Introduction of Threonine Solution
Threonine is an essential amino acid that the human body cannot synthesize on its own. It is the third most limiting amino acid in poultry feed, following L-lysine and L-methionine. Threonine is also an important component of protein synthesis and plays a significant role in delaying aging, enhancing immunity, increasing resistance, and preventing diseases. Threonine can be produced through microbial fermentation using glucose derived from the saccharification of starch milk, which is produced from grains such as corn, wheat, and rice.
We provide a full range of engineering services, including project preparatory work, overall design, equipment supply, electrical automation, installation guidance and commissioning.
Threonine Production Process

01
Primary Processing of Grain
Primary Processing of Grain
Starch produced from grain crops such as corn, wheat, or rice is used as raw material and processed through liquefaction and saccharification to obtain glucose.

Cultivation of Microorganisms
Cultivation of Microorganisms
The fermentation environment is adjusted to a suitable condition for the growth of the microorganisms, inoculation and cultivation are carried out, and conditions such as pH, temperature, and aeration are controlled to be appropriate for the growth of the microorganisms.

Separation and Purification
Separation and Purification
In industrial production, ion exchange is commonly used. The fermentation liquid is diluted to a certain concentration, then the pH of the fermentation liquid is adjusted with hydrochloric acid. Threonine is adsorbed by ion exchange resin, and finally, the threonine is eluted from the resin with an eluent to achieve the purpose of concentration and purification. The separated threonine still needs to go through crystallization, dissolution, decolorization, recrystallization, and drying to obtain the final product.

Application Fields of Threonine
Feed Industry
Threonine is often added to feed primarily composed of grains such as wheat and barley to promote the growth of poultry and enhance immune function. It can be widely used in piglet feed, boar feed, broiler feed, shrimp feed, and eel feed, which helps to adjust the amino acid balance in feed, promote growth, improve meat quality, improve the nutritional value of feed ingredients with low amino acid digestibility, and produce low-protein feed.
Food Industry
Threonine, when heated with glucose, easily generates caramel and chocolate flavors, which have a flavor-enhancing effect. Threonine is widely used as a nutritional supplement, can be used to enhance protein nutrition, improve the taste and quality of food, as well as in formulated foods for special populations, such as infant formula, low-protein foods, etc.
Pharmaceutical Industry
Threonine is used for the preparation of amino acid infusions and comprehensive amino acid formulations. Adding an appropriate amount of threonine in food can eliminate the decrease in body weight gain caused by an excess of lysine, and reduce the protein/DNA, RNA/DNA ratios in liver and muscle tissues. Adding threonine can also alleviate the growth inhibition caused by an excess of tryptophan or methionine.

Frequently Asked Questions
Wet Milling Process of Corn Starch
+
These days, cornstarch is made by a process called wet milling.
Routine Use of Purifier
+
In the complete flour mill plant, the flour purifier is an indispensable part. After carefully debugging and operation adjustment, the working condition of the purifier should be patrolled frequently during the production process, which is also very important for the stability of the flour quality and the service life of the flour purifier.
Corn Gluten Meal Usage
+
Corn Gluten Meal is a protein-rich product which extract from maize, with the process of steeping, separating, drying separation and condensing the gluten liquid, drying it.
