  • This study was carried out to investigate the effects of various kinds of commercial salts, including sun-dried (Korea), purified, and traditional salts on the chemical and sensory properties and growth of microorganisms involved in kimchi fermentation. Kimchi was prepared by salting in 10% NaCl solution for 2 hours followed by addition of other spices and fermentation at $20^{\circ}C$. The decreases in pH suggested that kimchi fermentation can be classified into 3 steps: initial, intermediate, and final stages. In texture analysis, the hardness and fracturability of traditional salt kimchi were higher than those of regular kimchi. From the sensory evaluation test for kimchi, sensory scores were high for traditional salt addition, especially taste, overall preference and texture. Among various microorganisms related to kimchi fermentation, the growth of Leuconostoc mesenteroides, Lactobacillus plantarum, Pichia membranaefaciens and Escherichia coli were examined. Based on the conditions of kimchi fermentation, a 2% and 5% concentration of each salt were studied. Also, the conditions of the cultures at $37^{\circ}C$ were examined. There was no considerable difference in the growth of Leuconostoc mesenteroides, Lactobacillus plantarum, Escherichia coli in the different kinds of salts. However, the growth of Pichia membranaefaciens was strongly inhibited by a 5% concentration of traditional salt during incubation at $37^{\circ}C$.

  • This study was conducted to investigate the effects of saltwort, on the quality characteristics of sponge cake. In addition, we examined the commercialization potential of sponge cake containing saltwort. To accomplish this, saltwort was added to sponge cakes at concentrations of 0%, 3%, 5% and 7% and quality and sensory tests were then conducted. The 7% group had the highest water and ash content. There was no difference in the fat content between samples. The control group showed the highest protein content and the lowest specific gravity. As the content of saltwort increased, the specific gravity of the sponge cake increased. Additionally, the dough yield and loss during baking were highest, in the control group, and these values decreased as the saltwort content increased. Similarly, the volume and specific volume were highest in the control group, and these values decreased as the content of saltwort powder increased. Color measurements of the samples, revealed that the L-value decreased as the content of saltwort powder increased. Furthermore, the a-value of the saltwort powder groups was higher than that of the control group and the b-value was highest in the 7% group. There were no differences in elasticity and cohesion between samples, but chewiness and brittleness increased the content of saltwort powder increased. The results of the sensory test revealed that the color, flavor and taste scores were the highest in the 5% group. The pore size was greatest in the control group, while hardness was greatest in the 7% group, chewiness was highest in the 5% group and moistness was highest in the 5% group. Finally, the overall preference was for the 5% group.

  • The object of this study was to investigate the effects of rice particle size on the physicochemical properties of beef-rice porridge. The pH of beef-rice porridge was decreased as compared to that of the control, while the redness of beef porridge increased according to rice particle size. The viscosity of flour in the beef-rice porridge was the highest among three porridges, at $40^{\circ}C$. The protein content of beef-rice porridge was increased 3-fold over that of rice porridges. The total amino acid content of the beef-rice porridge was 3071.2 mg/100 g, and that of rice porridge was 1147.5 mg/100 g. As compared to rice porridge, the maximum amounts of the amino acids Lys and Thr were increased beef-rice porridge. Sensory evaluation results showed that the beef-rice porridge with a particle size half that of rice had the highest scores in color, taste, texture, and overall preference. Based on these results, it is suggested that beef-rice porridge with a particle size half (0.7-2.5 mm) that of rice has optimal quality in terms of both physicochemical and sensory properties.

  • The metacognitive experience of the ease or difficulty with which new, external information can be processed, referred to as 'processing fluency,' has been shown to influence a wide range of human judgments including truth judgments, familiarity judgments, risk perception, evaluation, and preference (see Alter and Oppenheimer 2009 for a review). The current research explores the possibility of a consumer's product innovativeness judgment based on the difficulty of processing new information. In specific, this study examines if the inferential link between (dis)fluency-(un)familiarity can feed into the perception of innovativeness. This study also explores how a consumer's processing motivation can moderate the consumer's reliance on processing fluency in judgments and how the influence of fluency can vary depending on judgment task orders. In an experiment, participants rated a new product's innovativeness and then indicated their product attitude (or vice versa depending on the judgment task order condition) after reading a product review article that was printed in either an easy-to-read or a difficult-to-read font (for fluency manipulation). The findings show that low need for cognition individuals infer higher product innovativeness when processing product information is difficult rather than easy, consistent with the common assumption that 'new information is more difficult to process than familiar information.' The findings also suggest that once low fluency is attributed to innovativeness, it may no longer lead to a negative response to the product. High need for cognition individuals' judgments on product innovativeness are not affected by fluency. The findings also demonstrate a judgment task order effect on the use of fluency in judgments (e.g., Xu and Schwarz 2005). This study provides the first evidence that an individual's fluency experience can be used as a source of information in product innovativeness judgments especially under low processing motivation conditions. The findings can help marketers better understand the malleability of consumer judgments and perceptions of product characteristics (e.g., product innovativeness) by demonstrating an interesting interplay of processing fluency, processing motivation, and judgment task-related contextual factors.

  • To produce super sweet corn sikhye, substituted for sweetener, the ratio of rice and super sweet corn was adjusted and processed with complex enzymes during saccharification, and their physicochemical and sensory properties were analyzed. The soluble solid content of the control and Corn-5 showed significantly high content at 13.50 °Brix, and the reducing sugar content of Corn-5 showed the highest content at 9.45%. The control showed the lowest free sugar content among all the experimental groups, excluding maltose content. In the enzyme-treated corn sikhye group, as the amount of super sweet corn increased, the content of sucrose decreased and the contents of glucose and fructose increased. The content of ascorbic acid and polyphenol compounds increased as the amount of super sweet corn increased. DPPH and ABTS radical scavenging abilities increased with increasing ratio of super sweet corn and enzyme treatment compared to the control. In the case of sensory evaluation, Corn-3, which substituted 30% of super sweet corn for rice and treated with enzymes, showed higher evaluations in taste, sweetness, and overall preference than those of the control.

  • The oriental melon poses challenges in terms of long-term storage and distribution. Addressing these issues requires an extension of the storage life through appropriate processing. In this study, pretreated hot-air dried oriental melon slices (steamed and freeze-thawed) were prepared, and their physicochemical and organoleptic properties were examined. The control group (CON) consisted of hot-air dried oriental melon slices without pretreatment, while the steamed group (STG) and freeze-thawed group (FTG) consisted of hot-air dried oriental melon slices pretreated using steaming and freeze-thawing methods, respectively. The moisture contents detected in the CON, STG, and FTG groups ranged from 15.96% to 27.30%, with variations of 7.53 to 8.40 °Brix for the soluble solid contents. The CON group showed the highest Hunter color value for lightness (L*) and the lowest value for redness (a*). The texture profile analysis revealed the highest hardness and chewiness in the order of STG > CON > FTG. Considerable differences were observed in springiness and adhesiveness in the FTG group compared to the other groups. The organoleptic evaluation showed that the CON group had the highest sensory scores for overall preference. These findings indicate that the properties of hot-air dried oriental melon slices were influenced by physical pretreatments and that manufacturing these slices without pretreatment is the most effective method in terms of processing simplicity and cost efficiency.
