    1.- Introduction

Unquestionably olive oil is the main ingredient of the Mediterranean Diet.

Long ago, people from different races and ethnic groups, such as Arab, Jew, Sephardi, Iberian, Turkish, Italian..., have used the dense and aromatic fats from the olive tree to anoint the forehead of kings, the body of princesses, smoothen children skin or to shroud dead bodies. When it was burnt its light lighted cities, heated homes and helped writers and painters to create eternal works of art.

For the Mediterranean cultures the olive tree was a gift of nature. People considered it as a wisdom, progress and balance symbol. The Dove of peace released by Noah after the Flood, came back with one of its branches in her beak. The medicinal and nutritious uses of its fruit, go through the digestive and cardiovascular systems, improving health and delaying ageing process.

    2.- But, what is Olive Oil?

The Spanish food system defines it as the oily liquid extracted from the ripe fruits of the olive tree (olea europaea) without having undergone manipulation or unauthorised treatments.

According to its commercial features, olive oil is an oily juice, with a clean and transparent appearance, with a special aroma and taste and variable colour ranging from yellowish green to light yellow. When we talk about “oil” we always mean olive oil.

Olive oil has different types having their own specific features. But before talking about this, we will review the elaboration method of olive oil, which to a great extent is still the same as it was hundreds years ago.

    3.- Olive oil elaboration

Olives reach their ripeness in early autumn, picking starts at the end of November and lasting up to the month of March. There is a Spanish saying “por Santa Catalina todo su aceite tiene la oliva”. The methods to harvest them have changed very little from the ancient time nowadays. The most common way is to extent canvases at the foot of the trees, where the olives will fall when the tree is beaten (using flexible poles).

Olives are transported to the oil mill for grinding and pressing.

The different stages of the olive oil elaboration process are as follows:

Traditionally agricultural workers have cleaned the fruit in the fields, by means of sieves. But this cleaning is not complete, so the fruit goes into the olive-oil mill with a great quantity of impurities, leaves, branches, mud, etc which is necessary to eliminate. So, for this purpose they use cleaners which, through an air current and shaking sieves, eliminate leaves, branches, etc. And then, if it is necessary, they use washing devices which eliminate stones, dust,...

Once the fruit has been cleaned and weighted, it is stored in hoppers until it can be crushed. The storage period must be as short as possible in order to avoid alterations, which will produce oils with a higher degree of acidity, lower stability and worse flavour.

Oil is found in the olive in drop form and to extract it, a grinding of the fruit is necessary in order to destroy the vegetable tissues, which aforementioned drops contain. Olives are introduced in the mills and after being ground we get a paste which is beaten to make the separation of oil easier in the following processes.

The beaten paste is treated by pressing (traditional system) or by centrifugation, to extract the liquid part, formed by the oil and the alpechin in one hand and the solid part formed by refused and alpechin, on the other hand.

The alpechin or vegetable water is a waste, which must be eliminated.

The following stage consists on separating the olive oil from the vegetable water. This is carried out with different techniques (decantation, centrifugation, or mixed system).

Once the olive oil has been extracted, and without undergoing any other manipulation, we obtain theVirgin Olive Oil, which is stored until its bottling.

    4.- Types of olive oil

Taking into account the organoleptic features, the presence of defects and the acidity degree, virgin olive oil is classified into four types:

Lampante virgin olive oil is refined by means of physical and chemical procedures

(solvents). During this process there is a loss of nutritional values.

Refined olive oil is mixed with virgin olive oil so that it is suitable for human consumption. This will be the fourth type of olive oil, which is marketed (provided that lampante cannot be marketed) and this is olive oil.

The acidity degree of olive oil does not indicate its quality, this just depends on the consumer´s preference. A higher acidity degree provides a more intense flavour, but all types may have different acidity degrees (0.4º, 0.5º, 0.7º, 1º...) apart from all the aforementioned for each type.

