DEPARTMENT OFPRIMARY INDUSTRIESVegetable - -Matters--of-- FactsBased on research funded by the vegetable growers levy,Horticulture Australia and the Department of Primary Industries-VictoriaNumber 17October2004Vital Vegetables - 2004The Vital Vegetables projectVital vegetables is a large, collaborative project that aims to: Develop high value products that will help the vegetable industry be more competitiveon local and export markets Develop new vegetable and food products that have specific health benefits Supply consumer demand for healthy, fresh productsTrial plot of selected broccoli hybrids atGatton, Qld.“Vital Vegetables” is a collaborative projectbetween New Zealand and Australia. Thehealth benefits of vegetables will beresearched and promoted though a 5 yearproject. The project aims to develop newproducts and provide information onmaximising the health benefits of vegetables.DPI Knoxfield Scientists, Sonja Winkler &Peter Franz applying postharvest treatmentsto broccoliOpportunities for Vital VegetablesMarket evaluation has shown thatconsumers would: Buy new vegetables that have provenhealth benefits. Prefer to obtain the health benefits byeating fresh fruit and vegetables. Are willing to pay a premium of up to30% above the price of traditionalproducts.Health Benefits High vegetable and fruit consumptionis associated with lower levels ofsome cancers and heart disease. In particular, Crucifer vegetables (egbroccoli, pak choi and water cress)are associated with lower levels ofsome cancers.The project is initially focussed onvegetables with anti-cancer and antioxidantcompounds, which are prevalentin Brassica vegetables, some leafy saladvarieties and various sprouts.New Products New varieties, growing andpostharvest protocols New processed and value-addedproducts will also be developed. Crop & Food Research in NZ areresearching ways of using vegetablefibre in new food products.


Main areas of work Market evaluation Selection and breeding of vegetables with highhealth benefits. Genetic engineering is not used Investigate how vegetables produce healthbenefits in humans Production methods to achieve high levels ofbeneficial compounds Postharvest handling to retain quality and healthbenefits after harvest. The Crop & Food Research (NZ) scientists arestudying the underlying mechanisms that controlquality of vegetables. Processing and food ingredients from vegetables.Progress so far… Broccoli and other brassica vegetables with highlevels of anti-cancer and anti-oxidant compoundshave been selected. These are currently being tested for postharvestshelf life and to assess how they grow andproduce these valuable compounds in differentclimates. We are also exploring a broad range of othervegetables to find ones that have specific healthbenefits, good quality and shelf life for whole andminimally processed vegetables and salads. We have tested ways of improving the levels ofhealthy compounds in the vegetables by alteringgrowing conditions, including fertilisers, water andsalt stress.Are you on our mailing list?If you would like to receive your own copy of VegetableMatters-of -Facts or have changed your address, pleasemail or fax this coupon to:Craig Murdoch, Private Bag 15, Ferntree GullyDelivery Centre 3156; Fax (03) 9800 3521.Name: ________________________________________Address: ______________________________________Postcode___________ Email _____________________Organisation/Business ___________________________Crops of interest_________________________________For more information please contact yourlocal VegCheque officer.Neville Fernando Gippsland 5152 0600Sally-Ann Henderson Northern Vic 5051 4500Bruce Fry South West Vic 5233 5510Craig Murdoch Melbourne 9210 9354Some ResultsThe clearest results to date are that high levels ofnitrogen fertiliser decrease the amount of healthycompounds. Postharvest treatments also have an effect onthe level of healthy compounds, but generally thehandling conditions that keep quality, alsomaximise the healthy compounds.Cooking causes about a 50% loss of the healthycompounds, depending on the method used.Some other processing methods also destroysome of the healthy compounds.We have tested the ability of the selectedbroccoli to increase the body’s natural defencesagainst cancer and our top variety is 2 to 3½times more effective than current commercialvarieties.Vital Vegetables, is a Trans Tasman research projectjointly funded and supported by Horticulture AustraliaLtd, New Zealand Institute for Crop and FoodResearch Ltd, the New Zealand Foundation forResearch Science and Technology, the AustralianVegetable and Potato Growers Federation Inc, NewZealand Vegetable and Potato Growers FederationInc and the Victorian Department of PrimaryIndustries.For more information: “Horticultural products as functional foods – aconsumer perspective” (market research).
