The home meal replacement (HMR) market has attracted significant attention due to COVID-19 pandemic and products that utilize the combination of different processed ingredients are now being developed. In this study, Broughton's ribbed ark Scapharca broughtonii was soaked in seasoned soy sauce with the incorporation of mustard leaf Brassica juncea (M-BRA), which is known to have a unique texture as well as excellent functional properties such as antioxidation, to develop a regional specialty product. The optimal conditions for manufacturing M-BRA from the seasoned soy sauce (the sauce to be added [X₁] and the soaking time [X₂]), were examined using response surface methodology (RSM) to analyze the significance of the salinity (Y₁), amino-N content (Y₂), and overall acceptance (Y₃). The coefficient of determination (R²) between X₁-X₂ and Y₁-Y₃ were close to 1, thereby confirming the suitability of the RSM model. The optimal conditions were seasoned soy sauce addition of 140% and soaking time of 156 min. The M-BRA manufactured under these conditions exhibited superior overall acceptance compared to seasoned commercial soy sauce, which was used as a control. We expect that the market for M-BRA manufactured by combining marine and agricultural materials will expand owing to superior overall acceptance compared with commercial products.

Surimi has been widely investigated for developing fish snacks; however, few studies have examined the optimal drying conditions of surimi for fish snacks. This study used a response surface methodology to optimize the drying conditions for the overall acceptance of fish snacks. The drying temperature (X₁, 51-65℃) and drying time (X₂, 1.5-2.5 h) were chosen as independent variables. The dependent variables were overall acceptance (Y₁, points), hardness (Y₂, N), moisture content of the dried intermediate product (Y₃, %), and volatile basic nitrogen of the fried final product (Y₄, mg/100 g). The estimated optimal conditions for overall acceptance (Y₁) were X₁=64℃ and X₂=2 h. The predicted values of the dependent variables at the optimal conditions were overall acceptance (Y₁)=8.60 points, hardness (Y₂)=10.07 N, and moisture content of the dried intermediate product (Y₃)=10.00% and were similar to the experimental values. Scanning electron microscopy images revealed that the drying conditions affected the microstructure of the fish snacks. Our results could be used to increase the productivity of fish snacks made by small- and mid-sized seafood companies.

The pacific oyster Crassostrea gigas has a desirable taste and flavor that differs from those of other fish and shellfish. In order to develop a high value-added product from individually quick-frozen oyster extract (IQFOE), we prepared an oyster granular flavor seasoning (OGS) from IQFOE and characterized its qualities. The OGS was prepared by granular molding and fluidized bed drying with inosine monophosphate (IMP, 0.1%), yeast extract powder (1.4%), tangle extract powder (0.6%), monosodium glutamate (MSG, 5.0%), microcrystalline cellulose (0.6%), lactose (27.5%), salt (33.0%), spray-dried IQFOE (22.5%) as a powdered materials, and IQFOE ($Brix\;25^{\circ}$, 7.0%), soy sauce (0.4%) and water (1.7%) as a liquid materials. The moisture, crude protein, pH and salinity of the OGS were 3.4%, 12.5%, 6.50 and 32.0%, respectively. Especially, the OGS revealed very higher amino-N content (1,856.0 mg/100 g) than that (1,291.2-1,610.2 mg/100 g) of other commercial flavor seasonings. In taste-active compounds, free amino acid contents was 1,359.0 mg/100 g, and major ones were glutamic acid, taurine, hydroxyproline, glycine, lysine, phosphoserine, proline in order. And OGS showed good organoleptic qualities for taste, odor and general preference compared with commercial flavor seasonings on a local market.

