It is an object of the present invention to provide a novel technique related to electric field treatment of edible oil.

The present invention is an electric field treatment device for edible oil, the device including: an energization unit that is capable of being installed in at least one of side surface regions of an oil reservoir having a heating unit, wherein the heating unit is capable of heating a side surface and/or a bottom surface of the oil reservoir, and is capable of forming heat convection of the edible oil in both directions of the side surface region including the energization unit in the oil reservoir and a central region in the oil reservoir, and the energization unit is capable of applying an alternating electric field to the edible oil provided in the oil reservoir, includes at least two electrodes having a gap or a hole which is a path of heat convection of the edible oil and locally increases an electric field intensity applied to the edible oil, and applies the alternating electric field.

Suggested is a composition with stabilized taste and/or odor, comprising (a) [6]-paradol and (b) at least one mono- or polyunsaturated C.sub.8-C.sub.22 fatty acid or its monohydric or polyhydric C.sub.1-C.sub.18 aliphatic alcohols ester.

Taste-enhanced liquid, semi-solid and/or solid oil-based suspensions are provided, which consist of a carrier oil and edible solid particles (e.g., crystalline salt and/or sugar, and optionally spices) having median diameter of less than 15 m. The particles are reduced in size in the suspension, allowing enhancement of their organoleptic effects while reducing their amount to meet nutritional demands. The solid or semi-solid oil-derivatives comprise heterogeneous triglycerides of saturated fatty acids, including at least one saturated fatty acid having 12 carbons or more-selected to provide a required temperature-viscosity profile and/or a required melting temperature profile of the oil-derivative that corresponds to the food product. Also, non-oxidizing frying oil is provided, based on saturated fatty acids. The frying oil comprises triglycerides that include mostly or wholly saturated fatty acids, as well as small amounts of antioxidants that prevent residual oxidation of the oil during prolonged frying.

Provided is a fat or oil composition having high oxidative stability even though containing large amounts of eicosapentaenoic acid and docosahexaenoic acid, and having suppressed degradation odor and unpleasant odor derived from a rosemary extract at the time of cooking. The fat or oil composition comprises the following components (A), (B), and (C):(A) a fat or oil in which a total content of eicosapentaenoic acid and docosahexaenoic acid in constituent fatty acids of the fat or oil is from 0.1 to 20 mass % with respect to total constituent fatty acids of the fat or oil; (B) a rosemary extract; and (C) a dill extract, in which a mass ratio of a content of the component (B) to a content of the component (C), [(B)/(C)], is from 2 to 200.

Provided is a fat and/or oil composition for heat cooking, comprising a fat and/or oil, and an alkali metal soap of a saturated fatty acid having from 4 to 16 carbon numbers, wherein an alkali metal content in the fat and/or oil composition for heat cooking is from 0.1 to 5.0 mass ppm, and a method of preparing the same. Also provided is a method of preventing deterioration of a fat and/or oil for heat cooking caused by heating, comprising the step of adding an alkali metal soap of a saturated fatty acid having from 4 to 16 carbon numbers to the fat and/or oil for heat cooking to produce an alkali metal content in the fat and/or oil composition for heat cooking of from 0.1 to 5.0 mass ppm.

Suggested is a composition with stabilized taste and/or odor, comprising (a) [6]-paradol and (b) at least one mono- or polyunsaturated C.sub.8-C.sub.22 fatty acid or its monohydric or polyhydric C.sub.1-C.sub.18 aliphatic alcohols ester.

Disclosed is a radiant catalytic ionization detoxification system including a gas-liquid mixer configured to gas-liquid mix air carrying radiant catalytic ionized Reactive Oxygen Species with liquid material to be detoxified, and a reaction tube configured to circulate the mixed gas-liquid mixture. The detoxification system of the present disclosure is applicable to water sterilization or aflatoxin removal in edible oils. The radiant catalytic ionization chamber in the system can provide the system with air containing Reactive Oxygen Species, wherein mesh panels coated with photocatalytic materials are configured inside the chamber body, which configuration not only increases the photocatalytic material content per unit volume, but also expands the light-exposed surface area due to uniform distribution of the photocatalytic materials on the mesh panels. The system uses a U-shaped tube as the reaction tube, and the length of the reaction tube can be freely designed according to the practical detoxification requirements.
