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.
E501 is the food additive code for potassium carbonate, a white, hygroscopic salt that is highly soluble in water. It is commonly used as a food additive due to its ability to regulate acidity and act as a stabilizing agent. Its chemical formula is K2CO3, and it is often found in products such as baking powders, noodles, and some processed foods. In addition to its role in food, potassium carbonate is also utilized in various industrial applications, including glass manufacturing and as a cleaning agent.
In the food industry, carnauba wax is often employed as a glazing agent to enhance the visual appeal and texture of various products. For instance, it is frequently used to coat confections, fruits, and vegetables. The application of this wax not only results in a glossy finish but also acts as a moisture barrier, extending the shelf life of the products. It prevents water loss in fruits and vegetables, keeping them fresh longer while maintaining their aesthetic appeal. Thanks to its natural origin, it offers a safe alternative to synthetic glazing agents that may pose health risks.
