Bioremediation and biovalorisation of olive-mill wastes
No full textOlive-mill wastes are produced by the industry of olive oil production, which is a very important economic activity, particularly for Spain, Italy and Greece, leading to a large environmental problem of current concern in the Mediterranean basin. There is as yet no accepted treatment method for all the wastes generated during olive oil production, mainly due to technical and economical limitations but also the scattered nature of olive mills across the Mediterranean basin. The production of virgin olive oil is expanding worldwide, which will lead to even larger amounts of olive-mill waste, unless new treatment and valorisation technologies are devised. These are encouraged by the trend of current environmental policies, which favour protocols that include valorisation of the waste. This makes biological treatments of particular interest. Thus, research into different biodegradation options for olive-mill wastes and the development of new bioremediation technologies and/or strategies, as well as the valorisation of microbial biotechnology, are all currently needed. This review, whilst presenting a general overview, focus critically on the most significant recent advances in the various types of biological treatments, the bioremediation technology most commonly applied and the valorisation options, which together will form the pillar for future developments within this fiel
Exploring Japanese olive oil consumer behavior
No full textDuring the last two decades, olive oil consumption in Japan is showing an increasing trend due to dietary and health concerns. Traditional olive oil producer and exporter countries such as Italy, Spain and Tunisia have interest to reinforce and to increase their penetration in the Japanese market. This study examines Japanese olive oil consumer behaviour by the use of the conjoint analysis technique. Five attributes have been chosen to design the experiment: region of origin, price, olive oil type, taste and colour. Two models have been estimated where the price variable was introduced in its discrete form in the first model and in its linear and quadratic from in the second model. In a second step, consumer segmentation was undertaken based on consumption frequencies. Two groups have been identified: “heavy consumers” and “light or potential consumers”. The main results indicate the importance of the selected variables in Japanese olive oil consumer' choice. Olive oil with Mediterranean or Tunisian origin has higher probabilities to be chosen than Italian or Spanish one. Japanese consumers prefer a green with bland taste olive oil. Concerning olive oil type, results indicate that refined olive oil has more probability to be chosen than virgin or extra-virgin one, indicating low awareness of Japanese consumers about olive oil. The price variable estimates have shown a convex utility curve indicating a decrease of consumers’ utility when price increases till a maximum price. Above that price, consumers’ utility increase indicating in that case that olive oil is considered as a luxurious product. Differences as well as similarities have been detected among consumer segments.Olive oil, Japan, consumer behavior, Consumer/Household Economics,
An investigation into the bioremediation of black olive brine wastewater
No full textIn South Africa, the table olive industry is burgeoning and as a consequence, the large volume of fermentation wastewaters that are generated have created environmental concerns, as these wastewaters have the potential to pollute rivers and ground waters. Currently, these wastewaters are disposed of in large evaporation ponds, but this is not considered to be the optimal treatment solution, due to the potential for pollution and environmental damage. This thesis describes an investigation into the bioremediation of black olive fermentation wastewaters. Wastewaters, from both the table olive and olive oil industries, are toxic and this toxicity can be attributed to the phenolic compounds present. These compounds are known to have antimicrobial and phytotoxic effects. Aerobic biological treatments have been extensively investigated in order to reduce the phenolic fraction of olive mill wastewaters (OMW) with relative success. Biological treatment methods are also cheaper than chemical or physical treatment methods. Therefore, it was decided to investigate aerobic biodegradation of black olive fermentation wastewater (olive wastewater) from the production of black (Kalamata) olives
Adoption and diffusion of no tillage practices in Southern Spain olive groves
No full textThis paper analyses the process of adoption of no tillage in South-eastern Spain’s olive groves. Olive tree groves in South-eastern Spain’s mountainous areas are subject to a high risk of soil erosion, which is the main environmental problem for this crop, and have to incur in high costs of soil conservation. This results in a greater difficulty to comply with the practices required to benefit from both the single payment and agri-environmental schemes. In many high-steeped areas, farmers have opted for non-tillage practices as an alternative to other conservation practices. Using our own data from a survey carried out in 2006 among 215 olive tree farmers from the Granada Province in Southern Spain regarding the adoption of soil conservation and management practices, we model the diffusion process of no tillage practices using several specifications (logistic, Gompertz and exponential). We also estimate an ordered probit model to analyse which socio-economic and institutional factors determine the adoption of no tillage. Our results show that 90% of farmers in the area of study perform no tillage with either localized (21%) or no localized (69%) application of weedicides. The diffusion process of no tillage has been very intense since the middle nineties, and has been based on the interactions among farmers in the area of study rather than in external factors such as EU policies or extension services. Among other relevant factors that positively affect the adoption of no tillage practices in general, such as farm size and irrigation, the probability of a farmer adopting no tillage with non-localized application of weedicides increases when there is a relative that will continue with the farming activity, what causes the farmer to incorporate long term effects in his farming decisions, when the farmer is only a manager or when he bought the farm rather than inherited it (i.e. on more professionalized farms), and with his educational level. These results confirm some findings from previous studies in other nearby areas.Spanish olive groves, soil erosion, no tillage, Crop Production/Industries, Land Economics/Use,
