Kmich is the traditional vegetable fermented food. Like other traditional foods. it was not known when the kimchi was first processed. In the chinese historical litera tures, Salt and varlous vegetables were used in Korea from the time of kokuryo and shila Dynasty. Brined vegetable product might be therefore, processed at that time for the winter. But the product was highly salted and any seasonings were not added at all. Chinese cabbage and ned pepper were used for kimchi processing in 15-16 centureis. Vanious type of Kimchi simllar to present products were processed thereafter.

This paper considers a single facility scheduling problem for the fabrication of components supporting the subsequent assembly into products. Each product consists of two types of components, one is common to all products and the other is unique to itself. The unique components are processed individually and the common components are processed in batches, and a distinct setup is incurred for the production of a batch of common components. Under the so-called “batch availability” environment, we propose an efficient dynamic programming(DP) procedure for the optimal sequencing and batching schedule with minimum total completion times of products in the situation that each product is said to be complete if both common and unique components of the product are finished. Computational results show that the proposed DB procedure is more efficient than the previous work which has considered the same problem as this paper.

A geographical indication is a protected trade name or mark for a product that corresponds to a specific geographic location or origin. Geographical indications have been widely used in European countries over the last three decades, mainly for wine and food products. This study investigates the consumer perception of geographical indications for agricultural and processed products and purchase experiences of consumers. It also examines consumer intention to pay more for geographical indication products. The findings from the empirical investigation showed that only 24.0% of the respondents have purchased geographical indication products whereas 49.5% of the respondents have not. Meanwhile, 26.5% of the respondents reported that they were unaware of geographical indications. Main reasons of purchasing geographical indication products were trust in quality, safety, and better taste. On the other hand, main reasons of not purchasing geographical indication products were lack of knowledge and no distinctive quality. The respondents answered that they would pay more for geographical indication products especially for luxury items such as ginseng, wine, and beef.

This study was targeted on the non-processed, semi-processed, and full-processed seafood to investigate the consumers' importance and satisfaction levels of purchase attributes for each seafood product. The present study conducted a survey on 335 randomly chosen seafood consumers. Respondents' importance-satisfaction scores of purchase attributes were measured. The results were as follows. The importance of purchase attributes was significantly higher than the satisfaction on 21 out of 23 attributes, according to the non-processed, semi-processed, and full-processed seafood(p<0.05). Consumers regarded intrinsic attributes such as 'freshness' of products as very important when purchasing non-processed seafood, and their satisfaction was also high. On the other hand, for semi-processed and full-processed seafood, external attributes such as 'date of manufacture or expiration date' were considered as more important attributes to purchase them. Consumers also perceived that full-processed seafood was less in quantity and more expensive than non-processed and semi-processed ones. In case of semi-processed seafood, the difference of importance-satisfaction score for 'taste' was large, and it was considered the taste should be improved according to consumers' taste.

