Smart Chopsticks

Smart chopsticks

Chinese tech giant Baidu is developing a set of smart chopsticks that relay information concerning food safety. The intelligent utensils feature sensors that light up red if they detect an ingredient or substance that may be dangerous to the diner's health, or blue if the food is safe.

Able to track the chemical make-up of oil and water present within foodstuffs, the smart chopsticks can also monitor a dish's PH levels, temperature and calorie content. Users can sync them with their smartphone to provide further insight into the composition of their food.

As explored in Intelligent Food, technology is increasingly being used to monitor food standards. A further example of this is the 'electronic tongue', developed in Thailand. Able to rate meals according to the authenticity of their ingredients, the robotic tasting machine was developed after former Thai prime minister, Yingluck Shinawatra, observed that Thai food abroad did not compare to homegrown fare.
