  • 4. Sauces and Soups Emulsifiers are widely used in sauces (like gravies and hollandaise) and soups to create a homogenous texture that does not separate over time. They contribute to the mouthfeel, making sauces more appealing and creamy, essential for culinary dishes.


  • Isopropyl alcohol is a secondary alcohol, meaning that the hydroxyl group (-OH) is attached to a carbon atom that is connected to two other carbon atoms. It boasts a molecular weight of 60.1 g/mol and an impressive boiling point of 82.6 °C (180.7 °F), which makes it relatively easy to evaporate. Its solubility in water is a notable feature, allowing it to blend well with water and other polar solvents. This property makes isopropyl alcohol an excellent choice for various applications, particularly in cleaning and disinfection.

  • Scientific Evidence and Perspectives


  • Intake dose in food: It is allowed to be used in amounts between 200 mg/kg and 2000 mg/kg in almost all types of food.

  • Potassium Sorbate is a mild preservative being used in cosmetic and skin care formulas as a paraben alternative to prevent or retard the growth of microorganisms and protect products from spoiling. Developed from Sorbic Acid, which is naturally found in the berries of the mountain ash tree, Potassium Sorbate is effective against fungi, mold and yeast, and to a lesser degree bacteria. Potassium Sorbate is also used as a food preservative and is frequently seen as a wine ingredient to increase shelf life and stability. It is FDA approved and not considered toxic. It is also CIR approved. 
  • The transformation of acetic acid to formic acid can involve several chemical processes, one of the most typical being the oxidative decarboxylation of acetic acid. In this reaction, acetic acid undergoes oxidation, where the carbon atom in the carboxyl group loses carbon dioxide (CO₂) upon reacting with oxidizing agents. Subsequently, the remaining structure stabilizes into formic acid. Research has indicated that using catalysts, such as metal oxides, can facilitate this transformation, making it more efficient and commercially viable.

  • What is PGPR?


  • Some molds (notably some Trichoderma and Penicillium strains) and yeasts are able to detoxify sorbates by decarboxylation, producing piperylene (1,3-pentadiene). The pentadiene manifests as a typical odor of kerosene or petroleum.

  • Benzoic acid remains a stalwart in the realm of food preservation, providing a reliable means to enhance the longevity and safety of various products. Its effectiveness, coupled with its low cost and ease of use, makes it an attractive choice for food manufacturers. However, as with all preservatives, it is essential to use benzoic acid responsibly, considering both regulatory guidelines and potential health impacts. As consumers become increasingly health-conscious, the food industry must continue to innovate, possibly exploring natural alternatives while ensuring food safety and quality.


  • The applications of E1100 in food processing are diverse. One of its primary uses is in the baking industry. Adding E1100 to dough can improve its handling properties, enhance fermentation, and ultimately produce a better texture and rise in baked goods. This makes bread softer, prolongs its freshness, and improves overall consumer satisfaction.


  • The importance of primary emulsifiers cannot be overstated, as they ensure the consistency and quality of emulsions. In the food industry, for example, they allow for the creation of stable salad dressings, mayonnaise, and sauces that do not separate over time. In cosmetics, they help formulate creams and lotions that maintain a smooth texture and even distribution of ingredients. In pharmaceuticals, effective emulsifiers are crucial for the development of drug delivery systems that require a stable mixture of oil-based and water-based components.


  • Moreover, regulatory bodies across the globe heavily monitor the use of antimicrobial preservatives in food. In the United States, the Food and Drug Administration (FDA) and the U.S. Department of Agriculture (USDA) set strict guidelines for permissible levels of these substances, ensuring they are used safely and effectively. Similar regulatory frameworks exist in Europe and other regions, emphasizing the importance of scientific evaluation in the application of food additives.


  • Potential Benefits


  • As a food additive, potassium sorbate is used as a preservative in concentrations of 0.025–0.100%, which in a 100 g serving yields an intake of 25–100 mg. In the United States, no more than 0.1% is allowed in fruit butters, jellies, preserves, and related products.