This study aimed to develop a new commercialization model for theindustrialization of head family food as a gentry families' complex food culture product. We tried to develop a head family food and propose a city sightseeing style's head family product by interviews with 'Hakindang' as the center, the head house of the Suwon Baek clan, and Injaegong group in Jeonjoo. Hakindang (in Jeonju) was confirmed as an improved model Korean-style house in the enlightenment period and the twentieth style modern head family as emerging capitalist. Hakindangsupported independence war funds in the Japanese colonial era and was widely known as gate of filial piety in Jeonju. Representative seasonal foods of Hakindang include pan-fried sweet rice cake with flower petals in the spring, hot spicy meat stew and polypus variabilis in summer, hanchae in autumn, and napa cabbage kimchi with salted flatfish seafood in the winter. When parents-in-law had a birthday, there were party noodles, sliced abalone stuffed with pine nuts, brass chafing dish, fish eggs, slices of blilde meat, and matnaji. Daily, there were mainly salted seafood, slices of raw fish, grilled short rib patties, braised fish, baked fish, syruped chestnut, grilled deodeok root, bean sprouts, radish preserved with salt, dongchimi, soy sauce-marinated horseshoe crab, butterbur, perilla seed stew, salted clams, raw bamboo shoot, agar, fried kelp, etc. The most basic virtue of the head family is filial duty, and they developed mosim dining as a representative food of Hakingdang's head family. The mosim menu is composed of 65% carbohydrates, 20% protein, and 15% fat because it is table for parents-in-law like more than 75 years old. The sensory evaluation showed a chewy texture that is easily swallowed.

The principal objective of this study was to analyze Swede's perceptions of Asian food using a means-end chain method, which may contribute to our understanding of new markets for a food industry interested in globalizing Korean food. With the Means-end chain method, one can determine the cognitive structures built in consumer's minds, which are developed by connecting attributes of product, consequences, and values. The attributes of Asian food that are most positively perceived by Swedes are 'fresh vegetables', 'low-fat', 'light meat and seafood', 'exotic ingredients', 'not expensive' and 'unknown food'. The consequences of eating Asian food connected to these attributes are 'healthy', 'tasty', 'good way to save money' and 'curious'. Finally, Swedes expect to enjoy a value of 'achievement' at the end. Based on the result that 'unknown food' attribute is connected to 'achievement' value, Swedes are assumed to be attracted by the fact that Korean food is 'unknown food'. However, the effect of the 'unknown food' attribute will fade away with time; therefore, stressing Korean food's status as a 'healthy' food, which can be attributed to its use of 'fresh vegetable' and 'light meat and seafood' ingredients and 'low fat' cooking method may be effective as a long-term strategy for making Korean food attractive. The 'healthy' consequence is connected to Swedes' perception of the value 'achievement' and simultaneously to their perception of the value 'belonging and love/sense of belonging'.

Shell waste from the butter clam Saxidomus purpuratus and littleneck clam Ruditapes philippinarum is a large by-product of shellfish aquaculture, and it is desirable to convert it into value-added products for industrial applications. In this study, calcium carbonate (CaC) polymorphs from butter clam (BCSP) and littleneck clam (LCSP) shell powders and commercial CaC were characterized using Fourier transmission infrared spectroscopy (FT-IR), X-ray diffraction (XRD), and scanning electron microscopy (SEM). The results revealed that the optimal calcination conditions to eliminate organic substances and improve solubility for both BCSP and LCSP were $800^{\circ}C$ for 8 h in an electrical furnace. Calcination improved the white index of the butter clam (BCCP) and littleneck clam (LCCP) calcined powder compared with shell powders. The calcium content in BCCP (51.1%) was higher than that of LCCP (44.9%) or commercial calcium oxide (CaO, 44.7%). The XRD patterns of BCCP and LCCP were similar to that of CaO. Cubic-like crystals of CaC and irregular crystals of BCCP and LCCP were observed by SEM. The FT-IR and XRD analyses revealed the presence of calcite and aragonite in the BCSP and aragonite in the LCSP, whereas the CaC contained calcite. These results indicate that butter and littleneck clam shells are potential biomass resources for calcium carbonate and calcium oxide.

The purpose of this study is to test the effects of electrolyzed water treatment on dried-laver Pyropia sp. processing facilities to control microbial contamination. Following the progression of the process to the next step, as well as during the lapse between process operating hours, the contamination level of total viable cell counts (TVC) and total coliform (TC) of laver increased. The TVC increased during the aging step, and after the molding-drying steps were completed, it increased by approximately 2.0 log CFU (colony forming unit)/g. Freshwater used for processing in April had a TVC of 4.31 log CFU/mL, which was more polluted than 2.61 log CFU/mL of seawater. Electrolyzed water was used to treat the sponge used in the laver-molding process, which resulted in a 2 log CFU/mL decrease.The TVC of dried-laver decreased by 1 to 2 log CFU/g when electrolyzed water was applied to the process. In conclusion, application of electrolyzed water in dried-laver processing was shown to be effective in reducing the microbiological contamination of the final product.
