This study was conducted to optimize the processing of seasoned salmon Oncorhynchus keta jerky (SSJ) using response surface methodology (RSM). For seasoning sauces-blending conditions of jerky using the RSM program, salt [X₁, % (w/v)] and amino-basic material [X₂, % (w/v)] were chosen as independent variables, and salinity (Y₁) and amino-N (Y₂) were chosen as dependent variables. The optimum conditions of X₁ and X₂ were 1.2% and 12.9%, respectively. To optimize drying conditions of seasoned salmon jerky using RSM program, soaking time (X₁, min), drying temperature (X₂, ℃) and drying time (X₃, min) were chosen as independent variables, and moisture content (Y₁), hardness (Y₂) and overall acceptance (Y₃) were chosen as dependent variables. Optimum conditions of X₁, X₂ and X₃ were 183.0 min, 62.5℃ and 351.0 min, respectively. In the sensory evaluation, the scores for taste, flavor, and texture for of SSJ were higher than those for a commercial product. The results suggest that the developed seasoned salmon jerky can be industrialized.

This study aims to investigate protein consumption market trends in Korea. Protein consumption was divided according to the protein source into meat, fishery, and plant-based protein. To accomplish the goal of this study, food purchase data from 525 households panels collected by the Rural Development Administration over the last 10 years were used. The results of the study showed an increase or decrease in protein consumption by protein type over the last 10 years, and a reason to explain this change has been suggested. Specifically, this study found a dramatic increase in the consumption of several proteins, including beef sirloin, beef tenderloin, seasoned beef & steak, pork belly, pork shoulder, pork neck, seasoned pork, pork cutlet, sweet and sour pork, canned ham, chicken drumstick, chicken breast, dak gangjeong, Chinese fried chili chicken, salmon, eel, abalone, squid, octopus, webfoot octopus, octopus minor, canned whelk, tofu, cold bean soup,and plant-based milk. Some items showed no increase in consumption (such as beef jerky, pork rib, sausage, bacon, whole raw chicken, cutlass fish, oyster, fish cake, crab stick, surimi sausage,and canned fishery), whereas a few items showed decreased consumption (e.g., mackerel, pollack, cod,and canned tuna)
