Embodiment 1

[0020] Example 1, this example provides a specific method for extracting phenanthrene tincture from corn soaking liquid. First, the corn soaking liquid is used as raw material, and the corn soaking liquid is put into an ion exchange resin tank equipped with anions for adsorption. After the ion exchange resin is saturated with organic phosphorus, it is then eluted with a 1% hydrochloric acid solution to obtain a solution containing organic phosphorus.

[0021] The solution containing organic phosphorus obtained after elution is neutralized with calcium hydroxide solution (calcium hydroxide solution is a sodium hydroxide solution with a mass fraction of 0.3%) to adjust to a pH value of 6.5---7, and after the neutralization reaction is completed, , the finished product liquid is obtained, and then the finished liquid is filtered and dehydrated by a filter press to form a wet calcium phytate filter cake, and finally the wet calcium phytate filter cake is put into a drying room for...

Embodiment 2

[0022] Example 2, this example provides a specific method for extracting phenanthrene tincture from corn soaking liquid. First, the corn soaking liquid is used as raw material, and the corn soaking liquid is put into an ion-exchange resin tank with anions for adsorption. After the ion exchange resin is saturated with organic phosphorus, it is then eluted with a 3% hydrochloric acid solution to obtain a solution containing organic phosphorus.

[0023] The organic phosphorus-containing solution obtained after elution is neutralized with a calcium hydroxide solution (the calcium hydroxide solution is a sodium hydroxide solution with a mass fraction of 0.6%) to adjust to a pH value of 6.5---7, and after the neutralization reaction is completed, , the finished product liquid is obtained, and then the finished liquid is filtered and dehydrated by a filter press to form a wet calcium phytate filter cake, and finally the wet calcium phytate filter cake is put into a drying room for dr...

Abstract

The method discloses a method for extracting calcium-magnesium phytate from corn soaked liquid and belongs to the technical field of starch processing. The method includes the following steps that firstly, ion exchange resin is used for adsorbing organic phosphorus in the corn soaked liquid; secondly, after ion exchange resin adsorption is saturate, the organic phosphorus on the ion exchange resin is washed and removed through a hydrochloric acid solution, and a solution containing phosphorus is obtained; thirdly, a calcium hydroxide solution is added in the solution containing phosphorus so that a neutralization reaction can be performed, and finished product liquid is obtained; fourthly, the finished product liquid is filtered and dried so that calcium phytate finished products can be obtained. Compared with the prior art, the method has the advantages that due to the fact that the organic phosphorus in the corn soaked liquid is adsorbed through the ion exchange resin, the problems that because clear limewater is directly added for a neutralization reaction in a traditional method, a large number of calcium ions exist in a solution, and an evaporator scales and cannot be used are solved, meanwhile, only the organic phosphorus in the corn soaked liquid is reduced after the corn soaked liquid passes the ion exchange resin, no other nutrient component are lost, and the method can also be used for preparing medicine, fermentation and fodder.

Description

technical field [0001] The invention belongs to the technical field of starch processing, in particular to a method for extracting phenanthrene from corn steeping liquid. Background technique [0002] Tincture of phenanthrene, also known as calcium phytate, is a common raw material for pharmaceutical products. Tincture of phenanthrene is used as a nutritional medicine, which can promote metabolism, increase appetite and nutrition, and promote development. It is suitable for the treatment of various diseases of the nervous system, as well as hypotonia, hysteria, neurasthenia, rickets, rickets, anemia, tuberculosis, etc. Calcium magnesium phytate is also used to enrich trace amounts of niobium. [0003] Soaking is the most important process of corn wet milling. After soaking corn, there will be a lot of compound salts in the corn soaking liquid. When these compound salts are added to a certain amount of clarified lime water, the compound salts will react with calcium hydroxid...
