Abstract:
L'invention concerne un procédé pour éliminer d'un extrait naturel au moins un composé organique gênant. Ce procédé consiste à soumettre l'extrait (en 1) à une irradiation au moyen d'un faisceau laser (4) dont la longueur d'onde correspond à une bande d'absorption du(des) composé(s) gênant(s) pour transformer ceux-ci en composê(s) non gênant(s) et/ou facilement séparable(s) de l'extrait. Par ce procédé, on peut éliminer les thujones d'un extrait de sauge, traiter un mélange de phycobiliprotéines pour détruire la phycoérythrine ou la phycocyanine, ou traiter un extrait de bergamote pour éliminer le bergaptène.
Abstract:
A pie, such as a meat or fruit pie, having a bottom crust which is suitable for baking and browning in a microwave oven is provided. A preferred bottom crust contains a reducing sugar such as dextrose, an amino acid source such as whey solids, a dough conditioner to prevent dough shrinkage and a leavening agent to enhance browning and to provide a puffy crust. The pie filling contains less than 90 weight % water. The pie is supported in a tray composed of a microwave-interactive material which heats upon exposure to microwaves. The bottom crust of the pie browns as a result of several browning phenomena including low temperature Maillard browning reactions and high temperature caramelization reactions.
Abstract:

The method comprises the steps of: - stirring vitamin C and resveratrol in water to a first mixture, - stirring lecithin in water to a second mixture, - stirring the first and the second mixture to a third mixture, and - processing the third mixture by means of ultrasound until a smooth composition is obtained.
Abstract:
The present invention relates to a food preparation comprising at least one vegetable from Alliacee divided into separate pieces and subjected preferably to partial dehydratation, an acidity regulator and optionally at least one edible oil in mixture to each other. The Alliaceae vegetable is preferably onion, garlic or combinations thereof. Such food preparation can be obtained according to the present invention by a method comprising the steps of 1) subdivision of at least one vegetable from Alliaceae into separate pieces, 2) addition of an acidity regulator to said at least one vegetable from Alliaceae in separate pieces to form a mixture, 3) optional addition of an edible oil to said mixture, 4) irradiation of the mixture with a light beam containing ultraviolet light, 5) packaging of the mixture irradiated with a light beam containing ultraviolet light in at least one container for foods and 6) sanitization of the mixture packed in said at least one container for foods by means of microwaves. Said mixture can be irradiated with ultraviolet rays, preferably UV-C rays (100-280 nm) or can be irradiated with high-intensity pulses of a beam of polychromatic light containing ultraviolet rays. The packaged food preparation of the invention can be used effectively as a vegetable food base both for the direct preparation of food or food products ready to eat, by mixing it to further ingredients of the recipe of interest, and for the preparation of further intermediate food preparations, such as fried based on Alliaceae which in turn will constitute starting food base for obtaining food or food products, all according to the most varied recipes in particular but not exclusively of the Mediterranean cuisine.
