Comparative Study of Pectin and Kappa‐Carrageenan‐Based Films Loaded With Boswellic Acid and Acetyl‐11‐Keto‐Beta‐Boswellic Acid for Active Packaging

Journal of Food Quality, Volume 2025, Issue 1, 2025.
Active packaging is crucial for extending shelf life, maintaining food quality, and reducing reliance on synthetic preservatives by preventing spoilage, oxidation, and microbial contamination. In this study, boswellic acid (BA) and acetyl‐11‐keto‐beta‐boswellic acid (AKBA) were isolated from the oleo‐gum resin of Boswellia sacra and incorporated into ...
