摘要:
Oil of improved quality is produced by treating the oil with an active substance capable of reducing the anisidine value of the oil. Food products comprising the oil of improved quality are also disclosed.
摘要:
A food composition in which omega-3 fatty acids are stabilized against oxidation is disclosed. The food composition contains about 4 to about 100 weight percent of the composition in which triglycerides containing omega-3 fatty acids (and other fatty acids) are stabilized against oxidation in the absence of encapsulation. The fatty acid portion of the oil in the completed food composition includes less than about 10 percent by weight linoleic acid, at least 75 percent by weight of monounsaturated plus saturated fatty acids, and at least 3 percent by weight omega-3 fatty acids. The food composition can also contain comminuted peanuts, e.g., peanut butter, in which case the composition is also stabilized against photo-oxidation and the fatty acid portion of the oil portion of the food can contain less than about 15 percent by weight linoleic acid and at least 1 percent by weight omega-3 fatty acids. Methods of protecting a food composition from oxidation and photodegradation are also disclosed.
摘要:
A method for improving the quality and safety of a cooking oil while extending the working life of the cooking oil includes the steps of applying a nonreactive gas or a non-reactive gas mixture to a cooking oil, with a food residue therein, during the working lifetime of the cooking oil. Thereby, reactions, which degrade the cooking oil, may be inhibited. Furthermore, the formation of acrylamide within or on foods cooking in the oil may be inhibited. An optional step of pre-treating and/or packaging a food product before it is cooked in the cooking oil, whereby oxygen is removed and/or excluded from the food product and/or the ambient of the food product, may enhance the results that can be obtained by the invention. Preferably, the optional pre-treatment and/orpackaging step is applied to the food product before it is cooked in the cooking oil. Consequently, the quality of a cooking oil can be maintained and its working life can also be extended. Moreover, the safety risk due to acrylamide formation within or on fried foods can be minimized.
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:
Disclosed herein is a method for the preparation of a hydrogenated vegetable oil (containing or not containing CLA) having a reduced hydrogenation odor emission, and a use of the hydrogenated vegetable oil as a food ingredient. The method comprises the steps of degumming, neutralizing, bleaching, hydrogenating, and deodorizing a crude vegetable oil. The vegetable oil is added with an antioxidant, after the bleaching step, but before the hydrogenation step. By virtue of the addition of the antioxidant, a production of volatile compounds in the vegetable oil is inhibited during the hydrogenation step.
摘要:
A method is described for preparing mixtures of salts and/or other substances in general, including calcium and magnesium salts with carbon dioxide in pressurized containers, for the purpose of producing systems for the delivery of said mixtures in soluble form ant at a predetermined and constant saline concentration, for a wide variety of applications. The mixtures containing the substances are prepared in a stirred reactor under a pressure of carbon dioxide, and from there are brought into use after they have been transferred into containers that are suitable for maintaining the internal pressure generated by the carbon dioxide in the form of vapour, in the form of a liquid/vapour mixture or under supercritical conditions.
摘要:
The oil content of bran can be stabilized by the addition of a stabilizing agent to grain prior to, during or after milling of the grain, particularly rice. The treatment improves the yield of edible oil attainable when the oil is extracted from the milled bran.
