Sodium Aspartate – E638

Toxicity: In Review

What is Sodium Aspartate E638

Additive E638, also known as maltodextrin, is a dextrose polymer used in the food industry as a thickener, stabilizer and texturizing agent. It is obtained from the enzymatic hydrolysis of starch, mainly from corn, potatoes or wheat. Maltodextrin comes in the form of a white or slightly yellowish powder, and is soluble in water. It has a smooth and light texture, making it suitable for use in a wide variety of foods such as soups, sauces, ice cream, breads and baked goods, among others. This additive provides a series of technical benefits in the food industry. It acts as a bulking agent, meaning it can increase the volume and consistency of foods without altering their flavor. It can also improve texture, providing a smooth, creamy feel in products such as ice cream and dairy desserts. Additionally, maltodextrin is a fast source of energy, as it is quickly broken down into glucose in the body. For this reason, it is common to find it as an ingredient in energy drinks and sports supplements. It is important to note that maltodextrin is safe for human consumption, as it has been evaluated and approved by food regulatory bodies in different countries. However, some people with gluten intolerance may be sensitive to maltodextrin derived from wheat, so it is necessary to check food labels to avoid its consumption in this case. In summary, the additive E638 or maltodextrin is a dextrose polymer used in the food industry as a thickener, stabilizer and texturizing agent. It provides beneficial technical properties in foods and is safe for human consumption, although some people with gluten intolerance should use caution.

Adverse effects of Sodium Aspartate E638

The additive E638, also known as sodium glutamate, may have adverse effects in some people. Below are the possible adverse effects of the E638 additive

Allergic reactions Some people may be allergic to sodium glutamate and may experience symptoms such as itching, hives, swelling of the face, lips or tongue , difficulty breathing, dizziness or fainting. If you experience an allergic reaction, you should seek medical attention immediately.

Chinese restaurant syndrome Some people may experience a series of symptoms known as “Chinese restaurant syndrome” after consuming foods containing sodium glutamate. Symptoms may include headache, sweating, facial redness, chest pressure, numbness or tingling in the face or neck. These symptoms usually go away on their own within a few hours.

Migraines Sodium glutamate has been linked to triggering migraines in some sensitive people. If you are prone to migraines, it may be advisable to avoid eating foods that contain this additive.

Increased appetite Sodium glutamate has been associated with increased appetite in some people, which can lead to overeating and potentially weight gain.

Nervous system involvement Sodium glutamate can have adverse effects on the nervous system, such as excessive stimulation of brain cells, which can cause symptoms such as headaches, anxiety, dizziness, difficulty falling asleep or mood changes. It is important to note that not all people will experience these adverse effects and that tolerance to sodium glutamate may vary from person to person. If symptoms are experienced after consuming foods with this additive, you may consider limiting your intake or consulting a health professional.

How do you get Sodium Aspartate or E638?

E638 additive, also known as glycyl-l-glutamine dipeptide, can be obtained through different chemical synthesis methods. One of the common methods involves combining the amino acids glycine and glutamine using specific reagents and conditions. Here is a possible synthesis route to obtain the additive E638

Get the necessary amino acids Glycine (Gly) and glutamine (Gln). These can be purchased commercially already synthesized or can be extracted from natural sources.

Prepare an aqueous solution of the amino acids in the appropriate proportions. For example, a solution with a molar concentration of 1 mM glycine and 1 mM glutamine.

Add a dehydrating agent or dehydrating agents, such as acetic anhydride or N-methylimidazole anhydride, to the solution. These agents will help remove water from the reaction and promote the formation of the dipeptide.

Adjust the reaction conditions, such as temperature and reaction time, to favor the formation of the dipeptide. For example, the reaction can be carried out at room temperature for several hours or even at lower temperatures for longer.

Monitor the progress of the reaction using analytical techniques such as thin layer chromatography or high-performance liquid chromatography. These techniques will allow you to detect the formation of the dipeptide and control the purity of the product.

Once the desired conversion has been achieved and the purity of the product has been confirmed, you can stop the reaction and isolate the dipeptide. This can be done using purification techniques such as crystallization, liquid-liquid extraction or chromatography. It is important to note that this is only one of the possible methods to obtain the E638 additive and that other alternative synthesis routes may exist.

Food use of Sodium Aspartate E638

The additive E638, also known as monosodium glutamate, is used in the food industry as a flavor enhancer. It is present in a wide range of food products and has various uses in cooking

Flavor improvement in processed foods E638 is commonly used in processed foods such as instant soups, condiments, salad dressings, sauces, spice mixes, and canned foods to enhance their flavor. It helps bring out the natural flavors of foods and gives them depth and complexity.

Flavor enhancer in meat products It is used in processed meats, such as sausages, sausages, hamburgers and canned meats to enhance their flavor and improve juiciness. It is also added to cured meat products, such as ham, to improve its flavor and aroma.

Enhance flavor in seafood products E638 is used in processed seafood products, such as preserves, soups and fish sauces, to enhance their natural flavor and give them a more intense taste.

Flavor enhancement in prepared dishes It is added to prepared dishes such as noodles, fried rice, pasta-based dishes, instant soup mixes and pre-cooked dishes to increase their flavor and make them more attractive to the palate. It is important to note that E638 may cause adverse reactions in some people, such as headaches, palpitations, and nausea. Therefore, it is recommended to read food product labels and take precautions if you are sensitive to this additive. In any case, it is essential to consume a balanced and varied diet, and limit the intake of processed foods that contain artificial additives such as E638.

Industrial use of Sodium Aspartate E638

The additive E638, known as tripolyphosphate phosphates, has several industrial uses. Below are some of the common applications of this additive

Food industry In the food industry, the E638 additive is used as an adjuvant or stabilizer. It is used in meat products such as sausages and fish products to improve texture and retain moisture. It is also used in baked goods such as bakery and pastry products to improve texture and extend shelf life.
