Decolorizing agent capable of decreasing aflatoxin content in peanut oil

[0023] Example 1

[0024] A decolorizing agent capable of reducing the content of aflatoxin in peanut oil, which is prepared according to the following process:

[0025] Step 1) Add twice the weight of a 10% hydrochloric acid solution to the diatomaceous earth, ultrasonically shake for 30 minutes, add 1% by weight of diatomaceous earth sodium dodecyl sulfonate, and continue ultrasonic vibration for 30 minutes. Then centrifuge to collect the precipitate; the ultrasonic power is 2000w;

[0026] Step 2) Put the calcite, zeolite and sepiolite into the pulverizer according to the mass ratio of 2:2:1, and then grind them into 100 mesh powder;

[0027] Step 3) Put the precipitate obtained in step 1) and the powder obtained in step 2) into a blender at a mass ratio of 1:2, stir at 500 revolutions / min for 10 minutes to obtain a mixture, and then mix it with polystyrene microspheres in a ratio of 1:1 The mass ratio is added to the granulator, and then a polyvinyl alcohol aqueous solution with a

[0030] A decolorizing agent capable of reducing the content of aflatoxin in peanut oil, which is prepared according to the following process:

[0031] Step 1) Add twice the weight of a 10% hydrochloric acid solution to the diatomaceous earth, ultrasonically shake for 30 minutes, add 2% by weight of diatomaceous earth sodium dodecyl sulfonate, and continue to ultrasonically shake for 30 minutes. Then centrifuge to collect the precipitate; the ultrasonic power is 2000w;

[0032] Step 2) Put the calcite, zeolite and sepiolite into the pulverizer according to the mass ratio of 2:2:1, and then grind them into 200 mesh powder;

[0033] Step 3) Put the precipitate obtained in step 1) and the powder obtained in step 2) into a blender at a mass ratio of 2:3, stir at 500 revolutions / min for 10 minutes to obtain a mixture, and then mix it with polystyrene microspheres in a ratio of 1:1 The mass ratio is added to the granulator, and then an aqueous solution of polyvinyl alcohol

[0035] Example 3

[0036] Put the used decolorizer into water at 50-60℃ and soak for 30min, take it out, calcinate it at 300-350℃ for 3-5min, remove the adsorbate, cool it naturally, and then use it again.
