What is Stearic Acid E570

Additive E570, also known as stearic acid, is a chemical compound used in the food industry as a food additive. It is mainly obtained from plant sources such as palm oil, coconut oil or soybean oil. Stearic acid is a saturated fatty acid, meaning it is made up of stearic acid molecules that are fully saturated with hydrogen atoms. The chemical formula of stearic acid is CH3(CH2)16COOH. This additive is mainly used as an antimicrobial and stabilizing agent in foods and food products. It has been shown that stearic acid can help prevent the growth of bacteria and fungi, which helps extend the shelf life of foods. In addition, E570 is also used as an emulsifier, texture improver and coating agent in food products such as dairy, bakery, candy and confectionery products. This additive can improve the texture, stability, appearance and consistency of foods, thus contributing to the quality and attractiveness of the final products. It is important to highlight that the E570 additive has been considered safe for consumption by health authorities, as long as it is used in the permitted quantities and within the established standards. However, some research suggests that excessive consumption of stearic acid can have negative health effects, such as increasing LDL cholesterol (“bad cholesterol”) in the body. In summary, the additive E570, or stearic acid, is a compound used in the food industry as a food additive. Its main functions are as an antimicrobial agent, stabilizer, emulsifier, texture improver and coating agent in various food products. Although it is considered safe for consumption, moderate consumption and within permitted quantities is recommended.

Adverse effects of Stearic Acid E570

The additive E570 is known as stearic acid, which is mainly used in the food industry as an emulsifier, stabilizer and thickener. Although it is considered safe for human consumption in moderate amounts, it may have some adverse effects in some people. Below are some possible adverse effects of the E570 additive

Digestive problemsExcessive consumption of stearic acid can cause stomach upset, nausea, diarrhea and flatulence in some people. This is due to its fatty nature and its ability to affect digestion in large quantities.

Allergies Some people may be allergic to stearic acid. Allergy symptoms can include rashes, itching, swelling of the face or tongue, difficulty breathing, and anaphylaxis in severe cases. People with known allergies to fatty acids should avoid eating foods containing this additive.

Respiratory problems Inhaled exposure to stearic acid dust can cause irritation to the lungs, causing difficulty breathing, coughing, and wheezing in some sensitive individuals.

Interference with nutrient absorption Excessive consumption of stearic acid can affect the absorption of minerals such as calcium, iron and zinc in the body. This can lead to nutritional deficiencies if consumed in large quantities over a long period of time. It is important to note that, in moderate amounts, the E570 additive is considered safe for consumption. However, if you experience any of these adverse effects after consuming foods containing this additive, it is advisable to consult a doctor to obtain a proper diagnosis and avoid its consumption in the future.

How do you get Stearic Acid or E570?

The E570 additive, also known as stearinic acid, is obtained through a process of hydrolysis and hydrogenation of vegetable or animal fats and oils. Here I detail the steps to obtain the E570 additive

Select a source of fats and oils You can choose to use vegetable fats such as palm oil, soybean oil, canola oil, etc. Or, animal fats such as lard.

Hydrolysis This stage consists of breaking down fats into fatty acids and glycerin. To do this, water is added and the mixture is heated to a suitable temperature and pressure.

Separation of glycerin After hydrolysis, the fatty acids are separated from the glycerin. This can be done by decantation or through a distillation process.

Hydrogenation The fatty acids obtained are subjected to a hydrogenation process, in which hydrogen is added at high pressure and temperature. This process helps saturate the carbon bonds, converting unsaturated fatty acids into saturated fatty acids.

Purification The product resulting from hydrogenation is purified to improve its quality and eliminate any remaining impurities.

Cooling and solidification Stearinic acid is cooled to a temperature where it solidifies, resulting in the formation of a white solid substance.

Grinding and packaging Finally, the solid stearinic acid is ground to obtain finer particles and then packaged in suitable containers. Remember that obtaining the E570 additive must be carried out following all applicable standards and regulations in relation to food safety and product quality!

Food use of Stearic Acid E570

The additive E570, also known as stearic acid, has several food uses. Below are some of the most common applications

EmulsifierStearic acid is used as an emulsifier in foods, meaning it can help stabilize oil-water mixtures. It is added to products such as margarine, salad dressings, sauces and creams to help prevent separation of ingredients.

Thickener This additive also acts as a thickener in foods. It helps give a creamier or thicker consistency to products such as ice cream, dairy desserts, pie and pastry fillings, and protein shakes.

Antimicrobial agent Stearic acid has antimicrobial properties and is used to help prevent the proliferation of bacteria and microorganisms in foods. It can be used in meat products such as sausages and sausages, as well as in bakery and confectionery products to extend their shelf life.

Lubricant In the food industry, stearic acid is used as a lubricant in the production of candy and chewing gum. It helps prevent products from sticking to the molds and makes it easier to remove them from the mold. It is important to note that the E570 additive is considered safe for human consumption within the limits established by food regulatory authorities. However, as with any food additive, it is recommended that proper instructions and usage guidelines be followed to ensure safe use and in compliance with local regulations.

Industrial use of Stearic Acid E570

The E570 additive, also known as stearic acid or stearin, is used in various industrial sectors due to its properties and characteristics. Below are some of the most common industrial uses of the E570 additive

Food IndustryStearic acid is safe for human consumption and is used as a food additive. It is used as a stabilizer, thickener and emulsifier in processed foods such as chocolates, candies, margarines, ice cream, bakery products, among others. It is also used as a coating for some foods to prevent them from sticking together.

Cosmetic industry The E570 additive is used in the manufacture of cosmetic and personal care products. It is used as a thickening agent for emulsions and creams, providing a smooth and uniform texture. Additionally, it acts as a stabilizing agent in skin and hair care products.

Pharmaceutical industry Stearic acid is used in the manufacture of medicines as a table agent, that is, to offer strength and facilitate compression of tablets and capsules. Its lubricating properties also help reduce friction between components and facilitate the manufacturing process.

Plastics industry The additive E570 is used in the production of plastics as a release agent that prevents the material from adhering to the molds during the manufacturing process. This property is especially useful in the production of plastic packaging and containers. These are just a few examples of the industrial uses of the E570 additive. It is important to note that before using this additive in any industrial application, the corresponding regulations and standards must be followed to guarantee safety and compliance with quality standards.
