The purpose of this study was to determine the storage characteristics of Makphyun, a kind of rice cake, containing peach and Makgeolli. The effect of peach paste (0, 5, 10 or 20%) on the storage qualities of Makphyun was evaluated during storage at $20{\pm}2^{\circ}C$ for 3 days. As the amount of peach paste increased, the loss of water in peach Makphyun decreased during storage. The sugar concentration ($^{\circ}Brix$) increased with the amount of peach paste. Textural properties by TPA showed that the hardness of Makphyun containing 20% peach paste was the lowest among the treated samples. However, the hardness of all Makphyuns increased during storage, regardless of the amount of peach paste. In accordance with texture results, DSC (Differential Scanning Calorimetry) showed that the enthalpy of Makphyun with 20% peach addition was the lowest, demonstrating the delaying effect of peach paste on the retrogradation of rice cake. From these results, it was determined that the addition of peach to Makphyn extends shelf-life by delaying retrogradation.

The objective of this study was to develop peach Makphyun, a kind of rice cake, added with peach and Makgeolli. The effects of peach paste (0, 5, 10, or 20%) on quality characteristics of Makphyun were evaluated during storage at $20{\pm}2^{\circ}C$ for 3 days. As the concentration of peach paste increased, pH decreased and acidity increased. Reducing sugar contents (%) increased with the amount of peach paste. Hunter color b (yellowness) value of rice cake increased with increasing amount of peach paste, whereas L (lightness) and a (redness) values decreased. Contents of total phenols increased with increasing amount of peach paste. Antioxidant activities such as DPPH and hydroxyl radical scavenging activities of peach Makphyun decreased with increasing amount of peach paste. The sensory evaluation results showed that overall preference of Makphyun containing peach paste content of 20% is higher than other groups.

In this study, we aimed to increase the utilization of non-commercializable peach fruits collected during harvesting and distribution and to promote the transition of a high value-added industry. After producing pastes from the flesh of different peach varieties, we used these pastes as ingredients in the production of Kochujang. We then performed a comparative analysis on the quality characteristics of the peach-added Kochujang and commercially available Kochujang products. Peach-added Kochujang exhibited a lower pH and reduced sugar, salinity, reducing sugar, ash, and calorie content than those of commercially available Kochujang products. However, the Kochujang had slightly higher pH and moisture content than commercially available products due to high organic acid and moisture contents of peach flesh. In terms of content of inorganic elements, commercial Kochujang products exhibited higher sodium and magnesium content, whereas peach-added Kochujang had higher potassium content. In particular, the lower sodium and higher potassium content of peach-added Kochujang indicates that this product could be used as a functional food to prevent various diseases caused by excessive sodium intake among Koreans. After comparing the products in terms of phenol and flavonoid content, we concluded that ethanol extracts of peach-added Kochujang showed higher phenol content than those of the commercially available Kochujang products. In contrast, the distilled water extracts of peach Kochujang showed higher DPPH free radical scavenging activity than that of commercially available Kochujang products.

The Purpose of this study was to investigate the food preferences of college students of Korea. The survey was conducted on november, 1981 through the questionnaires. The subjects were 1184 male and 1241 female students of 9 universities. The results obtained were summarized as follows : 1) Preferences of staple foods : Cooked rice was preferred most by the subjects. Male liked rice more than female, whereas female liked bread and noodle more than male. Among the different kinds of rice, bread, and noodles, the following food items were favored by the subjects. (plain rice, red bean rice and soybean rice ; salad bread and vegetable bread ; Nangmyun and Bibim Kooksu). The foods not preferred were barley rice, instant noodle and soybean milk noodle. 2) Preference of side - dishes : Among the kinds of side - dishes by different preparation methods, stews were the most favored and the next favored were soups by the subiecls whereas female showed lower preference of soups than male subjects Most disliked kinds of side-dishes were changachi and moochim. For example, side-dishes which showed higher preference in each preparation method were stew (Kimchi stew and Soybean paste stew), soup (Beef soup and Seaweed soup), kimchi (Korean cabbage Kimchi), Bockeum (Sauted beef and Sauted Kimchil, cheon(Beef Cheon, fish Cheon), Kui(broiled saury and broiled yellow tail runner), Chorim(braised cuttle fish and braised fish cake), Namul(sliced radish, cucumber, and spinachi), and Changachi (dried radish). The side-dishes which showed lower preference were Alaskan pollack soup, soybean curd residue stew, cabbage Kimchi, liver Cheon, sauted liver, hairtail Chorim, radish rootNamul, and dried radish root Changachi. 3) Preferences of snacks. Fruits apple, peach, pear) were the most preferred snacks by the subjects. Male preferred ginsang tea whereas famale preferred coffee. Both bate and female subjects showed higher preference of milk and lower preference of sweets. 4) Preference of one-dish meals : No one dish meal were disliked by the subjects. Male liked Bockeum-Bab more than female, and female liked Mandukuk more than male subjects.