    5.- Other oils

We should not confuse olive oil with many other oils that can be found in the market. These oils such as sunflower, soya, corn, rape or refuse are suitable for cooking but olive oil stands out for its higher quality which can be mainly distinguished by its exquisite flavour, colour and consistency. The nutritional values and health benefits that it provides make it superior to any other oil found in the market. On the other hand its stability makes it suitable to be used many more times than any other, that is why it goes further for cooking.

    6.- Olive-pomace oil

There is another oil which can be obtained from the olive, this is olive-pomace oil, which is obtained from the refuse (solid part which remains after grinding and pressing the olives). It is usually formed by rests of pits, skin, pulp, water, etc.

This refuse is treated with solvents (ethylene chloride and exano) to extract the oil that still remains in this paste. Afterwards oil is heated to evaporate the solvents. These processes result in crude olive-pomace oil. Then it undergoes a refining process to eliminate impurities and substances, which produce a defective flavour. They use soda, high temperatures, deodorants and bleaching. After obtaining refined olive-pomace oil,

it is mixed with virgin olive oil ( in a proportion of 90/10 or 80/20) and olive- pomace oil is obtained.

    7.- Nutritional properties of olive oil

Olive oil is a food whose nutrients are almost exclusively lipids or fats. The most important components of olive oil are the triglicerides and the fatty acids no insaturated, being very important the content of oleic acid.

The proportion of these fatty acids is the ideal one from the nutritional point of view:

Palmitic acid 7.5-20%

Palmitoleic acid 0.3-3.5%

Estearic acid 0.5-5%

Oleic acid 55-83%

Linoleic acid 3.5-21%

Linolenic acid 0.0-1.5%

But apart from lipids, olive oil is rich in E vitamin and polyphenols, powerful antioxidants which are lost in the refining processes.

All this gives olive oil an incalculable nutritional value as among other things, its fatty acids have the property of reducing the level of LDL-cholesterol and increasing HDL-cholesterol, which helps to reduce the number of cardiovascular diseases.

    8.- Olive oil beneficial effects for health

Mediterranean countries have a higher life expectancy than northern European countries and the United States. This is mainly due to environmental factors and especially to the food. There are scientific evidences, which show how olive oil is beneficial to prevent cardiovascular diseases, diabetes and cancer.

For many people fat is harmful for health. However it is an essential nutrient and indispensable for life. Apart from making food more appetising and its energetic function, fat has also a plastic function, joining the tissues and corporal organs and determining the functionality of the cellular membranes.

It also regulates the cholesterol metabolism, provides essential fatty acids and vitamins and it is necessary to keep a healthy skin. On the other hand, by consuming it regularly constipation is avoided and by having it on an empty stomach it has a laxative effect.

In the daily diet it is necessary to consume a 10% of lipids, of which a major part should unsaturated fats, such as olive oil.

    9.- What happened with olive-pomace oil?

Background

On 3rd July, there was a press breakdown, informing about the preventive tying up of olive-pomace oils, to be subsequently withdrawn from the Spanish Market. This measure taken by Health and Consumption Ministry was communicated to the Autonomous Regions through the Food Alerts Net.

This measure took place in the usual frame of food alerts without having been verified or expecting in any way the appearance of intoxication in the citizens.

According to the Health Ministry, the alert was caused by the detection of a compound called alpha- benzopirene in some samples of olive-pomace oil in the course of the analysis routinely carried by technicians from the Agriculture Ministry. The alpha-benzopirene is a polyciclic aromatic hydrocarbon, which can cause cancer if people are exposed for a long time and in important quantities. The results of these analysis, were later confirmed by the Health Institute Carlos III, of the Health Ministry.

Until this moment in the regulations about oils, the presence of this toxic compound is not covered among the natural components of the olive, so the proper performance if the removal of a product which does not fulfil the corresponding regulations.

        9.1- What is the olive-pomace oil?

Olive-pomace oil is obtained form a treatment of olive pomace with an authorised solvent. Refined olive-pomace oil is obtained by refining of olive-pomace oils. The mixtures of refined olive-pomace oil and virgin olive oil are called refined olive-pomace oil and olive oil.

