Embodiment 1

[0019] Include the following steps:

[0020] (1) Corn germ cleaning and impurity removal, low temperature crushing and grinding

[0021] The embryos of ordinary mature corn kernels with a moisture content of 6% obtained by the dry method are subjected to air separation and magnetic separation to remove seed coats, weeds, sandstone and metal impurities, and are used for later use; if the embryos of ordinary mature corn kernels are obtained by a wet method, then Rinse with running water at 6°C to remove inedible impurities. The washing time is 10 minutes, then freeze-dry to a moisture content of 6%, and set aside; add ice chips to the corn germs that have been preliminarily treated as above at a mass percentage of 35%, and use a knife grinder Carry out cutting and crushing to obtain fine corn germ particles with a particle size of 40 mesh, cut and crush with a knife mill for 5 minutes, and the final temperature of the material is 15°C; then immediately carry out grinding and mic...

Embodiment 2

[0029] Include the following steps:

[0030] (1) Corn germ cleaning and impurity removal, low temperature crushing and grinding

[0031] The embryos of ordinary mature corn kernels obtained by the dry method with a moisture content of 7% are subjected to winnowing and magnetic separation to remove seed coats, weeds, sand and metal impurities, and are used for later use; if the embryos of ordinary mature corn kernels are obtained by the wet method, then Rinse with running water at 8°C to remove inedible impurities. The washing time is 20 minutes, then freeze-dry to a moisture content of 7%, and set aside; add ice chips to the corn embryos that have been preliminarily treated as above at a mass percentage of 47%, and use a knife grinder Carry out cutting and crushing to obtain fine corn germ particles with a particle size of 60 mesh. Cut and crush with a knife mill for 10 minutes, and the final temperature of the material is 20°C; then immediately carry out grinding and microniz...

Embodiment 3

[0039] Include the following steps:

[0040] (1) Corn germ cleaning and impurity removal, low temperature crushing and grinding

[0041] The embryos of mature corn kernels with a moisture content of 8% obtained by the dry method are subjected to air separation and magnetic separation to remove seed coats, weeds, sand and metal impurities, and are used for later use; if the embryos of mature corn kernels are obtained by a wet method, 10 Rinse with running water at ℃ to remove inedible impurities. The washing time is 30 minutes, then freeze-dry to a moisture content of 8%, and set aside; add ice chips to the corn germ that has been preliminarily treated as above according to its mass percentage of 60%, and cut it with a knife crusher Crushed to obtain fine corn germ particles with a particle size of 80 mesh, cut and crushed with a knife mill, and the time was 15 minutes, and the final temperature of the material was 25°C; then immediately carried out grinding and micronization t...

Abstract

The invention relates to a corn vital element and a production method thereof, belonging to a food processing technology. The production method comprises the following steps: cleaning corn germs obtained from ripe corn kernels to remove impurities, and carrying out low-temperature crushing and grinding, freeze-thawing and activating, super-high pressure sterilizing, sterile-freeze drying, ultrafine grinding, and the like, so that the activity of natural nutritional ingredients in the corn germs can be maximally preserved and a healthy food containing all nutritional ingredients of the corn germs can be obtained; the healthy food can be directly and individually eaten and also mixed with other foods such as milk powder, rice, and flour for being eaten, and can be blended with water for drinking and also mixed with other drinks for drinking, thus being convenient to eat. The corn germ vital element processed by adopting the technology does not contains any sensitive ingredients, and is suitable for being eaten by any crowd as a nutritional supplement. The corn vital element can not cause pollution or waste during production, and is convenient to operate; an application range of the corn germs during food processing is widened, and a healthy food which is rich in nutrients and convenient to eat is provided.

Description

technical field [0001] The invention belongs to the technical field of food processing. Background technique [0002] Maize, also known as corn, is an annual herbaceous plant in the Gramineae family. It is one of the most widely distributed food crops in the world, and its planting area ranks third after wheat and rice. The planting range is from 58°N (Canada and Russia) to 40°S (South America). my country is the golden belt of corn. Corn is one of the main crops in my country, and its output ranks second in the world. Corn is an important food, feed and chemical raw material in my country. [0003] Corn kernels are mainly composed of cortex, endosperm, germ and root cap. Corn endosperm accounts for 73% to 85% of the mass of corn kernels. The main component is starch, followed by protein. Corn endosperm protein is mainly gliadin, which is not easy to be digested and absorbed by the human body. Maize germ is composed of germ, hypocotyl, radicle and cotyledon (scutellum), l...
