| Summary: | Abalone (<i>Haliotis discus hannai</i>) has high nutritional value and market demand. However, it is generally sold as a raw product, which suffers from lengthy preparation, low commercial value, and a short shelf life. To address these problems, we processed abalone as a home meal replacement (HMR) product using superheated steam and quick freezing technology. Response surface methodology was used to optimize the roasting process. A test HMR product was produced by mixing roasted abalone with honey butter sauce at a ratio of 70:30 (<i>w</i>/<i>w</i>), then evaluated for its physicochemical, biological, and nutritional characteristics and shelf life. Roasting abalone at 220 °C for 2 min resulted in high scores for hardness and overall acceptance. The roasting process successfully maintained the chemical characteristics of abalone, including pH, volatile basic nitrogen, and thiobarbituric acid-reactive substances. The sensory characteristics of the test HMR product were maintained using quick freezing methods. Moreover, nutritional analysis revealed that the test HMR product contained macro- and micronutrients, amino acids, and fatty acids, which could contribute to meeting daily nutritional needs. The estimated shelf life of the product was 30 months. Therefore, this study successfully developed a high-quality HMR product containing abalone.
