This study was undertaken to provide basic data to aid product development and marketing by identifying purchasing behaviors and performing Important Performance Analysis (IPA) according to the consumption values of rice cakes. This study was conducted on 426 consumers who purchased rice cakes. Analysis was performed to determine general characteristics, consumption behaviors, preference for rice cakes, material preferences for rice cake development, need for rice cake development, and importance and satisfaction when selecting rice cakes. Cluster analysis classified consumption values into three clusters. The high and middle consumption value groups contained the greatest proportions of consumers aged over fifty. The high and medium consumption value groups preferred rice cakes more than the low consumption value group. Higher rice cake consumption value was positively associated with the greater preference for rice cakes. Furthermore, the perceived need to develop rice cakes was greatest in the high consumption value group. In addition, importance and satisfaction were positively associated with consumption value. IPA analysis showed that the attributes that require continuous attention because of their contributions to importance and satisfaction were taste, quantity, and hygiene. Different rice cake marketing and product development strategies are required for different consumption values.
The objective of this study was to provide information regarding trends of rice consumption of Korean adults based on different meal types. Respondent reports 24-hour recall data from the Korean National Health and Nutrition Examination Survey were used to assess daily rice consumption and intake ratios of rice for different meal types and places of preparation. Rice intake had gradually decreased from 224.6 g in 1998 to 190 g in 2001 and to 179.4 g in 2005. The rice consumption of Korean adults decreased every year in all ages for all places of meal preparation in 2001 and 2005 compare to 1998. Analysis for each meal type showed that rice intake at breakfast had not considerably changed, but rice intake had decreased at lunch and dinner. While the rice consumption ratio at lunch and dinner decreased, it also decreased or did not change at snack times except for the 19-29 age groups. All the age groups revealed comparable change in the analysis for meal types. There was some diversity between all age divisions in daily rice intake depending on place of meal preparation. The rice consumption by place of meal preparation was generally highest at home, lowest at other places, but it decreased in all places. The rice consumption at home was highest in the over 50 age group, lowest in the 20-30 age group. These changes seem to be related to food intake patterns of rice and substitutional foods in the diets and development regarding socio-economic status. So the need for further study on differences in rice intake based on socioeconomic levels and age group are indicated.
Rice is staple grain of our people and at the same time it is major source of income for Korean farmers. But recently various problems in connection with rice arose such as declining consumption etc. for this reason not only government but also related agencies are discussing about expanding vice consumption. This study is an attempt to provide basic data required for developing rice food and method of cooking it as a measure for increasing rice consumption and far this purpose survey has been conducted on primary school students in connection with their level of recognition, preference far rice food as well as their understanding and their consciousness on issues related to this topic. In terms of level of recognition of rice food majority of students which were subjected to this study stated that either they knew names of about 39 types of rice foods shown or had experience of eating them. They also stated in answers to question related to dietary habit that they prefer rice foods. Their reply on taste of rice food was plain and neat. But it was found their level of recognition on our traditional rice foods such as Ssal Dasik (rice cookies), Ssal Jinbyung (rice cakes) and Buggumi (fried rice cakes) etc. was very low. In connection with questions on their understanding of rice and consciousness of problems related to rice it was revealed that more than majority of primary school students in this research had erroneous idea on reason for the need of our effort for expanding rice consumption. Accordingly in order to expand rice consumption it is necessary to develop educational program addressing subjects of cultural and nutritional effect value of rice, effect of rice consumption upon rural economy and its application to school education concurrently with persistent study in order to diversify rice food restaurants and to improve method of cooking.
Cooked rice is a staple food for Koreans which provides more than 60% of daily required energy. In 1960's, Koreans ate 600 g-800 g of cooked rice per meal and the energy obtained from cooked rice was almost more than 80% of the daily intake of energy. However, as the economy of Korea improved, the major industry has been shifted from agriculture to various manufacturing industries and the export of those products has been increased thus increasing the national income but decreasing the farming population and thus rice consumption have been decreased. It has been said that the decreased rice consumption is caused solely by decreased farming population but it can also be said that the decreased farming population is caused by decreased rice consumption. As the national income increases, the type of foods people consume have become diversified. Various processed foods such as convenience food or ready-to-eat food have been widespread, which are mostly made of wheat flour rather than rice.
The study examined dietary intake, satiety rate, and eating rate using rice bowls with an elevated bottom (diet rice bowl) and rice bowls with an elevated bottom and monitoring line (monitoring rice bowl). The monitoring rice bowl was used to help subjects monitor amounts they had eaten as they ate. Eighteen normal weight college female students participated in this study once a week for 2 weeks. Three hundred grams of fried rice in a diet rice bowl (1st week), and 300 g of fried rice in a monitoring rice bowl were served to the participants over 2 consecutive weeks. After each lunch, dietary intake, satiety rate, and eating rate were measured. The consumption amount of fried rice was 261.6 g in the diet rice bowl group, and 264.8 g in the monitoring rice bowl group. There was no significant difference in fried rice intake between the two groups. The satiety rate of fried rice in the monitoring rice bowl group was significantly higher than that of the diet rice bowl group after 1 hour and 2 hours (P<0.05). The eating rate of the diet rice bowl group (21.3 g/min) was significantly faster than that of the monitoring rice bowl group (18.7 g/min) (P<0.05). This result shows that food consumption monitoring can affect not only eating rate but also the subjective feelings of satiety after meal eating. Although more study is needed, these data suggest consumption monitoring in a rice bowl may help to control obesity and weight.
