  • Tomato sauce is widely known as a health food, In this study perilla leaf was added to a tomato sauce and the resulting functional improvements were assessed. The moisture of the tomato sauce WITH 2% added perilla leaf was 89.52%, the highest observed likewise, sample pH also significantly increased with 2% perilla leaf, to the highest pH of 4.71, (p>0.001). Lightness L value of the control group was the highest at 40.70, and the redness a value and yellowness b value were highest in, the control group, at 15.77, and 17.70, respectively. The highest salinity was foung with 2% perilla leaf, 0.96, and the sugar content with 2% perilla leaf, was 9.57. The reducing sugar was highest in the control with 63.08. The change in the total bacterial counts was measured during 9 days of storage at $4^{\circ}C$, When perilla leaf was added to, the tomato sauce, no microorganisms were detected until 0~1 days of storage. After five days of storage, microorganisms were detected in the group with 2% perilla leaf. The control group ($1.8{\times}10^5$ CFU/ml) had the highest levels of microorganisms. As the amount of perilla leaf, the total viable count of microorganisms detected was less. In the acceptability test results, the color 6.9 of the 1.5% treatment group, received the highest evaluation. Flavor and taste of the 2% perilla leaf treatment group were highly appreciated at 6.1 and 6.6, respectively. The ranking of overall acceptability was 1.5%>1%>0.5%>10%>2% of perilla leaf; 2% perilla leaf was the most underrated. Based on these results, up to 1.5% perilla leaf could be added to tomato sauce and the commercial potential could be very high.

  • High amounts of lemon seeds are discarded as by-products of processing industries. It is important to find some measures, whereby they could be used in value-added ways. Although few studies have been conducted on lemon seed oils, no study has been conducted on the nutrient content of lemon seed sprouts. The objective of this study was to investigate the nutritional value and antioxidant potential of lemon seeds and sprouts. The 1,1-diphenly-2-picrylhydrazyl radical-scavenging potential, total polyphenol, and total free amino acid content were higher in the sprouts than in the seeds. Similarly, the content of such mineral elements as Fe, Na, and Zn, increased with germination. However, salicylic acid and total mineral content were lower in the sprouts than in the seeds. The results indicate that lemon seeds and sprouts could be regarded as high-value materials in food and cosmetic industries.

  • Sugars are a ubiquitous component of our food supply and are consumed as a naturally occurring component of many foods and as additions to foods during processing, preparation, or at the table. Most fruits and dairy products are high in sugars and thus naturally occurring sugars are consumed as part of a healthy diet. Some countries developed recommended daily intake figures(daily values : DVs or guideline daily amounts: GDA) for nutrients, and some countries, but not most have developed DV/GDA for total sugars. Dietary Reference Intakes for Koreans established by the Korean Nutrition Society in 2005, did not include the reference values for total sugar or added sugar. The committee on Dietary Reference Intakes for sugar was constituted in 2006 and discussed whether to special added sugars or total sugar. Although added sugars are not chemically or physiologically different from naturally occurring sugars, many foods and beverages that are major sources of added sugars have lower micronutrient densities compared with foods and beverages that are major sources of naturally occuring sugars. But it was so hard to calculate a dietary intake of added sugar for Korean people, because there was insufficient information about contents of added sugar during processing or preparation of Korean food. Currently Korean or US food labels contain information on total sugars per serving but do not distinguish between sugars naturally present in food and added sugars. Therefore the committee decided to set the reference value for total sugar for Koreans. According to the recommended diet pattern for Koreans suggested by the Korean Nutrition Society, estimated sugar intake from the sugar containing food based on 2,000 kilocalories is 67 g or 13% of total energy. Based on the data available on risk of obesity, hypertension, hyperlipidemia, insulin resistance, and metabolic syndrome from the analysis of Korean NHANES, it was insufficient evidence to set a UL for total sugar, but tended to increase serum LDL cholesterol and obesity at over 20-25% of energy from total sugar when consumed with high carbohydrates. Therefore the committee on Dietary Reference Intakes for sugar set the Acceptable Macronutrient Distribution Range for total sugar as 10-20% of total energy intake.

  • This study was preformed to make high quality fish cake made with silver pomfret, which is one of the savory, soft and delicious fishes by adding wasabi powder (WP). WP as natural additives was added to the ratio of 0.6%, 1.2%, 1.8%, 2.4%, 3%, a color values, texture, folding test, sensory evaluation, peroxide value, TBA value, and viable cell count were analyzed. L and a value were decreased significantly by the increase of the ratio of WP. However, b value was increased. In the folding test to show the flexibility of fish cake, it was measured AA in the all samples. As the result of measuring texture, hardness was increased significantly by the addition of WP, cohesiveness was the highest in 1.8 WP and 0.6 WP, Springiness showed no significant difference among samples. However gumminess and chewiness of fish cake adding wasabi powder were significantly higher comparing with control group. In sensory evaluation, 1.8 WP had the best score in overall acceptability. Fish cakes had lower peroxide value, TBA value and viable cell count after frying compared to the one without WP. These results indicate that fish cake could be prepared by adding the WP for high quality and functionality. Consequently, wasabi can be applied as a food preservative or additive in fish cake.

