Description
Jiajia Wang and co-authors build a color sensor for food freshness in a 2024 paper. Spoilage shifts the acidity of meat and fish as they age. A fast color read of that shift can warn shops and homes.
Their sensor uses a DNA strand that folds by acidity, plus gold dust that shifts color. On mutton and sea bass kept warm or cold, color change met the eye in a minute. Light reads tracked age and acidity in a straight line. Paired with a standard rot gauge, the read gave a sharp freshness call. The kit needs no labels or lab gear.
