Embodiment 17-21

[0122] Embodiment 17-21 The influence of the amount of alkali added on the reduction effect of erythralenone

[0123] Take 5 parts of the same batch of refined first-grade corn oil 200mL (the content of erythralenone is 2567ppb) in a beaker, place it on a temperature-controlled stirring table, adjust the reaction temperature to 6°C, and add alkali according to Table 4. The concentration is 20%. NaOH aqueous solution, stirred and reacted for 6 hours, filtered respectively, took a sample and measured the content of erythralenone in every part of corn oil after the treatment, and the experimental results were as follows:

[0124] Table 4 The effect of the amount of alkali added at 6°C on the reduction effect of erythralenone

[0125]

[0126] As can be seen from Table 4, under the same conditions of lye concentration and reaction time, the higher the amount of alkali added, the lower the content of erythralenone. The content basically tends to be stable, but the loss of neutral...

Embodiment 22-27

[0127] Embodiment 22-27 The influence of alkali concentration on the reduction effect of erythralenone

[0128] Take 6 parts of the same batch of refined first-grade corn oil 200mL (the content of erythralenone is 2567ppb) in a beaker, place it on a temperature-controlled stirring table, adjust the reaction temperature to 6°C, add NaOH aqueous solution according to the alkali concentration in Table 5, and add alkali Amount is 0.03% (calculated as 0.055g with NaOH) of grease weight, stirring reaction 6 hours, filter respectively, take a sample and measure the content of erythralenone in every part of corn oil after processing, experimental result is as follows:

[0129] Table 5 The effect of alkali concentration on the reduction effect of erythralenone at 6°C

[0130]

[0131] It can be seen from Table 4 that under the same conditions of alkali addition and reaction time, the content of erythralenone does not change much with the increase of lye concentration and can be kept...

Embodiment 35-37

[0142] Embodiment 35-37 The influence of other alkali on removing erythralenone

[0143] Take 200mL of 3 parts of refined first-grade corn oil from the same batch (the content of erythralenone is 2567ppb) in a beaker, place it on a temperature-controlled stirring table, adjust the reaction temperature to 6°C, and add the concentration of alkali according to Table 8. The aqueous solution of 20% alkali, the amount of alkali added is 0.03% (counted as 0.055g in NaOH) of grease weight, stirred and reacted for 6 hours, filtered respectively, sampling and measuring the content of erythralenone in every part of corn oil after processing, The experimental results are as follows:

Abstract

The invention provides a grease processing technology. By means of operation of making grease make contact with alkali under the condition of 3-25 DEG C, the content of zeranol in grease can be effectively lowered. Compared with the prior art, alkali consumption and neutral oil loss are lower, the production efficiency is higher, and the zeranol removal rate is more excellent.

Description

technical field [0001] The invention relates to the field of oil processing, and relates to an oil refining process, in particular to an oil processing process for reducing erythrenone. Background technique [0002] Zearalenone toxin (Zearalenone, ZEN), also known as zearalenone, F-2 toxin, is a class of compounds with a dihydroxybenzoic acid lactone structure, originally from corn with head blight, it is One of the most widely polluted biological toxins in the world, it has a toxic effect on human health that cannot be ignored. Long-term intake of zearalenone toxins by humans can lead to hyperestrogenism, morphological lesions and dysfunction of reproductive organs, such as abnormal redness and swelling of reproductive organs, persistent estrus symptoms, difficulty in pregnancy, miscarriage, and high frequency of teratogenesis, etc. symptom. [0003] Zearalenone mainly contaminates grains such as corn, wheat, rice, barley, millet and oats. Among them, the positive detect...