  • New type yogurt base were prepared from milk added with skim milk powder or purple sweet potato, and fermented by lactic acid bacteria (Streptococcus thermophilus and Bifidobacterium infantis, 1:1, v/v). The yogurt proudcts were evaluated for acid production(pH, titratiable acidity), number of viable cell, viscosity, sensory properties, and color value. The composition of some organic acids was also analyzed by GC. The acid production slightly decrerased by addition with purple sweet potato. There was no significant difference in viable cell counts between control (yogurt added with only skim milk powder) and yogurt added with purple sweet potato, and viable cell counts of all samples were above 9.08 log cfu/ml. Viscosity of yogurt added with purple sweet potato(36,800∼46,000 centipoise) was higher than that of yogurt added with only skim milk powder(32,200 centipoise). The overall sensory score of yogurt added with purple sweet potato(38.6%, dry base) was the best of tested yogurt. The major organic acid of yogurt added with purple sweet potato was lactic acid. its content was 0.997∼1.203%. malic acid, succinic acid, oxalic acid, and fumaric acid were analyzed out a little. Lightness and yellowness decreased by addition with purple sweet potato but redness increased. Total color difference($\Delta$E) with yogurt addition with purple sweet potato and only skim milk powder were very high(above 11.46).

  • Global competitive pressures are asking industrial companies to find the best way to meet their customer's requirements, reduce the costs of products, and increase productivity. Quality improvement has been proposed and implemented as a primary means of achieving these purposes. The quality improvement usually includes a goal of reducing the costs due to poor quality. While these costs of poor quality (COPQ) are not known precisely, they are known to be very high. Also, they may be underestimated by the hidden costs due to non-value activities, such as potential lost sales, costs of redesign due to quality reasons, and extra manufacturing costs due to defects, etc. In any manufacturing or service operation, all actions and resource expenditures of a company should be focused on creating value for customers. Any activity or resource of not creating the value for customers could be regarded as waste, which consequently causes the COPQ. Some companies did use dashboards to understand and identify value added or non-value added activities in order to reduce or eliminate wastes. These dashboards must be properly designed to consider inherent differences in manufacturing or service operations among business organizations. In addition, a structured quality improvement program such as the Six Sigma must support these dashboards. In this paper, a case study of designing dashboards for evaluating and reporting the COPQ in business units is presented.

  • Purpose: Bokbunja (Rub coreanus Miquel), mulberry and blueberry have been reported to have powerful anti-antioxidant and anti-aging activities. The purpose of this study was to compare the quality characteristics and antioxidant activities of gravy sauce added with Bokbunja, mulberry and blueberry. Methods: Quality characteristics pH, brix, color and sensory characteristics of samples were evaluated. Antioxidant activities of samples were compared using total phenol, 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) cation radical scavenging and 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activities. Results: Mulberry juice showed significantly (p<0.05) higher values of pH and $^{\circ}Bx$ compared to Bokbunja and blueberry juice. Bokbunja juice also had significantly (p<0.05) higher value of Color-L value than mulberry and blueberry juice. The total phenol contents and ABTS cation radical scavenging activity of Bokbunja juice were 236.50 mgGAE/100 g and 61.66%, respectively, which were significantly (p<0.05) higher than those of blueberry and mulberry juice. pH value of gravy sauce added with mulberry (MBS) was 4.67, which was significantly higher than that of the control gravy sauce (GS) and gravy sauce added with Bokbunja (BJS) which had the lowest (p<0.05) pH value 4.33. $^{\circ}Bx$ of GS (13.50) was not significantly different from that of MBS and BBS. However, BJS showed the lowest (p<0.05) value $12.33^{\circ}Bx$. Total phenol contents and ABTS cation radical scavenging activity of BJS were 78.09 mgGAE/100 g and 14.47%, respectively, which were significantly (p<0.05) higher than those of MBS or BBS. Values of sensory characteristics color, sour aroma and sour flavor of BJS were significantly (p<0.05) higher value than those of other samples. Conclusion: Bokbunja juice and gravy sauce showed higher antioxidant activities and higher acceptance test compared to blueberry and mulberry. Thus, Bokbunja has the potential to be added to as high value products in the food industry.
