Problems solved by technology

At this time, the production company has already paid a huge cost for refining and processing corn oil. Even though the other indicators of the finished corn oil meet the requirements of the national standard, it is still unqualified only because of its too dark color. products, causing huge losses to the production enterprises both economically and in terms of reputation
How to solve the problem that the finished edible oil obtained after the refining process of oil and crude oil will not return to color? There is no definite answer to this question

[0230] According to the raw material selection and proportioning in Table 2, the corresponding crude corn oil composition is prepared according to different ratios, and according to the standard of GB / T 24304-2009 "Determination of Anisidine Value of Animal and Vegetable Oils and Fats", measure the content of each mixed sample respectively. Anisidine value (p-AV 总 ) (results in Table 3). Then, each mixed crude corn oil sample was subjected to a laboratory simulated refining process, during which the anisidine values ​​of each corresponding intermediate product obtained after the chemical refining treatment in the refining process—chemically refined corn oil were compared with the same The standard method is measured, thereby calculate the ratio (macromolecule %) of the aldehyde, ketone carbonyl compound that exists with macromolecular glyceride bound state in total aldehyde, ketone carbonyl compound after mixing (results are shown in Table 3). Continue to simulate physical refi...

[0243] According to Table 4, 200 g of the corresponding crude corn oil compositions in Table 2 were taken respectively, and the anisidine value was reduced by laboratory adsorption, and the treatment of macromolecular glyceride-bound aldehydes and ketone carbonyl compounds was removed. The specific method is to use a flask to weigh about 200g of mixed crude corn oil, put it into a stirrer, add silica gel bonded aminopropyl adsorbent according to the amount of adsorbent in Table 4, continuously feed nitrogen to drive away the air, and then seal it. Place it on a magnetic spiral constant temperature heating plate, stir and heat to about 30°C-40°C under the protection of nitrogen gas, react for 3 to 4 hours, stop the reaction, and remove the adsorbent in the crude corn oil by suction filtration to obtain Processed crude corn oil.

[0244] The crude corn oil sample obtained by each treatment was subjected to laboratory simulation refining process, during which the anisidine value ...

Abstract

The invention provides an oil composition, in which the content of total aldehydes and ketone carbonyl compounds is represented by the anisidine value of the oil composition, and the anisidine value is not more than 9; meanwhile, the content of total aldehydes Based on the amount of ketone carbonyl compounds, the proportion of aldehyde and ketone carbonyl compounds in the macromolecular glyceride bound state in the total aldehyde and ketone carbonyl compounds is not more than 80%. The color reversion time of the oil composition after refining can be significantly prolonged, or the color reversion during storage can be suppressed. In addition, the present invention also provides a method by adjusting the anisidine value of the oil composition to not more than 9; and / or adjusting the aldehyde and ketone carbonyl compounds existing in the state of macromolecular glyceride in the oil composition The proportion of the total aldehyde and ketone carbonyl compounds is not more than 80%, so as to achieve the purpose of prolonging the color return time after refining or inhibiting the color return during storage.

Description

technical field [0001] The invention relates to an oil composition, in particular to an oil composition which is not easy to return to color after refining. Background technique [0002] After degumming, deacidification, decolorization, deodorization, dewaxing and other refining processes, the refined edible oil obtained from the crude oil is clear and bright, and the color is light yellow. In general, the light color of the refined edible oil is relatively Stable and can last for a relatively long period of time. However, in a few cases, the color of some refined edible oils will be significantly deepened (mainly because the red value (R value) increases significantly) or even turn red in a relatively short period of time. This phenomenon is called For the back color of grease. At present, the problem of color return of edible oil is very common, and there are many studies by various parties [1] . As early as the 1920s, some scholars paid attention to and studied the co...