The olive-pomace is a by-product of the olive after being pressed several times in the olive oil mill to extract the oil. It is usually formed by rests of pits, skin, pulp, water, etc. This refuse is treated with solvents (ethilene chloride and exano) to extract the oil that still remains in this paste. Afterwards oil is heated to evaporate the solvents. These processes result in crude olive-pomace oil. Then it undergoes a refining process to eliminate impurities and substances, which produce a defective flavour. They use soda, high temperatures, deodorants and bleaching. After obtaining refined olive-pomace oil

It is mixed with virgin olive oil (in a proportion of 90/10 or 80/20) and olive- pomace oil is obtained. This oil is suitable for human consumption, with a worse culinary, nutritional and organoleptic quality than olive oil, but in principle with a correct hygienic quality and cheaper than olive oil.

        9.2- Why has the toxic substance appeared?

The cause of the appearance of alpha-benzopirene, is due to the change in the making process of these oils with the recent introduction in Spain of a new technology in the process of treatment of the refuse. With this new technology it is pretended to avoid the environmental problems of the alpechin which is a pollutant watery residue originated by the processes of transformation of the olive into oil.

Traditionally, to extract water from the refuse paste pressing processes and heating processes are alternated but to avoid the production of alpechin, new technology dehydrates the refuse paste with successive heating at high temperatures which produce the appearance of these toxins. Once the refuse paste has been dehydrated, the oil where the toxic product remains is extracted.

Olive-pomace oil producers have been involuntarily affected by this problem, as it was a completely unknown effect coming from the new technology. Likewise, this crisis has also affected olive oil and virgin olive oil market.

        9.3.- Present state of the crisis?

As it has happened in other occasions, a health problem acquires an out of proportion importance due to the economical and marketing interests and the alarmist performance of press.

Olive-pomace oil was withdrawn from the market on 3rd July. The following day Public Health General Manager (Dolores Flores) and the Food Safety Deputy Director (Ignacio Arranz) called us, as members of the Consumers and Users Board, in order to inform us about the reasons of the measure. From CECU we consider that the government performance was right and positive as well as the promptness with consumers were informed.

On 11th July, we took part on the meeting of the Interministerial Commission for the Food Organisation where the project of Ministerial Order, establishing the limits of some polyciclical aromatic hydrocarbons in olive-pomace oils.

Later, and with the consensus of all sectors, the Ministerial Order was passed. The aforementioned Order, establishes the maximum limit for the benzopireno in 2 micrograms per kg of product and 5 micrograms for the whole aromatic polyciclic hidrocarbons which olive-pomace oil can contain.

On 14th September olive-pomace oil was marketed again. According to the Minister of Agriculture, Mr Arias Cañete: once the regulation has been established producers have been able to fulfil it.

    10.- Conclusion

Nowadays we find in the market the same products than before the crisis but we have gone one step forward in alimentary safety. Consumers, despite being reluctant at the beginning, can now be safer.

    11.- How does olive-pomace oil crisis affect olive oil?

The crisis caused by pomace oil last July has not had negative effects on olive oil. Although at first there were several countries which eliminated Spanish olive oil from their markets, and even in Spain there was a decrease in the demand, finally the pomace oil crisis has even turned into positive results for olive oil. Pomace oil demand (around 6,000 tonnes per month in the domestic market) was partially deviated to the olive oil.

According to the data handled by the administration, during the first nine months of campaign 775,600 tones of olive oil have been marketed, a 16.6% more than in the same period, during the previous campaign, which means an average of 86,000 tones per month. 40,000 tones out of this figure correspond to exportations.

An important datum which is highlighted in administration, is the strong growth in sales of virgin olive oil, although their volumes are still low. From the total olive oil consumed in Spain, only 20% is virgin meanwhile 8% remaining is olive oil.

The expected production for the next campaign will raise up to about a million tones. This will provoke, as it happened this year, to lower the financial help of 220 pesetas/kilo to around 155 pesetas. When reaching 760,027 tones.

This data confirm that the consumer did not know much about olive oil before the crisis. Until that moment people used to confuse olive-pomace oil and olive oil, although extra virgin olive oil was supposed to have a better quality. After the crisis the consumer is better informed. But it is not enough. We demand more information so that the campaigns are as helpful as possible.

