specific Embodiment approach 1

[0015] Specific implementation mode one: the steps of this implementation mode are as follows:

[0016] Step 1: Place the oil away from light, irradiate the soybean oil with VIS-450 light to destroy a certain amount of pigment; add attapulgite with an oil weight of 1.2% to the soybean oil for decolorization, select a current intensity of 7-25A, and Under a certain temperature and stirring speed, stir for a period of time to carry out the decolorization reaction, then centrifuge at 5000r / min for 10min, take the upper layer of decolorized oil, measure its color, and determine the current intensity;

[0017] Step 2: Add attapulgite with an oil weight of 1.2% to a certain amount of soybean oil, select a decolorization temperature of 60-100°C, stir at a certain stirring speed for a period of time to carry out the decolorization reaction, and then centrifuge at 5000r / min for 10min, Take the upper decolorized oil, measure its color and luster, and determine the decolorized temperatur...

Abstract

In the bleaching process of oil, organic pigments easily convert into other pigments with rising of temperature, and these newly generates pigments are difficult to remove and consume a large amount of attapulgite clay. The invention adopts a method for bleaching oil by using synergistic effect of monochromatic light and attapulgite clay, namely VIS-450 monochromatic light is used for irradiating the oil while attapulgite is employed to remove colored materials in the oil. Pigments of carotenoid and chlorophyll are affected by different factors, leading to different change rules in spatial structure. Illumination factor causes devastating effects on the stability of carotenoid and chlorophyll, thereby reducing the oil color, and carotenoid almost reaches the maximum light absorption value at VIS-450. Therefore, the VIS-450 monochromatic light is used as an auxiliary means for bleaching, and VIS-450 light causes little oxidation on the soybean oil and does not cause significant impact on the quality of soybean oil, and the bleaching rate is increased.

Description

Technical field: [0001] The invention relates to the field of edible oil processing, in particular to a method in which monochromatic light and attapulgite are used in the decolorization process in the alkali refining process of oil to carry out decolorization. Background technique: [0002] In the process of oil decolorization, organic pigments are easily converted into other pigment substances during the process of temperature rise. These newly formed pigments are difficult to remove, and a large amount of attapulgite will be consumed at the same time. The present invention adopts the synergistic effect of monochromatic light and attapulgite to decolorize the oil. The VIS-450 monochromatic light is used to irradiate the oil and at the same time, the attapulgite is used to remove the colored substances in the oil. [0003] Pigments such as carotenoids and chlorophyll are affected by different factors, resulting in different changes in their spatial structure. Among them, l...
