Abstract

PURPOSE:To enhance the decoloration, deacidification and deodorizing effects of oils and fats, by preparing an adsorbing aid from an organic acid salt compound being a reaction compound of one or more of org. acid and one or more of a calcium ion and a magnesium ion. CONSTITUTION:An adsorbing aid is obtained by reacting one or more kinds of org. acids such as carboxylic acid and ascorbic acid etc. with one of or both of a calcium ion and a magnesium ion. Or, the adsorbing aid is obtained by reacting one or more kinds of org. acids such as carboxylic acid and ascorbic acid etc. with one of or both of a sodium ion and a potassium ion. If this adsorbing aid is used in combination with known adsorbents, the decoloration, deacidification, peroxide removal and deodorizing effects of oils and fats as a low temp. zone and a high temp. zone (50-200 deg.C) can be simultaneously developed.

Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention is capable of decolorizing, deacidifying, deperoxidizing, deodorizing, etc. It relates to adsorption aids and adsorbents containing adsorption aids that are intended to exhibit adsorption functions even in high temperature ranges without deteriorating their adsorption capabilities. <Prior art> As a conventional method for recycling waste oils and fats, there is a method in which waste oil and an organic solvent are mixed and cooled to -30°C to -40°C to separate unpolymerized parts and polymerized parts (Japanese Patent Publication No. 58-25400). ) or a method of slowing down the oxidation rate of oil by immersing maifan stone in fats and oils (Japanese Patent Publication No. 57-26100), or a method of slowing the oxidation rate of oil by coating the metal surface of a heating container and immersing maifan stone ( (Japanese Patent Publication No. 58-162248) Alternatively, as a decolorization method, there is a method using a precision filtration machine, a method that slows down the deterioration of oil by using oil and water together in a fryer, or a method that uses electricity to oxidize by charging with heavy wave electricity. Calcium and magnesium oxides, hydroxides, carbonates, and calcium silicates as slowing methods or as deoxidizers;
There have been reports of magnesium silicate, aluminum hydroxide gel, etc., but these deoxidizing temperatures are carried out at a low temperature of 80°C, and the drawback is that at higher temperatures the color increases and the deoxidizing power decreases. There are other conventional methods for refining oils and fats, all of which involve low-temperature processing. <Problems to be Solved by the Invention> In the conventional methods for refining, preventing deterioration, or regenerating fats and oils, the steps of decolorization, deoxidation, deperoxidation, and deodorization are performed individually, making the process complicated. However, decolorizing adsorbents have drawbacks such as deterioration of fats and oils or reduction of decolorizing power when treated at high temperatures, so conventional methods such as decolorization, deoxidation, removal of peroxides, deodorization, etc. are used. Doing so has the disadvantage of causing deterioration of the fats and oils. <Means for Solving the Problems> In order to solve the above-mentioned conventional problems, the present invention is based on "Compositions with Adsorption Function" Application No. 60-200285 and September 30, 1985 "Adsorption Aids and The problem was solved by the patent application for "Adsorbents Containing Adsorption Aids, etc.", and the present invention has solved the problem by applying the adsorption aids such as organic acid salt compounds, etc., or the adsorption of organic acid salt compounds, etc. to adsorbents, etc. that have been used conventionally.

This problem has been solved as deodorization can be done at the same time even in high temperature ranges. <Function> The above-mentioned adsorbent can be used in combination with conventionally used adsorbents, etc. in the low temperature range and high temperature range (50°C to 200°C).
), it is not only possible to simultaneously perform decolorization, deoxidation, deperoxidation, deodorization, etc. of fats and oils at the same time. It decolorizes, deoxidizes, removes peroxides, deodorizes, etc. by contacting with an adsorbent containing adsorbent, thereby keeping the amount of degrading substances in fats and oils in a state with few deteriorating substances, and preventing the progress of deterioration of fats and oils due to an autocatalytic reaction mechanism. It is also possible to regenerate oils and fats to a state close to that of new oil. It is also possible to use it in combination with previously reported deoxidizing agents. <Example> Compounds used as organic acids such as carboxylic acids, calcium and magnesium ions, sodium and potassium ions, silicates, and aluminum salt compounds according to the present invention will be explained. 1. carboxylic acid.
