Emulsifiers are substances that help to mix ingredients by reducing the surface tension between them. They contain both hydrophilic (water-attracting) and hydrophobic (water-repelling) properties, which allows them to interact with both oil and water molecules. Common examples of emulsifiers include lecithin (often derived from soybeans or egg yolks), mono- and diglycerides, and polysorbates. These compounds can be found in a myriad of food products, ranging from salad dressings and mayonnaise to ice creams and baked goods.
In the realm of food preservation, calcium chloride has gained attention for its ability to improve brining solutions. It acts as a curing agent, which helps to draw moisture from the food while adding flavor and prolonging its shelf life. For example, pickling uses calcium chloride to create a crunchy texture in pickled cucumbers, ensuring the final product remains crisp and enjoyable for longer periods.
E435 is a non-ionic surfactant and emulsifier that possesses excellent emulsifying properties. It is derived from the esterification of sorbitol with stearic acid, followed by ethoxylation, which introduces ethylene oxide into the molecule. This process gives E435 its unique characteristics, such as hydrophilicity and lipophilicity, allowing it to bridge the gap between water and oil phases. The number 20 in its name signifies the average number of ethylene oxide units added, which enhances its emulsifying capacity.
E325 is the code assigned to sodium lactate, a sodium salt of lactic acid. It is typically derived from the fermentation of carbohydrates, such as corn or sugar beets, through the action of lactic acid bacteria. Sodium lactate appears as a white, crystalline powder or a colorless liquid and is soluble in water. It is considered a safe food additive and is generally recognized as safe (GRAS) by many food regulatory agencies.
