RFID tags certainly don’t seem to have anything to do with delicious food. But soon, the technology may come in handy when trying to create a recipe. A patent filed by LG uses RF tags to digitally expand the pages of a conventional cookbook. The project is aimed at assisting regular cooks in discovering or experimenting with a wider variety of foods.
The idea is a simple one. RF tags are embedded in the pages of a cookbook and identify the ingredient or food being used in a recipe. These tags can be read by a terminal station, which could hypothetically be an oven or refrigerator with an RF reader. This station ideally connects wirelessly to a server, which contains a library of information on the food being used. Info- like recipes or valuable cooking tips can be accessed without having to fill the physical pages of the book. Other kitchen appliances can also be tagged and their specs can be read and factored into the cooking process to facilitate the success of the recipe.
Eventually, communication between appliances according to recipes could unleash the full potential of this technology. The Internet of Things, along with RFID could make sure that you never overcook or undercook your roast by informing the oven with the proper cooking temperature and duration, though this is not part of the patent.
Details about where exactly the information is stored, how much on the RF tag and how or from where additional info is retrieved are being worked out to maximize the efficiency of the process. No such book has yet been printed but the patent suggests many systems will be tested. The physical limitations of cookbooks may soon be a thing of the past and, hopefully, poorly executed recipes will go along with them.
