E.U.’s anti-fraud office to establish an olive-oil task force. The task force was disbanded after a few years, but fraud remains a major international problem. Olive oil has a much greater value than most other vegetable oils, but it is costly and time-consuming to produce and is surprisingly easy to blend without detection. Adulteration is especially common in Italy, the world’s leading importer, consumer, and exporter of olive oil.
For those who are interested there is the famous case of Domenico Ribatti, which can be read about in Tom Mueller article ‘Slippery Business’.
