Description
E215, also known as sodium ethyl p-hydroxybenzoate, is a food additive belonging to the paraben group, primarily used as an antimicrobial preservative. Its function is to inhibit the growth of molds, yeasts, and bacteria, extending the shelf life of foods.
It is industrially obtained by esterification of p-hydroxybenzoic acid with ethanol, followed by neutralization with sodium hydroxide to form the sodium salt, which is more water-soluble than the free ester. It is a white crystalline powder, odorless or with a slight characteristic odor, soluble in water and slightly soluble in ethanol. Its stability is good under acidic and neutral conditions, but it hydrolyzes in strongly alkaline media.
The history of parabens as preservatives dates back to the early 20th century, and their use in food was approved in the European Union after evaluations by EFSA and the Joint FAO/WHO Expert Committee on Food Additives (JECFA). EFSA established an Acceptable Daily Intake (ADI) of 0-10 mg/kg body weight for the sum of parabens (E214-E219). WHO has also evaluated their safety, concluding they are safe at authorized use levels. Regarding food safety, E215 is considered safe for the general population when consumed within established limits. However, there has been controversy over possible weak estrogenic effects, although human studies have not shown significant risks at permitted doses.
In food labeling, it must appear as "Sodium ethyl p-hydroxybenzoate" or "E215." The overall safety assessment indicates that under authorized conditions of use, the health risk is low.
E215 is used in a variety of processed foods as a preservative to prevent microbial spoilage. According to EC Regulation 1333/2008, it is authorized in categories such as: soups and broths (except canned), sauces and condiments (e.g., mayonnaise, mustard), confectionery products (e.g., fruit jellies, fruit pastes), non-alcoholic flavored drinks, and cereal or potato-based snack products.
In the Spanish market, it can be found in prepared sauces, instant soups, and some industrial bakery products. Maximum use levels vary by category, generally between 300 and 1000 mg/kg. Compared to the FDA, the United States allows the use of parabens in foods but with similar restrictions; Japan also authorizes them, although with stricter limits in some products.
It is important to note that the use of parabens in foods has declined in recent years due to consumer preference for natural preservatives, although they remain legal and safe within established limits.
Documented side effects of E215 are rare and generally mild. Animal studies have shown that very high doses can cause gastrointestinal irritation, but at food use doses, no significant adverse effects have been observed in humans.
The biological mechanism of parabens includes weak estrogenic activity in vitro, but in vivo and epidemiological studies have not demonstrated relevant hormonal effects in humans from dietary exposure. Sensitive populations could include individuals with paraben allergy, although it is extremely rare (less than 1% of the population).
No interactions with medications have been reported at food consumption levels. EFSA and WHO conclude that E215 is safe in authorized amounts, and no chronic side effects have been established. However, some consumer groups prefer to avoid parabens as a precaution, although scientific evidence does not support significant risks.
