In Korea, confectionery refers to biscuits, snacks, chocolate, candy and gum. The first sweet in Korea is the Yumilkwa (oil-and-honey pastry) in the Goryeo Dynasty which was mentioned in history book, and is seen to be popular in medieval Korea. Korea's confectionery industry began in 1945 with the aid of the U.S. forces, Haitai Confectionery company produced sweets. The first confectionery product is 'Yeon yang gang'. In the 1970s and 1980s, the confectionery industry developed along with economic growth in Korea, and many of the products released at this time are still loved. Now the domestic market is saturated, sales of domestic confectionery companies are decreasing due to low-priced offers made by importers. It is necessary to develop products with high quality and brand power that can lead the market, and I think it is necessary to target the undeveloped market like the Halal market.

The purpose of the present study was to determine the effect of a chewing gum containing 70% xylitol and 0.23% Curcuma xanthorrhiza extract to remove dental plaque and reduce gingivitis when used as a supplement to daily toothbrushing for 3 weeks. The study group consisted of 75 adults with moderate gingvitis. Participants were divided into 3 groups(contol 1 group - Gum base, contol 2 group - 70% Xylitol, experiment group - 70% xylitol and 0.23% xanthorrhizol) and instructed to chew the study gum for 3 times daily for 3 weeks in addition to regular daily toothbrushing. Chewing xylitol/xanthorrhizol gum significantly reduced plaque index with significant difference by week 3(p<0.01). Gingival index and bleeding on probing were decreased in xy/ Curcuma xanthorrhiza extract group by 35.9% and 31.65% each in the same period. No adverse effects on the oral tissues were observed in any of the participants for the duration of the study. In conclusion, regular use of a chewing gum containing 70% xylitol and 0.23% Curcuma xanthorrhiza extract appears safe and effective for the removal of dental plaque and reduction of gingivitis when used in conjunction with daily toothbrushing.

In order to provide orange sac for off-season processing of sac-suspended orange juice, orange was processed into intermediate form of orange sac or segment, stored at $20^{\circ}C$ and after 5 months of storage the intermediate product was finally processed into sac-suspended orange juice. Adaptability of various process and packaging was assessed. Pasteurized orange sac and segment could be relatively stable in view of microbiological spoilage during 5 months of storage. Between pasteurization methods of hot fill process and each of in-pouch or in-can process, there is no difference in quality of preliminary processed product during storage and final sac-suspended orange juice. In packaging method, metal can gave the best result and the next was 3 ply (PE/AL/PET) pouch and the last 2 ply (PE/PET) pouch. Storage in segment form was superior to sac storage. Sensory evaluation revealed better scores in final product processed from stored orange sac or segment than in control (initially processed sac-suspended orange juice) except 2 ply packaged sac.

This study represents the marketing strategy of naturally fermented vinegar drink produced by a small business company located in Gangwon-do, the Republic of Korea. We surveyed about 200 potential customers in Seoul, Gyeonggi-do and Gyeongsangnam-do. Based on the survey result, we present the marketing strategy using the credited methodology, marketing mix(4P).

The effects of the yeast, Phaffia rhodozyme in the diet on growth, body composition, muscle elasticity and pigmentation of Israeli strain of common carp, colored carp and Nile tilapia were investigated. Ten percent of the yeast was added to semi purified diet as an experimental feed 1. Ten percent of brewers yeast in the semi purified diet (experimental feed 2) was tested for comparing the growth performance between two semi purified diets. A commercial diet was also used for the check of growth rate of the semi purified diets. All experimental fish were fed for 10 weeks. The weight gains among the experimental fish were not significantly different (P>0.05). There were not significantly different in body composition, muscle elasticity among the the fishes fed three experimental diets. There were significant differences (P<0.05) of pigment deposition in the muscle of Israeli strain of common can and on the skin of colored carp between treated and non treated group. But there were no differences of pigment deposition in flesh and skin of tilapia among the three diets.

Polygalacturonase(PG) and pectinesterase(PE) were extracted from Chinese cabbage and physicochemical properties of the enzymes were characterized. The preheating conditions for maximum retention of Kimchi texture were also studied. The activity of PE was highest at $50^{\circ}C$ and at 0.02M $CaCl_2$ but decreased in 0.2M $CaCl_2$, PG exhibited maximum activity at $65^{\circ}C$ with 0.3mM $CaCl_2$ but was inhibited by $CaCl_2$ at 0.5mM. Both of the enzymes, however, exhibited the maximum activity with 0.25M NaCl. Optimum preheating treatment was determined for minimum PG activity and maximum PE activity. Thus a maximum crispness and firmness was obtained with preheating in 0.05M $CaCl_2$ solution at $50^{\circ}C$ for 1.5hr results indicated that PE activity and calcium ion were very effective in preserving firmness.

To evaluate the methanol extract from Pinus strobus leave as a possible ingredient of health food, the sensory analysis and an animal experiment were designed using cookie, candy or chewing gum containing the methanol extract. Cookie, candy and chewing gum which contained 0.4%, 0.25% and 0.3% of the methanol extract, respectively, were prepared by Haitai Confectionary CO.. Sensory analysis of the products was evaluated by hedonic scale. Our results indicated that the addition of the methanol extract to the products provides better sensory perception in hedonic score and higher preference number than control, especially in candy and cookie. In the animal experiment, the chickens fed diet containing 10% of the cookie powder for 2 weeks exhibited a reduction of the serum cholesterol level by 18%, compared with the chickens fed basal diet. This result suggested that the methanol extract from P. strobus leave contained a potential ingredient to reduce the concentration of serum cholesterol. Therefore, extract from Pinus strobus leaves can be used as an ingredient of health food.

The physical and chemical properties of dry acorn starch(DS), defatted acorn starch (DFS) and reincorporated acorn starch(RIS) were investigated. Swelling power and solubility of all starch sample, were exhibited two stage behavior. It had a little change on the pasting temperature of DS and DFS but the peak viscosity and breakdown value of DFS was somewhat higher than those of DS and RIS. Flow behavior of gelatinized starch pastes showed a pseudoplastic behavior and flow behavior index was lower than unit The consistency coefficient showed concentration and temperature dependency. The activation energies of DS, DFS and RIS were from $1.70Kca1/g\;{\cdot}\;mol$ to $3.75Kca1/g\;{\cdot}\;mol$.
