Other names for the additive (synonyms)
General Information
Citric acid esters of mono- and diglycerides of fatty acids (food additive E472c) belong to the group of esters and glycerides of acids (additive E472) and act as emulsifiers and stabilizers in the food industry. This means that additive E472c helps combine water and fat into a uniform homogeneous mass, improves the texture of products, and maintains their structure during storage.
Food additive E472c does not exist in nature in a ready-made form; however, its components — fatty acids, glycerol, and citric acid — are natural substances. Thus, the additive itself is produced technologically, but from components that occur in nature.
Such emulsifiers began to be widely used in the 20th century with the development of industrial production of margarine, baked goods, and sauces. Manufacturers were looking for a substance that would help stabilize product structure and extend shelf life. This led to the development of mono- and diglyceride derivatives, including food additive E472c.
Food additive E472c does not have a single chemical formula, as it is a mixture of compounds. In general, it is formed through the reaction of citric acid with mono- and diglycerides of fatty acids. Physically, it is a waxy or oily substance ranging from light yellow to cream in color, which is well soluble in fats and poorly soluble in water.
For the food industry, additive E472c is produced by combining glycerol and fatty acids (often of plant origin) with citric acid. The process is carried out with temperature control and subsequent purification. After that, the product undergoes quality control and is used in food production.
Effects on the Body
Benefit of Additive E472c
Food additive E472c is not a natural component of the human body and does not perform biological functions. At the same time, its components — fatty acids, glycerol, and citric acid — are familiar to human metabolism.
According to the assessment of the European Food Safety Authority, esters of mono- and diglycerides of fatty acids are hydrolyzed after entering the body into common dietary components — fatty acids, glycerol, and organic acids — which are then incorporated into normal metabolic processes. This means that the body processes them similarly to regular dietary fats.
Risks of Additive E472c
After consumption, food additive E472c is broken down by digestive enzymes. As a result, fatty acids, glycerol, and citric acid are formed, which are then metabolized or used as an energy source. Excess intake, as with regular fats, may contribute to increased caloric intake.
In 2020, EFSA re-evaluated the safety of the E472 group (including food additive E472c) and concluded that there is no need to establish a group acceptable daily intake (ADI) for additives E472a–E472c.
The Joint FAO/WHO Expert Committee on Food Additives (JECFA) previously also noted that mono- and diglycerides of fatty acids and their derivatives do not raise concerns when used within technological needs. The U.S. Food and Drug Administration (FDA) recognizes mono- and diglycerides and their esters as safe when used in accordance with good manufacturing practice (GRAS).
Mild adverse effects (such as stomach discomfort or excess fat intake) may occur only with significant overconsumption, which is unlikely under a normal diet. No specific toxic effects have been identified at typical consumption levels.
Uses
In the food industry, additive E472c is used as an emulsifier, stabilizer, and texture improver. It helps maintain structural uniformity and prevents separation.
It is most commonly used in the production of bakery products, enriched baked goods, margarines, creams, sauces, ice cream, and desserts. In bread, it improves crumb structure and extends freshness; in fat-based products, it ensures a uniform consistency.
Legal Status
In the European Union, food additive E472c is permitted in accordance with Regulation (EU) No 1333/2008 on food additives. EFSA has confirmed its safety under the established conditions of use.
In Ukraine, food additive E472c is permitted in accordance with regulations harmonized with EU legislation.
In the United States, esters of mono- and diglycerides of fatty acids are recognized by the FDA as substances generally recognized as safe (GRAS) when used in accordance with good manufacturing practice.
In Canada, Japan, and most other countries, food additive E472c is also permitted for use in food products within established standards.
