Despite its wide usage, E223 isn't without controversy. The safety of sodium metabisulfite has been the subject of extensive research, particularly concerning its potential to cause allergic reactions. Some individuals, especially those with asthma or sulfite sensitivity, may experience allergic reactions that can range from mild to severe. Symptoms may include respiratory distress, hives, or dermatitis.

Applications of Propargyl Alcohol

Potassium sorbate is the common name for potassium (2E,4E)-2,4-hexadienoate. The main use of potassium sorbate is as food additive (E 202) as mold and yeast inhibitor. Potassium sorbate (E 202) is used as a antimicrobial and fungistatic agent and preservative in foods, especially cheeses (unripen, ripened and whey cheese and cheese products), citrus fruits, chewing gum, processed potato products, potato gnocchi, meat pâté, processed meat, processed fish, processed eggs (dehydrated and concentrated frozen eggs), table-top sweeteners in liquid form, protein products, dietary foods for weight control, salads, fruit nectars, beer, wine, fruit wine and made wine, mead, aromatized wines and aromatized wine-based drinks and cocktails, potato-, cereal-, flour- or starch-based snacks, desserts and food supplements and processed nuts. Potassium sorbate has been also used as medication and in cosmetics and pharmaceuticals. Potassium sorbate is also approved as a biocidal active substance.

Moreover, the demand for clean labels—products that disclose all ingredients transparently and do not contain artificial additives—has surged. Many companies are reformulating their products to meet these consumer preferences, opting for natural preservation techniques while maintaining product safety and quality.

3. Stability Enhancement PGPR contributes to the long-term stability of emulsified products. In chocolates, it helps to reduce fat bloom—a phenomenon where fat crystals rise to the surface, leading to an unappealing whitish appearance. By maintaining a stable emulsion, PGPR prolongs the shelf life and visual appeal of chocolate products.
