Processing of Defatted Wheat Germ Flour / Powder
The wheat grain contains three main parts, bran, endosperm, and germ. The wheat germ is located at the base of the wheat grain and makes only 2.5% of the weight of wheat grain. New wheat plant germinates from the wheat germ, and therefore it is considered to be the embryo of the seed. (Related Post: Plant Protein Extraction Machine)

- Extract the Wheat Germ
To produce wheat germ flour, the wheat germ should first be extracted from the grain. Once separated from the rest of the grain it is referred to as raw wheat germ.
- Wheat Germ Degreasing / Defatting
Oil is then extracted from the raw wheat germ to produce defatted wheat germ meal. To extract the oil, low temperature subcritical extraction machine is suggested which can completely retain protein nutrition and activity, and it is the best machine for processing high-end wheat germ flour and wheat germ protein powder. Once the cold oil extraction procedure is over, the residue products are so called low temperature extracted wheat germ meal.

Wheat Germ Processing Market
High Protein Value: Theoretically speaking, wheat germ accounts for 2.5% of the grain mass of wheat, 25kg of wheat germ can be produced by processing 1000kg of wheat germ. Defatted wheat germ contains high protein content. About 30% of wheat germ is protein, a form of vegetable protein. Wheat g germ flour is not a complete protein like meat but contains vegetable protein.

Commercial Value of High-end Oil: The oil content of wheat germ is generally 8%-10%, which means 80kg-100kg of crude wheat germ oil can be obtained by processing 1000kg of wheat germ. Due to the lack of resources and the difficulty in processing, wheat germ oil is a kind of high-end oil with high commercial value. It is generally been processed into soft capsules to and sold to global market as health care products.
Application of Defatted Wheat Germ Flour
Depending on preference, the powder can be made available for use in a variety of colors ranging from light brown to dark brown. Since whole wheat germ is more perishable, extracting the oils in the wheat germ makes the flour to last longer. Wheat germ is added to a variety of processed food to enhance nutrition, improve texture, and add flavor. Wheat germ flour is produced due to the ever-increasing need for foods that contain a high level of natural nutrients based on grains. It contains important vitamins like vitamin E, vitamin B, folate, and several minerals including iron, potassium, calcium, zinc, selenium, and phosphorus. White germ flour is also high in fiber, low in fats, and has a unique flavor. It contains numerous amino acids. They include alanine, leucine, lysine, proline, and tyrosine. These amino acids are what compose protein.
Extract Protein from Wheat Germ
Protein is extracted from wheat germ through a process called reverse micelles. Protein can also be extracted from wheat flour using aqueous ethanol at sub-ambient temperatures. There are different kinds of cell-free systems used in producing wheat germ protein. One of the processes is the wheat germ cell-free expression system which combines cell-free system as well as the eukaryotic system. It is suitable for the expression of crucial membrane proteins. When wheat embryos are dried, they store all the translation-related components.
Once germination starts, these components are ready for protein synthesis. Wheat germ contains factors that hinder translation such as thionin, proteases, and ribonucleases. To eliminate these inhibitors, a thorough washing or filtration process is employed. Doing so also eliminates other molecular contaminants ensuring high stability.

Advantages of Wheat Germ Protein
The optimized system provides a great advantage when examined along with other common systems used for cell-free protein expression. The advantages include expressing large molecules, automated purification and expression, efficient protein folding, high solubility, high stability, high success rate, and a high yield. Generally, wheat germ generated proteins have a number of advantages over other proteins in form and structure. It has been observed that they are serum and animal free, also, since they are of eukaryotic origin their complexity in shape is conserved, they have a high solubility owing to the eukaryotic ource and native conformation. The proteins are also significantly stable.
