Deep-Frying has been a very popular method of food preparation since living memory. During the heating period many deterioration products are formed which can lead not only to bad flavouring of the fried produce but also cause unpleasant smoking or string foaming. Often the consumer suffers from a gastrointestinal distress after consuming fried foods in restaurants. The formed compounds do not have well proven detrimental effects to health. This may be the reason for there not being specific laws concerning the evaluation of frying fats from the health authorities' point of view. Newer scientific findings about acrylamide, cyclic compounds, heterocyclic aromatic amines in fried food or mutagenic polycylic aromatic hydrocarbons in the fume of cooking oils may change this careless attitude to fear. Furthermore, new quick tests and analytical procedures will be demonstrated. The application of stabilizing agents and other additives for the prolongation of the lifetime of fats and oils in the fryer will also be discussed. The symposium should be an opportunity for all who are interested in the field of deep frying processing to update their knowledge and to discuss open questions. The past has demonstrated how important the DGF Symposia on Deep Fat Frying are. I look forward to seeing you in Hagen.
