Descrizione

Applicazioni

• Novel pH-responsive indicator films based on bromothymol blue-anchored chitin for shrimp freshness monitoring: This study presents innovative pH-sensitive films that incorporate bromothymol blue into chitin, designed for tracking shrimp spoilage. The development and testing of these films in real-time scenarios offer a viable method for monitoring seafood freshness, ensuring quality control in food distribution chains (Yang et al., 2023).
