  • This study investigated the quality characteristics of sea salt coated with coffee oil (SCO). Three-year-old salt was used after drying in an oven at $105^{\circ}C$ for 2 hours. Product A was composed of 100 g of sea salt and 8 g of coffee oil, product B was 100 g of sea salt and 16 g of coffee oil, and product C was 100 g of sea salt, 8 g of coffee oil, and 0.3 g of shell powder. The moisture content, ash content, color, peroxide value, acid value, and sensory evaluation of sea salt coated with coffee oil were determined monthly during 5 months of storage at room temperature. The contents of moisture and ash of SCO were 2~3% and 81~83%, respectively, but not significantly different during the storage period. Calcium content of product C was higher than that of product A or B. Coffee flavor in all SCO products was retained for 3 months. Hunter L, a, and b color values in SCO decreased with increasing storage period. However, redness and yellowness of product B were higher than those of other products. The peroxide and acid values of products A and C were lower than those of product B during storage period. Sensory evaluation during the storage period showed that quality of product A and C was maintained for 4 months, whereas product B was preserved for 3 months.

  • Nanotechnology in the food industry can increase the effectiveness of food ingredients. Nanotechnology can increase the bioavailability and absorption of bioactive compounds, enhance their stability, and improve the sensory quality of the product. Processed meat products are easily damaged due to bacterial activity. Advanced nanoemulsions as a meat preservative are nanoemulsions that can be used as preservative agents in meat products, particularly essential oil nanoemulsions, due to their antimicrobial and antioxidant properties. Its application is still limited to foods made from meat products. Therefore, this literature review examines nanoemulsion and its application in meat products and functionality improvement. Also, in the future, nanoemulsions in meat products must be made safe, and the government and businesses must work together to build consumer trust. It can be concluded that essential oil-based nanoemulsion has the potential to be used as an additive in meat products because it can kill bacteria, fight free radicals, improve flavor, and keep food fresh. Nanoemulsion is challenging in the meat industry because it can be toxic due to its tiny droplets (under 200 nm).

  • Numerous variables affect product cooling rate of pressure cooling system for fruits and vegetables. These include carton vent area, initial and desired final product temperature, flow rate and temperature of the cooling air, product size, shape and thermal properties and product configuration(whether in bulk or packed in shipping cartons). This study was carried out to determine the influence of each of these variables as they affect cooling time. The opening ratio and number of the vent hole were recomended as 4∼10% and 2∼4ea., respectively, for a minimum alt flow resistance and for a uniform air flow pattern. In the cooling experiment for tomatoes and mandarins, optimum air flow rate was 0.04 m3/min.kg in terms of energy saving. The cooling air temperature should be about 2$^{\circ}C$ less than the desired final product temperature for reducing cooling time.

  • In the relationship between a strategy and an outcome of new product development, a sample that can most give priority to a cost-price and a consumer is reflected in the result of financial affairs and non-financial affairs the most. A sample that can more give priority to a cost-price more is reflected in the result of financial affairs more. And a sample that can more give priority to a consumer is reflected in the result of non-financial affairs more. In accordance with this consequence, there is a close correlation in the analytical type between a new product developmental strategy and a new product developmental outcome.

  • Various sensory technologies have been used at different stages of product development. In this paper, the examples of sensory studies in teas and cosmetics were shown, and these could help to increase the contribution of sensory sciences to the development of products in the industry. In classical approach, descriptive analysis with trained panel and consumer acceptability test are very important to identify the sensorycharacteristicsthatdriveconsumeracceptability of products. Recently, some quick and easy sensory evaluation methods were introduced such as CATA (check-all-that-apply), sorting, and $Napping^{(R)}$, etc. to gather information about consumers' perception of the sensory characteristics of products. Although there are many sensory methodologies available in the product development phase, the most important thing is that these have to be correctly selected and designed for target consumers, products, and research purposes in order to develop a successful product.

