Dulcioic acid is primarily used in the development of flavoring agents due to its unique sweet-tart profile. It serves as an intermediate in the synthesis of natural-identical aroma compounds, especially in fruit-flavored food products and beverages. Its structural properties make it suitable for modifying taste perception, enhancing sweetness without adding sugar, which is beneficial in low-calorie and diabetic-friendly formulations. Additionally, dulcioic acid derivatives are explored in pharmaceutical research for their potential metabolic stability and bioavailability enhancement in prodrug designs. It is also utilized in cosmetic formulations for its mild acidity, helping to adjust and maintain pH balance in skincare products.
