Issue 1, March-Apri1 1997

NOTES

The cover plant this issue is Syzygium fibrosum (Rain cherry) - which is not the riberry. The Riberry is Syzygium leuhmannii. However, what most people call the Lilly pilly is in fact Acmena smithii.

Confused? Read on...

It's easy to imagine that the vast range of Lilly pillys are all Syzygiums of one sort or another but in fact the Lilly pilly proper is Acmena smithii. Many if not most of the twenty or so species of Syzygium are commonly called Lilly pilly and Acmena shares a number of features with this larger brood; they are small to medium sized trees with an ornamental habit, eye catching pink-purple leaf flush, a sweet to tart fruit, a moderate to fast growth rate and a good name for jams and jellies.

Acmena smithii is not on the 'top ten' list of bushfoods but a number of Syzygiums are being pursued with enthusiasm.

S. leuhmannii (the Riberry) is definitely flavour of the month (though some would say there are Syzygiums with a superior fruit).

Description

The Riberry grows naturally in an area from Kempsey in NSW to Cairns, Qld, usually found in littoral, riverine and subtropical rainforests. It will tolerate a wide range of soil types but seems to flourish in coastal areas. It is not an especially frost tolerant species.

The riberry can be slow to establish if it is not receiving adequate nutrients and moisture - flowering and fruiting can take anything between 2-6 years.

Fruit

The cream coloured flowers appear from September to February according to climate and aspect and harvest is between October and April.

There is usually one seed in the light pink to red fruits, which have a unique flavour and a definite acid 'tang'.

There is a large variability in flavour between trees.

Seedless varieties are now being avidly sought by growers and balancing taste/seedlessness/hardiness and yield is a challenge.

Propagation

As mentioned, the seedless variety is now actively sought after. Syzygium reproduces readily from seed but cutting grown (clonal) trees ensures genetic quality of the parent tree.

Grafting and top-working seedlings onto inferior stock is an area which needs research.

Tissue culturing may be the only way to meet existing demand for superior stock.

Planting/Yield

Minimum suggested size of planting to avoid inbreeding is 20-40 trees.

Greatest yield is obtained .from plantings in full sun and the heaviest fruiting will be on the sun side. It takes well to a light shaping prune after fruiting.

Larger, mature trees (40 years plus) can yield up to 60-70 kg of fruit (still leaving 20-40 in the inaccessible top halt) but a more realistic yield (at year 7) would be 12-16kg per tree pa.

Pests and Diseases

The Riberry appears relatively pest-free but has some susceptibility to scale pests

* soft brown scale (Coccus hesperidum)

* pink wax scale (Ceroplastes rubens)

The fruit fly (Dacus spp) is a potential pest.

Harvest/Post Harvest

Riberry is a 'soft' fruit and bruises easily. Harvesting by hand is predominant although some 'semi mechanised' methods may be in use (adaptations of grape or coffee harvesting machinery is a possibility). Immediate cold storage is necessary (5° for short duration storage). It can be transported in plastic bags insulated in polystyrene. It freezes well and drying is another option. It is a world class processing fruit and this, along with its unique taste, ensures a good commercial future.

What are Bushfoods?

VicVic Cherikoff

For some, bushfoods area culinary bridge between two cultures; for others they are strictly a crop; they are also on ideal form of 'semi commercial' revegetation, an environmental experiment, an exciting and uniquely Australian cuisine, a health food, a cuisine. In this issue, Vic Cherikoff gives a splendid overview of the industry.

Bushfoods:

The world depends upon eight plant species for the majority of its food supply. None of these is native to Australia. Our current food production methods are invariably biologically simple and are dependent upon artificial chemicals, major capital investment, etc. Bushfoods offer us an opportunity to diversify our food production systems.

At present, over 500 restaurants incorporate bushfoods in their menus. Bushfoods are featured in many airlines in-flight meals, on luxury cruise ships, in Parliament Houses, Australian Embassies overseas and many international hotel restaurants through Asia. There have also been minor incursions into the US and European markets.

The range of bushfoods selected by Bush Tucker Supply Aust. as commercial species is documented as having been or still being in use by the Aborigines as food, thus complying with the WHO/FAO definition for bushfoods as foodstuffs of a discrete population. This is relevant to future export markets if challenges are made as to whether the new products qualify as foodstuffs. However, toxicology issues will need to continue to be addressed, particularly with international regulations changing.

In the development of the bushfoods industry, education of potential growers, manufacturers, end users and government has been necessary. 

We have the opportunity knocking at our door We have to choose whether to open the door or move house. It means stepping into the unknown.

Growers have not had any previous experience to follow. For example; optimal plant densities, suitable selections, harvesting methods and post-harvest requirements have all had to be identified, tested and refined. Research is needed to determine the appropriate companion plantings for bushfood species and the practicality of mixed plantings for pest control and efficiency of harvest.