  • Although the South Korean organic food market is in the infancy compared to other industrialized countries, Korean consumers'interest in organic food and retail stores devoting space to organic products have been rapidly increasing. Despite the fact of organic food popularity, the term "organic" is interpreted differently by individuals. As opposed to the US, Japan and the EU where have operated an integrated organic food labelling system, Korea has adopted complex organic labelling systems regulated by several different government bodies. As a result, complicated food labelling standards make consumers confused when purchasing organic foods. Furthermore, in terms of country of origin (COO), it is argued by a lot of researchers that COO effects vary from product to product and from country to country; moreover, other informational cues such as brand and price can influence COO effects. In modern society, COO labelling has been complicated, due to the sourcing, manufacturing and market locations of merchandise spread over the world. Accordingly, the evaluation of COO effects has become complex. In order to examine these issues, a quantitative research was selected to classify the commonfeatures of organic food consumers and construct statistics such as the extent to which people are aware of organic food and COO labellingvia a questionnaire which took place in two cities in Korea with a cluster sample of 161 organic food purchasers. As for the data analysis, one-way analysis of variance (ANOVA), T-tests, bivariate crosstatulations with Cramer's V were conducted,depending on the characteristics of variables and the assumptions the research data need to fit. It has been concluded that in general, Korean organic consumers comprehend the term "organic"in a closer way to the general concept rather than technical term, thus people do not appreciate environmentally labels which include organic food labels, although marital status influence the degree of label awareness, regardless of gender, age, education level and so on. Regarding COO effects on organic food, home organic products were Korean consumers'first choice over those from industrialized countries and developing nations. Specifically, in processed organic product category, domestically cultivated and processed organic products were absolutely preferred to leading national brands produced with imported ingredients and international brands. However, due to a lack of checks of ingredients' COO, consumers tend to purchase a leading national organic food brand, believing that it is a pure organic food sourced domestically. As a consequence, this research has suggested some important managerial implications and future research directions. In order to prevent consumer confusion when buying organic foods, it should be noted that consumers do not comprehend the organic food certifications, due to complicated labelling systems for organic produce and processed organic foods. Therefore, government bodies related to organic food distribution have to know consumers' perception of organic food labels and the significance of customer-oriented labels and reestablish labelling standards. Similarly, public advertising should be followed to raise public awareness of the labelling to enable customers to have the correct information. In addition, not only international marketers but also domestic marketers need to understand COO images and also the influence COO of ingredients has on the image of an organic product.

  • This study was carried out to investigate the effect of egg shell calcium salt types and egg shell membrane on calcium metabolism in rats. Sprague-Dawley male rats, 4 weeks of age, were fed on free-calcium diets for 2 weeks after adjustment period. Rats weighing approximately $247{\pm}2.3g$ were divided into 6 groups and were fed on the experimental diets containing 0.2% calcium for 4 weeks. Experimental groups were as follows; {ES(M+)} (egg shell powder diet with egg shell membrane), {ES(M-)} (egg shell powder diet without egg shell membrane), {AC(M+)} (egg shell calcium acetate diet with egg shell membrance), {AC(M-)} (egg shell calcium acetate diet without eg shell membrane), {GC(M+)} (egg shell calcium glucuronate diet with egg shell membrane) and {GC(M-)} (egg shell calcium glucuronate diet without egg shell membrane). Bone length of femur was significantly different by the types (p<0.05) of egg shell calcium salts. Bone mineral density of femur showed the highest level in AC(M-) group. Calcium content of femur and calcium absorption rate were higher in egg shell calcium salt groups than in eg shell powder groups. Calcium absorption rate and retention were significantly different (p<0.05) among the types of eg shell calcium salts and were higher in the AC(M-) group than in the other groups. Alkaline phosphatase activity, parathyroid hormone and osteocalcin levels of serum showed no significant difference among the experimental groups. From the above results, it is concluded that bioavailability of calcium is higher in groups of egg shell calcium salts compared to those in egg shell powder, even though egg shell membrane has no effect on calcium metabolism. Thus, these findings suggest the possibility of using egg shell calcium salts as a functional food material related to calcium metabolism.

