Bifidobacteria are probiotic organisms that provide both flavor and health benefits when incorporated as live cultures into commercial dairy products. Because bifidobacteria are very sensitive to environmental conditions (acids, temperature, oxygen, bile salts, the presence of other cultures, etc.), their viability in human gastrointestinal tract is limited. The microencapsulation of bifidobacteria is a process to protect them against harsh environmental conditions, thereby increasing their viability while passing through human gastrointestinal tract. To confirm the survival rate of microencapsulated Bifidobacterium breve CBG-C2 in milk, their survival rate was compared with several kinds of free bifidobacteria and lactic acid bacteria in commercial yogurt products under simulated gastric and small intestinal conditions. Double-microencapsulation of the bacteria was employed to increase the survival rate during digestion. The outer layer was covered with starch and gelatin to endure gastric conditions, and the inner layer was composed of a hard oil for the upper small intestinal regions. Almost all microencapsulted bifidobacteria in the milk survived longer than the free bifidobacteria and lactic acid bacteria in the commericial yogurt products under the simulated gastric conditions. Numbers of surviving free bifidobacteria and lactic acid bacteria in the commercial products were significantly reduced, however, the viability of the microencapsulated bificobacteria in the milk remained quite stable under gastric and small intestine conditions over 3$\sim$6 hrs. Thus double-microencapsualtion of bifidobacteria in milk is a promising method for improving the survival of bifidobacteria during the digestive process.

This study was investigated the contents of total polyphenol, flavonoids and antioxidant and antimicrobial activities of Codonopsis lanceolata extracts according to different steaming times. The contents of total polyphenol and flavonoid proportionally increased from 6.45 mgGAE/g to 18.26 mgGAE/g and 2.01 mgRE/g to 6.12 mgRE/g according to ethanol extracts at EDS7. DPPH radical scavenging activity was found to have been 15.26~65.2% and showed the highest level of antioxidant activity at EDS7 was 65.2%. The activity of ABTS radical scavenging and SOD-like activity were also the same result. DPPH and ABTS radical scavenging activity was related to the number of steaming, and the scavenging activity was increased up to 7 times of steaming. The antimicrobial activity of EDS7 had strong antioxidant activity. Antimicrobial activities were examined against 5 microorganisms related to pathogens and food poisoning. The antimicrobial Activity was different depending on the bacteria, but it was effective at the concentration of 300 mg/mL rather than 150 mg/mL. These results showed that Codonopsis lanceolata extracts with a different number of steaming would be conducted to confirm the possibility of developing antimicrobial and antioxidant. It will be helpful in the study of component analysis of Codonopsis lanceolata extracts processed products.

The purpose of this study was to derive practical improvement measures for the food traceability system that could improve food reliability and secure food safety. To this, in our survey May-June, 2019, 567 adult males and females were analyzed for recognition and experience of the food traceability system, measures to improve the system, and intention to make additional payments to improve the system. In the case of a food safety accident, 2.54 of 5 points were given on if the food was recalled or not. Approximately 77.4 percent of the respondents had never seen indication of a food traceability system, and approximately 93.8 percent had no access to, or experience with, using the system. Most respondents said that the food traceability system should be applied to items that need to be applied. As the volume of data that is recorded and managed by the government is recognized as high, improvement is needed. Finally, it was analyzed that the company intends to pay an additional 1.34% on average to expand its food traceability system. A more sophisticated cost analysis is needed to apply the improvements proposed to complement the plans that are acceptable to consumers and the industry.

This study was to investigate dining behaviours of 420 businessmen living in urban regions (Taegu, Gumi, Young-Chon and Chang-Won) in Kyungbuk and Kyungnam. This survey was carried out by questionnaires. The results were summarized as follows; Among all respondents, dining out once a day was most frequent. Education (p<.05), age (p<.001) and marital status (p<.001) were significant. Socialization was the most frequent reason for dining out. In the choice of food, Korean food was the most frequent (68.1%). Taste (41.4%) was the most frequently cited reason for food selection followed by variety of food (18.8%) and price (8.8%). The respondents favorite foods were: Korean food; Doen Jug Soup (31.9%); Western food; Pork Cutlet (47.6%); Chinese food; Gan Ja Jang (31.2%); Flour-bared food; Kal Gook Su (55.4%), and Fast food; Ramen (26.4%). The most frequent choices of where to eat were the company cafeteria for lunch and Korean restaurant for dinner (p<.001). Responses to inquires concerning sanitation, facilities and service were mostly "normal". They wanted lower price (30.5%), a more variable menu (24.8%), and more vegetables and fruits (18.1%) in restaurant and cafeteria food. Age (p<.05) and marital status (p＜.001) were statistically significant.

After the industrial revolution, we have changed whole life-styles. This trend has brought a change in our eating style. Nowadays, the great number of people go out to eat-even three meals a day. As a result, the growth rate of food service industry increases day by day. Some restaurants are managed by the large scale company and others by the small scale ownership. Though developed countries are in the maturity step of the product life cycle in this field, we are in the growth step. We will hold the in 2002. A lot of tourists and the press will rush to Korea. They must have their meals at the restuarant. Therefore, we need more practice to satisfy them and to lead to successful management in this field. Also, we need an evaluation to qualify each business so that our food service industry does not decline compared to other country's. This study is trying to find how to evaluate and qualify each business in the various areas: service, the quality of food, the mood of the restaurant and so on. In addition, it includes the restaurant rating form.

There were the operation of food management, the operation of menu, the operation of equipment and facilities management, the operation of solid waste and safety management, the operation of waiting time management. As a result of the survey B&I foodservice was listed higher than University foodservice as food hygiene, FIFO and food shelf life. University foodservice employees worked 4 hour longer than B&I foodservice employees, so turnover rate was higher than it. Comparing the number of feeding, B&I foodservice equipment and facilities scale was bigger than University foodservice equipment and facilities. The rate of solid waste on B&I foodservice was 11.468% and the rate of University foodservice was 16.23%, the waiting time of University foodservice was about 8mins longer than B&I foodservice.
