| Objectives | To assess three edible species of plant from Australian sub-antarctic islands for their suitability for introduction to the fresh vegetable market |
| Background | After the discovery by the Royal Navy in the 18th century of the role of fresh fruit and vegetables in the prevention of scurvy, sailors in southern oceans used to visit a number of small islands in the sub-Antarctic to replenish their supplies of leafy green vegetables. Plants used included the Kerguelen Cabbage (Pringlea antiscorbutica) and the Macquarie Cabbage (Stilbocarpa polaris). In recent times researchers based on Macquarie Island have also regularly consumed a cress like plant, Callitriche antarctica. |
| Research | Three key issues have been investigated. These include prospects for acclimatisation and mass production, sensory analysis to judge consumer reaction to the ‘new’ products, and chemical analysis of their nutritional value. |
| Outcomes | Pringlea antiscorbutica seed
germinates easily at ca. 20° C and stratification
at lower temperature accelerates germination. The optimum growth temperature
is probably between 13 and 17° C. It could
be grown as either a sprout crop or a leafy vegetable crop and is most
likely to be used as a garnish. It can be consumed either raw or cooked.
It is visually appealing to consumers and scores highly for taste. It contains
high levels of potassium, and useful levels of carotenoids. It also contains
high levels of vitamin C, even when cooked.
Stilbocarpa polaris is easily propagated by rhizome cuttings but grows very slowly. It requires temperatures below about 20° C. It must be cooked to make it palatable and has less visual appeal than the other species. It scores well for taste, but less well for texture. It has higher starch content than the other species, but lower vitamin content. |
| Implications | Pringlea antiscorbutica has significant potential and deserves further investigation, including field growth trials in a cool location, and toxicological studies. Its main use will be as a garnish. Callitriche antarctica despite its attractiveness as a food crop it would be unwise to introduce this plant because of its high potential to become an environmental weed. It should however be further investigated for potential pharmaceutical uses. Stilbocarpa polaris grows too slowly to be commercially practicable. Despite having a pleasant flavour it is less visually appealing than the other species. No further work is recommended at present. |

| Objectives | To assess the current and preferred image for the Australian bushfood (native food) industry and to contribute towards an industry strategy to align efforts in addressing the image change and determining future marketing directions. |
| Background | The bushfood (native food) industry
covers plant and animal products which are derived from Australian indigenous
species. The main focus in this report is on the plant products. The bushfood
(native food) industry is now at a hiatus needing a uniform and firm image
and positioning. Several species are in oversupply and concerns exist from
the impact of recent product and company disappearances. Some growers are
already facing inadequate markets for their products. Cottage users cannot
absorb the excess product nor can specialty manufacturers. The current
bushfood (native food) range is also unsuitable for the fresh fruit market
due to the fast ripening times (short shelf-life) and the intensity of
taste in most of the products. There is obviously the problem of lack of
knowledge of use as well.
Demand must expand to the middle market with some urgency and mainstream products established before the Olympics, which provides a strategic link to continued overseas expansion. As identified in RIRDC Research Report No 97/22 and also in the Victorian Food Industry’s Indigenous Food Processing Feasibility Study 1999, the determination of the current perception of bushfood (native food) and re-positioning as necessary, is crucial to developing successful marketing strategies. This study focused upon the two markets of food service and manufacturers, which are the volume areas for short to medium returns and building these markets, indirectly addresses the more difficult (and expensive) task of educating the general consumer. |
| Research | The current status of native foods
was assessed amongst influencer (chefs and food media) and consumer groups
using interviews. Additionally, native food industry members and chefs
were surveyed for their input on status and preferred industry directions.
The individual in-depth interviews were conducted by either telephone or face-to-face and interviewees included leading chefs in both Sydney and Melbourne grouped as user or non-users of native ingredients. Additionally, equal numbers of food media in these cities were interviewed. Stimulus inputs used in the groups included ranges of packs of foods with bush ingredients (teas, relishes, sauces, juices, biscuits etc), pictures of dishes containing native ingredients along with a descriptive name for the dish, books, category descriptors, potential product concepts and positioning concepts. |
| Outcomes | The overall outcome of the research
is encouraging: All the indications are that native ingredients have considerably
more market potential if appropriate strategies are used.
2. Native foods are also thought to have the capacity to bring another dimension, an exciting and unique Australian flavour to the country’s rapidly evolving cuisine.
|
| Implications | The industry should actively reposition the category to a contemporary, prestigious, stylish, innovative and proudly Australian collection of unique, interesting, easy to use, clean, green and healthy flavours. Tools available include State and National instrumentalities and allied food associations and the regional and specific food programs they promote. The industry should support the formation of a peak body of representatives of associations and major value-adders. Over and above these is the influence for change, which can be exerted by individuals through their own purchasing power, with their own industry and future at heart. Through some strong cohesive actions, this uniquely Australian industry has the ability to become a significant force in the Australian food scene both here and overseas. |