This study was aimed at comparing the dietary patterns of university female students according to their residence type. As for subjects, one hundred and twenty students of Kongju national university were chosen as a total. They were devided into three groups ; those who live in family home, or university dormitory, or self-boarding house. In this study, intakes of food and nutrient and dietary behaviors of each group were investigated through two-day food records and questionnaire. The result was that mean daily intakes of calcium and iron were lower than RDAs in all groups. According to residence type, subjects of family home and self-boarding seemed to have more serious problem in the nutrients mentioned above considering the proportions of less than 2/3 of RDAs. Especially, iron status was poorer than any other nutrients in the aspects of this proportion and food source. Iron was taken largely from vegetable foods which were recognized as a source of low bioavailability of iron. The average distribution ratios of breakfast, lunch, dinner and snack to total calorie intake was 22, 29, 30 and 19. Thus, it proved that breakfast tended to be more negligent than any other meals, and that snack was an important means to give nutrients for subjects. This meal pattern might be one of the factor for the decrease of the dietary quality. Processed foods were founded to be an important source for providing nutrients. Percentages of calorie, carbohydrate and fat consumed by processed foods to total nutrients. Percentages of calorie, carbohydrate and fat consumed by processed foods to total nutrients intake were 30.6, 29.5 and 46.2. However, other nutrient intakes from processed foods such as vitamin and mineral were small. And processed foods which give nutrients were mainly cereal products like ra myon, bread, and milk and milk products. Consequently, processed foods seemed to be selected as a combinient substitute food which supply calorie to fill their hunger. According to the living type, dormitory students had them more frequently than any other groups. Food habit score was within the category of poor or fair. Particularly, the score of self-boarding students was the lowest of groups(p<0.05). The major dietary problems were small or overating, missing meal and irregular eating. The degree of these problems was a little different among groups(P<0.01). Nineteen kinds of food were consumed per day, and family home and self-boarding students had foods less variously than dormitory students(P<0.05). Proportions of skipping breakfast, lunch and dinner were 20.8, 12.5 and 8.3%. Accordingly, breakfast was missed more often than any other meals. And self-boarding students missed breakfast more often than any other groups. As a conclusion, subjects should take more calcium and iron, and eat diverse foods to improve their nutritional status. And it is also necessary that breakfast should be regarded more importantly, and that processed foods should be taken considering nutritional balance. In view of residence type, subjects of family home or self-boarding had more dietary problems than dormitory subjects. Thus, these results suggest that university female students might have low ability of meal management, and dietary patterns were different by their residence type. Therefore, nutrition education for them should be carried out with respect to dewelling environment.

According to changes in population, economic conditions, life-stile and eating habits, the frui ts and vegetables market wi 11 be shi fted from processed (i. e. , canned) to fresh. Undressed fresh produce, consisting of washed, disinfected and peeled fruits and vegetables that either sliced or grated, are currently increased in demand by retail and institutional market which use them as salad components or in ready-to use foods, Main attributes of minimally processed fruits and vegetables are convenience and fresh-like quality. Minimally processed Products readily deteriorate in quality, especially color and texture, as a result of endogeneous enzyme enhanced respiration and microorganisms which lead to reduced shelf Iife.

Minimally processed Products readily deteriorate in quality, especially color and texture, as a result of endogeneous enzyme enhanced respiration and microorganisms which lead to reduced shelf Iife. Thus. to prevent these undesirable changes , val'ious techniques such as controlled atmosphere (CA) storage, modified atmosphere OIA) storage, including vacuum packaging have been receiving considerable attention, Although milch research has been done to find optimal conditions for whole intact frui ts and vegetables, only limi ted information is avai lable on fresh cut. and other minimally processed products. 81 iced frui ts exhibi t increas~d ethylene production and respiration compal'ed to whole f, 'uits during distribution in response to tissue damage. As a result, accelerated senescence and enzymatic browning OCCUI', Recent l'esearch on minimally processed fl'uits and vegetables has mainly focused on methods to inhibit browning, due to ban on use of sulfur dioxide, In order to retard or prevent these physiological changes, val'ious al ternatives, reducing agents. acidulants, chelating agents and inol'ganic sal ts have been evaluated for use on fresh cut fl'ui ts. Al though some agents were effective replacement for sulfur dioxide. consum$\textregistered$I'S demandless use of chemical on such products. Shel~ life of minimally processed products has been extended by inhibition of metabolic reactions associated with loss of quality and by inhibition of aerobic spoilage caused by wide variety of microorganisms. Appl ication of ~I.-\ packaging, including vacuum packaging, retards the rate of respiration, prevents growth of aerobic spoilage organisms, inhibits oxidation and color deterioration. Tissue softening is another major problem in minimally processed products because enzymes re 1 a ted to ce 11 wa 11 degrada t i on are not inactivated. Various treatments have been investigated for retardation of the softening of sliced products. Some studies have concentrated on the application of an active packaging system with ~I, l. packaging and calcium infi 1 tration as possible measures to retain firmness of processed products. In my opinion, one important step for production of minimally processed frui ts wi th favorabl e color of cut surface and firm texture is the selection of better cultivar. As the view, changing tendency of fresh color by apple cultivars and relationship between the tendency and PPO activity will be discussed in the seminar. In addition to the topic, research result on quality enhancement of fresh apple slices by heat shock treatment will be introduced.

