![]() Companies do not have to wait until the new technique has been fully developed: They can still use the current model predictions for flavour levels to guarantee and develop the flavour of fresh tomatoes. This can be applied in every greenhouse, every warehouse and every shop environment. This method is to use a handheld and non-destructive sensor, predicting the outcome of a hedonic panel from direct measurements. Based on our existing knowledge and experience we will develop a new flavour model for tomato with non-destructive input parameters. In February 2019 also a new project will start. In the spring of 2019, the calibration experiment will be repeated. We concluded that adaptation of the model is not necessary. In an experiment with 18 varieties of different flavour levels, the model predicted 92% of the flavour differences. The results showed that the present model is still a good and reliable predictor of flavour levels. A large array of different flavour levels was presented to the panel. ![]() Users of the model sent in tomato samples of different flavour levels. In September 2018 a new calibration experiment was held. Regular calibration tests are necessary to ensure that current developments in breeding and the development of flavour perception of consumers are properly reflected in the model prediction. The algorithm of the model that calculates the flavour from the underlying input parameters has evolved over the years through calibration experiments. It facilitates B2B communication on flavour and thus contributes to transparency and trust in the chain. The flavour model of Wageningen University & Research is a reliable tool to determine flavour levels of new tomato varieties. Together with Kenniscentrum Papier & Karton and Kenniscentrum Plantstoffen, Wageningen UR is also investigating whether tomato stems can be used in cardboard production.Regularly testing the tomato flavour model ![]() Wageningen UR developed this tomato packaging together with the Dutch Product Board for Horticulture, tomato growers and packaging producers. Several of Wageningen UR’s biobased economy related research projects focus on developing materials from agro-residuals. Wageningen UR works together with different partners to develop sustainable technologies for converting biomass into products. A biobased economy is an economy in which companies convert biomass into products, chemicals and energy. ‘Biobased economy’ is an important research and development theme at Wageningen UR. “This way, we use of plant based materials efficiently, a good example of biobased economy.” (Christiaan Bolck, Programme Manager biobased materials) This is how Wageningen UR contributes to improving the quality of life. By producing their own packaging the tomato growers reduce their carbon footprint. ![]() Tomato growers produce more than enough leaves and stems to package tomatoes in their own leaves. This packaging even smells like tomatoes. One of the products they developed was tomato packaging made from tomato leaves and stems. While searching for ways to reuse this natural material, researchers at Wageningen UR discovered that the fiber pulp from tomato plants can be used to produce packaging material. Up until now these leaves and stems went straight onto the compost pile. Printed by: Digigrafi, Wageningen, Netherlands ISBN Agromisa: 90-8573-039-2 ISBN CTA: 92-9081-299-0. Tomato growers are always left with a lot of leaves and stems. ![]()