The purpose of this study was to investigate the consumption patterns of the Korean traditional rice cakes by general public. Self-administered questionnaires were collected from 511 residents in the Metropolitan area. Data were analysed by t-test, ANOVA and Chi-square. The result of the study can be summarized as follows: Generally, the rice cake was recognized as a 'good food' in all age groups. The reasons why they prefer the rice cakes were 'It tastes good' and 'It has been eaten from the past.' The time when they use the rice cake was mostly the holidays and events(or festivities). The female had more experiences than the male in making it. Songpyeon took the first place for them to have experiences to make. The consumption frequencies of rice cake were the more in females than in males. The higher the age, the more frequently they consumed. Injeolmi was the one which was purchased the most frequently. The place that they usually buy from was the rice cake shop around their house. The most important factor considering when they buy it was the taste. The reason why the frequency the rice cakes made for their direct consumption at home is gradually decreasing was "It is troublesome to make", and "It is complicated to make.
Power consumption, mesh size, moisture content, color difference, amylogram of rice flour milled with the water soaked rice were compared with that of rice using dry pin mill process. The rice was soaked in 23, 24, 25, 26% of water for 10hr, independently. The more rice had moisture content, the less power consumption was needed. Power consumption to mill the rice soaked in 25% of water was less than that of dry rice by 6.8kW/100Kg. Moisture content of rice flour from the rice soaked with 25% of water was 2% higher than that of rice flour from the rice soaked with 23% of, water. Population of flour particle from the rice soaked with 24-25% of water was 45.7∼46.25 of 60 mesh, 9.7∼10.4% of 80∼100 mesh and 7.7∼8.1% of 100 mesh. Gelatinization temperature of rice flour from the rice soaked with 23% and 24∼25% of water was 65.70C and 64.50C, independently. Temperature of rice flour from the rice soaked with 23% 24∼25% of water sith minimum viscosity was 85.50C and 88.4∼88.70C, independently. Brightness and whiteness of the rice flour from the rice soaked with 24∼25% of water were 95.90∼95.95 and 905.82∼95.94, independently. Brightness and whiteness of the rice flour from the soaked rice were 1.2 and 1.7 higher than that of rice flour from the dry rice, independently.
The purpose of this research was to investigate the relationship between white rice consumption and dietary intake, the risk of metabolic syndrome in Korean based on $1^{st}$ (1998), $4^{th}$ (2007~2009), $6^{th}$ (2013) KNHANES. This study included 25,799 subjects who were age 10 or over. Three groups(low, medium, high) were divided according to white rice consumption (per day). In the low group, the meat and oil intake were significantly higher than the high group. In the $1^{st}$ survey year, the BMI, waist circumstances, hypertriglyceridemia and fasting blood glucose in the high group were higher than other groups, however the $4^{th}$ and $6^{th}$ survey year showed no significant results. In the $1^{st}$ survey year the risk of waist circumstances was higher in the high white rice consumption group and also had high risk with hypertriglyceridemia. Since the lower white rice consumption in $4^{th}$ than $1^{st}$ survey year we found no significant results. But in the 6th survey year with the lowest white rice consumption the risk of high diastolic pressure was reduced in high group. Because continuously reduced white rice consumption meantime showed more intake of meat and oil, it can be concluded that defensive effects with the Korean health.
Rice has prevailed as a staple food in South Korea. Rice consumption has sharply shrunk nowadays. In the wake of COVID-19 Shock and the "untact" era, the instant rice market has significantly grown, and there is a possibility of solving the shrinking consumption of domestic rice. This study contributes to the development of rice consumption promotion strategies by examining the factors of purchasing instant rice based on the Hedonic Price Methodology. In particular, given the increase in online market, this study compares attribute values of product characteristics between online and offline markets. The empirical results show that calorie, brand, organic and functional products have positive effects on instant rice prices. The rate of carbohydrate, the PB and bundle attributes have negative effects on instant rice prices. The results also show that the magnitude of brand, bundle and PB attribute values are bigger in offline market while that of the number of multigrain attribute value is relatively bigger in online market. The organic attribute value is important regardless of marketing channels.
Power consumption, mesh size, moisture content, color difference, amylogram of rice flour milled with water soaked rice were compared with that of rice using dry pin mil process. Maximum water absorbance of rice was 35% for 2.5 hr. Power consumption to mill the soaked rice was less than of dry rice by 6.9kW/100Kg. Moisture content of rice flour from the water soaked rice was 2% higher than that of rice flour from dry rice. Population of flour particle was 52.9% of 60 mesh and 32.6% of 60∼80mesh. Gelatinization temperature of rice flour from the water soaked rice was 30C lower than that of rice flour from dry rice. Maximum and minimum viscosity of rice flour from the water soaked rice after boiling were 296 cps and 158 cps, independently. Brightness and whiteness of the rice flour from the water soaked rice were increased upto 10hr soaking and decreased after 17hr soaking. Brightness and whiteness of the rice flour were 96.17 and 96.02, independently.