| Objectives | To minimise quality loss and add value to culinary herbs and fresh herb products by developing optimum postharvest protocols and new modified atmosphere packaging systems. |
| Background | An earlier RIRDC project No. DAV-89A (Postharvest Handling and Packaging of Fresh Herbs. A review.) identified that there was little information available and little industry knowledge of the proper postharvest handling practices for fresh culinary herbs. In particular, there was considerable confusion as to how to package herbs. |
| Research | The optimum storage environment including CO2 and O2 levels and temperature, was identified for seven major culinary herb crops. These were basil, chervil, continental parsley, coriander, mibuna, mizuna, rocket and supreme cress. A number of packaging systems were then tested to identify the best packages available and to gather information on existing packaging systems. The research results were then used to develop a generic, optimum postharvest handling and packaging protocol for fresh herbs. |
| Outcomes | Storage at the correct temperature
increased the shelf life of all herbs substantially. Storage at 3oC
to 4oC rather than 8oC (which is a common storage
and retail display temperature) increased the storage and shelf life of
some herbs by nearly 50%. Modified atmosphere packaging increased the storage
life of most herbs under both temperature regimes. Some of the information
generated by this project is in use by industry with one company exporting
substantial volumes of fresh herb products.
Industry interest in the project is high with many requests for information and two contract research projects are currently under negotiation |
| Implications | This project has shown that the use of a good handling and packaging protocol can increase the storage life of herbs substantially compared to existing practices. Consequently, wastage will be reduced and new market opportunities can be developed. |

| Objectives |
|
| Background | In October 1997 the Far North
Queensland Longan Growers Assoc Inc recognised the need for more research
into longans and the subsequent funding requirements.
To achieve this a research levy was proposed but a prerequisite both of Government and the QFVG for such a levy was a Strategic Plan. |
| Research | The strategic plan was developed
by calling a meeting involving growers from all over Queensland and northern
New South Wales. The meeting was attended by 32 people including growers
and QDPI and CSIRO scientists.
Prior to the meeting a prioritisation worksheet allowing the ranking and suggestion of issues was sent out to all longan growers to aid the facilitator in carrying out the workshop. Introductory technical information concerning the research need: There was no single document or policy setting out the problems of the industry and preferred future directions. |
| Outcomes | The longan industry now has a plan it can follow and has been used by funding organisations in deciding upon research. Unfortunately priorities established within that strategic plan by the industry itself have not always been recognised and accepted by funding bodies reducing the value of the plan. |
| Implications | There is no doubt that growers,
particularly those away from the major growing areas, have found the Plan
useful background information to their management decisions.
The benefits to Far North Queensland Longan Growers Association, who in effect represent the Australian industry through Queensland wide membership, have been to accurately identify future actions at an industry level. This can be done in the knowledge that it has the consensus of the major proportion of the industry. The cost to achieve this has been relatively small. |