The bushfoods currently supplying the market come from a mix of some wild collections and, more significantly, harvests from organically grown species. There may be a new production classification.

Two could be applied. The first, native quality - refers to organically grown indigenous species harvested from mixed system plantings. A subgroup may become necessary if some species are organically grown in a monoculture system in an ecologically sustainable way.

The second classification is wild quality and two sub-groups may also be necessary here. One would apply to opportunistic wild harvesting and a second made to the regular collections made by Aboriginal communities

Vic Cherikoff has been credited with pioneering the development of the bushfood industry and a native Australian national cuisine. Through his commercialisation and promotion of a section of bushfood species for  innovative chefs, our native foods are now finding enthusiastic acceptance in Australia and around the world.

However, there are threats looming. Just as the Australian native macadamia nut is now known as the Hawaiian nut to most the world, many other Australian bushfoods are currently being researched as commercial crops by overseas workers.

These include quandong, desert limes, lillypillies and wattles. Desert honey ants are being evaluated for production in the US and Australia's competitive edge on the world emu market may already be lost.

Nevertheless, after years of ridicule or dismissal, the concept is now being discussed (and trialled). The final stage is widespread acceptance and use.

BTS Aust was the world's first bushfood distribution company. It not only had to develop supply lines, but test products, develop standards, create markets and educate customers with entirely new and innovative products.

Australian natural wild flavours.

Most of them are best applied in small amounts due to their flavour concentration.

For this reason, the range of bushfoods currently considered commercial is more akin to herbs than to conventional fruits or vegetables in their culinary use.

Bushfood production provides an opportunity to redress the shortcomings of conventional agriculture; windbreaks, shelter belts, buffer zones and home paddocks can include productive native species or can be used for on-farm foraging to supplement farm income.

There are many points to consider in growing native species for bushfood, including (but by no means exhaustively):

  • is the local species economic? (some bushfoods are good forage but may not be commercially significant.)
  • can a viable production system be based exclusively on native species?
  • what indicator plants give an indication of the local environmental features?.
  • what species are necessary for ecological sustainability?
  • what are efficient methods for harvesting?
  • what species are best to use as pioneer species?
  • how will future expansion be accommodated?
  • how densely can the plants be spaced?
  • where are your markets and how will these be developed?

The 36 bushfoods (in over 200 forms) distributed by Bush Tucker Supply Australia have been used by niche market gourmet food producers as wild flavours in ice-cream, biscuits, chocolate, pasta, smallgoods, preserves, sauces, chutneys, relishes, bread, cordial and tea. Supplies are now available in sufficient quantities for mainstream manufacturers of breads and herbal infusions to use them in a wide spectrum of processed products. Two supermarket lines are Goodman Fielder's Bush Breads of Australia and Bushell's native herbal range. A few bushfood companies have their products in Coles stores and there is much more to come this year. Post harvest quality standards within the bushfoods industry are being investigated in response to demands by manufacturers. Specifications for each bushfood ingredient have been produced to define quality, flavour strength, availability, applications, useage rates, storage recommendations, pack sizes and nutritional information. Continuous raw material development and refinement of purity is ongoing and microbiological assessment is conducted where necessary. The development of the Australian bushfoods industry is unique as few countries can offer such a range of indigenous foods. Domestically, the industry has little or no short-term competition, although, in the market place, bushfoods compete with other gourmet foodstuffs such as blueberries, wild rice etc.

The author of two books on bushfoods, "The Bushfood Handbook" and "Uniquely Australian", a wild food cookbook, Vic has spread his enthusiasm for native food flavours to gardeners and professional growers, foragers and foodies, cooks and chefs.

Now, through trade curriculae, he has written, Australian Native Cuisine is being taught to apprentice chefs who will be serving their creations to international and local audiences come the Sydney 2000 Olympics and beyond.

Today, Vic Cherikoff runs his business in partnership with Bradley Field and a team of highly motivated bushfood devotees who keep BTS Aust. leading the way for the future of Australian cuisine, both domestically and internationally.

SUMMARY The report deals largely with plant based foods but also provides an overview of animal based bushfoods. Fourteen plant species are considered as they have definable commercial values. 

Production issues are examined: 

• lack of genetically improved cultivars of most species 

• lack of cost effective and environmentally sound management practices to support production 

• apparent over-planting of some species which may result in lowered prices unless demand is increased 

• farmgate prices which are unlikely to be acceptable to larger scale market outlets 

• lack of product quality and safety information.


Eat Your Garden

Bushfoods and Permaculture join forces to give us the best of both worlds...

