Organic selenium rich corn germ meal production method

Abstract

The present invention discloses an organic selenium rich corn germ meal production method which comprises the following steps: (1) fine selecting organic selenium rich corn raw materials; (2) putting the fine selected organic selenium rich corn into a degerminating device to enable the organic selenium rich corn a directional impact under the influence of centrifugal force, and then conducting processes of crushing, separating corn kernels, extracting germs and grinding to separate corn endosperm, germ and brans, and thereby obtaining the organic selenium rich germs, corn grit and corn meal; (3) extracting corn oil in the obtained organic selenium rich germs by aqueous enzymatic extraction, and aging and crushing the remaining corn germ powder into the final organic selenium rich corn germ meal. The organic selenium rich corn germ meal produced according to the present invention is rich in organic selenium and beneficial to human health.

Description

Technical field [0001] The invention relates to the technical field of corn processing, in particular to a processing technology of corn germ flour rich in organic selenium. Background technique [0002] Selenium is a trace element needed by the human body. In the past, selenium was considered to be a toxic trace element, but it is now proven to be an element indispensable to the human body. Selenium and vitamin E are both anti-peroxidants (peroxide is harmful to the human body), and it has also proved that it has a therapeutic effect on children with malnutrition caused by lack of protein and has a resistance to certain possible carcinogens. The main sources of selenium are food and drinking water. The selenium content of animal offal and seafood is higher, while grain content is lower. The selenium content of fruits and vegetables depends on the local soil and water selenium content. [0003] my country is vast and vast, but geographically different. There are rare high-seleni...

Problems solved by technology

[0006] However, the current processing and utilization route of corn resources is mainly based on wet process, that is, the corn is soaked in sulfurous acid and then undergoes a series of operations such as crushing, grinding, and grading, and the starch, protein, germ, skin, etc. Components - process to separate

The advantage of this process is that the components are separated thoroughly, and pure starch and germ can be obtained. However, this wet process also has some shortcomings: large investment, high operating costs, high energy consumption, serious pollution, and the resulting protein and germ. The germ can only be used as a feed material and cannot be eaten

[0007] At the same time, the main corn planting areas in my country, such as Northeast and Shandong, are all selenium-deficient areas, so the selenium content in the growing corn is generally low, which affects the role of selenium as a healthy element in the highly nutritious corn germ. promote

[0008] At present, there are some corn germ powder products on the market, but the process generally adopts wet process, and the selenium content is generally low. Some products achieve selenium enrichment by adding exogenous selenium elements, such as selenium nutrition enhancer sodium selenite, etc. But this method uses inorganic selenium, which is not safe
