Other names for the additive (synonyms)
General Information
Food additive E444 — sucrose acetate isobutyrate (SAIB) belongs to the category of emulsifiers and stabilizers. It is widely used in the food industry to give products a uniform structure and stability.
By origin, additive E444 is a semi-synthetic compound. It is produced from natural sucrose (sugar derived from beet or cane), which is chemically modified (esterified) by attaching residues of acetic and isobutyric acids.
Additive E444 was first used in the food industry in the mid-20th century to improve the texture and stability of beverages and desserts. Over time, its use expanded to other product categories where uniform mixing of ingredients without separation is required.
The chemical formula of additive E444 is C40H62O19. It is a clear or slightly yellowish viscous liquid with no pronounced odor. Additive E444 is practically insoluble in water but dissolves well in organic solvents and oils. The compound is characterized by high stability to heat and changes in environmental acidity (pH).
For the food industry, additive E444 is obtained through the esterification reaction of sugar (sucrose) with acetic and isobutyric anhydrides in the presence of catalysts. After the reaction, the product is carefully purified by distillation and filtration to remove acid residues, resulting in a pure viscous substance.
Effects on the Body
Benefit of Additive E444
Food additive E444 does not provide direct biological benefits to health because it is not a vitamin or mineral.
In the body, additive E444 undergoes hydrolysis under the action of enzymes (esterases) and is partially metabolized to form sucrose, acetic acid, and isobutyric acid, which are natural participants in metabolic processes. A significant portion of additive E444 is excreted from the body naturally without accumulating in tissues.
According to toxicological studies, additive E444 does not exhibit genotoxic or mutagenic properties and is considered safe for humans when consumed in permitted amounts.
Experts of the European Food Safety Authority (EFSA), during a re-evaluation in 2016, confirmed the high safety profile of additive E444.
Risks of Additive E444
Food additive E444 is considered relatively safe, and no negative effects in humans have been recorded when consumed within permitted amounts.
Numerous studies in rats, dogs, and humans have confirmed the safety of the additive even at doses exceeding established limits.
Some studies suggest that excessive consumption of emulsifiers, including additive E444, may cause mild digestive disturbances such as bloating or diarrhea. In very rare cases, allergic reactions may occur in sensitive individuals. However, these studies concern emulsifier consumption in general rather than specifically additive E444.
The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has established an acceptable daily intake (ADI) of 0–20 mg/kg of body weight.
The expert panel of the European Food Safety Authority (EFSA) concluded that the available data on absorption, distribution, metabolism and excretion, genotoxicity, and carcinogenicity justify revising the recommended acceptable daily intake (ADI) from 10 mg/kg body weight per day, established by the Scientific Committee for Food (SCF) in 1994, to 20 mg/kg body weight per day.
Considering that the ADI is not exceeded in any population group, EFSA also concluded that the use of SAIB (E444) as a food additive at permitted or reported use levels does not raise safety concerns.
Uses
Additive E444 is used in the food industry mainly as a stabilizer and emulsifier. The main areas of application of additive E444 include:
- soft drinks and fruit juices – prevents separation of essential oils and ensures uniform flavor and aroma;
- nectars and syrups – stabilizes mixtures of sugar, water, and aromatic oils;
- desserts and confectionery products – improves texture and consistency;
- flavored beverages with citrus oils – allows essential oils to be evenly distributed in the liquid;
- energy and specialized drinks – maintains the stability of mixtures during long-term storage.
Legal Status
Food additive E444 is legally permitted in most countries of the world and is considered safe when consumed within established limits.
In the European Union, sucrose acetate isobutyrate is permitted as food additive E444 under Regulation (EC) No 1333/2008 on food additives.
In Ukraine, emulsifier E444 is listed as a permitted ingredient in the list of food additives in accordance with European legislation.
In the United States, sucrose acetate isobutyrate is considered “Generally Recognized as Safe” (GRAS) with usage limitations, for example in soft drinks up to 300 mg/kg of the finished product.