  • Saururus chinensis Baill was reported to inhibit ${\alpha}-glucosidase$ in vitro and flatten postprandial increase in blood glucose in streptozotocin (STZ)-induced diabetic rats. We studied the effect of chronic consumption of S. chinensis Baill on blood glucose and lipid profile in STZ-induced diabetic male rats fed high fat diet. Male rats weighing 100-120 g were fed 30% fat diet with and without 10% freeze-dried leaves of S. chinensis Baill for 7 weeks after 1 week of adaptation. The rats were rendered diabetic by intravenous injection of STZ (60 mg/kg) after 6-week feeding of the assigned diets. At 1 week after the injection, the rats were sacrificed after an overnight fast. Plasma glucose ($380.2{\pm}14.4mg/dL$), total cholesterol ($93.9{\pm}7.9mg/dL$) and triglyceride levels ($123.6{\pm}7.5mg/dL$) of the S. chinensis Baill group were significantly lower than those of the control group ($418.1{\pm}12.0mg/dL,\;119.9{\pm}9.4mg/dL,\;152.0{\pm}10.3mg/dL$, respectively, p<0.05). Chronic consumption of S. chinesis Baill significantly decreased maltase activity of the small intestinal mucosa ($120.1{\pm}8.7U/g$) protein compared with the control group ($96.8{\pm}7.0U/g protein, p<0.05). These results suggest that S. chinensis Baill have hypoglycemic and hypolipidemic effects by inhibiting ${\alpha}-glucosidase$ activity in the animal model of diabetes mellitus.

  • This study evaluated the effects of adding levels of rice bran fiber on the chemical compositions, cooking characteristics and sensory properties of ground pork meat products. Meat products were produced with products containing 0% (control), 1%, 2%, 3%, 4%, and 5% and rice bran fiber. The control had the highest protein and fat contents, cooking loss, reduction in diameter, CIE L value and CIE a value of uncooked product, and CIE L value of cooked product. The meat product containing rice bran fiber had the higher ash, pH, and CIE b value than the controls. The addition of 5% rice bran fiber resulted in the lowest cooking loss and L value of cooked meat products. Meat product with 2% rice bran had the highest water content, water holding capacity, hardness, color, tenderness, juiciness values. There was a significant difference among the ground meat products with respect to sensory properties, and meat products containing 1% and 2% rice bran had higher overall acceptability than the other meat products.

  • The purpose of this study was to assess Korean and non-Korean customers' preferences with regards to Korean foods as well as their opinions concerning the commercialization of Korean foods. The subjects consisted of 268 Koreans and 217 non-Koreans in Seoul, Gyeonggi and Daejeon, Korea and in Texas in the United States. The respondents were asked to assess their preferences regarding 22 Korean food items using a 5-point scale (1: strongly dislike - 5: strongly like). Excluding responses with significant missing data, there were 485 usable responses. Data were analyzed using SPSS Windows (ver. 14.0) for descriptive analysis and t-test. Korean customers' perception and preferences regarding Korean foods were significantly higher than those of non-Korean customers (p<0.001). Among the 22 Korean food items, Galbi-gui (4.32) was chosen to be Koreans' favorite menu, whereas Bulgogi (4.25) was most preferred by non-Koreans. Patjuk was the least preferred by Koreans (3.37) and non-Koreans (3.18) alike. Regarding convenience food product equivalents of the 22 Korean foods, Koreans thought Bibimbap to be the bestseller while non-Koreans thought that Bulgogi was the most sold product. Korean and non-Korean mostly wanted to purchase Bibimbap and Bulgogi respectively, if Korean foods are commercialized as a convenience food. Koreans (44.4%) and non-Koreans (66.8%) reported "taste" as the most important factor when choosing a convenience food. Koreans chose "salty taste" (26.9%) and "simple cooking method" (23.1%), whereas non-Koreans chose "nutrition" (23.5%) and "hot taste" (21.2%) as aspects that require improvement in order to commercialize Korean foods.
