Evaluation of New Analytical Methods to Detect Lower Quality Olive Oils | AgriFutures Australia Evaluation of New Analytical Methods to Detect Lower Quality Olive Oils RIRDC Publication 12-007, June 2012 Author(s): Claudia Guillaume, Leandro Ravetti This RIRDC report provides information about the effect of exposure to oxygen, light and storage temperature on the quality of olive oil. Olive oil has been shown to quickly deteriorate when stored under less than ideal conditions. Sometimes growers produce oil with very high quality initially, which quickly deteriorates due to the conditions under which it is stored. The report is targeted at olive oil producers, transporters, warehouse operators, importers and exporters, retailers and consumers. It is important to be aware of the risks of improper storage on olive oil quality whether buying, selling, transporting or storing the product. Comments: This publication is current and relevant.

Sterols in Australian Olive Oils: The effects of technological and biological factors RIRDC Publication 10-173, October 2010 Author(s): Leandro Ravetti, Joshua Johnson, Claudia Guillaume Plant sterols have been found to be effective in lowering elevated cholesterol and are now being added to a wide range of foods. Ironically, international standards for olive oil set a low limit for phytosterols. Due to natural variations in oils from new growing areas such as Australia, some Australian oils have higher levels of phytosterols. The total content of sterols and their composition in olive oil seem to be influenced not only by genetic factors but also by management and processing techniques. The aim of the report was to improve processing and product quality while meeting national and international standards through supporting consistent production of high quality, healthy and safe olive oil that meets consumer expectations and in which they have confidence.

Harvest-timing, Sensory Analysis and Shelf Life for Optimal Olive Oil Quality RIRDC Publication 10-177, October 2010 Author(s): Rodney J. Mailer, Jamie Ayton Oil quantity and quality rely heavily on crop management, harvest timing, processing methodology and storage. In the initial stages of the development of this industry, there was little understanding of the intricacies of these crop management practices and the resultant crop yield, chemical quality and sensory attributes such as taste, colour and odour. For these reasons, this RIRDC study has been undertaken to look at the significance of irrigation treatments and harvest timing on oil quality, yield and sensory characteristics.

It is research that will be of interest to current industry participants, the olive research community and analytical laboratories. Frost is one of the most important weather related hazards for the Australian olive industry and has caused significant economic losses during the past decade. Its impact on oil quality has been significant in 2006 with more than 20 per cent of Australian oil of that year being affected to some degree. Early frosts will normally affect the fruit leading to significant changes in the chemical and organoleptic characteristics of the oils.

Download report: Olive water use and yield – monitoring the relationship | AgriFutures Australia Olive water use and yield – monitoring the relationship RIRDC Publication 03-048, September 2003 Author(s): Ian Nuberg, Isa Yunusa This publication presents a project that monitored the water use of trees across four mature groves in South Australia for two growing seasons. The aim of the project was to provide estimates of evapotranspiration during the growing season, characterise the relationship between water use and olive yield, and provide guidelines for efficient management of irrigation water for optimum yields. The report shows how grove management affects water use and that the irrigation regimes of the monitored groves were not optimal for olive yield. It shows the necessity of developing irrigation practices that prevent shortage of water during the middle of growing season in mid-summer, and which partition more of the evapotranspiration through the transpiration pathway to ensure high olive yield and water-use efficiency.

Olive Harvesting
Download report: Improving the Efficiency of Mechanical Olive Harvest: Evaluation of fruit loosening agents | AgriFutures Australia Improving the Efficiency of Mechanical Olive Harvest: Evaluation of fruit loosening agents RIRDC Publication 08-052, September 2008 Author(s): Leandro Ravetti and Brigid McClelland This RIRDC publication outlines the findings of a two-year trial evaluating the currently available fruit loosening agents employed under Australian conditions in order to determine their cost effectiveness and conditions for their commercial use. The forces that lead to mechanisation in agriculture are clear – high cost and availability of manual labour. For some crops, these economic forces have led to rapid adoption of mechanisation, for others, like olives in the Mediterranean basin the pressure for mechanisation has been growing at a much slower pace. This report will be useful for Australian olive growers and will provide supporting information to support registration with the APVMA to enable legitimate use of this chemical in Australian conditions.

Download report: Recycling Solid Waste from the Olive Oil Extraction Process | AgriFutures Australia Recycling Solid Waste from the Olive Oil Extraction Process RIRDC Publication 08-165, October 2008 Author(s): Assoc. N.G. Tan Nair, Julie Markham The report is about developing an environmentally sustainable system to manage solid waste from the 2- and 3-phase olive oil mill extraction processes. The Australian olive industry has been expanding at the rate of about 9% per annum over recent years. This significant increase in fruit production will result in vast quantities of solid and liquid wastes generated to the detriment of the environment. The industry is therefore faced with the challenge to manage these wastes in order to achieve sustainable production under a clean environment. The research was done over three years at three sites in New South Wales using olive husk waste collected from 2005, 2006 and 2007 harvests. The research work reported here is important because it provides the industry with a tool to recycle processed oil mill waste to improve the health of the crop and the status of the soil.

