Why Does Alanine Need to Be Decolorized?
Whether L-alanine is produced by fermentation or enzymatic methods, the crude product typically contains some colored impurities. These pigments may originate from:
- Fermentation medium components: Maillard reaction products (melanoidins) produced during high-temperature sterilization or fermentation of complex organic materials such as yeast extract and corn steep liquor.
- Microbial metabolites: Pigments or byproducts produced by the microorganisms themselves.
- Protein degradation products: Degradation products of proteins in the culture medium during the process.
These colored impurities (usually large molecular organic pigments, colloidal substances, etc.) will affect the purity and appearance of the final product, so activated carbon needs to be used to remove them in order to meet the high standards of pharmacopoeia, food or cosmetic grades.
Activated Carbon For Decolorization Principle
Activated carbon is a porous carbon material with an extremely large surface area (typically 500-1500 m²/g). Its decolorization function relies primarily on physical adsorption. Through its rich pore structure and surface van der Waals forces, it selectively adsorbs impurities such as colored macromolecules, colloids, and odorous substances from the solution.
Activated carbon has a stronger adsorption capacity for large, less polar colored substances, while it has a relatively weaker adsorption capacity for small, more polar amino acids. L-alanine has a small molecular weight (89.09) and is highly water-soluble (highly polar), thus competing with pigments for adsorption. However, by optimizing the conditions, it is possible to maximize pigment adsorption while retaining alanine.

Heycarbons Bituminous Coal Granular Activated Carbon For Alanine Decolorization
In addition to wood powder activated carbon, bituminous coal-based granular activated carbon and reagglomerated activated carbon can also be used for alanine decolorization.
Coal granular activated carbon specification
- Iodine value: 1000mg/g min.
- 8*30, 12*40 mesh
- Methylene blue: 120-280 mg/g
- Moisture: 5% max.
- Bulk density: 0.45-0.55 g/cm3
- CTC: 40-70
The above are typical parameters of Heycarbons’ coal-based granular activated carbon. We can also customize the parameters of activated carbon according to customer requirements.
Activated Carbon Alanine Decolorization Customer Case
A client requested modified granular activated carbon:
- Size 1-2mm
- Methylene blue ≥ 320mg/g
- Iron content ≤ 0.05%
- Calcium and magnesium content ≤ 0.4%
- Acid soluble substances ≤ 3%
- Backwashing
Based on customer requirements, Heycarbons provides deep activated carbon with coal blending. Due to the deep activation depth, the iodine value is not high. The water capacity is 130%.
Activated Carbon For Alanine Decolorization Process
1. Dilution and pH Adjustment
Dilute the alanine-containing solution to a certain concentration (e.g., 10-15%) to avoid excessive viscosity that could affect adsorption efficiency. Use hydrochloric acid or caustic soda to adjust the pH to near the isoelectric point (pH ≈ 6.0). At the isoelectric point, alanine has the lowest solubility and is electrically neutral, minimizing adsorption by activated carbon, thus reducing losses. However, many pigments may be more readily adsorbed at this pH.
2. Heating
Heat the solution to 70-80°C. Heating reduces viscosity, increases molecular mobility, and speeds up the diffusion of pigments into the pores of the activated carbon, significantly improving decolorization efficiency.
3. Adding Activated Carbon
While stirring, slowly add the desired amount of activated carbon (usually 1%-3% of the dry weight of the solution; the optimal amount should be determined experimentally).
4. Maintaining and Stirring
Maintain the temperature and continue stirring for 30-60 minutes to allow sufficient time for adsorption to reach equilibrium.
5. Filtration
After decolorization, the activated carbon and its adsorbed pigments are completely removed through a plate and frame filter or precision filter element, resulting in a clear, colorless filtrate. This step is critical; residual carbon powder will affect product quality.
