We evaluated the quality characteristics of Kimbugak prepared using a microwave oven or the oil-frying puffing method with different contents (0%, 15% and 30%) of Capsosiphon fulvescens in dried laver. Microwave-processed Kimbugak had lower crude fat content but higher levels of crude ash, crude protein, and minerals than that prepared by oil-frying; it also had higher hardness values. The redness of Kimbugak containing 30% C. fulvescens processed using either method was lower than the control group. In sensory evaluations, participants preferred Kimbugak containing 30% C. fulvescens puffed by oil-frying. These results indicate that Kimbugak puffed using the oil-frying method has the best quality characteristics.
