Surimi has been traditionally used as the main ingredient in gelling foods, such as imitation crab sticks. However, it can also be used to manufacture snacks without gelling properties. To assess the properties of surimi as a snack ingredient, we prepared fried fish snacks with different surimi grades of Alaska pollack (AP) and threadfin bream (TB) and evaluated their quality characteristics. AP had significantly higher protein and gel strength values than TB did. Regarding color, TB showed significantly lower lightness (L) values and higher redness (a) and yellowness (b) values than AP did, consistent with the appearance of a brown color. TB had significantly lower hardness values, higher thickness expansion, and higher oil content than AP did. Hardness was found to be positively correlated with gel strength and negatively correlated with oil content. In the micro-structure images, more blistering was formed in TB, indicating higher expansion and crispiness. In the sensory evaluation, TB showed higher overall sensory acceptance than AP did, which is the result of its high color content, crispiness, taste, and aroma. Principal component analysis of the electronic nose and tongue revealed that the samples were clearly separated. In particular, TB had more aromatic components than AP in the electronic tongue. Our findings indicate that gel strength, which determines the quality properties of surimi, does not need to be considered in snack manufacturing. In fact, surimi with low gel strength is a more suitable ingredient for snack manufacturing.

The purpose of this study was to identify U.S. consumers' preferences for Bibimbap and to determine whether or not Bibimbap can be adopted into the American palate. A total of 214 people tasted a controlled amount of Bibimbap and Gochujang sauce (red chili pepper sauce) and then completed a preference test. Bibimbap was highly rated overall in the areas of appearance, color, smell, and taste. Gochujang sauce was also well-accepted in terms of taste and spiciness. Most of the participants disliked the seaweed and shiitake mushrooms, which means that Bibimbap can improve its garnish taste and aroma by removing them. Further, a more watery sauce was served as foreigners are not familiar with mixing food culture. Therefore, by offering diverse ingredient options, the acceptance of traditional Bibimbap can be increased in the U.S.

Recently, the Tenebrio molitor larva was recognized as a novel food ingredient by the Ministry of Food and Drug Safety in Korea. Accordingly, we investigated its physical and sensory characteristics to establish the cooking conditions that may increase the demand of T. molitor larvae as a food. In this study, T. molitor larvae were cooked by various methods such as hot air dry, oven-broil, roast, pan fry, deep fry, boil, steam, and by microwave. In the physical evaluation of texture, the hardness and fracturability values were highest when larvae were cooked in the microwave. The adhesiveness, springiness, and chewiness values were highest when larvae were boiled. Boiled and steamed larvae had the highest lightness (L value), while oven-broiled larvae had the highest redness (a value) and yellowness (b value) values. Sensory evaluations assessed the appearance, aroma, flavor, and texture of cooked T. molitor larvae. Steamed and boiled larvae sizes were significantly large and the form was well preserved similar to fresh larvae. The moisture heat cooked (steamed and boiled) T. molitor larvae had the aroma and flavor of steamed corn, canned pupa, and boiled mushroom. In case of oven-broiled T. molitor larvae, the aroma and flavor of mealworm oil, seafood, sweet and roasted sesame were higher than in those cooked by other methods. In texture among sensory evaluation, the hardness and crispiness were the highest in the hot air dried and oven-broiled larvae, whereas juiciness was significantly higher in the boiled and steamed. Accordingly, we suggest that oven-broiled T. molitor larva will be prefered by consumer, due to its the rich aroma and flavor.

This study investigated the spicy hot flavor related quality characteristics of cucumber salad prepared using spicy hot flavor graded gochujang that had been stored for 60 and 120 days. The results showed that the pH of both the 60-day and 120-day fermented gochujang was significantly higher in the cap-200 sample (p<0.001). In contrast to the results on pH, the acidity of both the 60-day and 120-day fermented gochujang was found significantly lower in the cap-200 sample (p<0.001). Measurements of salinity were found to be significantly lower in the sample with higher capsaicin content than in the sample with lower capsaicin content. The sugar content was found to be generally higher in the sample with the 120-day fermented gochujang than that with the 60-day fermented gochujang. Lightness (L) was higher in the sample with a lower capsaicin content than in the sample with a higher capsaicin content. The redness (a) was found to be significantly higher in the cap-200 sample than in other samples (p<0.001). The values of the L, a, and b tended to be lower in the sample with the 60-day fermented gochujang than in the sample with the 120-day fermented gochujang. The hardness of the cucumber salad was found to be lowest in the 120-day fermented sample with the cap-200 gochujang, which had the highest capsaicin content (p<0.05). The results of the sensory evaluation of the cucumber salads showed that the spiciness was stronger with the higher capsaicin content (p<0.001), and approximately one-level higher than the spiciness rating of hot pepper. The results of a key ingredient analysis showed that the sample with high capsaicin content was classified as having a relatively hot spicy aroma and flavor, and strong stinging pain, and the sample with the low capsaicin content was classified as having a salty aroma and a dark appearance.