The Greek Olive Oil Market Structure
No full textFood product differentiation leads to significant price variations among the same products, meaning that specific products can be sold in higher prices. An Hedonic Price analysis is adopted to investigate the influence of food differentiation on consumer prices and to identify product attributes’ values for the olive oil market. This will con- tribute to device the most appropriate olive oil differentiation strategies in order to be purchased by consumers in a higher price. The retail price structure was estimated in relation to several product natural attributes, to production and processing conditions, to quality control and to labeling and distribution. Findings demonstrate that olive oil price differentiation is mainly influenced by factors relevant to quality of life, purchase uncertainty, acquisition cost and consumers’ psychological needs. Additionally, vertical integration in production and processing and the retailer size significantly influence the olive oil price formulationdifferentiation structure, hedonic prices, olive oil market, Crop Production/Industries, Marketing, Q13, C23, L15, M31,
The water footprint of olives and olive oil in Spain
No full textThis paper evaluates the water footprint of Spanish olives and olive oil over the period 1997-2008. In particular, it analyses the three colour components of the water footprint: green (rainwater stored in the soil), blue (surface and groundwater) and grey (freshwater required to assimilate load of pollutants). Apparent water productivity and virtual water embedded in olive oil exports have also been studied. Results show more than 99.5% of the water footprint of one liter of bottled olive oil is related to the olive production, whereas less than 0.5% is due to the other components such as bottle, cap and label. Over the studied period, the green water footprint in absolute terms of Spanish olive oil production represents about 72% in rainfed systems and just 12% in irrigated olive orchards. Blue and grey water footprints represent 6% and 10% of the national water footprint, respectively. It is shown that olive production is concentrated in regions with the smallest water footprint per unit of product. However, the increase of groundwater consumption in the main olive producing region (Andalusia), from 98 to 378 Mm3 between 1997 and 2008, has added significant pressure in the upstream Guadalquivir basin. This raises questions about the sustainability of irrigated olive orchards for export from the region. Finally, the virtual water related to olive oil exports illustrate the importance of green water footprint of rainfed olives amounting to about 77% of the total virtual water exports
Biosensor immunoassay for traces of hazelnut protein in olive oil
No full textThe fraudulent addition of hazelnut oil to more expensive olive oil not only causes economical loss but may also result in problems for allergic individuals as they may inadvertently be exposed to potentially allergenic hazelnut proteins. To improve consumer safety, a rapid and sensitive direct biosensor immunoassay, based on a highly specific monoclonal antibody, was developed to detect the presence of hazelnut proteins in olive oils. The sample preparation was easy (extraction with buffer); the assay time was fast (4.5 min only) and the limit of detection was low (0.08 mug/g of hazelnut proteins in olive oil). Recoveries obtained with an olive oil mixed with different amounts of a hazelnut protein containing hazelnut oil varied between 93% and 109
Detection of Virgin Olive Oil Adulteration Using Low Field Unilateral NMR
No full textThe detection of adulteration in edible oils is a concern in the food industry, especially for the higher priced virgin olive oils. This article presents a low field unilateral nuclear magnetic resonance (NMR) method for the detection of the adulteration of virgin olive oil that can be performed through sealed bottles providing a non-destructive screening technique. Adulterations of an extra virgin olive oil with different percentages of sunflower oil and red palm oil were measured with a commercial unilateral instrument, the profile NMR-Mouse. The NMR signal was processed using a 2-dimensional Inverse Laplace transformation to analyze the transverse relaxation and self-diffusion behaviors of different oils. The obtained results demonstrated the feasibility of detecting adulterations of olive oil with percentages of at least 10% of sunflower and red palm oils
Market dynamics and policy reforms in the EU olive oil industry: An exploratory assessment
No full textAvailable information indicates that the future competitive scenario for EU olive oil will be shaped by the market dynamics and business strategies, and the ongoing agricultural and trade policy reforms (CAP reform, WTO Doha Round negotiations, regional and bilateral trade agreements). Based on this premise, the purpose of this contribution is to present an overall evaluation of the market change and policy reform processes affecting the EU olive oil sector, pointing out the main strengths, weaknesses, opportunities and threats (SWOT) that can be associated to their present and expected evolution. The analysis is performed with a systemic approach to market and policy changes, under the general hypothesis that these are governed by a series of economic and regulatory factors on which there is little empirical evidence or which still are subject of public debate whose outcomes are not clear. It is also assumed that while some of these factors act on a global level, others may vary across countries and even within countries amongst different players, which means that there is a wide spectrum of possible strategies and courses of action for the future. The information used is gathered through a combination of secondary sources and primary data from consultations with a representative group of key informants in olive oil policy and markets.Globalisation, market dynamics, business strategies, agricultural and trade policy reform, EU olive oil, SWOT analysis, Agribusiness,
