Overview

Citric acid is a weak organic acid naturally found in citrus fruits and widely used as a food additive, preservative, and pH regulator in various industrial and pharmaceutical applications. Research published in this journal examines citric acid across multiple contexts, including its role in food science, pharmaceutical formulation, and materials science. Studies have investigated citric acid as a crosslinking agent in novel drug delivery systems designed for colon-targeted therapy, where it modifies polymer carriers to achieve controlled release. In food research, citric acid appears in analyses of antioxidant properties and organic acid content in fruits such as cashew apples, and in the production of nutrient-rich dried food powders from tomatoes and strawberries, where it contributes to acidity profiles and preservation characteristics. Additional work has examined citric acid's presence in athletic beverages and its effects on dental materials, specifically how acidic drink exposure influences the surface properties and fluoride release of glass ionomers. The breadth of this research reflects citric acid's significance as both a naturally occurring compound in plant-based foods and a versatile functional ingredient in pharmaceutical and food technology applications.
