- •
A DNA-based sensor was developed for the TAC quantification in beverages.
- •
RNOS was used to induce lesions onto DNA-based material.
- •
Ascorbic acid has the ability to scavenge RNOS and protect DNA.
- •
TAC was measured through sensor and conventional methods.
- •
The DNA-based sensor is suitable for TAC determination in food juice matrices.