Mailer, Kerrie Graham This RIRDC report assesses the impact of storage in a range of flexible storage containers on extra virgin olive oil quality. The research was conducted by the Australian Oils Research Laboratory (AORL). It was supported by RIRDC and the Australian Olive Association. The outcome of this study reinforces that the best storage conditions for olive oil is in opaque, impervious and inert containers, stored at cool temperatures. Stainless steel or glass would appear to be the best options for long term storage. Metallised flexible bags used for short term transport may provide reasonable protection. Storage in clear plastic, particularly in the light and at elevated temperatures, is clearly unacceptable and will result in total loss of extra-virgin olive oil quality within weeks and perhaps days. Re-use of these containers would appear to be highly undesirable and would be expected to cause more rapid degradation.

Download report: National Olive Variety Assessment – Stage 2 | AgriFutures Australia National Olive Variety Assessment – Stage 2 RIRDC Publication 05-155, October 2005 Author(s): Susan Sweeney A major challenge in the establishment of the olive industry has been the selection of varieties best suited to Australian conditions, for optimal yields and quality. There has been limited reliable information and performance data for any olive variety under the wide range of Australian conditions and the industry has relied mainly on Northern hemisphere research and information. Another major issue that has confronted the Australian olive industry is that of ensuring the correct varietal identity of a particular tree, as there is a great deal of confusion in olive variety identification. Performance characteristics of a specific genotype are the basis on which a selection is made for a particular usage or physical situation. Correct identification at the time of tree purchase is therefore critical since mistakes may not become apparent for some years. The National Olive Variety Assessment (NOVA) project was established to help resolve the confusion in olive variety identity and to evaluate the performance, in different climatic regions of Australia, of the majority of known commercial olive varieties.

Download report: Olive Oil: Yield, Quality and Cultivar Identification | AgriFutures Australia Olive Oil: Yield, Quality and Cultivar Identification RIRDC Publication 01-023, March 2001 Author(s): Kevin Robards and Rod Mailer Olives were introduced to the Colony of New South Wales on 28th December 1800 by George Suttor, a London market gardener. Production never progressed beyond the cottage industry phase. Demand for olive products has increased dramatically in recent times due to higher incomes and interest in a healthy lifestyle. However, the demand is currently met by imports. Siting of the Wagga Wagga Agricultural Institute (WWAI) and Charles Sturt University (CSU) with an Olive Grove on CSU land was an integral feature of this project. Both agencies have been actively involved with the olive industry in the provision of technical advice to growers and use of the Olive Grove as a training facility. For example, during 1996 a workshop was organised under the auspices of the Australian Olive Association (AOA) at CSU. The workshop included sessions on horticulture, sensory evaluation and production of olives and olive oil. The lack of appreciation of oil quality and flavour was identified as a key issue confronting the Australian olive industry. Comments: This publication is now out of date. Relevant in the historic context of the industry 20 years ago. |

Download report: Wild olive selection for quality oil production | AgriFutures Australia Wild olive selection for quality oil production RIRDC Publication 00-116, August 2000 Author(s): UA-41A The olive (Olea europaea L.) is a small evergreen tree adapted to a Mediterranean climate. It yields two products, table olives and olive oil, both of which are important commodities on world markets. One of Australia’s first industries following European settlement was table olive and olive oil production, and many introductions of olive varieties were made from overseas. Despite this, the Australian olive industry went into decline and almost all olive products consumed are now imported. Olives are ideally suited to the southern Australian environment, as demonstrated by its status as an invasive weed, by natural seed propagation from the original introductions. The olive competes so well with native vegetation in disturbed sites, that eradication programs are underway throughout southern Australia in an attempt to preserve bushland areas. It is essential that superior wild material is identified and propagated before it is destroyed, as it represents the progeny of an uncontrolled outcrossing ‘experiment’. Based on this wild material, which is clearly well-adapted to Australia, there is the potential to increase Australian olive oil production, and so to replace imports of olive products currently valued at $100 million. More importantly, the industry intends to develop an export market in olive products, and this is increasingly likely following crop failures overseas. Improved planting material is needed for the industry renaissance. Comments: This publication is of historical value, Olives SA interested in maintaining this collection. Potential new project on heritage EVOO varieties. |
