Worldwide almost 2 billion people suffer from 'Hidden hunger', a shortage of one or more micro elements. Researchers of Wageningen UR Greenhouse Horticulture Wim Voogt and Caroline Labrie presented research on bio fortification and flavour of crops on substrate on the Knowledge Day Substrates 2014.
Wim Voogt uses substrate growing as a means to supply crops with extra elements, which are lacking in the average consumer diet (bio-fortification). Lettuce was successfully grown with a higher level of iodine. Other such elements are iron, selenium and zinc. Worldwide almost 2 billion people suffer from 'Hidden hunger': a shortage of one or more micro elements. Consequences are bodily and mental setbacks and consequently unfit and unproductive persons.
Health promoting substances
Caroline Labrie showed research on consumer acceptation of crops with extra health promoting substances such as vitamins and minerals. She pointed out it is much more effective to seduce consumers to buy attractive good tasting products than to convince them with health or environmental arguments. Taste thus becomes a carrier for the additional advantages. Besides this it is important nice tasting vegetables taste nice all the time and, as A brands, are recognizable for consumers.
The Knowledge Day Substrates was organized by Wageningen UR Greenhouse Horticulture on April 3 in Bleiswijk and hosted over 100 substrate industry specialists.