Egg production in Korea was 393 thousand M/T in 1990. More than 10 thousand M/T egg was imported and the amount imported has increased every year. Despite consumption tendency of increasing processed food, creation of additional demand is not likely because domestic egg consumption mainly depends upon table eggs. Processed eggs for marketing in Korea could be classified into two kinds. One is primary processed eggs including liquid eggs and egg powders. The other is secondary processed eggs which are further processed such as egg flake and egg curd. In addition to the above egg products, specific nutrient fortified eggs are produced through the modified feed formula and breeding techniques. The technologies developed so far including Korean patents are introduced. Convenient foods using egg and nutrient controlled eggs will be popular in the near future. For example, low cholesterol egg and polyunsaturated fatty acid fortified egg will be produced to meet the consumer demand. However, facing problems such as introducing egg quality grading systems and extending the short shelf-life of washed eggs should be solved as well.

Deep sea water is deeper than 200 m in depth and maintains cool temperatures. It is clean seawater not contaminated by E. coli and other general bacteria. Because deep sea water is a recyclable resource with high industrial value, activities for commercial use are vigorously developing. We investigated safety, quality characteristics, and mineral contents of prototype products using deep sea water as a substitute for a curing agent and compared it with existing commercially processed products. This study examined the potential of deep sea water as an alternative to curing agent solution. As a result, safety and quality characteristics of processed meat products with deep sea water were not different from commercially processed meat products, but mineral contents were higher in processed meat products with deep sea water. Deep sea water could be widely used as purity salt and purity minerals that can replace chemical substances such as chemical salts. A new, active food market using deep sea water will emerge in the near future.

Objectives: The purpose of this study was to investigate the eating behavior toward processed foods among college students who live in different types of residence. Methods: This is a cross-sectional study targeting a total of 476 college students living at home with their family, living in a rental house with self-boarding, living in a lodging house, and living in a dormitory. Eating behaviors, including preference and the frequency of processed food intake were surveyed and compared according to the type of residence. Results: The rate of skipping a meal was significantly higher among students who reported self-boarding than those living in other types of residences. The main reason for skipping meals was that they got up late. In the entire study population, the main reason for consuming processed food was easy-to-cook (33.8%) and the primary consideration for choosing processed food was the price (54.0%). The processed food the most favored by college students was the processed noodles; those living at home with their family or living in a dormitory preferred milk products; those living in a rental house with self-boarding or in a lodging house preferred confectionery, retort pouch, convenience food, and canned/bottled food. The frequency of processed food intake was significantly higher in the students who reported self-boarding than those living in other types of residences (p < 0.001). Conclusions: Students' preference toward processed foods differed according to their type of residence. The frequency of processed food intake was significantly higher in students who reported self-boarding indicating that the type of residence of student is associated with their choices and consumption of processed foods.

Camel milk plays a critical role in the diet of peoples belongs to the semi-arid and arid regions. Since prehistoric times, camel milk marketing was limited due to lacking the processing facilities in the camel-rearing areas, nomads practiced the self-consumption of raw and fermented camel milk. A better understanding of the techno-functional properties of camel milk is required for product improvement to address market and customer needs. Despite the superior nutraceutical and health promoting potential, limited camel dairy products are available compared to other bovines. It is a challenging impetus for the dairy industry to provide diversified camel dairy products to consumers with superior nutritional and functional qualities. The physicochemical behavior and characteristics of camel milk is different than the bovine milk, which poses processing and technological challenges. Traditionally camel milk is only processed into various fermented and non-fermented products; however, the production of commercially important dairy products (cheese, butter, yogurt, and milk powder) from camel milk still needs to be processed successfully. Therefore, the industrial processing and transformation of camel milk into various products, including fermented dairy products, pasteurized milk, milk powder, cheese, and other products, require the development of new technologies based on applied research. This review highlights camel milk's processing constraints and techno-functional properties while presenting the challenges associated with processing the milk into various dairy products. Future research directions to improve product quality have also been discussed.
