  • The purpose of this research was to provide basic information for cookies made with black soybeans, chick peas, lentils, oatmeal, and brewer's yeast and to establish the optimum formula for the development of low glycemic index (GI) cookies with high biotin content for lactating women. This study was performed to determine the optimal composite recipe of oatmeal cookies with two different concentrations levels of bean powder (black soybeans, chick peas, lentils) and brewer's yeast using a central composite design. In addition, the mixing conditions of oatmeal cookies were optimized using response surface methodology of sensory evaluation and mechanical and physicochemical analysis. As a result, mechanical and physicochemical analyses showed significant values for lightness, redness, yellowness, hardness, and water content (P<0.05), while sensory evaluation showed significant values for flavor, taste, crispness, and overall acceptability (P<0.05). The optimal sensory combination was suggested to be 3.73 g of bean powder and 1.59 g of brewer's yeast. Considering all outcomes obtained throughout the experiments, brewer's yeast, black soybeans, chick peas, lentils, and oatmeal are suitable ingredients for increasing functionality and consumer acceptability of cookies. In addition, these results are expected to be useful in producing cookies of optimal quality, contributing to the development of various nutritious foods, and improving the food industry for lactating women.

  • Bombyx mori (silkworm pupae) is a unique and biologically significant insect, which is a recognized source of high quality protein that provides all the essential amino acids required for human health. Recently, many studies have focused on various biomedical applications of B. mori proteins. The purpose of this study was to manufacture protein-fortified kefir containing different concentrations of B. mori powder according to pH and sensory evaluations. The value of the protein-fortified kefir increased but the pH decreased with increasing incubation time, indicating that the amount of B. mori powder did not affect and pH. Addition of B. mori powder also did not affect the sensory properties of overall acceptability, texture, and color compared to control group without addition of B. mori powder. However, flavor and taste were affected by increasing the amounts of B. mori powder, with a significant difference in both flavor and taste between the control and treated groups (both p<0.05). There was no significant difference in overall acceptability, texture, and color. Further studies are needed for producing kefir as a dietary supplement utilizing the functional properties of B. mori.

  • The objective of this study was to investigate the effect of alcohol content in Makgeolli made with Chinese matrimony vine (M-CMV) on the sensory profile and consumer acceptability. The M-CMVs were prepared with 6, 7, 8, and 9% alcohol content. Descriptive analysis of M-CMV was performed with six trained panelists. Thirteen attributes were generated and their intensities were alcohol content dependent. The consumer acceptance test was conducted with 57 consumers. M-CMV samples with 7% alcohol had the highest acceptance rate (5.8) followed by 6% M-CMV (5.6). Commercial rice Makgeolli (CRM) had the lowest consumer acceptance. Consumers were divided into two groups by clustering analysis. The majority of consumers (n=38) preferred M-CMV and did not like the commercial sample. Only 19 consumers indicated high acceptance ratings for CRM. However, these consumers also preferred 6 and 7% M-CMV. Partial least-squares regression analysis revealed moderate attribute intensities were related to greater consumer acceptability. The optimal alcohol content for the greatest consumer acceptance predicted by linear regression was 6.7%.

  • This study investigated the quality and sensory properties of Tteokgalbi containing various amounts of roasted garlic powder by measuring the proximate composition, color, pH, cooking yield, electronic tongue, and sensory evaluation. Samples containing 3% and 5% roasted garlic powder had lower moisture content than the control group (p<0.05), however, protein content was higher (p<0.05). The redness of samples containing 3% and 5% roasted garlic powder was significantly higher compared to the control (p<0.05). pH decreased significantly with increasing amounts of roasted garlic powder (p<0.05). Cooking yield exhibited an upward trend with increasing levels of roasted garlic powder. The intensity scales of saltiness, sourness, and umami of samples containing roasted garlic powder were stronger than those of the control. Samples containing 3% roasted garlic powder scored the highest flavor and overall acceptability. These results indicate that adding 3% roasted garlic powder can enhance the quality and sensory properties of pork Tteokgalbi.

  • This study investigated the standard recipe and changes in the quality characteristics of Chungkukjang-Kimchi (CKK) and evaluated its acceptance by elementary school students. The acceptability of Kimchi among elementary school students was evaluated by monitoring the plate waste rate. Chungkukjang powder was added to the Kimchi recipe at 0, 20, 40, 60% of the total weight of red pepper powder. The pH of the CKK decreased as fermentation proceeded, and the total acidity was $0.24{\sim}0.25%$ in all samples. The salinity of the CKK was 2.32%. The L color value was significantly lower in the treatment groups than in the control group. The b and a color values increased in the beginning, but tended to decrease during fermentation. In the sensory evaluation, there was no significant difference in appearance on preparation day, but there were significant differences on the 6th (p<0.05) and 20th days (p<0.01), with the highest scores observed in the 40% added group. Sourness increased significantly (p<0.001) during fermentation in all samples. There were significant differences (p<0.001) in crispness on the 3rd day among the treatment groups, and it tended to decrease as fermentation progressed. There were significant differences in flavor during the early stage (p<0.001), but there were no differences as fermentation proceeded. Overall acceptability was high in the 40% added group. Evaluation of acceptability by monitoring the plate waste rate in the school dining room showed that acceptability was highest in the 20% added group. Thus, it was concluded that acceptability among elementary school students was highest for CKK from the 20% Chungkukjang group.

  • Response surface methodology was used to study the effect of egg albumen (5-15 g), vegetable oil (5-15 g), and corn bran (5-15 g) on sensory and textural (firmness and toughness) quality of chicken nuggets cooked by the oven, steam, and microwave methods. The egg albumen and vegetable oil had a positive linear effect but corn bran had a negative linear effect at p<0.01 on sensory overall acceptability scores of nuggets. Firmness and toughness scores were increased significantly (p<0.01) with the increase in corn bran level in the formulation. The optimum level of egg albumen, vegetable oil, and corn bran were obtained and validated. Cooking methods also affected the sensory and textural quality of nuggets. Steam cooked nuggets had higher values of sensory scores than oven and microwave cooked nuggets. Oven cooked nuggets showed higher values of firmness and toughness than steam and microwave cooked nuggets. Results of this study suggest that emulsion based meat products can be enriched with dietary fiber source like corn bran without compromising the sensory and textural quality of the products.

  • This study was conducted to analyze sensory characteristics and consumer acceptance with cookies made using various levels(0, 2, 4, 6 and 8% w/w) of Chrysanthemum indicum L. powder. Ten panels assessed sensory characteristics using a 15-point hedonic scale and forty-five consumers evaluated their acceptance based on a 7-point hedonic scale and best-worst scaling. The descriptive analyses reveled that cookie flavor did not differ significantly between the 2% added sample and the control. Cookie color and after taste increased significantly, while hardness, roasted taste, and sweetness taste decreased significantly according to increasing Chrysanthemum indicum L. powder concentration. In addition, the results of consumer acceptance showed that the overall acceptability, appearance, color, flavor, and taste decreased significantly in response to increasing Chrysanthemum indicum L. powder concentration. However, color, flavor, taste and overall acceptance with cookies did not differ significantly differ between the 2% and 4% sample. Additionally, among the cookies made with Chrysanthemum indicum L. powder, the 2% sample received the highest scores. In conclusion, the sensory optimal ratio of Chrysanthemum indicum L. powder was 2% based on the descriptive analysis of sensory characteristics and the consumer-acceptance testing.