To this respect, CECU this the aim of informing to the consumers, sent a letter to their associated in the different Autonomous Regions to explain what has happened and to clarify the concepts, always trying to promote the consumption of olive oil, and especially extra virgin olive oil.

With this aim, we update our web-site about alimentary safety, explaining the elaboration processes of the different olive oils and the differences among them.

    12.- Consumers notion of olive oil

All in all, consumers are the aim of all the food and agriculture industry and our exigencies must be considered not only as buyers of different products, but also as receptors of the benefits or prejudices that the consumption of that product may provide, for us and our environment.

That is to say, consumers demand that the productive and commercial strategies of olive oil consider us from the beginning of the food chain and not at the end as they have done until this moment.

Nowadays, consumers are not mere buyers. The great variety of food oils, that we can find in the market, make our election to depend not only on cooking and nutritive needs of that food, but also on health and quality guaranties, such as the nutrient contribution, cooking tradition, organoleptic features and advantages in the use, that along with a more tight price, offer the different brands for the same product.

Normally, all consumers know, o should know, that our society offers a series of guaranties gathered in our legal code:

In the frame of the Spanish Constitution, article 51, states that the public powers guarantee the defence of Consumers and Users, protecting, by means of efficient processes, their safety, health and legitimate economic interests. In section 2 in this article it states that information and education will be provided for consumers and users and it will support their organisations.

This guarantee is developed in the General Law for the Defence of Consumers and Users (Law 26/1984, 19th July). In its article II, about the protection of health and security, states that products, activities and services presented in the market for the consumers will not imply any risk for their health or safety.

On the other hand, the Royal Decree 1945/83, by which infractions and sanctions in the area of consumers defence and food and agricultural production are regulated, implies a consideration of the present technical, economic and social conditions which surround products and services provided for consumers and users and which demand a clear delimitation of obligations and responsibilities to avoid individual or collective defencelessness before fraud, adulteration, abuse or negligence.

This RD is almost abolished, but the initial spirit prevails in the defence of consumers.

Likewise, the Spanish Food Code (Decree 2484/1967, 21st September) and the Technical and sanitary Regulations and Quality regulations of food products guarantee the specific aspects that this law offers, relating to food safety.

Olive oil, like most food, have their own European regulation (Regulation 2472/97) and Spanish (RTS of eatable vegetable oils, RD 308/1983, 25 January and its modifications, establishing the regulations for obtaining, elaboration, industrialisation and commercialisation of eatable oils with vegetal origin apart form other legal requirements).

All this normative frame, along with many other specific regulations relating to quality, hygiene, labelling, inspection, self-control, etc., is due to the spirit of safety that prevails in the European Union and which is recently being reinforced with the publication of the white book of Alimentary Safety and by the creation of the European Authority of Alimentary Safety, which once again is reflected in the creation of the Spanish Alimentary Agency.

But despite this, the consumer is now sceptic in part as a result of the growing globalisation of markets that he does not control, and also due to the disordered information that he receives. Another reason is because the recent crisis have made that the information he receives is precisely that which has not worked in the safety mechanisms.

Despite this, consumers are aware that “0 risk” does not exist and that nowadays we enjoy good safety levels in our products.

In Spain, consumers have an advantage relating to food: the Mediterranean Diet, whose main representative is the Olive Oil.

From some years now, the Mediterranean diet stopped being fashionable, trend to which consumers are susceptible. Even the use of different oils, other than olive, was advised as a paradigm of health. Fortunately, during the last years it has been clearly stated that olive oil is essential for our diet, and that its substitutes do not have the same properties and virtues.

The Spanish consumer prefer olive oil for house use mainly because he knows that it is the best one that he can consume and because he is not willing to change his healthy habits. But to be able to consume this product, we need to feel safe and that is why we submit our demands to the administrations, producers and dealers.


Consumers demands to olive oil producers.

That is why, consumers are more and more exigent in our demands. We demand safety, quality, information, transparency, training and price.

