Abstract: This invention relates to a method for preparing chlorogenic acid from potatoes and the use of chlorogenic acid to prevent or inhibit browning reactions in potatoes after cooking, in particular dehydrated potato flakes.

Abstract: The present invention relates to a method for preventing acrylamide formation in heat-treated food stuffs, in particular in the case of a food processing that involves a frying step and/or a cooking step, which method comprises blocking conversion of glycerol into acrylamide.

Abstract: This invention relates to a method for preparing chlorogenic acid from potatoes and the use of chlorogenic acid to prevent or inhibit browning reactions in potatoes after cooking, in particular dehydrated potato flakes.

Abstract: The invention relates to starch-based dehydrated flakes comprising 0,05% glycolipid(s) which, when reconstituted, are similar in quality, taste and texture to freshly prepared mashed material.

Abstract: A method for separating a composition containing glycolipids, lysopholipids, sphingolipids and ceramides of plant origin is described. A liquid alcohol is heated to a temperature of between 50.degree. and 80.degree. C., a plant composition or plant extract is introduced into the alcohol to form a mixture, the mixture is hot-filtered so as to separate the filtrate from a dilapidated filter cake, and the alcohol is evaporated from the filtrate such that a lipid residue which contains glycolipids, lysophospholipids, sphingolipids, and ceramides is obtained. The lipid residue can be used in cosmetology or dermatology.

Abstract: A method for the detection of delaminated areas in coated materials or layered composites, which allows free-air operation and can be used to scan portions of bulky materials on the spot. This method which makes it possible to detect very small delaminated areas in a very short time (less than 1 millisecond), with a very high sensitivity and without creation of excessive thermal stress in the inspected material, basically comprises the steps of: focusing pulsed, thermal radiations onto the structure to be inspected to produce a vertical displacement of its coating by thermal expansion if a delaminated area is present at the coating-to-substrate interface, and detecting and measuring this vertical displacement if any, by interferometry, preferably laser-beam interferometry. An apparatus for carrying out this method is also disclosed.
