The taste of food plays a big role in the kind of foods we consume. For people who do not have any pressing health issues, it can play a bigger role than the nutritional components of the food. Since the tongue and other parts of the mouth are sensitive to electricity. This idea proposes the use of electricity-based flavors and the development of procedures that involve electrically charging food products as a cooking process.
A possible approach to manufacturing electrically charged flavors is to embed different sides of small grains of edible insulators with small electric charges that will get neutralized to produce small currents that can be sensed by the tongue when they are eaten. The insulating material will be something that dissolves in the mouth or liberates the charges when crushed by chewing.
Some foods that are layered can have alternating layers covered in alternating charges so that the charges are neutralized when the food is eaten.
Candies can have charges embedded on different parts to produce a similar effect when it is consumed. Electrical glazing of food can be developed as a standard process for treating foods too.
Another possible use of electric charges is to use them to heat canned foods. The charges are stored in small capacitors that are placed in the can so that they are neutralized when the can is opened to generate heat. This form of heating can improve the appeal of canned foods like ramen and some cereals that usually have to be taken with warm water.