| Objectives |
|
| Background | Previous research identified limited market opportunities for hemp fibre as textiles, but did not consider other bast fibres such as kenaf, flax and the residues of sugar cane or cereal straw. |
| Research | This report presents an overview of the production, harvesting and processing systems involved in the supply of non-wood fibres from bast crops and from agricultural residues. The market opportunities for those fibres are analysed in terms of their physical characteristics, and their delivered cost as a raw material for different manufacturing industries. |
| Outcomes | There are few opportunities to
grow bast fibres or to utilise agricultural residues for pulping because
agricultural fibre yields are lower than wood fibre yields from forestry;
because the collection costs are high and small regional pulping mills
cannot not compete with large wood pulping mills.
Although it may appear economically viable to manufacture panel board from straw, a new venture is unlikely to succeed, because two major companies dominate the local market in which there is excess capacity. There are significant opportunities for bast fibres to be used in the manufacture of non-woven industrial textiles, particularly for insulation materials (replacing fibreglass batts) and automotive interior textiles, such as door panels and floor mats. Kenaf would be the most economical fibre to produce for non-woven applications, because of its high growth rate. The dryland conditions in Australia are ideally suited to the production of the un-retted fibre which is utilised in these products. The market for composite materials is in its infancy, and requires detailed study. The automotive market is the furthest advanced and has a particular interest in bast fibres because of their biodegradability. There may be a small business opportunity in the production of hemp oil seed for nutrition, cosmetic and pharmaceutical applications. |
| Implications | Opportunities for bast fibres
to be used non-woven industrial textiles should be further explored focusing
on insulation and automotive products, and fibre-reinforced composite materials.
Developments in bast fibre retting technology should be monitored and assessed, to determine their potential to deliver a competitive advantage to Australia. Key requirements are the production extremely high quality fibre, with low water usage and minimal impact on the environment. |
| Project Title | A field evaluation of the productivity of hazelnut varieties |

| Objectives |
|
| Background | The nuts of the hazelnut tree
(Corylus avelana) are roundish in shape and contain a highly nutritious
kernel. Australia imports approximately 1800 tonnes of kernels per year
with a total value of nearly $A10 million. Although hazelnuts were introduced
into Australia more than 100 years ago, this crop is only grown in a very
small way. Many varieties have been imported into Australia in the last
decade, but there has been no systematic evaluation of these. This research
is designed to assess these imported varieties compared with Australian
seedling types.
Hazelnut trees are cross pollinated. The pollen shed by the male catkins is blown through the orchard and trapped by the small female flowers as it drifts, so timing of pollen shed and female bloom between genetically compatible varieties is critical for effective pollination and nut production. |
| Research | Varietal trials have been established
at four centres, two in NSW (Orange and Moss Vale) and two in Victoria
(Myrtleford and Toolangi). The sites have been selected to evaluate the
varieties under differing climatic conditions. The sites at Orange and
Toolangi were planted in 1995, those at Myrtleford and Moss Vale in 1996.
The trees are now well established and starting to produce nuts.
Automatic weather-recording equipment has been installed at each site to monitor weather conditions and assess the effects of them on growth and production. Measurements are being made of tree growth and the period of flowering for each variety. When the trees produce nuts, yields and kernel quality will be assessed. |
| Outcomes | The periods when pollen is shed
and female flowers are open has been recorded at Orange. Some varieties
were found to shed pollen much earlier than others. In nearly all varieties
pollen shed commenced before the female flowers opened. A chilling period
(temperatures in the range 0oC-7oC) is needed to
trigger pollen shed and female bloom. There were differences between sites
in the amount of chilling the trees received in winter which may have implications
for varietal selection.
A few nut samples have been obtained at Orange in the summer of 1998. These samples, with data on periods of pollen shed and female bloom, are being used to describe and assess the varieties. |
| Implications | As the trees are only just coming
into production, limited data on varietal performance has been obtained
so far.
The trials need to be conducted for at least another 4 years to obtain data on varietal performance. |
