What is Glycine and its Sodium Salts E640

E640 additive, also known as glycine and monosodium, is a food additive used in the food industry to improve the flavor and palatability of processed foods. It is a non-essential amino acid that is found naturally in some foods, but can also be produced synthetically. E640 is especially known for its ability to enhance the flavor of monosodium glutamate (E621), another additive used as a flavor enhancer. Together, these additives are used in a wide range of processed foods, such as soups, sauces, dressings, snacks, and ready meals. This additive is considered safe for human consumption, as long as it is within the limits established by health authorities. However, some people may be sensitive to this additive and experience adverse reactions such as headaches, nausea, or upset stomach. It is important to keep in mind that the use of food additives such as E640 is regulated by the competent authorities in each country, and the limits of use and permitted concentrations in foods are indicated. Additionally, these additives must be labeled on food packaging to inform consumers of their presence. In conclusion, the additive E640 is a flavor enhancer used in the food industry to improve the taste of processed foods. While it is considered safe when consumed within established limits, it is important to consume it in moderation and read food labels for its presence.

How do you get Glycine and its Sodium Salts or E640?

The additive E640, also known as glycine and glutamic acid sodium salt, is obtained through a fermentation process. Below is how you can obtain it

Culturing bacteria You start by growing a specific strain of bacteria, such as Escherichia coli, in a nutrient-rich culture medium.

Fermentation Bacteria are incubated under controlled conditions of temperature and humidity for a certain period of time to allow their growth and production of glutamic acid.

Extraction of glutamic acid Once the bacteria have generated a sufficient amount of glutamic acid, they proceed to extract it from the culture medium. This can be done using different techniques, such as filtering or centrifugation.

Neutralization and addition of glycine The glutamic acid obtained is neutralized by the addition of sodium hydroxide (NaOH) to form the sodium salt. Then, glycine (non-essential amino acid) is added as a co-additive to obtain E640.

Purification and drying The E640 additive obtained undergoes a purification process to eliminate impurities and ensure its quality. Subsequently, the product is dried to obtain it in the form of a crystalline powder. It is important to note that the production process of the E640 additive may vary depending on the manufacturer and the legislation of each country regarding food safety and quality standards.

Food use of Glycine and its Sodium Salts E640

The additive E640, also known as glycine or L-glycine, is used in the food industry for several reasons. Below are some of the food uses of E640 additive

Flavor Enhancer Glycine is used as a flavor enhancer in a variety of processed foods such as soups, sauces, salad dressings and canned foods. It helps enhance the flavor of other ingredients present in said foods.

Sweetener Glycine is also used as a sweetener in some food products, as it has a mild sweet flavor. It is sometimes used in conjunction with other natural or artificial sweeteners to provide a balanced sweet taste.

Stabilizer for meat products Glycine can be used as a stabilizer in processed meat products, such as sausages and sausages. Helps improve the texture and stability of said products.

Baked products quality improver Glycine is often used as a quality improver in baked products, such as breads and bakery products. It helps to improve the texture, flavor and conservation of these products.

Acidifying agent In some foods and beverages, glycine is used as an acidifying agent to adjust pH and balance flavor. It can be found in carbonated drinks, juices, soft drinks, and processed foods. It is important to note that while the E640 additive is approved for use in foods by regulatory authorities, such as the United States Food and Drug Administration (FDA) and the European Safety Authority (EFSA), it is recommended to consume it in moderation, since excessive consumption of processed foods and additives can have negative effects on health. It is always important to read product labels and eat a balanced and varied diet.

Industrial use of Glycine and its Sodium Salts E640

The additive E640, also known as glycine, has various industrial uses. Here are some common applications

Food Industry Glycine is used as a flavor enhancer in processed foods and beverages. It helps enhance the flavors of other ingredients, especially in savory products such as soups, sauces, marinades, and appetizers.

Pharmaceutical Glycine is an essential component in the manufacture of medications and supplements. It is used in the production of tablets and capsules as it acts as a binder and flow agent, helping to hold the particles together and facilitating their processing.

Recommended consumption of Glycine and its Sodium Salts E640

The additive E640, also known as glycine or aminoacetic acid, is a food additive used in industry to enhance the flavor of foods. The European Food Safety Authority (EFSA) has established a maximum recommended consumption for this additive. According to the EFSA, the maximum recommended intake of glycine is 2.6 grams per kilogram of body weight per day. This means that a 70 kg person should consume no more than 182 grams of glycine per day. It is important to note that this maximum recommended intake is for the additive in its pure form, and does not take into account the amounts present in processed foods. Therefore, it is important to read the labels of food products to know the amount of E640 additive present in them and adjust consumption accordingly. Additionally, it is important to keep in mind that each person may have different tolerances and sensitivities to food additives. Therefore, if you have any concerns or questions about the consumption of this additive, we recommend that you consult a health professional or nutritionist. In summary, the maximum recommended consumption of the additive E640, glycine or aminoacetic acid, is 2.6 grams per kilogram of body weight per day, but it is important to read the labels of processed foods to control the amount consumed. It is always advisable to consult a health professional or nutritionist if you have any specific concerns.