Ø Safety

The normative frame that we have referred to, where administrative controls and obligatory self-control in industries are reflected, along with the policies of integral quality in the companies, must guarantee safety for all olive oil, which is marketed. But we know that this does not always work as it should:

· We sense that the administration does not develop all the necessary controls to detect frauds. For example: The agricultural authorities in the control of pesticides; sanitary authorities in the control of elaboration in olive-oil mills, commercialisation, labelling...

· Companies outweigh the economic and technologic interests, in some cases even over the safety and nutritional values. For example: mixing of oils, use of low quality oils in restaurants...

· Alimentary technology, which advances quickly, does not disclose the damaging effects for consumers health. Ex. The refining treatments, the excessive heating that might produce toxic elements such as benzopirenes

 

Of course, we know that there are companies that offer all the demandable guarantees protected by a quality brand.

Ø Quality

Nowadays, the concept of “quality” is understood as the degree of satisfaction showed by the consumer, that is to say, the capability to respond to the demands, either explicit or implicit, of the consumer towards a product. But this concept has different aspects. It is necessary to take into account the hygienic quality, technological quality, nutritional quality, organoleptic quality, the care for the environment and even the price.

Olive oil producers have already established integral quality systems in their companies. In these systems is included the hygienic quality represented by the self-control systems based on the APPCC imposed by the administrations. But also they are certifying in quality systems based in international ISO, EN (European) and UNE (Spanish), and accrediting through well known accrediting bodies.

The most exigent protect their brands and ways of elaborating through guarantee of quality: DOP, IGP, ETG, Ecological Agriculture...

The consumer wants to know all these quality measures and also to which are the brands that offer them and those which do not. And which price is to be paid for that.

Ø Information

The more information consumers have the more they want. We demand safety, but we also demand to feel safe, and so we need to have objective and truthful information.

Now we know that if our life expectancy is higher than that in other countries around us is in a great part due to our diet and to the consumption of olive oil.

Well, we know this, but, is the same all the olive oil that we find in the market? Has it the same preventive properties that we know? The answer is NO. But this is what the consumer mistakes.

So the first demand of the consumers is information to be able to choose freely that which is better for us.

For example, in general, we do not know, that extra virgin olive oil is the one which joins all the excellence of this product. That the so called “olive oil” suffers a process of refining, which reduces the properties or that other oils coming also from olives (such as that of pomace olive oil) have not anything to do with virgin olive oil.

It is also very common the error of thinking that an oil with a higher grading is better or more pure that the one with a lower grading.

That is why, we ask the producers to give information by means of clear and transparent publicity campaigns.

Regarding to labelling, we have observed that in general it is correct in the oils that we find in the market. But not in products containing fats or oils in their composition. For example the mention of “vegetable fats” without specifying which type of fat is it, because it might have a vegetal origin such as coconut, palm or palm leaf and however they do not count on the features in unsaturated oily acids and their benefits, although we might think so.

Ø Transparency

Transparency is a demand directed in one hand to the administration and on the other hand to the producers.

To the administration we demand transparency in the crisis that affect food, in quality researches and in the results of the controls. That the quality data recognised by the administration in companies, are public.

To the producers we demand responsibility and quality.

Ø Training

Nowadays, society claims for training in the wide sense. Sanitary and alimentary training is also necessary. Form children at school, housewives, old people, the different collectives (affected by chronicle diseases, sportsmen, workers...). It is necessary education in healthy habits of life and specially in nutritive and technological values of our food. So that when the information that we demand arrive, it arrives in an already prepared field.

To this purpose, it might be interesting to intensify the information campaigns about olive oil, as we are trying to promote one of he most healthy and delicious tradition of our culture and at the same time we impulse our products...

To this respect, form CECU we are aware, that the Consumer Associations have a an important role in society. From this point of view, we are critical and active elements in training, information, denunciation and demand of satisfaction of the consumers.

This is why we ant to transmit the necessity that our voice is listened by all the implied sectors in the alimentary chain, because we should not forget that: We are all consumers
