Calcium Citrates – E333

Toxicity: Low

What is Calcium Citrates E333

Additive E333, also known as trisodium citrate, is a trisodium salt of citric acid. It is a food additive commonly used in the food industry as an acidity regulator. E333 is obtained from citric acid, which is a natural organic acid present in many citrus fruits such as lemons, oranges and grapefruits. Through a chemical reaction, trisodium citrate is formed, which has similar properties to citric acid. This additive is mainly used to adjust and control the pH of foods. It acts as an acidity regulator, as it helps maintain an adequate acidity level in food products. This is especially important in processed foods where it may be necessary to maintain a stable pH to ensure safety and extend shelf life. In addition to its role as an acidity regulator, E333 is also used as a metal sequestering agent, meaning it can form complexes with certain metals and prevent their unwanted action in foods. This is especially important in canned products, where it can prevent discoloration or deterioration caused by the interaction of metals present in the can with the food. The additive E333 is considered safe for human consumption, provided it is used in the quantities specified by food regulatory authorities. It can be present in a wide variety of food products, such as beverages, dairy products, desserts, bakery products and preserves. It is important to note that while trisodium citrate is safe for most people, some people may be sensitive or intolerant to this additive. If you have food allergies or intolerances, it is recommended to read product labels and consult a health professional before consuming foods containing the additive E333.

Adverse effects of Calcium Citrates E333

The additive E333, also known as tricalcium orthophosphate, is used as an acidity regulator in various foods and beverages. Although it is generally considered safe for human consumption, some studies have found possible adverse effects associated with excessive use. These effects include

Digestive problems Excessive consumption of E333 can cause stomach upset, nausea, vomiting and diarrhea in some people. This is because tricalcium orthophosphate can trigger an adverse reaction in the gastrointestinal tract.

Bone demineralization In extreme cases of excessive consumption of E333, a possible increase in the loss of minerals such as calcium in the bones has been observed. This can lead to bone demineralization and increase the risk of osteoporosis in susceptible people.

Interference with mineral absorption E333 can also limit the absorption of essential minerals such as iron and zinc in the body. This can lead to nutritional deficiencies if consumed in large quantities over a long period of time.

Allergic reactions Although rare, some people may experience allergic reactions to consuming E33

This can manifest as skin rashes, itching, swelling in the mouth, or difficulty breathing. If you experience any of these symptoms after consuming foods containing E333, it is important to seek medical attention immediately. It is important to note that the adverse effects described above are usually associated with excessive consumption of E33

In moderate amounts and within the limits established by health authorities, this additive is considered safe for most people. However, if you have any concerns or pre-existing medical conditions, it is always advisable to consult a health professional before consuming foods containing this additive.

How do you get Calcium Citrates or E333?

The additive E333 is obtained from the extraction and processing of limestone, which is a sedimentary rock composed mainly of calcium carbonate (CaCO3). The process of obtaining this additive is detailed below

Extraction of limestone The extraction of limestone from quarries or mines is carried out. This rock is found in underground layers or strata.

Crushing and grinding The extracted limestone is crushed and ground into a fine powder. This process is carried out using crushers and mills, with the aim of reducing the size of the particles.

Calcification Limestone powder undergoes a calcification process, which involves heating it to high temperatures (approximately 900-1000 degrees Celsius) in special ovens. During this process, calcium carbonate breaks down into calcium oxide (CaO) and carbon dioxide (CO2).

Hydration and precipitation The calcium oxide obtained is mixed with water, producing calcium hydroxide (Ca(OH)2). Next, a precipitation reaction is carried out using phosphoric acid salts (such as sodium phosphate or potassium phosphate), which results in obtaining the additive E333, also known as tricalcium phosphate. Once the E333 additive has been obtained, it is used in food products and other products that require its properties as an acidity regulator, antioxidant, conditioning agent, among others. It is important to note that this production process may vary slightly depending on the manufacturer and the specifications of the particular E333 additive.

Food use of Calcium Citrates E333

The additive E333, also known as trisodium citrate, has several food uses. These include

Acidity RegulatorTrisodium citrate is used as an acidity regulator in several processed foods. It acts as a buffer, balancing and controlling acidity in food products such as carbonated drinks, jams, dairy products and canned foods.

Stabilizer This additive is also used as a stabilizer in food products, especially in dairy products such as ice cream, milk powder and yogurt. Helps prevent the separation of liquids and solids, providing a smooth and homogeneous texture.

Emulsifying agent Trisodium citrate is sometimes used as an emulsifying agent in foods, allowing fatty and watery ingredients to mix effectively. This is used in products such as sauces, salad dressings and baked goods, helping to maintain proper consistency and texture. It is important to keep in mind that the use of the E333 additive is regulated by food safety authorities, and maximum limits allowed for its use in different foods are established. Additionally, some people may have sensitivity or allergies to this additive, so it is always advisable to read food labels and consult a specialist if you have any questions or concerns.

Industrial use of Calcium Citrates E333

The additive E333, also known as trisodium citrate, has several industrial uses. These are some of the most common applications

Food industry E333 is used as an acidity regulator and stabilizer in foods. It is used in the manufacture of beverages, dairy products, bakery products, meat products and other processed foods. Helps maintain proper pH, improve texture and stabilize emulsions.

Pharmaceutical industry Trisodium citrate is used in the manufacture of medications and supplements due to its ability to improve the solubility of certain compounds. It is also used as a buffering agent, helping to maintain the proper pH of pharmaceutical formulations.

Cosmetic industry E333 is used in cosmetic products such as shampoos, creams and lotions due to its ability to adjust and maintain the pH of the products. It can also act as a chelating agent to improve the stability of products.

Cleaning products industry Trisodium citrate is used as an ingredient in cleaning products, such as detergents and fabric softeners. Helps remove stains and improve cleaning action. These are just some of the industrial uses of the E33 additive. It is important to note that you must always comply with the regulations and standards in force in each country to guarantee proper and safe use of this additive.

Recommended consumption of Calcium Citrates E333

The maximum recommended consumption of the additive E333, also known as calcium salts of orthophosphoric acid, may vary depending on the legislation of each country. In general, an acceptable daily intake (ADI) is established as a reference for the safe amount of additive that can be consumed. In the European Union, the European Food Safety Authority (EFSA) has established an ADI of 70 mg/kg body weight per day for calcium phosphates in general, without specifying a specific figure for the additive E333. Importantly, the ADI refers to a long-term safe daily amount, but other considerations may need to be taken into account, such as the amount of additive present in a specific food and whether it is consumed regularly or sporadically. In any case, it is recommended to read the labels of processed foods and follow the recommendations of the health authorities of each country to ensure adequate consumption of additives and maintain a balanced and healthy diet.
