  • Backsulgi were prepared with the addition of nutriprotein powder at 0%, 2%, 4%, 6%, 8%, and their sensory quality and mechanical characteristics were compared. In addition, the changes in the sensory and textural characteristics of Backsulgi were determined while storing them at the temperatures of 4$^{\circ}C$ and 20$^{\circ}C$ for 0, 1, 2, and 3 days. In the sensory evaluation, Backsulgi with 4% nutriprotein powder showed the highest score in overall quality. In the measurement of color changes, L value (lightness) was decreased, but a value (redness) and b value (yellowness) increased as the addition of nutriprotein powder increased. In textural characteristics, the hardness, gumminess and cohesiveness of Backsulgi were decreased by the increase of nutriprotein powder. The hardness and gumminess were increased as the storage time increased.

  • This study was carried out to investigate the quality characteristics of low-salt kimchi with salt partially replaced by Salicornia herbacea L. powder (SH). We prepared kimchi with seasonings in which salt was replaced by 0% (S00), 10% (S10), 20% (S20) and 30% (S30) SH. The salinity level of kimchi was about 1%, and there was no significant difference between the experimental groups. Although lactic acid bacterial numbers of kimchi replaced with SH (S10~S30) increased significantly compared to those of control (S00), the pH and titratable acidity of kimchi replaced with SH were not significantly different. Hardness of kimchi tended to increase as fermentation progressed and with SH addition. The results of the sensory evaluation corroborated the physicochemical characteristics. Furthermore, the sensory characteristics of kimchi were not significantly different upon addition of SH. The physicochemical and sensory characteristics of kimchi were not significantly different despite replacement of salt in kimchi seasoning by SH up to 10%.

  • The purpose of this study was to evaluate quality characteristics of the bread added with chlorella growth factor(CGF). The bread was manufactured by adding 0.5%, 1.0%, 1.5% or 2.0% of CGF(w/w) to wheat flour. The bread volume was increased from 1,755mL to 1,840mL as CGF contents increased from 0% to 1.0%. The lightness(L values)and the redness(a values) decreased with increasing CGF contents, but the yellowness(b values) increased with increasing CGF contents. Textural characteristics of the bread were influenced by adding the CGF. The breads containing CGF showed a decrease in hardness, springiness, gumminess and chewiness. In sensory evaluation, sensory scores decreased with increasing CGF contents for color. On the other hand, the highest sensory scores for grain, flavor, taste, softness, chewiness, aftertaste and overall acceptability were obtained, when CGF content was 1.0%. In conclusion, the bread with 1.0% CGF was the best quality in textural and sensory evaluation.

  • The sensory quality and the baking property of blonds containing 10-50% of rice flour with wheat flour were analysed by QDA. As sensory characteristics, color, air cell size, air cell distribution, flavor, softness, chewiness and overall quality were evaluated. Bread could be made successfully even using up to 50% rice flour. The color, flavor, softness and chewiness were increased in rice-wheat bread especially using 10∼30% of rice flour, but in case of using 40∼50% of rice flour those characteristics were not significantly different from those of wheat bread. The size of air cell in 10∼30% rice-wheat bread was not significantly different but in 40∼50% rice-wheat bread it was increased. The distribution of air cell was more even in 10∼30% rice-wheat bread than in wheat bread, but not in 40∼50% rice-wheat bread. The overall quality of rice-wheat bread was shown to be better in 10∼30% rice-wheat bread than in wheat bread.

