  • In this study Muffins adding each 0, 1, 3, 5 7% of Acai Berry powder, which has very high anti-oxidant constituent, have been made, and its quality characteristics have been surveyed. From the volume and specific volume measurement, it has been decreased for MA1, 1% of Acai Berry powder added muffin, but the tendency thereafter has shown increasing (p<0.001). From texture characteristics gumminess and chewiness of MA0, reference group, was the highest by 885.86 g/ cm and 6645.71 g, and has shown decreasing tendency as per the adding rate of Acai Berry powder increased (0.001). The electronics scavenging activity of MA7, 7% added muffin, was the highest by 68.91%, and the ascending order was MA1 < Reference Group < MA3 < MA5 < MA7. From the preference test of Acai Berry powder added muffin, MA3, 3% added muffin, was the most preferable one from color, taste as well as total preference. As the added volume of Acai Berry powder is 5% or more, the typical taste and flavor of Acai Berry gives influence to the taste and flavor of muffin, so the preference level has been decreased. Thus the added volume of Acai Berry powder 5% or more is not recommendable.

  • The cooking characteristics of Hicook with lecithin and GMS as emulsifier were examined for effect on the reduction of oil levels in fried foods. Hicook and soybean oil were used in stir-frying and pan-frying, and in case of Hicook the weight of oil absorbed and spattered during cooking were significantly lower than in case of soybean oil. Next this study attempt to standardize the recipe for preparation of selected Korean foods, especially in regards of the amount of oil used during cooking. The foods studied were all used frequently in Korea, they inculded stir-fried vegetables, stir-fried rice, and pan-fried fish and soybean curd. The results showed that Hicook, even in a half amount, made it possible cooking food with good properties, and calorie content of cooked foods could be lowered considerably. The trained panelists evaluated sensory characteristics of foods, flavor, appearance, and overall acceptability. Sensory qualities of food prepared with Hicook were highly acceptable, and rated better than controls in flavor and overall acceptability. But because stir-fried food was accepted greasy and oily in customarily, the appearance was rated lower than comtrol. In summary, application of hicook offers means of lowering fat levels while keeping sensory quality good. The emulsifier in Hicook is responsible for reduction of oil content and improvement of quality of fried foods.

  • The effect of commercial Doenjangs (Korean soybean pastes) on sponge cake making was studied. When Doenjang was added to e99 foams at levels of 5, 10, 15 and 20%, there were no big differences in viscosity or stability of egg foams up to 15%, and thus in cake volume index, compared to those of control (without Doenjang). In the results of preference rank test, cake with 10% Doenjang was preferred to the other cakes. Therefore, it was decided that the addition of 10% Doenjang was suitable for sponge cake making. When seven commercial Doenjang products were used at 10%, there were differences in physical and sensory properties. The decreased viscosity of egg foams reduced their stability and so decreased the quality of the sponge cakes with low volume index and low texture scores. The use of Doenjangs improved the flavor of sponge cake and so countervailed the undesirable egg flavor. Especially, “C” Doenjang product, which increased the viscosity and stability of egg foams, produced good foaming ability and the highest physical and sensory quality, thus the higher overall acceptable scores than the control. It was probably due to its high amount of protein hydrolysate above 10-KDa. Consequently, the suitable amount of Doenjang was fixed at 10% and “C” Doenjang product was chosen as the best among the commercial products for sponge cake making.

  • For the standardization and quality improvement of traditional Korean Nuruk, 120 strains of fungi were isolated from Nuruks and 18 strains of them were selected as strains analysing the amylase and flavor. The genera of these fungi were identified as Aspergillus sp. (14 strains), Penicillium sp. (3 strains) and Rhizopus sp. (1 strains) by the conventional slide culture. Most of these fungi showed a better productivity of the saccharogenic and dextrinogenic enzymes in raw wheat bran culture than in cooked wheat bran culture. The ability of acid and flavor production was good in the raw wheat bran culture, and aflatoxins were not produced under the same culture. Penicillium sp. and Rhizopus sp. had high cell growth and amylast activity. Mixed culture of Aspergillus sp. No.3-6 and Penicillium sp. No.7-7 revealed a high liquefying and saccharifying activity as well as high flavors production. These results indicated that these fungi was proper strains for making Nuruk of good quality.

  • In this study, we examined the changes in loaf weight, loaf volume and specific volume, moisture content and water absorption, pH and titrable acidity, shape, texture profile and sensory evaluation using sour dough instead of dough conditioner in bread making. The weight and volume of bread tended to increase in the sour dough bread, compared to the control. The pH of bread tended to be lower in the sour dough bread. The control bread had large irregular pores that were fewer in number, while the sour dough bread had small spots and was very dense and even throughout the whole surface. The texture profile of bread such as hardness, cohesiveness, chewiness and brittleness was lower in the sour dough bread. There were no significant differences in the sensory characteristics of the breads, except for the shape of bread. However, the sour dough A bread was better in color, texture, flavor, touch, moistness, taste and overall acceptability, and the sour dough B bread was better in flavor, touch and taste than the control.

