Stewed pumpkin juice(SPJ) has recently become popular as a health drink, and its consumption is growing rapidly. Well ripened pumpkin was heated in a pressure cooker and squeezed to an extract and then packed in retort pouches. The ingredient of ginger, onion, jujube and boxthorn was added to samples of SPJ in order to observe the effect on the composition of SPJ during production and storage at 28oC for 60 days. The level of the main mineral(K) in pumpkin varied when the ingredients were added. The pH of control SPJ showed more changes than the SPJs with ingredients added, and there was almost no change in the samples with boxthorn. During storage, titrable acidity decreased in all samples, and the SPJs with ginger and jujube showed relatively little change compared to the samples of control SPJ and SPJ with onion. As for soluble solid and reducting sugar, the SPJs with jujube and boxthorn showed the highest reading. For carotenoid, the SPJs with jujube, ginger, boxthorn and onion listed according to the amount of carotenoid contained more total carotenoid than the control SPJ. Most of the carotenoid in pumpkin and its extract was found to be carotene by HPLC and Chandler's method. Sensory evaluation of the SPJ samples with ingredients revealed preference for the taste of the SPJs with jujube, ginger and boxthorn in declining order of preference. The taste of SPJs with ingredients added was generally preferent over the control SPJ except the case of SPJ with onion.

Objectives: This study investigated the utilization and satisfaction of lunchbox by considering the dietary lifestyle of the consumer, in order to refine the purchasing behavior of adults with experience in using lunchboxes, and to provide basic data for efficient menu configuration and direction towards improvement. Methods: A total of 600 adults in Seoul and Gyeonggi-do answered a self-administered questionnaire designed to investigate general characteristics, utilization, menu preference, satisfaction, prospection, and improvement of lunchbox, according to the dietary lifestyle. Results: The study subjects were classified into 5 groups: 'taste seeking group', 'safety seeking group', 'health seeking group', 'economic seeking group' and 'convenience seeking group. Considering purchase value of the lunchbox, the 'taste seeking group' had a high utilization rate (35.1%) for prices less than 4,000 won (P < 0.05). Lunchboxes were mainly purchased at the lunchbox store (43.3%) and convenience store (37.7%). The important factor that contributed to purchasing a lunchbox was taste (61.3%), which was highest in the 'taste seeking group' (P < 0.01). The 'health seeking group' showed the highest preference for the low-salt diet lunchbox menu (26.0%) (P < 0.05). The satisfaction of 'health seeking groups' was lowest when considering addition of condiments (2.34%), origin of ingredient (2.59%), and provided calorie (2.81%) (P < 0.05). The overall response indicated future use of the lunchbox (69.6%) (P < 0.01); 35.8% respondents recommended the purchase of lunchbox, where convenience of purchase was the highest factor contributing to recommendation (50.2%) (P < 0.05). Conclusions: Taken together, our results indicate that taste was emphasized in every group purchasing the lunch box. Convenience of purchase was the highest factor contributing to satisfaction, which was relatively low when considering addition of condiments, nutrition and origin of ingredients. We propose that it is necessary to improve the development of various menus for increasing satisfaction by selecting the right ingredients contributing to good health of the consumer.

Taste is classified into five types, each of which has evolved to play its respective role in mammalian survival. Sour taste is one of the important ways to judge whether food has gone bad, and the sour taste receptor (PKD2L1) is the gene behind it. Here, we investigated whether ʟ-pyroglutamic acid interacts with sour taste receptors through electrophysiology and mutation experiments using Xenopus oocytes. R299 of hPKD2L1 was revealed to be involved in ʟ-pyroglutamic acid binding in a concentration-dependent manner. As a result, it is possible to objectify the change in signal intensity according to the concentration of ʟ-pyroglutamic acid, an active ingredient involved in the taste of kimchi, at the molecular level. Since the taste of other ingredients can also be measured with the method used in this experiment, it is expected that an objective database of taste can be created.

This article examines the types and cooking methods for tteok (Korean rice cake) according to its sub-ingredients, as recorded in 18 old literatures of the Joseon dynasty (1392~1909). The sub-ingredients used in tteok during the Joseon dynasty were categorized into flowers, fruits, vegetables, Korean typical medicinal plants, and others. In the early, middle, and late eras of the Joseon dynasty, one, six, and 14 kinds of tteok were prepared using flowers as the sub-ingredient and two, seven, and 32 kinds of tteok were prepared using fruits, respectively. Three, seven, and 38 kinds of Tteok were prepared using vegetables as the sub-ingredient, while there were three, five and 15 kinds tteok prepared using Korean medicinal plants, respectively. One, five, and 13 kinds of tteok were prepared using other ingredients such as fish and seogi mushrooms in the early, middle, and late eras of the Joseon dynasty, respectively. The types of sub-ingredients and the resulting types of tteok increased throughout the Joseon dynasty, indicating that flowers and vegetables were preferred the most among tteok sub-ingredients. Tteoks using flower as the sub-ingredient, whajeon, were mostly jijin-tteok. The types of tteok and cooking methods using other sub-ingredients were discussed in terms of the type of sub-ingredients and their treatment to prepare tteok. The sub-ingredients were mixed with flour, which was the main ingredient for preparing tteok, or ground and shredded to prepare gomul for decorating and stuffing tteok, respectively. It seemed that the appearance and taste of tteok varied, thereby resulting in nutrient supplementation as the kinds of sub-ingredients increased throughout the Joseon dynasty. We expect that the recipes and ingredients as well as the cooking methods recorded in these old articles will contribute to those looking for a healthy life and, furthermore, to the globalization of tteok.

A type of Korean traditional cookies, yackwa is composed of ingredients which serve as good medicine to people. Further, it has a priceless value and possibility to be a healthy functional dessert. For this study, we developed variable yackwa, containing red-ginseng powder and green tea powder, in order to target the foreign market as well as to investigate the perception and preference of yackwa. The test sample for the control group, yackwa is made of flour, sugar, baking powder, sesame oil and alcohol. For the experimental group, yackwa contains red-ginseng and green tea powder (3, 6, 9, 12%). The investigation period was May 14th, 2013 and the total number of participants was 100. The investigation applied a consumer survey method by filling out a questionnaire while tasting 9 kinds of yackwa samples. They were used for frequency, one-way ANOVA and Pearson's correlation analysis with SPSS 19.0. In the yackwa perception survey, the result indicated that 52.0% of the customers replied 'Do not know well' and 'Do not know at all' which conveys that the perception of yackwa is very low. In contrast, the perception of the red-ginseng and green tea which are functional ingredients is high and the customers tend to prefer the taste and flavor of green tea than red-ginseng. And they prefer the yackwa containing 3% of red-ginseng and green tea powder compared to other ratio contents in the overall preference, color, taste, flavor, odor, degree of greasiness and texture. When people who have a higher perception of yackwa, they tended to prefer the color of red-ginseng yackwa and dislike the color of green tea yackwa. And the more people prefer the taste of green tea, the higher in overall preference, color, taste, flavor, and odor preference.
