An electronic 'nose' that can detect whether your food is fresh and safe to eat has been developed.
The device, called Peres, is designed to detect whether a product is fresh, whether it is hazardous to health and whether it carries a risk of food poisoning.
The e-nose enables users to determine the quality and freshness of beef, pork, poultry and fish.
The device is held by the user, over his or her food. The device has four sensors that monitor temperature, humidity, ammonia and volatile organic compounds in the air around the food.
The information is sent to the user's smartphone via Bluetooth. Once it has the data, the app will display recommendations based on the freshness of the food, 'Gizmag' reported.
The sensors in Peres can detect over 100 different volatile organic compounds in food, and many of these are strong indicators of whether or not it is fresh and safe to eat.
