摘要： The useful life of cooking oil is increased by treating the cooking oil with a food compatible acid to counteract the adverse effect of food juices which are dissolved in the cooking oil. The cooking oil is generally also contacted with a suitable adsorbent, such as an activated carbon, to adsorb soluble oxidized and/or pyrolytic contaminants.

摘要： Frying processes utilizing cooking oil at elevated temperatures can cause various degradation effects in the oil including oxidation, hydrolysis and/or polymerization. In the absence of additives to protect the oil, the nutritional profile and cooking performance of degraded oil diminishes the quality of food cooked therein. The disclosed methods and compositions provide beneficial and cost effective improvements in the cooking performance of oil used at elevated temperatures, for example, in food frying equipment.
摘要翻译： 在高温下使用烹调油的煎炸过程可能在油中引起各种降解作用，包括氧化，水解和/或聚合。 在没有保护油的添加剂的情况下，降解油的营养特性和烹饪性能会降低其中烹制的食物的质量。 所公开的方法和组合物提供了在高温下使用的油的烹饪性能的有益和成本有效的改进，例如在食品油炸设备中。

摘要： A method and system for filtering cooking oil in cooking vessels is disclosed. In accordance with the method and system, there is provided a collection vessel for collecting filtered oil, a filter member for filtering contaminants and particulate matter from the cooking oil, and a centrifugal pump apparatus which includes an impeller, an impeller discharge, and a flexible conduit having an inlet end connected to the impeller discharge and an outlet end. The filter member is supported in relation to the collection vessel so as to be in position to receive oil to be filtered, and then to discharge filtered oil into the collection vessel. The centrifugal pump apparatus is adapted to be placed directly in the cooking vessel so that at least the impeller thereof is in direct contact with the oil to be filtered, and the outlet end of the flexible conduit is arranged to be in position to discharge oil pumped therethrough into the filter member. When the centrifugal pump apparatus is operated, the impeller is rotated to thereby pump oil from the cooking vessel through the flexible conduit into the filter member. Also in accordance with the present invention, filtered cooking oil can be returned to the cooking vessel by simply removing the centrifugal pump apparatus from the cooking vessel, placing it in the collection vessel so that the impeller is in direct contact with the oil therein, and then operating the centrifugal pump apparatus to pump filtered oil from the collection vessel back into the cooking vessel.
