5 The basic principle of electrical resistance heating (Ohmic heating) is to make the food part of an electric circuit through which current flows. Heat generation occurs within the medium due to its inherent electrical resistance. As heat is generated rather than transferred, there is no theoretical limit on the temperature which can be reached.

6 Problems in Early Development of Ohmic Heating Electrolysis and product contamination Use of unsuitable electrode material Difficulty in ensuring good contact between electrodes and products of complex surface geometry Arcing and scorching of the electrodes Absence of crust texture which may be required for foods such as meat or bread

7 The Practice of Ohmic Heating(1/2) For safety operation, the system was designed with a maximum current density of 4,000 Am -2 and with an applied field strength value in the region of 18.3Vcm -1. The process is more energy efficient than microwave heating, because nearly all of the electrical energy goes into the food as heat. Whereas microwave heating requires no physical contact, however, ohmic heating requires electrodes in good contact with the food.

8 The Practice of Ohmic Heating(2/2) Research at FIRDI had developed a method of heating semi-solid foods, e.g. rice cakes or minced fish gel, with ohmic heating where the food material remain paste-like during heating process to maintain good contact with electrodes. The process when applied 110V or 220V alternative current (60Hz) to the food material (0.6kg) will generate heat to raise temperature of 50 o C within 4 min., while compared to conventional steam cooking a time of 60 minutes is required.

11 Development of Recipes (1) The Traditional Taiwanese food The new concept of rice cakes steamed radish cake The steamed radish cake is a common snack food in Taiwan, and it represents a symbol of good luck so that. It takes much more time to cook in tradition; however, the new technology can shorten processing time effectively. Steamed rice paste with Kimchi Steamed Rice cake with Cantonese curing meat It offers new cooking experiences applied with mixed rice paste and various sauces combined with different food ingredient to develop new products and to reduce cooking time.

12 Development of Recipes (2) The Western cuisine The Terrine Garlic spicy chicken risotto Vegetarian Terrine Chicken Terrine Risotto choose natural garlic and onion mixed with cream sauce and cheese. It only takes 6 minutes to heat and to generate the effects of gratin by the addition of butter and cheese in the formulation without using of oven. Vegetarian terrine and chicken terrine are easy to make and has a rich nutrients. It adapts to be as appetizers or as a side-dish.

13 Development of Recipes (3) Desserts The recipe development of ohmic heating cuisine Cheese cake The making of aromatic cheese cake will need 50 minutes traditionally, and the time can be shortened to 8 minutes with the application of ohmic heating. To date, 5 series of 30 cuisine have developed. Designed different formula and procedures for household cooking, food service and catering. Can Help to establish unique recipes for any application.

Features: Crispy and juicy fried foods in any

16 Microwave assisted frying mechanisms: microwave could interact with molecules directly and generate heat inside while frying more uniform and faster frying Features: Crispy and juicy fried foods in any size 1. Improve frying efficiency of 2.5 times the deep-frying. 2. Reduced 30% to 50% of the frying time. 3. More than 30% savings of oil furnace. 4. Uniform and high quality frying, e.g. 1 ~ 100 fried chicken are the same quality. 5. No more need to defrost frozen, fried with the machine directly within the meat tender and juicy in any size. 16
