The application for the patent was published on September 18, 2026, under issue no. 38/2026.

Abstract: This invention relates to the development of a dual-indicator smart capsule designed for real-time detection of food freshness and spoilage. The capsule utilizes sodium alginate as a biopolymeric encapsulating material, incorporating turmeric extract as a pH-responsive yellow indicator and red cabbage extract as a broad-range anthocyanin-based colorimetric indicator. The dual-indicator system provides a more accurate and reliable visualization of spoilage by displaying distinct color changes under varying pH conditions typically associated with food degradation. The capsule is safe, edible, biodegradable, and suitable for direct integration into food packaging systems. This innovation provides a cost-effective, eco-friendly, and consumer-friendly solution for monitoring food quality, reducing foodborne illness, and minimizing food wastage.
