Researchers at UNSW have developed `VibMilk,` a smartphone-based method to detect spoiled milk,using its vibration motor and sensors.

VibMilk analyses milk`s physical changes, like density and viscosity, caused by spoilage. Using machine learning, it predicts freshness with up to 98.35% accuracy, even without opening the container.

Unlike expiration dates, VibMilk provides real-time freshness checks, reducing food waste and the risk of spoilage. It could soon become a practical tool for everyday use.