Jennyby Jenny Allen

People often equate harvesting bushfoods with wrestling crocodiles Mick Dundee style. For your own bushfood ad­venture, with a touch less peril, you can grow an exciting array of ed­ible native plants throughout your home garden. Here are some plants that are easy to grow with great rewards

WARRIGUL GREENS

Tetragonia tetragonoides Growing wild in every state of Aus­tralia, warrigul greens is a great substitute for the European spin­ach and, in many cases, a lot easier to grow. Although it is believed relatively little was eaten by Abo­rigines, it was very popular with Captain Cook and his crew when they arrived in Botany Bay.

They ate it to ease their scurvy and were so pleased with it they took it back to the Kew Gardens to grow. Now it is the major native Austral­ian vegetable to be eaten interna­tionally.

It's a useful plant as it grows in both sun and semi-shade, although more prolifically in the former. I let it sprawl underneath my fruit trees, acting as a great edible groundcover. Conveniently, it reseeds itself so my supply is continual. It is perennial although slow.warrigal

Warrigul greens can be grown from seeds or cuttings - which you may just find at your local beach. As it grows naturally on sheltered beaches and plains it is adaptable to the dry, although it prefers ad­equate moisture. It needs a lot of nitrogen to support its leafy habit, especially if you harvest it often. It handles frost to minus 3 and can be harvested all year round except late winter when it has slow growth and the seeds are setting. It yields about 1-3kg per square metre per season.

Eat the new stem, the leaves and the last 5 cm of growing tip. It does contain calcium oxalates, yet these can be removed by blanching - don't reuse this water. Apparently, better flavoured low oxalate forms are being developed in Europe - who knows, before long it may be

 

SMALL-LEAVED LILLY PILLY

RiberrySyzygium leuhmanni

The bliss bomb!!! This lilly pilly has a spicy fruit, tasting of an interesting mix of cardamon, cinnamon and cloves! It is a stunning tree with pink young foliage, making it a very popular street and screen tree. Growing 5-10m, it attracts birds, is a good windbreak, is fire retardant, can be planted along creeks and is good for erosion control.

It prefers well-drained soil and is not frost tolerant. It can grow in both full sun and part shade al­though fruits best in the former. Select trees with fruit that is seed­less or has small seeds. It fruits in 3-4 years and there has been a re­port of 75 kg of fruit harvested from one tree!

LEMON SCENTED MYRTLE 

Backhousia citriodora

If you want a refreshing cup of tea at your finger tips you can't beat this beautiful myrtle. In fact, it is such a good cleanser a friend of mine who smokes believes if he drinks a cup of lemon myrtle tea he can have twice as many ciga­rettes!

It is a fast growing tree, reaching 3-8m and enjoys full sun. It pre­fers a protected site and in many cases can cope with poorly drained soil, although it relishes a well drained site with plenty of water. It can tolerate light frosts, although is quite tender when young. It at­tracts birds and butterflies and also grows well as a pot specimen.

It is better to harvest the older leaves as they have a better texture and retain their oil better. As it has a deeper flavour than lemon grass, with nine times its citral content, it is becoming popular in the Asian market.

FINGER LIME

FingerlimeCitrus australasica

The long, tangy fruit, growing up to 8cm long, has a lot of gourmet potential. When sliced into rings it resembles miniature cartwheels.

The finger lime bush grows 3-6m high in sun and part shade. It is very prickly, so if you plant many together they can act as a living fence, keeping out unwanted in­truders. It is fire retardant, frost hardy and can be planted on creeksides. It is slow growing and tolerates poor soils provided they drain freely. It grows faster when budded onto citrus (although it makes you wonder what the mean­ing of bushfoods is).

PIGFACE

CarpoCarprobrutus glaucescens

Quite an insulting name for an or­namental creeper with stunning flowers and interesting fruit. Plant it in full sun. As it likes a lot of minerals, especially Potassium, Magnesium and Calcium, feed it woodash, dolomite and rockdust.

The carprobrotus species grows commonly on beaches, with glaucescens found in NSW and Queensland. It grows easily from a cutting. The fruit is delicious, tasting like a slightly salty straw­berry. If it is grown away from the beach it is not so salty.

Don't eat the skin, just squeeze the fruit and suck the end. The crushed leaves help ease the pain of sun­burn, burns and bites.

MIDYIM BERRY

MidyimAustromyrtus dulcis

This is one of my favourite bushfoods as not only is it so tasty, it is also a versatile little plant fill­ing in many nooks throughout my garden. It grows I in high and I in wide and handles both sun and part shade. It enjoys moist but well-drained soil. It is frost tolerant, fire retardant, decorative and attracts birds. A great all-rounder. It fruits mainly in autumn. The one cm wide fruits are white with delight­ful pink spots. They have a slight ginger flavour. Fantastic snacks for the kids.
