Η παρούσα πτυχιακή εργασία έχει ως αντικείμενο μελέτης τη διερεύνηση των παραγόντων που αποτελούν την επιλογή των κριτηρίων της χώρας εξαγωγής του βιολογικού ελαιολάδου. Στόχος είναι να εξετάσουμε την πορεία του βιολογικού ελαιολάδου κατά τη διάρκεια των χρόνων, λαμβάνοντας υπόψη μας τις παραμέτρους που βοήθησαν ή αποτέλεσαν ανασταλτικό παράγοντα όσον αφορά την επιλογή τόπου, χρόνου και χώρας εξαγωγής. / The present paper studies all the factors that combine to make somebody choose the country to export bio olive oil. Our goal is to define the exact evolution of bio olive oil exports throughout the years, taking into account all the circumstances that boosted them or opposed to them, depending on the place, time and country of export.

Olive oil production in Australia has increased significantly in the past decade, and will soon reach about forty thousand tonnes per annum. While some Mediterranean countries have well established, modern olive oil industries, the Australian industry is still in its infancy. In order to compete in the world market, the Australian olive oil industry requires information on the response of olive cultivars in Australian conditions, especially when to harvest and irrigate to produce high quality olive oil. This study investigated the effect of harvest timing and irrigation on the quality of olive oil. It was conducted on a commercial olive grove in southern New South Wales over a three year period. It involved harvesting, extraction and analysis of the oil at 6 harvest times from early February to late July. A number of irrigation regimes were imposed in this study, although management was difficult due to drought conditions and lack of available water. The study provides very useful information and guidelines not only for the Australian olive industry, but also for the international olive oil producing community. / Master of Science (Hons)

Presently in South Africa there exists a rising demand for olive oil. Within the context of increased imports, increased distribution and the introduction of different product lines of olive oil by large retailers this exploratory study investigates the consumer profile of olive oil consumers in Durban, KwaZulu Natal. The demographic variables of age, gender, income and educational level amongst Durban consumers were considered. To properly understand the olive oil purchase decisions, the aspects of consumer psychology that were considered included exposure to olive oil, preferences for types of olive oil, perception and memory recall. These psychological aspects were considered in the context of the afore-mentioned socio-demographic variables. A quantitative approach was used in this study. One hundred respondents were interviewed using the mall intercept method. Respondents answered a self-administered questionnaire which consisted of 18 questions that captured the objectives of the study. The generated data was analysed using statistical software and specifically the statistical techniques of cross tabulation and chi-square test of independence. The data attested to the fact that there was indeed a relationship between age, gender, income and educational levels amongst Durban consumers which answered the first research objective. The second research objective involved investigating the reasons for purchase and non-purchase of olive oil amongst Durban consumers. Sixty eight percent of the non-purchasers were reluctant to purchase the olive oil because of pricing issues with thirteen citing supply or availability issues. The most popular reason for purchasing olive oil was because of its health benefits followed by taste. The study also showed that the KZN market felt that insufficient exposure was given to olive oil. The typical olive oil consumer in Durban is likely to be aged between 45 to 54 years old, a female with a tertiary education and an income level between R7429 - R13 787. The study provided the broad parameters of a Durban olive oil consumer as well as his psychological purchase decision factors to enable olive oil marketers to better solidify the existing market whilst penetrating newer markets both within and beyond KwaZulu-Natal. / Thesis (MBA)-University of Natal, Durban, 2003.

La culture de l’olivier et la production d’huile, du Néolithique à l’Empire romain : le cas particulier de la péninsule Ibérique. Ce titre met en lumière les deux axes principaux de cette recherche doctorale. La première concerne la domestication de la plante à partir des zones refuges de l’oléastre en Méditerranée ; la deuxième, l’apparition des différentes technologies de production oléicole, leur évolution, ainsi que les héritages observés entre les différents peuples du Bassin entre le Néolithique et l’Empire romain. Toutes ces problématiques sont analysées à partir du cas précis de la péninsule Ibérique, extrémité occidentale de la Méditerranée, lieu d’échanges et d’influences d’origine orientale – phéniciennes et grecques, principalement. Grâce à l’étude de la domestication et des premières implantations de l’olivier il a pu être mis en évidence la nécessité d’associer l’archéobotanique – identification d’endocarpes, du charbon de bois et du pollen – à la génétique. Cette dernière a récemment permis de démontrer l’autochtonie de la plante en Méditerranée occidentale depuis les dernières glaciations, contestant ainsi les théories diffusionnistes d’une origine phénicienne – exclusivement orientale – de l’espèce et de l’oléiculture. La deuxième partie consacrée à l’étude de la technologie oléicole péninsulaire, démontre l’importance d’une machinerie de type artisanal et local, contemporaine d’une mécanique de type « préindustrielle » d’origine orientale. Les deux groupes typologiques se complètent et s’influencent jusqu’à l’arrivée de l’industrie oléicole romaine. / The culture of olive tree and the production of olive oil from the Neolithic Era to the Roman Empire: the case of the Iberian Peninsula. The title highlights the two main research lines of this doctoral thesis. On the one hand, the domestication of the olive plant from the refuge areas of oleaster in the Mediterranean Sea; on the second hand, the emergence of different technologies of oil production, evolution and legacy observed between the different cultures of the Mediterranean from the Neolithic Era to the Roman Empire. All these issues are studied within the specific context of the Iberian Peninsula, western end of the Mediterranean world and place of exchanges and influences of from Eastern cultures - namely Phoenician and Greek. Through the study of domestication and first implantations of the olive tree emerged the need of involving scientific research from archaeobotany - identification of endocarps, wood charcoal and pollen - to genetics. The latter has recently demonstrated the indigeneity of the plant in West Mediterranean since the last glaciations, thus disputing the “diffusionist” theories of a Phoenician origin - exclusively Eastern - of the varieties of olive and their production. The second part of the research, dedicated to the study the Peninsular technology of olive oil, demonstrates the importance of craft and local machinery, as well as contemporary ‘preindustrial’ types of Eastern origin. Both typological groups complement and influence each other until the introduction of Roman olive industry.

The research within this thesis sought to determine the ability of various animal derived fats and plant derived oils to support the survival of several pathogenic cocktails over a multitude of storage times. The Salmonella study explored the survival rate of a four strain Salmonella cocktail in beef tallow, pig lard, duck fat, coconut oil, and extra virgin olive oil over seven days at 26˚C and 37˚C storage. The animal fats and the coconut oil supported the survival of the bacteria until the conclusion of the study. The Shiga-toxin producing Escherichia coli study explored the survival rate of a five strain STECs cocktail in extra virgin olive oil over seven days at 26˚C and 37˚C storage. The two Listeria studies explored the survival rate of a four strain Listeria monocytogenes cocktail in extra virgin olive oil over several time periods with different frequencies of sample mixing. In vitro, all genuses showed a 2.5-log cfu/mL to ≥ 7-log cfu/mL reduction in the extra virgin olive oil by the conclusion of the experiments. Extra virgin olive oil was then applied to cooked pork tenderloin, cheddar cheese snack squares, and turkey lunchmeat in hopes of inhibiting the L. monocytogenes cocktail. No reduction was observed.