  • Objective: This study evaluated the supplementary effect of higher concentrations of various disaccharides on processing yield, major physicochemical properties, and sensory attributes of Chinese-style pork jerky (CSPJ). Methods: CSPJ samples were prepared by marinating sliced ham (4 mm) with three dissaccharides, including sucrose, lactose, and maltose, at 0%, 15%, 18%, 21%, and 24%. Subsequently, the CSPJ samples were dried and roasted. The moisture content, water activity, crude protein, moisture-to-protein ratio, pH, processing yield, shear force, color, and sensory attributes of the CSPJ samples were evaluated. Results: The quality characteristics of CSPJ samples prepared with sucrose were more acceptable. By contrast, CSPJ samples prepared with lactose showed the lowest scores. However, the processing yield and moisture content were the highest for CSPJ samples prepared with lactose, which may be associated with improved benefits for cost reduction. Furthermore, sucrose and lactose supplementation resulted in contrasting quality characteristics; for example, CSPJ samples with sucrose and maltose supplementation had higher sensory scores for color than samples with lactose supplementation. Additionally, most quality characteristics of CSPJ samples with sucrose supplementation contrasted with those of the samples with lactose supplementation; for example, the samples with sucrose supplementation had higher scores for sensory attributes than those with lactose supplementation. Conclusion: Sucrose supplementation up to 21% to 24% was associated with the highest overall acceptability scores (5.19 to 5.80), enhanced quality characteristics, increased processing yield, and reduced production cost.

  • The purpose of this study was to investigate the quality characteristics of cookies containing Ligularia fischeri powder (0, 1, 2, 3, 4%) substituted for flour. This study measured the density, pH, spread ratio, volume, color values, hardness, and sensory properties of cookies. The pH of cookie dough significantly decreased in response to addition of Ligularia fischeri powder (LFP) at all levels. The spread factor of cookies also significantly increased with higher LFP content. In addition, Hunter's color L, a, and b values significantly decreased with increasing LFP content. According to hardness measurement, substitution of 1~4% LFP resulted in increased hardness compared to the control. In the sensory evaluation, sensory scores for color, flavor, and overall acceptability were highest in 2% Ligularia fischeri powder cookies. Thus, our results suggest that the optimum amount of Ligularia fischeri powder added to cookies was 2%. These results suggest that Ligularia fischeri powder can be applied to cookies to achieve high quality and functionality.

  • We manufactured the sausages replaced part (8%) of the pork fat (20.8%) with pepper seed powder (1%) and pepper seed oil (7%). The treatment of pepper seed did not affect pH and microbial quality, but decreased TBARS and VBN of sausages. Although the addition of pepper seed hardly changed textural properties of sausages except for increasing cohesiveness, it enhanced sensory characteristics such as taste, appearance, and overall acceptability. As expected, significant reductions were observed in the content of calorie, total fat, saturated fat, and sodium by replacing pork fat with pepper seed oil and pepper seed powder in sausages. Therefore, pepper seed is good enough to improve the sensory and nutritional quality of sausages.

  • In this study, we compared the quality and sensory characteristics of 4 types of fresh tomatoes and 2 types of canned tomatoes, and then determined the most preferred quality characteristics and tomato type for the production of tomato sauce. The sample tomatoes were prepared by cutting after either peeling or heating for 5 min. Soluble solids were in the following order: Italian canned >American canned, Cherry> Vita king > Aranka > general tomatoes. The primary free sugars were fructose and glucose, and we determined that fructose and glucose were the most prevalent sugars in the cherry and American canned tomatoes. The total sugars, which were the sum of the fructose and glucose contents, were consistent with the soluble solid contents. pH was measured in the following order: general> Italian canned> Cherry, Vitaking> Aranka> American canned tomatoes. The most abundant amino acid was glutamic acid, and its content in the unheated tomatoes occurred in the following order: American canned> Italian canned> Vita king> Cherry> general tomatoes; however, after heating, the Vita king tomato was followed by the American canned tomato. The lightness (L value) of the fresh tomatoes tended to be higher than that of the canned tomatoes, and it decreased after heating. The redness (a value) of the unheated tomatoes was in the following order: Italian canned> American canned> Vitaking tomatoes; after heating, the Vitaking evidenced the highest values, followed by the canned tomatoes. The result of our QDA profile of sensory characteristics according to redness, aroma, sweet taste, sour taste, palatability, and viscosity was in the following order: Italian canned > American canned > Vitaking tomatoes, which evidenced the most balanced hexagonal shape. In the preference test, 2 types of canned tomatoes and Vitaking tomatoes were the most preferred among the fresh tomatoes. From the correlation coefficients among the sensory characteristics, canned tomatoes were the most preferred for the production of tomato sauce due to its high redness, flavor, palatability, and viscosity values. Vitaking tomatoes were the most appropriate among the fresh tomatoes.