  • Quality characteristics of kochujang prepared with strawberry puree (10, 20, and 30% on a total weight basis) were investigated at 30 and 300 days of fermentation. The highest $L^*$-value was found in 30% strawberry kochujang at 300 days of fermentation. In contrast, the highest degree of redness ($a^*$) was observed in 30% strawberry kochujang at the early stage of fermentation. During the fermentation, values of $L^*$, $a^*$, and $b^*$ increased except $a^*$-value of 30% strawberry kochujang, indicating proper substitution of strawberry puree could preserve the desired color of kochujang. After 300 days of fermentation, hardness, gumminess, and chewiness increased while adhesiveness decreased significantly (p<0.05). Taste score and Pearson coefficient between sensory and strawberry concentration revealed that 10% strawberry kochujang was more acceptable than the others, due to color and the formation of flavor compounds during the fermentation and these compounds enhanced the flavor of kochujang.

  • The red ginseng powder was added to Yackwa dough as ratio to 0%, 2%, 4%, 6% and 8%, respectively to know effect of red ginseng powder on Yackwa quality and preservation. The expansion, color, texture and preference characters were investigated at 0,2 and 4 weeks, respectively. The peroxide and acid value were also measured. The 4% addition increased greatly expansion rate. In color test, L value lowed at addition of red ginseng powder and at long storage period. the b value lowed as the addition was increased, but a value was not affected by the addition of red ginseng powder. In mechanical texture test, addition of red ginseng powder had a tendency to show low cohessivness, springness, gumminess while hardness increased. The springness, brittleness and cohessivness decreased while hardness increased at long storage period. In sensory test, surface color, bitterness and red ginseng flavor were recognized strong by addition of red ginseng powder but oily taste, crispness, softness and overall preference were weak. The surface color and red ginseng flavor were strong at long storage period but sweetness, softness and overall preference decreased, respectively. The peroxide value increased at long storage period and decreased after 6 week. The 2% and 4% addition showed lower peroxide value compared to other treatment. The acid value increased at early storage period, but did not change after 4 weeks.

  • Objectives : Based on the entries on each medicinal's 'specification' and the phrase '所以然' in the Shennong Bencao Baizhonglu, this paper aims to examine Xu Dachun's understanding of herbal medicinals. Methods : One hundred medicinals from the text were sorted into eight categories: Qi, flavor, color, form, quality, nature and characteristic, time of growth, and producer, then examined. Results : 1. Medicinals related to Qi were aromatic and pungent and warm. 2. Medicinals related to flavor were explained according to the Five Flavors' nature in terms of the thing and its functions theory. 3. Medicinals related to color were explained in relation to the Five Colors, whose interpretations were rather erratic. 4. Medicinals related to form were explained as it being possible to figure out their effects based on each medicinal's shape and form. 5. Medicinals related to quality were those that were used to manage dryness and dampness using their dry or wet qualities. 6. Medicinals related to nature and characteristics needed to be understood in their originality to grasp their unique abilities. 7. Both producer and time of growth were closely related to each medicinal's efficacy. Conclusions : Understanding of the application of medicinals in the Shennong Bencaojing through continuous examination into each medicinal's 'specification' and 'its reasoning', together with their clinical application, will allow for learners to build an understanding of herbal medicinals.

  • A survey on the quality improvement and preference for green onion kimchi by Chinese and Japanese consumers was conducted by 30 Korean specialists in order to develop an improved green onion kimchi product. The long green onion shape, kimchi juice, seasonings, off-odor of fermented sea food, and stimulatory flavor of green onion were the main issues considered for the improvement of green onion product. Usage of the favorite ingredients of the Chinese and Japanese consumers was also suggested. The percentages of Chinese and Japanese who already knew green onion kimchi were 54.1% and 30.3%, respectively, whereas 46.8% of Chinese and 28.1% of Japanese have actually tried green onion kimchi in Korea. There was no significant difference in the preference for green onion kimchi between Chinese (3.25/5.0) and Japanese (3.17/5.0) consumers. For recommendations for improving the quality of green onion, Chinese consumers thought off-flavor, fibrous texture, and fermentation level were more significant while the Japanese considered red color, various taste, MSG content, and length of green onion. Seasoned tofu with green onion and rice were suggested as complementary foods to green onion kimchi by the Chinese and Japanese, respectively.
