### Nutritional Composition of the HMR Product  
The nutritional composition of the test HMR product, including the proximate analysis, fatty acid content, and amino acid content, is shown in Tables 5-7, respectively. Proximate analysis showed that the test HMR product contained some macro- and micronutrients, including carbohydrates, fat, calcium, fiber, protein, potassium, and iron (Table 5). These \begin{table}

**Treatment** & **Color** & **Aroma** & **Flavor** & **Texture** & **Overall Acceptance** \\ \hline Fresh product & 8.75 \(\pm\) 0.10 \({}^{\text{a}}\) & 8.81 \(\pm\) 0.02 \({}^{\text{a}}\) & 8.82 \(\pm\) 0.07 \({}^{\text{a}}\) & 8.82 \(\pm\) 0.05 \({}^{\text{a}}\) & 8.83 \(\pm\) 0.01 \({}^{\text{a}}\) \\ Quick freezing & 8.73 \(\pm\) 0.04 \({}^{\text{a}}\) & 8.78 \(\pm\) 0.05 \({}^{\text{a}}\) & 8.75 \(\pm\) 0.06 \({}^{\text{a}}\) & 8.79 \(\pm\) 0.04 \({}^{\text{a}}\) & 8.81 \(\pm\) 0.04 \({}^{\text{a}}\) \\ Slow freezing & 8.67 \(\pm\) 0.04 \({}^{\text{a}}\) & 8.74 \(\pm\) 0.04 \({}^{\text{a}}\) & 8.48 \(\pm\) 0.12 \({}^{\text{b}}\) & 8.42 \(\pm\) 0.13 \({}^{\text{b}}\) & 8.80 \(\pm\) 0.04 \({}^{\text{a}}\) \\ \hline \hline \end{tabular} Note: Data are the mean \(\pm\) standard deviation. The means of each sensory property denoted with different superscript letters are significantly different according to [PERSON]’s test (\(p<0.05\)).

Table 3: Effect of roasting process on the chemical characteristics of abalone (_Haliotis discus human_). nutrients are essential for human health and are used as sources of energy in the human body [27]. In addition, the test HMR product contained trans fat that is still acceptable to consume. According to US Food and Drug Administration [28], the daily value of trans fat is 2 g/100 g. Thus, the test HMR product exhibited high nutritional value and contributed to daily nutritional requirements. The total saturated fatty acid content represented the highest proportion of fatty acids in the test HMR product (55.55%), followed by polyunsaturated fatty acids (23.55%) and monounsaturated fatty acids (20.90%). The three most dominant fatty acids were palmitic acid, oleic acid, and linoleic acid, which have known beneficial effects on human health [29]. Moreover, the test HMR product contained omega 3 and omega 6, which indicates that the product is highly nutritious. We also observed EPA, DPA, and DHA in the product, which may contribute to human health by influencing inflammation, neuronal, immune function, retinal, peripheral artery disease, major coronary events, and anticoagulation [30]. Furthermore, omega 6 contributes to maintaining human health by lowering \"bad\" cholesterol levels, reducing total cholesterol levels, raising \"good\" cholesterol levels, and reducing the risk of cancer and heart disease [31]. Thus, the test HMR product exhibits good nutritional value for the human body and can be a source of daily fatty acid requirements. Analysis of the amino acid contents showed that the test HMR products contained both nonessential and essential amino acids (Table 7). The nonessential amino acid content was 11.14% higher than that of essential amino acids. Glutamate, aspartic acid, and arginine were the three most dominant amino acids in the tested HMR product, which are an important source of energy for the immune system [32] and beneficial for human health. According to [PERSON] et al. [33] and [PERSON] et al. [34], glutamate is the dominant amino acid found in fishery products.