Factors Affecting Decolorization Effect of Activated Carbon
• Temperature: The higher the temperature, the better the decolorization effect, but too high a temperature may cause amino acid destruction or the formation of new pigments. 70-80°C is a common range.
• pH: One of the most critical parameters. It must be maintained near the isoelectric point of alanine to minimize product loss.
• Activated carbon dosage: Insufficient decolorization results in incomplete decolorization; excessive use not only increases costs but also leads to increased alanine loss through adsorption. The optimal economic dosage should be determined through “decolorization curve” experiments.
• Contact time: Too short a contact time prevents adsorption from reaching equilibrium; too long a contact time may result in low efficiency and increased energy consumption.
• Feed concentration: Too high a concentration results in high viscosity, slow diffusion, and poor decolorization; too low a concentration results in high energy consumption for subsequent evaporation and concentration. A trade-off is necessary.
Activated Carbon For Alanine Decolorization Industry Applications
Medicines and Health Products
Food Additives
Cosmetics and Personal Care
1. Medicines and Health Products
This is the area where alanine purity requirements are most stringent. Activated carbon decolorization plays an indispensable role here, far more than simply improving appearance; it is a critical process for ensuring safety and efficacy.
Core Requirement: Absolute Purity and Safety
Pharmaceutical-grade alanine must meet the stringent standards of the Chinese Pharmacopoeia, the United States Pharmacopoeia (USP), or the European Pharmacopoeia (EP). These standards not only stipulate a minimum purity limit (typically ≥98.5%), but also clearly define impurities, heavy metals, arsenic salts, microbial limits, and the color and clarity of the solution. Any color deviation may indicate the presence of unknown impurities.
Typical Applications
- Amino Acid Injection: As a key component of complex amino acid infusions, it provides nutritional support for patients undergoing surgery, suffering from liver disease, and undergoing critical care.
- Oral Nutritional Supplement: Used in the production of amino acid capsules, oral solutions, or sports nutrition powders to promote muscle recovery and energy metabolism.
- Pharmaceutical Synthesis Intermediate: Serves as a chiral raw material for the synthesis of higher-end pharmaceuticals.
2. Food Additives
In the food industry, L-alanine, a naturally occurring amino acid, is an important flavor enhancer and nutritional supplement.
Core Requirements: Colorless, odorless, and pure in functionality
Food-grade alanine must comply with standards such as GB 1886.43 (China) or the FCC (US Food Chemicals Codex). Its addition must not alter the food’s original color or flavor profile and must solely contribute to its flavor enhancement (savory, sweet) or nutritional benefits.
Typical Applications
- Flavor Enhancer: Combined with nucleotides (I+G), it significantly enhances the umami flavor of soy sauces, sauces, meat products, soups, and snacks (the “guanylate effect”).
- Sweetener Synthesis: Serves as the core raw material for the synthesis of the high-potency sweetener alitame.
- Nutritional Enhancer: Added to cereals, energy bars, and foods for special medical purposes (FSMPs) to enhance amino acid nutrition.
3. Cosmetics and Personal Care
The cosmetics industry places extremely high demands on the safety, stability, and appearance of raw materials, as they come into direct contact with the skin, and consumers’ first impression of a product is determined by sight and touch.
Core Requirements: Extreme Safety, Stability, and Elegant Appearance
Cosmetic raw materials must comply with the “Cosmetic Safety Technical Specifications” and relevant international standards. They must be non-irritating and non-sensitizing to the skin, and remain stable throughout the product’s shelf life, without discoloration or delamination.
Typical Applications
- Humectants: As the main component of natural moisturizing factor (NMF), they are widely used in serums, creams, and masks to enhance the skin’s ability to retain moisture.
- Skin Conditioners: They possess certain antioxidant properties and can help condition and improve skin feel.
- pH Adjusters: They are used to maintain the acid-base balance of cosmetics.
- Hair Care Ingredients: They are added to shampoos and conditioners to improve hair texture and provide moisturizing effects.
