RE SEARCH Frying is healthy! THE ONLY C THE NETHERLANDS KNOWS IS THE C OF CHEAP. Who doesn’t know about Health, Convenience and Enjoyment? According to the marketing gurus, these are the pillars on which modern Dutch consumers put their hopes as far as the purchase of food is concerned. Lister also points to the increasing importance paid by consumers in her own country to health. This may be partly true, the health characteristics of the potato are a long way from receiving the appreciation or financial valuation they deserve. The only C a country like the Netherlands knows is that of Cheap, that’s what we have learned from practice. It is completely different in Britain Someone who knows all about that is Jos Bus from TPC in the Dutch town of Emmeloord. Two years ago, the potato trading company presented the Zuyder Zee truffle at the international variety show. A potato with a splendid purple skin and purpleveined flesh as well, somewhat comparable with the New Zealand Purple Heart. Much more attractively shaped than the old wellknown Vitelotte Noir, with a higher yield per hectare. You would think that so much health would be wonderful for the deluxe shelves in the supermarkets. ‘Yes’, is Bus’ answer, ‘it is in the UK, but not in the Netherlands. In big supermarkets, health is still not an issue. Everything is about price here. Cheap is better, is what they all are saying. It is completely different in Britain. Also as a result of school campaigns, the focus is much more on healthy food. That’s why we would very much like to sell the truffle potato in this country. In doing so, we will definitely focus on the many healthy properties of the potato.’ ‘Everything is about price here. Cheap is better, is what they all are saying. It is quite different in the UK’, according to TPC’s Jos Bus. tively more skin than big ones. By the same token, the concentration or activity of antioxidants is closely related to the skin colour of the potatoes. White-fleshed varieties with a white skin contain the lowest concentration and purple/redfleshed varieties with purple/red skins the highest. Generally speaking: the darker the skin and colour of the flesh, the more antioxidants the potato contains.

The white-fleshed and white-skinned Ilam Hardy contains a total of 76 milligrams of antioxidants per 100 grams of dry matter. In the redskinned and white-fleshed Red Rascal, the total is 95 milligrams per 100 grams of dry matter. If the flesh had been yellow, the figure would without any doubt have been higher. The Purple Heart truffle potato, dark-purple skin with purpleveined flesh, has an antioxidant concentration of 366 milligrams per 100 grams of dry matter and the wild black truffle potato Urenika contains as much as 775 milligrams of antioxidants per 100 grams of dry matter. The Urenika is also known in New Zealand as the Maori potato, which was already being grown by the original inhabitants of the islands hundreds of years ago. This Urenika very much resembles the French Vitelotte Noir, in the Netherlands known as the black truffle potato. 20 Potato World 2011 • number 3 Pagina 19
